The safe-haven hunt in 2022 : is Bitcoin the answer?

Is bitcoin a safe-haven? Powered by SUN ZU Lab

We revisit in this article a question studied by Sun Zu Lab in 2020 during the financial crisis caused by the Covid-19 pandemic: did bitcoin resist the market downturn better than other assets in 2022, and would it have been strategically interesting for investors to shift some of their positions to bitcoin before the downturn? the answer to these questions is still negative, as it was the case in 2020. We study in this analysis the behavior of various assets over the year 2022, specifically bitcoin, ether, equity markets (S&P 500), bond markets (US interest rates) and gold.

This result does not constitute an absolute answer to the intrinsic value of digital assets, but rather provides insights into a specific situation.

Economic context

2022 has been marked so far by the Russian invasion of Ukraine which, added to an economic context already weakened by the Covid-19 pandemic, has accentuated the slowdown of the world economy which could enter a long period of stagflation (low growth and high inflation). According to World Bank figures, global growth is expected to fall from 5.7% in 2021 to 2.9% in 2022, significantly lower than the 4.1% figure announced last January. We cannot help but notice the very visible parallel with the 1970s stagflation period. The comparison is striking: persistent supply disruptions that fuel inflation (Russian gas shortages, the effects of the prolonged severe lockdown in China on various value chains, etc.), coupled with the end of a long period of very accommodating monetary policy in major advanced economies: key interest rates close to 0%; Fed balance sheet in excess of $8.5 trillion (35% of US. GDP, an all-time record), etc. Added to this are projections of a slowdown in global growth and the fragility of emerging and developing countries in the face of the urging need to tighten monetary policies to curb inflation. 

In this unique context, we wanted to put ourselves in the shoes of investors to understand whether it is in their best interest to move from one asset class to another, and especially whether cryptos represent an effective safe haven in times of crisis. We model the S&P 500 by its most liquid ETF: Spider (ticker SPY, NAV as of 06/17/22: $378 billion). Gold is modeled by its most liquid physical ETF (ticker GLD, $63 billion NAV). U.S. government bonds are modeled by the iShares 7Y-10Y ETF (ticker IEF, $18 billion NAV). Prices are closing prices and all execution issues are neglected. Access considerations are also neglected: the products used here are easy to access, anyone can open a securities account with an online broker or a crypto exchange in a few days. Data is extracted from Yahoo finance. 

Finally, the « safe haven » concept reflects the idea that certain assets, financial or otherwise, provide a safe haven in the event of economic and financial turmoil. We often find in this category the US and German bonds, due to the almost absolute confidence in the strength of their economic fabric and their ability to always repay their debts. The Japanese Yen has often been considered a safe haven as well.

Performance

Without further ado, here is the relative performance of the 5 assets during 2022:

Bitcoin performance

The numbers speak for themselves: only gold managed a stable performance in 2022 (0.2%), while BTC or ETH under-performed the bond and equity markets (-55.8% and -70.5% respectively). 

Another way to answer the original question is to calculate the “flight to quality” percentage of investors who switched asset classes. Indeed, this type of behavior is extremely common; cautious investors forecasting the increase in interest rates and inflation at the beginning of the year might have chosen to move some of their positions to safer assets, such as gold, US sovereign bonds, or even Bitcoin? Let’s look at the results:

Bitcoin performance vs benchmarl

The red curve reads as follows: investors choosing to switch their position on 12/31/21 from gold to Bitcoin would have realized a loss of 56% between 12/31/21 and 6/17/22 (compared to a situation where they would have remained invested in gold). The graphs show exactly how much gain/loss was received for switching, depending on when the switch took place.

It appears that the choice to “pivot” from another asset to BTC has never paid off in 2022. Gold, on the other hand, has well played its role as a safe haven, providing positive gains at almost any time of the year on S&P > gold and bond > gold pivots.

Volatility

Rather than analyzing the assets’ volatility as defined by the classic financial formula, i.e. the annualized standard deviation of daily returns, let’s look at a more intuitive measure: the intra-day variation. We compute the 30-day moving average of daily amplitudes for the five assets.

The graph shows that over the year 2022, Bitcoin and Ether have varied on average between 3% and 8% from their highest to lowest price on a single day. In contrast, the S&P 500, gold and bonds only vary by 1% to 2.5% (or even less). Investors should keep in mind then that the amplitude of movements in crypto markets is 4 to 5 times greater than in traditional markets, which requires careful monitoring to deal with these risky assets.

Bitcoin's volatility

Liquidity

Finally, let’s analyze liquidity as characterized by daily volumes. This is a post-trade measure of liquidity, i.e. the liquidity that has been achieved through transactions. We could also study a pre-trade measure: the liquidity available before execution in the exchanges’ order books , which is a little more complex to compute.

The graphs below show average trading volumes (30-day moving average) in 2022, with 1-month volatility (annualized standard deviation) as the second axis:

The S&P 500 ETF is one of the most liquid instruments in the world, with $30 to $60 billion traded every day. The causal relationship between volatility and volume is immediately apparent.

Liquidity of Bitcoin by SUN ZU Lab

For the gold ETF GLD, we have daily trading volumes between $1 and $3.5 billion, but the causal relationship is still perfectly visible.

Liquidity of Bitcoin analysed by SUN ZU Lab

Regarding Bitcoin, we have first of all a confirmation of its very volatile character, with annualized volatility varying between 40% and 80%. This graph also raises discrepancies already made by Sun Zu Lab in 2020: it appears that the volatility/volume causality is still not respected, with peaks of volatility in February-March that are not accompanied by any increase in volume, and on the contrary periods like April when the volume seems to grow by itself!

The two circled areas on the chart are anomalies, likely due to the fact that the officially announced volumes are greatly overestimated and that the magnitude of phantom volumes varies over time. The S&P 500, gold and the bond ETF, not included here, show a rather stable “structural” liquidity: when the volatility peaks stop, the average volume goes back down to a base level.

Conclusion

The answer to the question “is BTC a credible alternative to the volatility of traditional markets?” is negative, again, over the year 2022. Unquestionably, gold and sovereign bonds are still the “safe haven” they have been for a long time. On the other hand, the liquidity of bitcoin (and ether) is still problematic; the volumes traded do not follow the same logic expressed historically by investors in the traditional markets.

Demystifying the Terra debacle


Terra Luna debacle

By Stéphane Reverre and Amine Mounazil

A stablecoin is a cryptocurrency whose value is “pegged” to the price of a reserve item, the US dollar being the most commonly used reserve asset. Stablecoins appeared for the first time in 2014, and have been gaining popularity since. Today, they are considered the backbone of the crypto ecosystem by providing an “on-risk” and “off-risk” alternative for cryptocurrencies. Moreover, their adoption is driven by the demand of traditional financial institutions and the larger crypto sector for a standard approach to leverage blockchain technology while avoiding related risks.

Thus, stablecoins address one of the fundamental issues with many mainstream cryptocurrencies: their extreme volatility, which makes them inadequate for real-world transactions. Altough competition is nothing new among stablecoins, “de-pegs” are an unwelcome and novel eventuality as different projects fight tooth and nail to source the liquidity required to keep their coins close to the promised pegged value ($1 most of the time).

In this piece, we first give a brief overview of stablecoin issuance, followed by an analysis of stablecoins from a macroeconomic standpoint, before introducing quantitative insights about the recent activity that led UST to depeg and spread contagion in the digital asset market.

A brief overview of stablecoin economics

To better understand the issuance of fiat-backed stablecoins, consider each stablecoin protocol as a financial organization similar to a bank with assets and liabilities. The reserve assets (monetary units or investment securities) and liabilities (issued tokens) are matched 1:1.

