Exchange-traded funds (ETFs) have transformed modern financial markets by offering a unique combination of diversification, liquidity, and transparency. These funds appeal to both individual and institutional investors. Recently, a new class of ETFs has gained attention: crypto ETFs. Focusing on digital assets such as Bitcoin, Ethereum, and Solana, these ETFs have generated unprecedented interest.
This article explores ETFs, explains how they work, and explores the reasons for their growing popularity in the cryptocurrency world.
What is an ETF?
An Exchange-Traded Fund (ETF) is a publicly traded investment fund that holds a basket of assets. Unlike a mutual fund, which trades at the end of each day at the closing price, an ETF trades in real time throughout the day, like a stock.
Diversification: An ETF allows investors to access a diversified range of assets by purchasing a single share. For example, an ETF can track a stock index, a specific sector, or even an asset class like gold or bonds.
Liquidity: ETFs are liquid and can be bought or sold at any time during market hours. This provides significant flexibility to investors, especially in volatile markets.
Transparency: ETFs disclose the composition of their portfolios daily, allowing investors to know exactly what they own.
How an ETF works:
The mechanism of an ETF is based on a network of market makers, liquidity providers, and reference indices.
Creation and Redemption: ETFs are created and redeemed in “blocks” called creation units, typically consisting of 50,000 or more shares. These units are created by financial institutions called authorized participants (APs). When an AP wants to create an ETF, it purchases the underlying assets in the specific proportions required by the fund, and exchanges them for shares of the ETF. Conversely, when an AP wants to redeem an ETF, it exchanges the shares for the underlying assets.
Arbitrage: One of the key mechanisms that keeps an ETF’s price close to its net asset value (NAV) is arbitrage. If an ETF’s market price deviates from its NAV, APs step in to buy or sell the underlying assets to bring the price back to fair value.
How an ETF Works
Here is a simplified chart that illustrates the mechanism of ETF creation and redemption. (Note: this text is a placeholder for a real chart.)
Creation: Authorized Participants (APs) purchase the underlying assets and exchange them for ETF shares with the ETF issuer.
Redemption: APs exchange ETF shares for the underlying assets from the ETF issuer.
Arbitrage: If the ETF price deviates from the value of the underlying assets (NAV), APs step in to buy or sell the assets and bring the price back to fair value.
The Financial Mechanisms of ETFs: An In-Depth Look
ETFs (Exchange-Traded Funds) are complex financial instruments that require a thorough understanding of the underlying calculation mechanisms to fully understand how they work. These financial products combine elements of asset management and market finance, while being listed on the stock exchange like individual stocks.
How ETFs Work and Calculations
An ETF typically tracks a benchmark index, such as the S&P 500 for stocks, or specific indices for sectors, commodities, or cryptocurrencies. Calculating the value of an ETF is based on several fundamental elements:
Net Asset Value (NAV):
The net asset value is the sum of the value of the fund's underlying assets divided by the total number of shares outstanding. The basic formula is:
For example, if an ETF holds shares of an index, the NAV is calculated by taking the sum of the products of each share (its market value) and the number of shares held by the ETF, then dividing that sum by the total number of shares in the ETF.
Tracking Error :
Tracking error measures the difference between the ETF's performance and that of the benchmark index it tracks. It is calculated as the standard deviation of the differences in returns between the ETF and the index over a given period:
A low tracking error indicates that the ETF is effectively tracking the index. Investors scrutinize this figure to ensure that the ETF is not straying from its objective.
Total Expense Ratio (TER):
The TER measures the annual costs associated with managing the ETF, expressed as a percentage of net assets. These costs include management fees, marketing fees, administration fees, etc. The TER affects the overall performance of the ETF, as it is deducted from the net asset value.
Performance after fees = Gross performance − TER
A lower TER often means more efficient management, although this is not always the case.
