What Is Liquidity and Why Does It Matter?

Published Dec 6, 2018Updated Aug 17, 2023


  • Liquidity is the measure of how easily you can convert an asset into cash or another asset. 

  • It refers to the ease and speed with which assets, such as shares in a company, cryptocurrency, or real estate, can be bought or sold without significant impact on its value, allowing for quick access to cash if needed.

  • When a market is illiquid, it can be very difficult to execute trades without having a significant impact on the price.

Liquidity Definition

Liquidity refers to how easily an asset can be bought or sold without significantly impacting its price. The more liquid an asset, the easier it is to buy or sell, while less liquid assets may take more time and effort to convert into cash.

Both a gold bar and a rare collectible book hold significant value, but their liquidity differs. The gold bar is considered more liquid because it's much easier to find a buyer for gold than it is for rare books. There’s a larger market for buying gold than for the collectible book, and it may take some time to find a buyer willing to pay a fair price for it. You may even have to sell it below its true value.

Liquidity holds crucial importance in the financial world as it determines how easily assets, such as stocks, bonds, or real estate, can be converted into cash. Possessing liquid assets provides the flexibility to promptly access funds for various needs.

Higher liquidity reduces the risk of price manipulation and provides a more accurate representation of an asset’s market value. It also allows traders to enter or exit positions with minimal slippage, which is the difference between an asset’s expected price and the executed price.

For businesses, liquidity is vital for smooth operations. Having sufficient cash or easily convertible assets is necessary to cover expenses, such as salaries and bills. Insufficient liquidity can lead to financial difficulties and challenges in meeting obligations.

Why Is Liquidity Important?

Liquidity is a concept that applies to entities of all sizes, from individuals to large corporations. Its significance can be attributed to several reasons:

1. Facilitates smooth transactions

Liquidity ensures the smooth operation of financial markets by facilitating the quick and hassle-free conversion of assets into cash. For instance, stocks and shares can be bought and sold quickly via online brokerages. This accessibility allows investors to execute transactions promptly, contributing to market efficiency.

2. Fair valuation

Liquidity enhances the price discovery process by enabling a constant flow of trades and information. A liquid market allows buyers and sellers to transact at any time, providing a continuous stream of market data and trades. This information helps participants make informed decisions and ensures that assets are bought and sold at reasonable prices.

3. Market stability

High liquidity levels contribute to price stability by reducing the impact of large buy or sell orders on the asset's value. When there’s a liquid market, even substantial transactions have a minimal effect on prices, minimizing price manipulation and promoting fair market conditions.

4. Personal flexibility

Assets with high liquidity offer greater flexibility and accessibility to investors. They can swiftly convert their holdings into cash or other assets, providing the freedom to respond to changing investment opportunities or unforeseen financial needs.

What Is Liquidity in Crypto?

In the crypto market, liquidity refers to how easily a coin or token can be bought or sold without causing significant price movements. Liquidity is a measure of the availability of buyers and sellers and the ability to execute trades quickly and at fair prices. For example, popular cryptocurrency exchanges have higher trading volumes and more participants, making it easier to buy or sell cryptocurrencies and execute trades.

High-liquidity cryptocurrencies such as bitcoin and ethereum, tend to have a large number of active buyers and sellers. This means there's a greater chance of finding someone to buy or sell your cryptocurrency without significantly affecting its price. This may not be the case for an altcoin with a smaller market capitalization.

Liquidity is influenced by market depth, or order book depth, which refers to the number and size of buy and sell orders in the order book. A deep market implies a substantial number of orders on both the bid (buy) and ask (sell) sides, providing ample liquidity for traders. This allows traders to make larger trades without causing drastic price fluctuations.

Another important concept is the bid-ask spread, which is the difference between the highest price a buyer is willing to pay (bid) and the lowest price a seller is willing to accept (ask). In liquid markets, the spread is generally smaller, meaning that the price difference between buying and selling is narrower. This benefits traders by allowing them to execute crypto trades at more favorable prices.

What is a liquidity pool?

Liquidity pools are a core component of automated market maker (AMM) systems and enable the smooth operation of decentralized exchanges (DEXs). In a liquidity pool, users contribute their assets to create a collective pool of liquidity in exchange for a share of the fees generated from trading activity within the pool. The assets are typically paired and are used to facilitate trading on the platform. Liquidity pools operate by keeping the value derived from multiplying the value of both assets constant.