However, things are different in the case of crypto-collateralized stablecoins because of the volatility of the collateral. If the value of cryptocurrency reserves falls, the system may become undercollateralized. As a result, if liabilities are in dollar-equivalent, the 1:1 backing will not hold. One way to solve this problem, and to keep the entire system safe, is to make reserve assets significantly larger than liabilities (over-collateralize). Although their exact mechanisms differ, this is how the Maker (DAI) and the Synthetix
(sUSD) protocols manage their risk.

As for algorithmic stablecoins, they are based on the idea that maintaining the value of the stablecoin over time is possible through the right set of incentives offered to market participants, in response to market conditions. In other words, the protocol itself contains provisions to defend the peg directly, as in the case for Celo Dollar (cUSD) and TerraUSD ($UST).
When it comes to non-custodial stablecoins (i.e. stablecoin that do not hold physical collateral), there are five key hazards:

Each of these can cause the stablecoin value to fall, possibly to zero. Because they are not formally backed by collateral, algorithmic stables like $UST are especially vulnerable to collateral risk. When there is a loss of confidence, such as when the general crypto markets falls, it may lead to a bank run or “death spiral”.

The robustness of a stablecoin depends on its ability to maintain the peg by reducing the spread between its “market value” and its “theoretical value“, i.e. the value of the currency the coin is pegged to. This ability is supported by two elements: the quality of market makers and the depth of the orderbook.

Stablecoin macroeconomics

In legacy markets, a currency peg is a means of securing a currency’s stability by tying its exchange rate to another currency. A notable example is the peg of the Chinese Yuan to the dollar, managed by the Chinese Central Bank, or the Swiss franc, whose peg to the Euro snapped in 2015. Currency pegs allow governments to develop a stable trading environment free of volatility, and to effectively operate an active control of monetary flows (e.g. balance of payments, foreign direct investment etc). As a general rule, government’s foreign currency reserves must be large in order to maintain a peg. This is because, if the government has to appreciate/depreciate its own currency, it may have to do so in the open market with its own reserves, in addition to traditional tools such as raising/decreasing interest rates.

A stablecoin is in essence a digital asset designed to keep its value by being pegged to a fiat currency such as the dollar or the euro, a commodity such as gold or silver, or another crypto currency. To keep the peg, the money supply of stablecoins is extended and contracted. When the price of a stablecoin rises in relation to the peg, the stablecoin’s money supply expands. Similarly, if the price of a stablecoin falls in relation to the peg, the stablecoin’s money supply contracts.
One recurrent risk for stablecoins, or any pegged currency, is the threat of an attack aimed at breaking the peg and profiting from price discrepancies (Soros’ 92). This risk has been present in legacy markets long before the emergence of blockchain technology and decentralised finance (DeFi), and is illustrated in modern economic theory by the concept of the “impossible trinity”. The impossible trinity (or unholy
trilemma) states that an authority (say a central bank) can only have two of the following at the same time, but never all three:

  1. Free capital movement (i.e. absence of capital controls): citizens of a country can diversify their assets by investing overseas, thanks to capital mobility. It also invites foreign investors to invest in the country by bringing their resources and expertise.
  2. A fixed foreign exchange rate (i.e. a peg): a fluctuating currency rate, which is sometimes influenced by speculation, can be a cause of larger economic unpredictability. A steady rate also makes it easier for households and businesses to participate in the global economy and develop long-term plans.
  3. An independent monetary policy: when the economy is in a recession, the said authority can raise and lower interest rates, and when the economy is overheated, it can cut the money supply and raise interest rates.

We turn now back to our crypto eco-system. It is crucial to understand the tokenomics behind both assets before diving into a quantitative analysis of the $LUNA and $UST debacle. The underlying protocol, Terra, operates with two tokens ($LUNA and $UST), and incorporates a virtual automated market maker (AMM). The objective is to keep those tokens in balance to maintain the $UST stablecoin’s peg. In addition to the “algo” part, Terra is supported by the Luna Foundation Guard (LFG) and its reserves.

Market participants can mint (e.g. create) $UST on Terra by burning (e.g. destroying) an equal dollar-amount of $LUNA and are incentivized to do so. Consequently, the price of $LUNA rises as the demand for stablecoins rises: the change in $UST demand dictates how much $LUNA must be burned. As this amount is subsequently burned, supply decreases.

As it happens, $UST’s adoption since the end of 2021 has been parabolic, thanks to Anchor, Terra’s lending and borrowing protocol, which offered annual percentage yields (APY) as high as 19.5% on deposits. This, of course, has resulted in a reduction of $LUNA’s supply, which decreased by 5% in January 2022 alone:

Market activity quantitative insights

Now that we are somewhat familiar with the tokenomics of these protocols, we can better understand the market behavior by first reading market activity then looking at anomalies and microstructure analytics on [include venues & pairs].

Earlier this year, the Luna Foundation Guard (LFG) raised $1 billion through a sale of $LUNA (its native token) to form a $BTC reserve, in order to maintain Terra’s stability and fund future developments. The establishment of a $BTC reserve was meant to reduce the possibility of a death spiral. So, instead of having to mint $LUNA to arbitrage the price of $UST, users can now exchange $UST for $BTC on Terra.

Swap BTC and UST

In April again, the LFG acquired an additional 37,863 $BTC for ~$1.5 billion, while the Anchor APY was reduced to 18%. During the same period, a massive $UST sell-off happened on Curve and Binance resulting in a small depeg that was aggravated by the withdrawal of roughly $2 billion from Anchor. The unfavorable timing has led many participants to speculate this was a coordinated attack to drive the stablecoin to depeg in order to either cripple the Terra ecosystem or trigger some sort of contagion that would result in $BTC to dip.

Historically, every known stablecoin has broken its peg at some point. Moreover, statistical evidence* shows that $BTC volatility is statistically stable with a finite theoretical variance, whereas stablecoin volatility is statistically unstable and responds to $BTC volatility synchronously.

During the crash, the biggest volatility peak was observed at the beginning on May 9th at 6:20 pm. Many sale trades were observed, bringing the price down but immediately the market reacted and pushed the price back up, hence the high volatility. This selling pressure lasted exactly 1 min. The charts below show market activity for LUNA and UST on FTX, Kraken and Gemini over a few days prior to the crash (from May 5th to May 9th). Markets are still in “rebound mode” i.e., they tend to come back up even after severe down-moves, especially for UST:

Terra Luna price on FTX
Terra Luna price on Gemini
Terra Luna price on Kraken
Terra Luna price on Kraken UST

After May 9th, this “rebound” behavior disappears entirely, markets just “give-up” for LUNA, and UST trades at levels much lower than its peg value:

Terra Luna price on Gemini

When zooming closer at periods where activity is very surprising (to the point where our filters identify them as “anomalies”), here is one example of what we find on May 9th:

Terra Luna traded price and net traded volume with anomaly number 1

The biggest orders were sent in the middle of the crash. At 19:07 and 21:57:

Terra Luna traded price and net traded volume at 19:07
Terra Luna traded price and net traded volume

Following the crash, we observe a strong desynchronization between prices on FTX and Gemini, as can be seen below, where prices differed by more than $8 for several minutes. In addition, Gemini suffered a dramatic 9-fold decrease in market share on the LUNA-USD pair:

Terra Luna traded price on 05 10 2022
Terra Luna traded price on 05 10 2022 22:51
Terra luna rolling revenues

At the beginning of the crash, Gemini had a book twice as full as that of FTX, which can explain the large trades and other strange events observed on FTX. Logically, it was easier for manipulators to move the price on the market where the book was the thinnest. Following the crash however, the liquidity available in Gemini’s order book was almost non-existent.

