ETF Liquidity: Definition and Importance

Zarith Sofea · 18 Mar 7.2K Views



Although sometimes misinterpreted, liquidity is one of the most significant characteristics of exchange-traded funds (ETFs). The ease with which shares of an ETF can be purchased and sold without affecting the ETF's market value is referred to as its liquidity. Put differently, an ETF with high liquidity facilitates rapid transactions at prices that almost correspond to the intrinsic value of the underlying assets. 

This means that investors can effortlessly acquire or exit holdings without experiencing substantial price fluctuations or paying exorbitant trading expenses. Because it affects trading costs and determines how closely the ETF's price matches its underlying assets, an ETF's liquidity is important.

What Is Liquidity?

The concept of liquidity in ETFs goes beyond its traditional application to individual stocks, involving a multi-tiered framework encompassing both the dealer and secondary markets. In the primary or dealer market, liquidity is facilitated through creation and redemption mechanisms. This distinctive process enables adjustments to the ETF's supply to meet investor demand, ensuring price stability. In the secondary market, such as the stock market, liquidity is gauged by the trading volume of the underlying securities in the ETF and their bid-ask spread. A narrower spread often indicates higher liquidity, resulting in lower trading costs.

Liquidity refers to the ease with which an investment can be converted into cash. A highly liquid asset can be swiftly bought and sold in large quantities without significantly impacting its market price. On the other hand, less liquid assets may take longer to sell or may require accepting a discounted price.

Liquidity Measures

The primary indicators of liquidity encompass two key elements:

Trading Volume: The volume of transactions involving an asset is a crucial factor. Higher trading volume generally suggests increased liquidity, as a larger number of buyers and sellers in the market facilitate smoother transactions.

Bid-Ask Spread: The bid-ask spread represents the difference between the highest price a buyer is willing to pay (bid) and the lowest price a seller is willing to accept (ask or offer). A narrower bid-ask spread is often indicative of higher liquidity, as it implies that assets can be bought or sold with minimal impact on the price.

Consider the hypothetical stock of XYZ, Inc. In one scenario, it exhibits both high trading volume and a tight bid-ask spread of $0.02, signifying elevated liquidity. This suggests that shares can be traded easily without significantly affecting the price. Conversely, a stock for ABC, Inc. demonstrates low liquidity with a combination of low trading volume and a wide bid-ask spread of $2.

ETF Primary Market Liquidity

ETFs rely on a special creation and redemption process to supply liquidity to the primary market. ETFs may be created or redeemed by authorized participants (APs), who can also trade the "baskets" containing the underlying equities for fresh ETF shares from the fund issuer.

Since many ETFs are open-ended funds, their ability to adjust the number of outstanding shares is constant. Open-ended ETFs are able to modify their share count in response to changes in supply and demand, in contrast to closed-end funds, which have a predetermined number of shares.

ETF Secondary Market Liquidity

Secondary market liquidity refers to how easily investors can buy or sell ETF shares on exchanges, similar to individual stocks. Key indicators of this liquidity include trading volume, market depth, and the bid-ask spread. Robust liquidity, often indicated by high trading volumes and narrow bid-ask spreads, facilitates more accessible and cost-effective trading for investors.

However, various factors can impact ETF secondary market liquidity. Take, for instance, spot Bitcoin ETFs approved by the U.S. Securities and Exchange Commission on January 10, 2024. While these ETFs initially attracted considerable interest during the initial trading days, the relatively nascent nature of the cryptocurrency market suggests that their liquidity might not be extensive enough. This limitation could hinder traders from easily entering or exiting positions compared to more established ETFs.


Major Players Involved in ETF Liquidity

"Liquidity in the ETF market relies on the collaboration of various key participants, each playing a crucial role. Below are some major contributors to ETF liquidity:

Authorized Participants (APs): At the core of the ETF liquidity mechanism, APs uniquely create and redeem ETF shares directly with the issuer, adjusting the ETF's share supply to meet market demand.

ETF Issuers (Sponsors): Responsible for creating and managing ETFs, issuers oversee the underlying assets. They work alongside APs to ensure ETFs remain liquid and trade in alignment with their Net Asset Value (NAV).

Market Makers: Contributing to ETF liquidity, market makers continuously offer to buy and sell ETF shares at publicly quoted prices, narrowing the bid-ask spread and enhancing liquidity.

Exchanges: Serving as the trading platform for ETF shares, exchanges' operational efficiency impacts the ease of trade execution. ETFs listed on major exchanges are more accessible to a broader range of investors.

Investors and Traders: Both institutional and retail investors contribute to ETF liquidity through their trading activities, influencing trading volumes that subsequently impact liquidity.

Brokers and Dealers: Enabling ETF share trading on behalf of investors, brokers and dealers' understanding of market dynamics and efficient trade execution can influence ETF liquidity.

Custodian Banks: Holding ETF assets on behalf of issuers, custodian banks handle trade settlement and perform operational duties crucial for maintaining ETF functionality and supporting liquidity.

Clearing Houses: Ensuring timely and correct trade settlements, clearing houses play a vital role in maintaining trust and liquidity in the ETF market.


Conclusion

The liquidity of Exchange-Traded Funds (ETFs) is contingent on the dynamics within both the dealer and secondary markets. Authorized Participants (APs), functioning as dealers, have the ability to create and redeem ETF shares, aligning with shifts in supply and demand to maintain the ETF's market price in accordance with its Net Asset Value (NAV). In the secondary market, ETF shares characterized by higher trading volumes and narrower spreads generally exhibit greater liquidity.

Just like any financial instrument, the level of liquidity varies among ETFs. Factors influencing an ETF's liquidity encompass the composition of its underlying securities, the trading volumes of these securities, the ETF's own trading volume, and the prevailing investment climate. It is crucial to comprehend how these elements impact an ETF's liquidity and, consequently, how improvements in its profitability can be achieved, especially in environments where precision in financial outcomes is paramount.