You can think of it as a reservoir of funds that allows for decentralized, peer-to-peer trading without the need for a centralized intermediary.

What is a crypto liquidity provider?

A crypto liquidity provider (LP) is an individual or entity contributing their crypto assets to a liquidity pool. Liquidity providers play a vital role in decentralized finance (DeFi) platforms by ensuring there’s enough liquidity for traders to buy and sell assets smoothly. By contributing to the liquidity pool, providers increase the availability of assets for trading and help maintain stable prices.

What is liquidity mining in crypto? 

Liquidity mining, or yield farming, plays a critical role in DeFi ecosystems. It involves individuals providing liquidity to a particular or variety of different decentralized applications (DApps) to earn rewards. In doing so, they also help facilitate trades and transactions within that platform.

In exchange for providing liquidity, participants are rewarded with additional tokens. The purpose of providing these rewards is to incentivize people to contribute their assets and help create a liquid market for trading.

What Is Liquidity in Stocks?

Liquidity in the stock market refers to the ease with which a particular stock can be bought or sold in the market without significantly affecting its price. It also measures how quickly and efficiently investors can convert their shares into cash or buy shares without causing significant price fluctuations.

When a stock is considered liquid, it means that there are a sufficient number of buyers and sellers in the market. This high level of trading activity allows investors to enter or exit positions without significant delay or price fluctuation.

Similarly to crypto, liquidity is influenced by several factors, including the number of shares outstanding, trading volume, and the bid-ask spread. A stock with a large number of shares outstanding and a high trading volume is generally more liquid than a stock with fewer shares and less trading activity.

High liquidity ensures that investors can easily buy or sell shares at or near the current market price. It also reduces the risk of not finding a buyer or seller to execute a trade, which can be particularly important for large trades or in volatile market conditions.

Examples of High and Low-Liquidity Assets

Low-liquidity assets

1. Real estate and cars

Direct ownership of real estate and cars can be relatively illiquid, as it can take time and effort to buy or sell them.

2. Art and collectibles

These assets can be highly valuable, but often lack a liquid market, requiring specialized buyers and potentially lengthy sales processes that involve hiring brokers.

3. Private equity

Investments in privately held companies typically have limited liquidity because there is no public market for trading these shares.

High-liquidity assets

1. Shares of public companies

Shares of large companies that trade on the stock exchange tend to be highly liquid due to active trading and broad investor interest.

2. Cash and cash equivalents

Cash refers to physical currency, such as banknotes and coins, and deposits held in readily accessible bank accounts. It’s the most liquid form of investment because it can be used for immediate transactions or easily converted into other assets. Cash equivalents are short-term, highly liquid investments that are readily convertible to cash. Examples include money market funds and Treasury bills.

3. Cryptocurrencies with a high market capitalization

Cryptocurrencies with a high market capitalization are considered highly liquid assets due to the substantial trading volumes and broad market participation they attract, allowing for easier buying and selling without significantly impacting their prices.

What Is Liquidity Risk?

Liquidity risk is the possibility that an asset or security cannot be sold quickly enough or at a fair price due to insufficient market demand. It's the risk of not being able to convert an investment into cash without incurring significant losses or delays.

While liquidity risk for financial institutions arises when there is an imbalance between cash inflows and cash outflows, liquidity risk for businesses refers to the possibility of having insufficient cash or liquid assets to meet short-term financial obligations, such as salaries and loan repayments.

In the DeFi context, liquidity risk refers to the potential for insufficient liquidity or a lack of available funds in a particular DeFi protocol or liquidity pool. This can result in difficulties in executing trades, high slippage, or the inability to withdraw funds from a protocol.

Closing Thoughts

Liquidity plays a critical role in ensuring the smooth functioning of markets and allows investors to buy and sell assets efficiently. High liquidity provides investors with flexibility, a fairer valuation of the asset, and market stability. On the other hand, low liquidity can present challenges and hinder the ease of trading.

Understanding liquidity helps investors assess the ease with which they can enter or exit positions and manage their financial needs. By considering liquidity, investors can make informed decisions and navigate the financial landscape with greater confidence.