Tether ($USDT), the crypto market’s largest stablecoin, also displayed symptoms of stress as Terra’s UST stablecoin imploded. It abruptly lost its $1 USD peg in early morning trading, falling as low as $0.95 before going back to $1.


Aftermath

On May 13th, block production on Terra was temporarily paused to prevent second-order consequences on network stability and governance caused by hyperinflating supply. Trading of $LUNA pairs was also suspended on some exchanges like Binance and Coinbase as it traded at less than a tick’s value.

In an effort to preserve the community and the developer ecosystem, Do Kwon (CEO of Terraform Labs, the company behind Terra) came up with the Terra Ecosystem Revival Plan. In order to significantly strengthen the liquidity around $UST peg, the LFG Council voted to loan $750M worth of $BTC to trading firms to help protect the $UST peg, and to loan $750M UST to accumulate $BTC as market conditions normalized. In addition, the foundation is looking to use its remaining assets to compensate current and past holders of $UST.

Distribution of LFG’s Reserve Assets as of 16 May 2022

On the 16th of May, Do Kwon published the Terra Ecosystem Revival Plan 2, where he imagines a fork in the Terra chain that will lead to a new chain without the algorithmic stablecoin. While the entire crypto-currency market has mixed opinions on this new experiment, it is clear once again that more scrutiny is needed to protect the small holder and protect the market from counterparty risk.

Liquidity Primer: an overview of Liquidity in Crypto Markets


The various types of crypto liquidity powered by sun zu lab

By Chadi El Adnani, Crypto Research Analyst @SUN ZU Lab

All seasoned investors know this for a fact: the first and foremost characteristic of a financial instrument is its liquidity. In its 4 th annual global crypto hedge fund report published recently, PWC confirmed that liquidity is indeed the most common consideration for crypto funds when choosing a trading venue (cited by 39% of respondents, see below). This percentage is significant and far above the next consideration, trading opportunities, at 18%. In the wake of this finding, we felt an overview of market liquidity with a focus on crypto markets was a good idea. Too often is the concept of liquidity overlooked or taken for granted, whereas in real life it is not only critical but difficult to quantify or elicit. In this article we provide general foundations about what liquidity is, its variations and manifestations

What is liquidity ?

We focus in this article on market liquidity, which is a different concept from monetary liquidity: a company’s ability to meet its current liability commitments. Liquidity is defined as the ability to buy or sell large quantities of an asset without significant adverse price movement. It is an important factor that investors need to assess before executing their trades, since it is a clear constraint on how quickly they can gain access to the market and subsequently how fast they can lock in a profit from a particular asset.

There exists different types of market liquidity:

We identify at SUN ZU Lab three different types of market liquidity: transaction liquidity (post-trade), order book liquidity (pre-trade) and invisible liquidity. Those notions are additive, in the sense that all three exist at the same time for a given instrument. Yet there is a timing dependency between them: invisible liquidity needs to become visible (pre-trade) before it can be consumed (post-trade).

Derivatives markets, whether in crypto or TradFi, enjoy far more liquidity than spot markets. The Bitcoin futures market, for example, saw average monthly turnover of $2 trillion at its peak, a far greater figure than BTC spot markets’ volumes. Liquidity is not only variable in time, it is also distributed in space across multiple venues. Our data shows for example that BTC trading volumes are fragmented across exchanges, as seen in the graph below (limited to 5 exchanges, and in reality there are many more creating an even higher degree of fragmentation).

Transaction liquidity:

Transaction liquidity refers to liquidity that has been expressed through actual trading volumes. This is an important indicator as high trading volumes usually imply less difficulty to buy or sell large quantities. Among the most liquid markets we can cite the forex market, thought to be the most liquid in the world as major currency pairs are traded by governments, banks, and even individuals. The stocks and commodities markets are very liquid as well, although intuitively no large cap or bond will ever be as liquid as a national currency.

Source: data from Yahoo Finance

In the graph above, we show daily trading volumes in 2022 for the S&P 500’s most liquid ETF, Spider SPY, as well as BTC-USD and ETH-USD. The S&P 500 ETF is one of the most liquid instruments in the world, with $30 to $60 billion traded every day. Data shows that Bitcoin and Ether’s daily trading volumes vary in range between $10 and $40 billion.

These figures however need to be taken with a grain of salt due to various sources reporting that officially announced crypto trading volumes are greatly overestimated with the magnitude of fake volumes varying over time.

Order book liquidity (pre-trade):

Order book liquidity represents the total nominal (price * quantity) visibly offered across all available trading venues. This liquidity materialises as different buy/sell quantities sent by investors at different prices. Across all buy orders, the best price is referred to as “best bid”, and the “best offer” on the other side across selling orders. The mid price is quite logically the middle of those two.

A visible order book represents the underlying supply and demand of an asset in the form of individual bid and ask orders. To illustrate this, here is a chart compiled by SUN ZU Lab showing how average liquidity aggregates around mid-price for BTC-USD on three main exchanges: Bitstamp, Kraken and Binance-US on the 22 nd of June, 2022.

Crypto Liquidity | Average market depth powered by SUN ZU Lab

Source: SUN ZU Lab data

The chart reads as follows: each bar represents the average quantity of BTC (in number of BTC) offered for buy/sell orders. For example, there were on average 200 BTC offered for sale at 80bps from mid-price on the three exchanges against around 210 BTC bid offers at -80bps from the mid-price.

Order books communicate information about investors expectations and appetite. In particular there appears a new concept to qualify liquidity: the bid-ask spread, which is the difference between the highest price a buyer is willing to pay for an asset and the lowest price a seller is willing to accept. The magnitude of this spread gives a good indication about an asset’s liquidity. For example a large spread indicate poor offer and/or demand, and incidentally may drive the volatility higher. Conversely a narrow spread is an indication of a deeper market where investor’s interest is high, and volume potentially abundant for buyers and sellers to execute their trades. Bid-ask spreads for Bitcoin, for example, used to be higher than 10% in the early days of crypto, but they have dropped massively to as low as 10bps on the main exchanges as crypto adoption, investor interest and trading volumes increased over time.

Invisible liquidity:

We refer to invisible liquidity as all forms of liquidity that is not captured in public trades or order books. Note for example that liquidity exposed to a limited set of investors would qualify here as invisible liquidity (more on this below).
In general terms, the taxonomy of “invisible liquidity” is extremely difficult to establish as it depends on the structure of the market. In markets where OTC activity is high, those trades and the interaction of brokers with their client are compartments of invisible liquidity.
One could argue that those compartments divert liquidity away from other pools, yet not all investors have access to it. In markets where OTC is not developed, those liquidity pools simply do not exist.

In the world of crypto, we distinguish the following categories:

Non-communicated, invisible orders: quantities available for trading that are yet to be communicated by investors to the markets. There is virtually no way to quantify these volumes as they only exist in a theoretical state in strategy books of portfolio managers.

Communicated, invisible orders: we put in this category for example trading activity of dark pools, also known as Alternative Trading Systems (ATS). These are private marketplaces where investors place buy and sell orders, without the venue disclosing available prices or volumes. Liquidity has found its way to the marketplace, it is just not visible (by anybody).