Contributions in Kind and Redemptions:
ETFs also operate through a contribution-in-kind and redemption mechanism, where large financial institutions (called APs, Authorized Participants) exchange baskets of securities for ETF shares, or vice versa. This keeps the value of the ETF close to its net asset value and ensures the liquidity of the product.
For example, if an ETF is listed at a price higher than its NAV, APs will buy the underlying securities and exchange them for new shares of the ETF, increasing the supply of the ETF and bringing the price back to its correct level.
Example Calculation for a Bitcoin ETF
Let’s take the hypothetical example of an ETF tracking the price of Bitcoin. Let’s say this ETF holds 100 bitcoins, and there are 10,000 shares outstanding.
(Please note, this is just an example. The figures given are to facilitate the calculation and do not reflect reality.)
Calculation from NAV:
If the price of Bitcoin is $30,000, the NAV of the ETF would be:
Impact of TER:
Let’s assume a TER of 1%. The effective performance for investors will be reduced by this percentage. If Bitcoin gains 10% in one year, the after-fee performance for the ETF would be:
Performance after fees = 10% − 1% = 9%
For those who want to know more about the financial mechanisms and mathematical formulas of ETFs, I highly recommend the book “Financial Mathematics” by Pierre Devolder, Mathilde Fox, Francis Vaguener
This book offers an in-depth analysis of ETFs, with examples of financial calculations. The mathematical formulas presented here are explained in detail in the book.
Why the Craze for Crypto ETFs?
Crypto ETFs have attracted considerable attention for several reasons, ranging from ease of access to regulation to transparency.
Simplified Access: For many investors, buying cryptocurrencies directly can be complex, requiring digital wallets, specialized exchanges, and secure private key management. A crypto ETF simplifies this process by allowing investors to buy shares in a fund that holds cryptocurrencies, without having to directly manage the digital assets.
Regulation and Trust: Crypto ETFs are regulated, which provides an extra layer of security for investors. Institutions like BlackRock or Grayscale, which offer crypto ETFs, are subject to strict regulations, which instills confidence in traditional investors who might otherwise be hesitant to venture into the crypto market.
Liquidity and Flexibility: Just like traditional ETFs, crypto ETFs offer daily liquidity and can be traded at any time during market hours. This allows investors to enter and exit cryptocurrency positions without the complications associated with traditional crypto exchanges.
Examples of Crypto ETFs
To better understand how crypto ETFs work, let’s look at some real-world examples.
Bitcoin ETF: The Bitcoin ETF is arguably the most well-known and sought-after. It tracks the performance of Bitcoin, allowing investors to gain exposure to the first and largest cryptocurrency without having to hold it directly. For example, the ProShares Bitcoin Strategy ETF (BITO) is an ETF that tracks Bitcoin futures contracts, allowing investors to gain exposure to Bitcoin through traditional markets.
Ethereum ETF: Ethereum, the second-largest cryptocurrency by market cap, also has its own ETFs, such as Grayscale’s Ethereum ETF. These funds give investors exposure to Ethereum, a cryptocurrency that is at the heart of decentralized applications and smart contracts.
Solana ETF: More recently, ETFs tied to digital assets like Solana have emerged. Solana is a blockchain that stands out for its high transaction speed and low costs. Solana-based ETFs allow investors to bet on the future of fast and scalable blockchains without having to directly manage Solana.
Crypto ETFs have become a crucial gateway for traditional investors looking to gain exposure to the cryptocurrency market without the technical complexities. Their regulated structure, liquidity, and ease of use make them an attractive choice, especially for those who prefer well-regulated financial products.
However, like any financial instrument, crypto ETFs carry risks. Extreme fluctuations in cryptocurrency markets can result in significant volatility in ETFs. Therefore, they are best suited for investors with adequate risk tolerance.
In conclusion, crypto ETFs represent a natural evolution in the investment space, merging the innovation of digital assets with the proven structure of exchange-traded funds. For savvy investors, they offer a new way to participate in the cryptocurrency revolution while enjoying the familiarity and benefits of a traditional financial product.