Communicated, partially-visible orders: quantities available for purchase or sale, expressed through an Indication of Interest (IOI), which refers to an investor’s non-binding interest in a security, usually communicated to a broker. In traditional markets, IOI are heavily regulated because, depending on applicable rules, they constitute visible or invisible liquidity. The regulators’ particular interest on this
compartment stems from the fact that liquidity visible only by a few agents is easily manipulable.

DeFi liquidity: this is liquidity placed on decentralized exchanges (DEXs) without being incorporated into order books. We will dive more in detail into how liquidity pools in DEXs work in another article.

On-Chain Liquidity: centralized exchanges (CEXs) rely on the “order book” mechanism to enable off-chain transactions: aggregate positions are “written” on chain only when investors transfer their positions out of exchanges (and de facto reclaim ownership of those on their wallets). Pure on-chain transactions today account for a relatively small percentage of total volumes. Decentralized exchanges (DEXs) are another form of on-chain liquidity, that relies on smart contracts to execute trades automatically, recorded directly (and immediately) on blockchains.

Data from Chainalysis shows that DEXs have surpassed CEXs in terms of on-chain transaction volume in January 2021, with a $175 billion volume sent on-chain to CEXs from April 2021 to April 2022, vs. a $224 billion volume sent to DEXs during the same period.

Peer-to-Peer Liquidity: P2P is a type of crypto exchange trading that allows traders to trade directly with one another without the need for a centralized third party to facilitate the transactions. This method allows exchanging parties to select a preferred offer and trade directly without using an automated engine to execute transactions.

Liquidity risks

The main liquidity risk associated to markets is for investors not to be able to enter/exit their positions due to a lack of sellers/buyers offering a fair price. One of the markets where this type of risk is the most visible is the real estate market. During times of economic turmoil or bad real estate market conditions, it could become impossible to find a buyer at the right price even though the property may have obvious value. A perfect example for this is the experience of NBA superstar Michael Jordan in trying to sell his Chicago mansion that has been on the market for 10 years already! The over-equipped luxurious house was originally listed for $29 million, before the owner was obliged to cut the price nearly in half overtime to try and match market expectations.

There is also another psychological effect that comes into play with illiquidity; the longer an asset is listed for sale, the more potential buyers are keen to second-guess their decision as the lack of interest and competition over the asset drives its value lower.

All of this has been extensively studied in traditional finance, and has become known as the “liquidity premium”: there is a clear relationship between price and liquidity. The higher the liquidity, the higher the price. This is the reason why real-estate prices are often subject to discount when economic conditions are under stress. We provide links to research articles about this subject in the appendix.

Conclusion

Liquidity is one of the most important concepts for individuals, institutional investors as well as exchanges and market makers. Despite holding high-value assets, any of these entities may experience a liquidity crunch if such assets cannot be sold within a short period. This is turn create heavy pressure on prices.

Top crypto projects’ tokens such as BTC, ETH, BNB or SOL appear to have reached a reasonable level of liquidity, but this is not the case for the vast majority of tokens that are only listed on one or two exchanges, with very low daily trading volumes and market depths. Above all, liquidity of the entire crypto market is still nowhere near liquidity levels visible in traditional markets.

Transaction Cost Analysis: the answer to all hidden costs behind crypto trading (1/2)


Transaction Cost Analysis by Sun ZU Lab

By Chadi El Adnani, Crypto Research Analyst @SUN ZU Lab

The “odd-eighth quotes” phenomenon

To introduce this article about Transaction Cost Analysis, we first revisit a very famous historical case. Before decimalization, the US stock market tick size used to vary by increments of 12.5 cents. This means that all prices were quoted in eighths of a dollar (ex. $12 or $12 1/8). However, on May 26 and 27, 1994, several US national newspapers reported an article that first appeared in the Journal of Finance (“Why Do NASDAQ Market Makers Avoid Odd-Eighth Quotes?”, by Christie, Harris and Schultz) raising the question of the width of the range of prices quoted by NASDAQ market makers. The researchers had found that the prices quoted to investors were almost systematically 1/4 ($0.25) apart, thus avoiding the minimum allowable 1/8 spread ($0.125)

To get a first grasp of the implications of this situation, we need to highlight that the range quoted by market makers is a good indication of the maximal margin they intend to capture. So by quoting a stock at $12 – $12 1/4 (i.e. they are willing to buy at $12 and sell at $12.25), instead of the allowed $12 1/8 – $12 1/4 range, market makers are refusing to decrease their margin bellow $0.25. So what would prevent market makers from avoiding odd-eighth quotes on 70 out of 100 actively traded NASDAQ securities, including Apple Computer and Lotus Development? The authors found no explanation and concluded that the situation was probably the result of implicit collusion among the participants to maintain wide spreads.

Surprisingly, On May 27, dealers in Amgen, Cisco Systems, and Microsoft sharply increased their use of odd-eighth quotes leading effective spreads to fall “magically” by nearly 50%, this pattern was repeated for Apple Computer the following trading day. Noticing these weird trends, the same authors published a new article a few months later to reconduct their investigation (“Why did NASDAQ Market Makers Stop Avoiding Odd-Eighth Quote?”). Using individual dealer quotes for Apple and Microsoft, the authors found that virtually all dealers moved in unison to adopt odd-eighth quotes.

These strange findings led thousands of individual investors to file a class-action lawsuit against 30 brokerage firms, including Merrill Lynch, Goldman Sachs and Morgan Stanley, which agreed in 1997 to pay about $900 million in what was called at the time the biggest settlement ever of a price-fixing lawsuit. 

What is Transaction Cost Analysis?

What the researchers behind the article have provided is part of what is known nowadays as Transaction Cost Analysis (TCA). Transaction costs have become a relevant issue in Europe for example since 2007 with the implementation of MiFID (Markets in Financial Instruments Directive). The introduction of the best execution obligation gave TCA a central role, aiming for investment firms to “take all reasonable steps to obtain the best possible result when executing orders for their clients”. Moreover, MiFID’s Article 21 of Level 1 and Article 45 of Level 2 require investment firms to provide their clients with “appropriate information” about their execution policies. Clients wishing to select a firm to deal with from among a competing group need to have sight of the relevant firms’ execution policies in order to evaluate whether a particular investment strategy is suitable. By requiring ex-ante disclosure of the execution policy, MiFID addresses clients’ information needs; they should always be able to pay the lowest possible net cost (or receive the highest possible net proceeds).

Transaction Cost Analysis (TCA) is the study of trade prices to determine whether trades are arranged at favourable prices (low prices for purchases and high prices for sales). The difference between the cost of the transaction at the time the manager decided to execute it and the actual cost is at the heart of TCA, including all operating charges, spreads, commissions and fees. The resulting differential is called “slippage”.

There are usually 9 components identifiable when dealing with transaction costs, they can be classified as per the following chart:

Conclusion

The same transaction costs exist for crypto trading as well but suffer from a severe lack of transparency. The Markets in Crypto-assets (MiCA) regulation in its latest version comes however with a “best execution” obligation that should force digital assets service providers down the same path as their TradFi peers. This obligation should come with extensive quantitative analytics of order execution prices, leading to increased competition among trading venues and liquidity providers. When that day comes, institutional and retail crypto investors should be able to rely on Sun Zu Lab’s advanced and completely independent liquidity analytics to provide much-needed transparency to the crypto ecosystem. 

In the next part of this article to be published, we will look at pre and post-trade TCA and analyse how this process actually works and how it helps an investment manager save money.

What is Tokenomics and why does it matter?


A brief historical perspective to better understand the stakes behind tokenomics

Let’s start this article with the famous experience of Philip II, King of Spain in the 16th century, with the Eldorado discovery and the massive rise in inflation that followed throughout the entirety of Europe!  

In the 16th century, Spain conquered Latin America and discovered an immeasurable wealth within gold and silver mines. The kingdom hit the jackpot and its financial deficits appeared long behind it. This wasn’t the case nevertheless; the problem came from the fact that the Crown of Spain was over-indebted to many European creditors, leading the massive silver and gold discoveries to only make a quick passage through Spain before enriching the coffers of its French and Dutch neighbours. The European market ended up being flooded with coins, so that the immense Spanish wealth was diminished relative to other European kingdoms.

In the end, the excessive amount of silver and gold imported, and above all distributed, in Europe caused an important devaluation of what Philip II could think of as his Eldorado. A better financial management could have allowed him to preserve his reserves of invaluable minerals and thus be able to develop on a more important scale of time his fabulous treasure.

This story shows the importance of the quantity put into circulation on the valuation of an asset. This analysis works perfectly for the cryptocurrency market as well, any analysis of an asset’s ecosystem requires careful attention to the notions of quantity in circulation, total quantity and inflation management.

Inflation and the importance of tokenomics

While the media usually describes inflation as a rise in the price of everyday consumer goods, it is in reality the value of money that tends to fall rather than prices getting higher. This notion of inflation is at the heart of tokenomics, a merger of “token” and “economics” used to refer to all the elements that make a particular cryptocurrency valuable and interesting to investors. In this regard, there exist two predominant models: deflationary and inflationary tokens.

This is the model used by Bitcoin, i.e. a fixed total supply and less and less money issued over time. Many cryptocurrencies are governed under this model, like Solana, Litecoin, Tron, and many others alongside the king of cryptos.

In the case of Bitcoin, for example, a block is mined about every 10 minutes, rewarding the miner 6.25 BTC (when Bitcoin started it was 50 BTC per block, then 25, 12.5, 6.25, etc). The reward is halved every 210K blocks, leading to a halving every 4 years with the 10 minutes mining-time per block assumption. Without changes to the protocol, the final Bitcoin will be mined around the year 2140.

Many blockchains have been coded without incorporating a limited amount of token issuance. This choice can be made for a variety of reasons, usually involving the use to be made of the blockchain in question. The Ethereum protocol for example operates under this model. However, some mechanisms are put in place to limit inflation, or even to create a deflationary system.

This is the objective of the implementation of future updates of the Ethereum network: while the annual rate of ETH tokens issuance is currently equal to nearly 4.5%, the switch from Proof of Work to Proof of Stake should allow developers to reduce this rate to less than 1%. The network introduced as well a burn mechanism, meaning that part of the fees paid by Ethereum users in the future will not be returned to validators, but will be removed altogether. This could not only achieve a balance with the issuance rate, but potentially lead to a decrease in the number of tokens in circulation in case of high network usage.

Both models have their strengths and weaknesses with good justifications behind their use. For example, the Ethereum white paper indicates that a stable issuance rate would prevent the excessive concentration of wealth in the hands of a few actors/validators. Whereas Bitcoin’s deflationary system, as previously stated, allowed for the growing development of its ecosystem by paying miners large amounts of Bitcoin when it was not worth the tens of thousands of dollars it is worth today.

More generally, it is always a good idea to look into a project’s tokenomics before getting involved. This can help answer questions like:

Main differences between deflationary and inflationary tokens:

Solana case study

Let’s take a deep dive into one of the most prominent blockchains’ tokenomics. Solana has a native token called SOL that has two primary use cases within the network:

The Solana team distributed tokens in five different funding rounds, four of which were private sales. These private sales began in Q1 2019 and culminated in a $20 million Series A led by Multicoin Capital, announced in July 2019. Additional participants included Distributed Global, BlockTower Capital, Foundation Capital, Blockchange VC, Slow Ventures, NEO Global Capital, Passport Capital, and Rockaway Ventures. The firms received SOL tokens in exchange for their investments, although the number of tokens allocated to investors was not disclosed.

The initial distribution of SOL tokens was as follows:

Source: compiled by SUN ZU Lab from web sources

According to Messari data, vesting schedules were as follows: Solana’s three pre-launch private sales all came with a nine-month lockup after the network launched. The project’s public auction sale (held in March 2020) did not come with a lockup schedule, and the SOL tokens distributed in that sale were fully liquid once the network launched. The founder’s allocation (13% of the initial supply) was also subject to a nine-month lockup post-network launch. After the lockup period ends, these tokens will vest monthly for another two years (expected to fully vest by January 2023). This last clause is a good protection for investors as team members’ tokens are locked-up for a longer period. The Grant Pool and Community Reserve (both overseen by the Solana Foundation) contain ~39% of the initial SOL supply combined. These allocations began to vest in small amounts since Solana’s mainnet launch.

Inflation stands at an initial annual inflation rate of 8%. However, this inflation rate will decrease at an annual rate of 15% (“dis-inflation rate”). The inflation decrease is thus non-linear and much more important in the first years. Solana’s inflation rate will continue to decrease until it reaches an annual rate of 1.5%, which the network should reach in about ten years or 2031. 1.5% will remain the long-term inflation rate for Solana unless the network’s governance system votes to change it.

Proposed Inflation schedule curve – Source: https://docs.solana.com/inflation/inflation_schedule

Major identified issues with current projects’ tokenomics

Using the Solana example, we can see that more than 50% of the tokens in circulation are concentrated, during a long period after the project’s launch, in the hands of the core team, VCs and early investors. This is hardly an exception to Solana as similar distributions are very common within the blockchain ecosystem projects. Can we talk seriously about the benefits of blockchain decentralization with such capital and governance concentration, without forgetting technical knowledge concentration as well?

Blockchain projects often come with varying lock-up periods that can last from less than a year to five years for early investors and the founding team, who usually cash out their investments after this period. What we identify as a significant issue after the end of the lock-up period is the huge and asymmetric risk-return transfer between this first group, which realized a pretty good return on their initial investments and are completely de-risked at this stage, and retail investors joining the project at a stage where core decision-makers are no longer incentivised to ensure the well-functioning of the project.

Cryptocurrency projects often use ICOs (Initial Coin Offering), among other fundraising techniques, to raise funds through the issue of crypto-assets in exchange for either fiat currency or an established cryptocurrency like bitcoin or ether. The issuing entity usually accounts for digital assets collected as an intangible asset, or as a financial instrument in the case of stablecoins for example as they are redeemable for cash. The accounting for tokens distributed on the other hand depends on the promise given to investors under the terms of the ICO, which could include: free or discounted access to the entity’s goods or services for a specified or indefinite period of time; a share of the profits of the entity or access to an exchange through which it can transact with other users of the exchange in buying goods or services. Digital asset projects may also offer equity tokens, which are a type of security tokens that work more like a traditional stock asset, giving their holders some form of ownership in their investments. The use of these equity instruments remains restricted nevertheless, raising the question of the rights and guarantees given to retail investors in particular in exchange for the funds given to the cryptocurrency project?   

What we refer to as double-dipping practices, in this case, relates to VCs investing in cryptocurrency projects and realising important capital gains on their equity shares as well as digital token holdings. This privilege is almost unique to the cryptocurrency ecosystem, raising some questions again about asymmetric information advantages against retail investors: compared to traditional VC funding, crypto VC investors enjoy a double economic as well as governance advantage, having control over token and equity.


Conclusion:

Tokenomics is an important aspect of cryptocurrency which covers almost anything to do with the token. Professional as well as retail investors should spend a lot of time studying a project’s tokenomics before investing to be well aware of the financial and governance rights attributed to them via the token purchase. There is an absolute need in our view for regulation on this particular topic to evolve in order to provide better transparency and eventually protection levels for investors.

Tether Reserves: at it again


So much for “Unrivaled transparency”

As a capital market professional, I have expressed before (here) how skeptical I was about Tether and its so-called “transparency”. For all intent and purposes, Tether looks more and more like a traditional bank with “fractional reserves”, a very ancient and old-fashioned way of operating a banking business, in which the bank doesn’t hold reserves for all the money it has issued (ignoring for a second the underlying fraud that this situation constitutes in the case of Tether). For a newcomer supporting the total disruption of finance as we know it, the resurgence of a centuries-old business model is somewhat ironic. What’s even more ironic is that the old way in banking is fundamentally built on trust. Remove trust and the entire system collapses through bank runs. The blockchain technology is supposed to take us away from traditional trusted third parties. And yet here we are, asking questions about Tether reserves, which fundamentally Tether cannot answer without the certification of…a trusted third-party.


As requested in the settlement with the Attorney General of the State of New York, Tether just disclosed the breakdown of its reserves as of 3/31/2021, here. The reader will appreciate the conciseness of this report,1 single page, 2 charts — no more, no less. We are not lost in details. Considering the annual report of any decent bank today is 400-page long and quite incomprehensible, the fact that Tether operates outside any sort of regulation simplifies the task. It has been said before: the list of gaps is staggering — no risk analysis, no indication of yield, no performance measurement, no mention of who is in charge, etc, etc. And still, no audit certification, no contact information, no signatory. Good luck to all of us with questions.

The story has been picked up by mainstream media, for example, the Financial Times a few days ago (“Tether says its reserves are backed by cash to the tune of . . . 2.9%”). That anybody would buy Tether in these circumstances is extraordinary. And this is exactly what one of our clients asked us last week: “if Tether is such a big concern, why does it still trade at $1? If markets were even somewhat efficient, its value would have adjusted with the perceived risk no?”. Indeed, this is a legitimate question. After reflecting on this for a few days, here are some answers, the only ones I can provide in fact:


Where is the truth? What is going on with Tether, and more importantly do we really have a way of knowing? Probably no without the help of a proper due diligence process, and only regulators have the power to make this happen. 

Crypto Risk Assessment: Way to Go

Last autumn I had the pleasure of giving an introductory course on financial risk management at IAE in Bordeaux. The purpose was to provide students with a general understanding of what financial risk looks like, and what it means to “manage” risk. 

Naturally, as part of the course, I had to offer a typology of financial risks i.e. a list as exhaustive as possible of all risks, their magnitude, likelihood, and to some extent the way to mitigate them. 

The result is the table below: it is naturally a simplification, but not an excessive one. Listed are the risks by type, with the space of instruments they apply to, some simple ideas about possible mitigation, the first order of magnitude, and examples of things gone bad whenever possible:

The magnitude scale is as follows (applied to capital at risk, whether it is a nominal amount for cash products or notional amounts for derivatives):

The individual links do not appear in the image, so here they are with underlying URLs:


Now it is beyond the scope of this article to go deeply into each risk, but one remark is in order: the table above could be much redder, and was such in fact not too long ago. Indeed, many of the risks have turned out to be manageable because the industry has structured itself to address them. I have written before about the operational governance in capital markets, this governance is the result of a long slow evolution. A lot of money has been invested (and still is) into market infrastructure, to vent several types of risks out of the system.

A few examples to illustrate the point: independent clearinghouses, heavy regulation of depository institutions, SWIFT massaging infrastructure, standardized master agreements (notably from professional organizations such as ISDA, ISLA, ICMA, etc), delivery-vs-payment settlement to name but a few.

What’s the situation in the realm of digital assets? Are we better or worse in an ecosystem that is much younger, and not yet dominated by highly-capitalized international financial institutions? Supposedly fintech are nimbler and consequently more adaptable.

The table below summarizes the main differences (well, at least as I see them): 

Like before the links have disappeared in the picture, here they are:

Naturally the above is subjective, and I am quite certain many bitcoin proponents would object. Regardless, there is little doubt that it is redder than the previous table, and for good reasons: most of the infrastructure in place in traditional markets doesn’t exist in crypto. For example, exchanges are “custodial” i.e. you need to deposit both fiat and crypto before you can trade. There is no single (cash) exchange in traditional markets that accepts deposits from its members and/or participants.

The question of settlement and money flows is addressed somewhere else in the industry (that’s exactly why clearinghouses have come to exist, and those do require deposits from the select firms they accept as members). Even when you settle a trade with a stable coin such as Tether, you still carry the specific risk of Tether. The same applies to derivatives: in the absence of a central clearinghouse, exchanges manage the entire process, and there can be no assurance for an investor that he will be able to recoup his funds should the exchange go under. 


Reward doesn’t go without risk and vice versa. The reason why crypto is such a gold rush right now is exactly this: risk is high, widespread, and probably very poorly understood. Investors who made a lot of money should probably ask themselves: what risk did I really take? Am I out of the woods now? Which one(s) do I want to take going forward?

To end on a positive note, one risk has disappeared, and that’s for the better: the systemic one. If bitcoin went to 0, or if a large crypto participant went under, chances are the overall economy would not suffer much. This incidentally is why regulators worldwide still do not want to intervene. They are vigilant, suspicious because part of their mandate is to protect the “small” guy. But from a risk standpoint, they can still afford to let the crypto space mature and regulate itself.

Arbitrage on digital assets

How we built a quantitative indicator on market integration

There is a lot of talk about arbitrage in the world of digital assets. Myth or reality?

We at SUN ZU Lab wanted to provide the necessary tools to examine this question and provide reliable answers. Therefore we designed a quantitative indicator to detect macro arbitrage opportunities when markets fall out of synchronization. Our goal was to produce an indicator that captures the existence and broad magnitude of price discrepancies between markets on the same asset. A secondary objective was to determine to what extend those discrepancies appear and disappear based on market behavior (e.g. volatility) or geography (e.g. region).

To that effect, we built our indicator which we denote “arbitrage index” (AI) calculated as follows. Let amp(1’, t) be the 1-minute volume-weighted average price (VWAP) amplitude:

i and j are indices on markets. VWAP is the volume-weighted average price on a given market at time t. In plain English, amp(1’,t) is the ratio of the highest VWAP to the lowest VWAP across all included exchanges for a given 1’ interval. The arbitrage index (AI) is the hourly average of all amp(1’,t).

This indicator fulfills our need:

Market professionals will find that this indicator is too “macro” and not precise enough. Indeed, it is true that this methodology leads to only a gross estimation of real-life price discrepancies. A rigorous analysis based on tick-by-tick analysis would yield much more robust estimates, as they are seen in real time by active traders (by the way we do agree and will move in that direction!). Nevertheless our indicator does a fair job at showing relative market integration, both in space and in time, which is exactly its objective.

For the purpose of practical calculations, markets have been grouped in three regions:

The chart below presents the index globally (top), by region (bottom left), and inter-region (bottom right):

SUN ZU Lab’s Arbitrage Index

It appears the index differs significantly from 1 during the period, which clearly shows that market are far from being closely integrated.

The following charts show volatility, and the cross-reference between the index and volatility:

Even though the relationship between the two doesn’t appear to be straightforward, there is a strong sense that the indicator does indeed increase for volatile prices. At the same time it is fair to conclude that volatility is not the only factor responsible for prices being out of sync.

We go one step further in our analysis and produce a “theoretical P&L” based on opportunities we detect. What is an opportunity? As it happens crypto exchanges produce a useful indicator for each trade: the side of the trade (bid or ask). Based on this indicator it becomes possible to isolate price discrepancies that could be seen as an arbitrage opportunity by participants. Here is our methodology:

This methodology leads to the following results:

Hourly number and average size of opportunities

And subsequently to the following theoretical P&L:

Overall, we believe our AI indicator is a reliable and significant measure of market integration, and we will produce a bi-monthly report incorporating the above results (and more!) for BTC as well as other digital assets. Investors seriously curious about cryptocurrencies and digital assets may find in this a way to monitor market efficiency as it evolves through time and across trading venues.

Price discrepancies in the world of digital assets

What a strange market!

We at SUN ZU Lab are striving to gain a deep understanding of how the markets for digital assets function, to help our clients achieve their investment strategy through better execution. Based on our long (very long!) experience of traditional markets, we have started looking closely at liquidity and arbitrage. The interested reader will find a sample of our efforts here.

We subsequently turned our attention to the basic behavior of trading venues, trying to understand if there was something special there compared to what we knew of traditional well-established exchanges. Thus we started looking at small-scale data to try and detect unusual patterns. Because we aimed at being as systematic and unbiased as possible, we devised automated filters to isolate those events.

The result is our latest weekly “market anomalies” report, which presents events selected because of a sharp price movement or heavy volume. For each of those events, we look at price discrepancies and/or volume patterns. Well, the results are quite surprising, here are three examples abstracted from our report dated March 26th for bitcoin.

Price anomaly #1: -1.53% on 3/21/21 between 09:43 and 09:44 UTC

By looking at the most significant price movements over a 1-minute interval we can detect periods where markets are moving “fast”, and those moments are very good candidates to detect unusual price or volume patterns.

As an illustration, below is the 1-minute charts of BTC prices and volumes on 5 venues, between 9:43 and 9:44 on 3/21:

To get a better sense of price discrepancies, we chart the maximum price difference in the interval between the lower and higher price:

It is fairly clear that during this period, prices on the different venues were far from being “aligned”. In another of our reports, we look at price discrepancies and arbitrage opportunities at a macro scale, but here at the tick level, we suspect there are opportunities to be grabbed.

Or are there? Let’s have a closer look at the strangeness of this picture:

I have numbered 4 surprising patterns:

  1. a small blip of Kraken vs. other exchanges: what is happening on Kraken at that precise time? BTC is trading there several times $100 below other markets. What is unexpected is not the fact that one venue experiences sharp movements independently from the others. The surprising part is that none of the other venues moves in sync. We strongly suspect that there are many arbitragers out there sharpening their trading algorithms to specifically identify and exploit those situations. Why was there no change anywhere but on Kraken? One possible explanation is that there was not enough time to capture that opportunity. Well, this is unlikely because as it happens all venues traded repeatedly during a window that lasted several seconds. Another explanation is that bid/ask spreads were very wide and trades occurring on one side of the spread appeared to be out of sync. Investigating that idea requires tick-by-tick order book data, and a little bit of work (but do not worry we are on it). Another explanation could be that some of the trades on Kraken were fake trades, or that they happened outside the regular bid/ask spread if they were “pre-negotiated” (a particular status that indicates a block trade on traditional exchanges). In any case, we would need a little bit more information from the exchange to be able to conclude.
  2. Coinbase price seems to be lagging: as surprising as it looks, this type of pattern is quite straightforward to explain. It results from the lag in order book positioning on Coinbase. The bid/ask spreads on other exchanges adapts more rapidly, which means that prices tend to lag and adjust at the last moment (i.e. the next transaction) on Coinbase. Again confirming this initial intuition requires tick-by-tick order book data, but nothing worrying there.
  3. Bitfinex at $100 to $150 discount compared to other markets: well, that’s a big one. The discount on Bitfinex appears 20 seconds before but stays stubbornly high. It appears and doesn’t disappear for some time (see #2 anomaly below where it exists with the same magnitude). A discount like this would rarely appear on traditional markets (stocks, derivatives, bonds, etc) because market participants would arbitrage it away sooner rather than later. If it persists as it does here, it is not your typical liquidity discount. Indeed, it is associated with Bitfinex, other exchanges keep trading in sync (more or less). Therefore the underlying reason is to be found with the specifics of Bitfinex: are there trading constraints that would induce investors to severely discount BTC on that platform compared to another? Indeed our research confirms that this discount appears quite regularly, and never turns into a premium. Investors should therefore be mindful and investigate further the underlying reasons that could create a recurring anomaly like this (as will we!).
  4. $80 price difference between Kraken on one side and Bitstamp/Binance on the other: whereas Kraken was at the bottom before, it is now trading higher than the others. Coinbase is lagging, Bitfinex is still at a discount, but Bitstamp/Binance and Kraken repeatedly trade at a $100 difference for 6 to 7 seconds. Are those real arbitrage transactions or “visual effects” due to lagging or fake transactions? As before we need tick-by-tick order books to conclude, and possible further information from the exchanges if everything else proves insufficient.

For the sake of curiosity, below are two more anomalies abstracted from our report. The reader will find the Bitfinex discount again, and long, recurring inter-venue price discrepancies. NB: the last anomaly is one detected through our volume filters, hence labeled “volume anomaly”. Volumes on Bitfinex appear as extreme outliers, accompanied by price dips that have a very small impact on other venues.

Price anomaly #2: +1.11% on 3/21/21 between 09:44 and 09:45 UTC

Volume anomaly #1: 706 BTC on 3/21/24 between 22:15 and 22:16

Well, we knew digital asset venues were not so closely integrated, but here we have a very detailed view of anomalies that are curious and result in significant price discrepancies. To track some of those anomalies regularly, we will produce a weekly report incorporating the above results (and more!) for BTC as well as other digital assets. Investors seriously curious about cryptocurrencies and digital assets may find in those a way to monitor market efficiency and as it evolves through time and across trading venues.

Our take on the liquidity of digital assets

A more systematic approach to liquidity monitoring

We at SUN ZU Lab have a deep curiosity about digital assets. Like everyone else, we follow bitcoin’s saga, with a volatility which, after all, is probably regarded more as a source or opportunity than a risk to be curtailed.

As we have written before (here and here), if digital assets were to constitute only a new source of liquidity, they would be an invaluable development in modern finance. Whoever has spent time on capital markets knows that liquidity is an elusive target at best. After decades of electronic trading, intense innovation, and regulatory adjustments, attracting and retaining liquidity remains as difficult as ever. Exchanges and trading venues worldwide know it firsthand, their primary responsibility is indeed to attract liquidity, one way or the other. Many have adopted “market-making” schemes whereby they basically waive fees and sometimes actually pay for participants to contribute orders in their central order book.

Liquidity is defined as the ability to rapidly buy and sell a product for significant size without adverse impact on its price. Note that this definition is not limited to financial products. Real estate for example is a very illiquid asset class. There is a constant trade-off between the time it takes to conclude a transaction and price improvements each party is willing to concede.

Liquidity is a very desirable feature on any developing market, and digital assets are no exception. If the price of bitcoin catches the front news almost every day now, reported trading volumes are also a big part of the story. Taken at face value, those suggest that bitcoin is at least as liquid as some of the most heavily traded traditional instruments (see here and here for a more detailed analysis on the subject).

Even though this is most certainly not true, in great part because volumes are massively manipulated (an x10 factor is commonly hypothesized), the bottom line is that public attention for bitcoin and more generally digital assets is bound to translate into more and more trading activity i.e. more liquidity. In fact, most of it may not even be visible: as investors stand by for the right price to buy or sell, they do not necessarily register their interest with a broker or on the order book of an exchange.

Where is liquidity to be found? There are dozens of venues, on-chain, off-chain, centralized, decentralized. Which venue should you turn to to find the most liquid market? Should you trade on several markets, if so which ones? What price and/or size can you expect if you include 1, 5, 15 markets in your shopping list?

Those are fundamental questions for investors, retail and professional alike. The marketplace is evolving so quickly and in so many different places that it is virtually impossible to follow all relevant developments. That’s where we at SUN ZU Lab, want to help. We started out with a mission: promote a truly institutional standard in the analysis of digital asset liquidity. Our quantitative research is meant to offer a dissected view of liquidity in time and space, so interested parties can get a sense of macro and micro trends to make better-informed decisions for their trading flow.

We had to start somewhere, so we decided to launch our product on BTC, including for the time being 3 markets: Coinbase, Kraken, and Bitstamp. We will be producing 3 reports: one on liquidity, another one will look at market integration (i.e. the existence of price discrepancies between different venues), and the third at what we call market anomalies (i.e. events for which price or volume is an outlier). [Register for our newsletter if you want to hear from us and receive a free sample!]

Let’s look here at the liquidity report. It is a quantitative dissection at liquidity over a 2 week period and will be produced twice a month. Our intention is to present rigorous information to qualify and quantify liquidity dynamics both intraday and over the observed period.

Here is the list of indicators we look at, abstracted from the report over the last 2 weeks in January:

Price chart with volume-at-price histogram

This chart is a necessary introduction, we absolutely need to have a sense of how the market has moved over the period, and at what price points have traders concentrated their activity. The volume-at-price add-on on the right side is an elegant way to present this information.

Daily traded volume and intraday traded volume, by venue

Those two charts are fairly standard representations of volumes. We present both views to determine whether there are intraday patterns that have developed over the observed window. In particular, we could expect higher volumes when Asian and/or US markets open. Quite naturally we need to address also the question of the relative partition between exchanges:

Volume partition by exchange
Intraday and daily annualized volatility, by venue

Similarly to volumes, we plot both the intraday and daily volatility to monitor whether intraday patterns developed. Despite the fact that the charts are very similar on distinct venues, we decided to keep them all, to make anomalies between markets stand out, should some come up.

Intraday and daily mean trade size, by venue

The average trade size is a very important feature of liquidity dynamics. It is dependant on a number of factors, such as the type of investors (retail, institutional), the pricing structure of the exchange (fixed vs. variable fees, caps on per-order fees), time of day, etc. We found in our research that infrequent large trades tend to alter the readability of the average, therefore we decided to include the median as well:

Intraday and daily median trade size, by venue

Believe it or not, we think there are many more questions that we should be asking. For example: how does trade size vary with volatility? with the bid-ask spread? We will absolutely incorporate the relevant metrics to answer those questions in due course.

Participation indicators, by venue

Those two charts give two measures of market participation. First, we answer the question: how much volume does it take on a given day to fill a $10M order? As you can see it takes anywhere from 1% to 3% of the daily volume, on each exchange taken independently. Practitioners in traditional markets advise their clients to never cross the 15%~20% threshold. In the case of BTC on those three exchanges, roughly 10 investors with a significant order would be enough to “drain” available liquidity. The second chart is an examination of the same question, with a shorter time frame (1 hour), and a smaller size ($100K). Markets seem to be amply capable of absorbing repeated $100K orders.

Intraday arket impact, by venue

This chart is a slightly different take on market impact. It answers a different question: how much adverse price movement would a $100K market order create? This gives a measure of market depth, which as you can see is fairly stable in time but quite different across venues.

Intraday ratio between traded and available volume, by exchange

By definition, each trade “consumes” part of the visible liquidity. What ratio of the liquidity available is consumed, and how fast is it replenished? The chart gives an answer intraday. As can be seen, there seems to be a somewhat constant rate of consumption and replenishment, something which is somewhat surprising. Again, we will absolutely look at this in deeper detail in due course.

Volume available at best limits, by venue

This chart presents a view of the total size available at best limits, in each of the individual order books. It is useful to monitor absolute levels of “aggressiveness” from market participants, and patterns in the overall migration, if any, from one venue to the next.

Intraday mean price and time between transactions, by venue

Those two charts present an introduction to order book velocity. Each venue has its core client base, and those may have very different trading habits. Those habits are also constrained by venue-specific factors such as commissions, API throughput, matching engine performance, etc. Investors may gain valuable insights by qualifying each venue’s reactiveness and specific velocity.

Limit Order Book distribution at +/- 400 bps and +/- 100 bps from mid-price, by venue

Those charts present the distribution of each order book around mid-price, for a depth of 100 bps and 400 bps. There is a wealth of information to be extracted from those distributions. Here are two examples.

First, they indicate how participants think about risk beyond the first limits: are they placing a lot of orders away from mid? if so, are those significant compared to the best limits?

Second, how does each venue compare? Am I more likely to find liquidity at 50 bps from mid on Coinbase or Kraken? What about 100 bps?

Market makers, speculators, institutional investors have very different trading strategies. Market makers may be interested in price discrepancies, which would lead them to participate symmetrically from mid-price. Institutions may be more buyers or sellers at different times. In each case, they would presumably occupy one side more than the other. Although the averaging in the above charts provides a lot in readability, it is also the source of much “compression”. We have a lot more to say on order book dynamics, and in fact, it will be the subject of an entirely new report soon!

Popular wisdom would have that a trending market shows asymmetry in liquidity. Well, unfortunately, this is not quite as simple as that. The graph above represents the order book imbalance by trading venue. Order book imbalance is defined as (Qa — Qb)/(Qa + Qb), where Qa is the total quantity, available at 100 bps from mid on the offer, and Qb is the total quantity available at 100 bps from mid on the bid.

Imbalance oscillates between -1 and +1: a market with no bid (Qb = 0) has an imbalance of +1, and -1 for a market with no offer (Qa = 0). An imbalance close to 1 means the order book is dominated by offers and vice-versa.

It is very apparent that the three exchanges have very different imbalances. At 100 bps market depth, Coinbase is mostly an “offer” market (with variability), whereas Kraken and Bitstamp are mostly “bid”.

Average and Intraday market depth, by venue

Total visible liquidity is a very natural question: how many bitcoins are available in each order book? Those two charts present two different answers to that question. On the left, absolute size at 100 bps, on the right intraday depth at 10bps. Those can help provide first-order estimates of impact: 100 BTC can be executed with a max impact of 50 bps; at any time, an order of 10 BTC should not be filled more than 10~15 bps from mid.

Intraday and daily weighted spread, by venue

Of course, no study of liquidity would be complete without spread analysis. Above are time series of the weighted spread, showing intraday and daily dynamics. Unsurprisingly the weighted spread deteriorates quickly with volatility (early days in the chart). The charts below enable comparison between a simple spread and a measure weighted by the total quantity on best limits (bid + offer):

Spread and weighted spread distributions, by venue. NB: for enhanced readability Y-axis is logarithmic.

It can be seen quite easily that exchanges have very different order books.

Now this is a long list of charts and tables. You may get a sense that a lot of it is repetitive. We would argue that it is not, quite the contrary. As was said earlier liquidity is an elusive parameter, and in the world of digital assets it is bound to evolve very quickly. Monitoring and understanding it appears to us an important prerequisite for traders already active in the space, or even for “crypto curious” i.e. investors or institutions interested in the subject but not yet in a position to transact.
