Understanding the Meaning of Liquidity and Its Importance in Trading

Liquidity is one of the pillars of market health that is often overlooked by newbie traders. When we talk about the meaning of liquidity, we are actually discussing the ease of converting assets into cash or other assets without drastically shaking their prices. Imagine you have a collection of high-value rare items, but you live on a remote island—it's hard to find the right buyer. Conversely, if you want to buy BTC worth $100 USD on the BTC/USDT pair at a major exchange, the transaction can occur almost instantly with no significant impact on the price. This difference illustrates why liquidity is so crucial.

Liquidity: The Measure of Asset Exchange Speed

In simple terms, liquidity describes how quickly and easily an asset can be bought or sold. High liquidity means that an asset can be traded quickly and easily without causing a large price shift. Conversely, low or poor liquidity creates a situation where selling or buying an asset will trigger a significant price impact.

Cash or cash equivalents are the most liquid assets—easy to convert into other forms. In the crypto world, stablecoins play a similar role. Although they are not yet a global payment standard, stablecoins and digital assets are continuously being adopted, and most of the crypto market volume is generated in the form of stablecoins, making them highly liquid.

On the other hand, real estate, luxury cars, or rare artifacts are less liquid. Finding a buyer who accepts a fair price for physical assets is much more difficult and time-consuming. Tangible assets generally have lower liquidity compared to digital assets because there are additional costs and transaction settlement takes longer. In digital exchanges, transactions are just a transfer of bits—a simple and fast clearing process.

Two Types of Liquidity to Know

Accounting Liquidity

In the context of business and company balance sheets, accounting liquidity refers to a company's ability to pay short-term debts and current liabilities using current assets and cash flow. This term is directly related to the financial health of the organization and is often used by analysts to assess the liquidity position of the company.

Market Liquidity

Market liquidity measures the extent to which the market allows assets to be bought or sold at fair prices—the prices that approach the intrinsic value of the assets. Fair price occurs when the lowest ask (seller's price) approaches the highest bid (buyer's price). The difference between the two is called the bid-ask spread.

Bid-Ask Spread: Key Indicator of Market Liquidity

The bid-ask spread is the difference between the lowest ask price and the highest bid price. A low spread indicates a liquid market with healthy trader activity—price inconsistencies are continuously brought back to equilibrium by market participants.

A large spread usually indicates a less liquid market with a significant difference between buyer and seller prices. Arbitrage traders play an important role here by continuously exploiting small differences in the spread. Their activity benefits the market as a whole by reducing the bid-ask spread, providing better trade execution for other traders. They also ensure that there are no large price differences for the same pair across different exchanges.

Why is Liquidity Critical for Traders?

As a digital asset, crypto should be fairly liquid—but the reality is different. Some crypto assets have much better liquidity than others, depending on trading volume and market efficiency. Bitcoin and Ethereum do not face liquidity issues, but many altcoins encounter significant shortages with volumes of only thousands of dollars per day.

When trading assets with low liquidity, you may not be able to exit positions at target prices, resulting in avoidable losses. This is why traders are advised to focus on assets with higher liquidity.

Slippage: Real Risk in Illiquid Markets

When executing large orders in an illiquid market, you will face slippage—the difference between the expected price and the actual execution price. High slippage occurs because the order book does not have enough orders close to the target price. Use limit orders to avoid this, although the orders may not be fully filled.

Liquidity can also change drastically during a financial crisis. Market players rush out to handle financial bonds and short-term obligations, creating extreme volatility.

Conclusion

Understanding the meaning of liquidity is an important foundation for successful traders. Markets with high liquidity allow you to enter and exit positions relatively easily without excessive price impact. When choosing assets to trade, always prioritize high liquidity to reduce slippage and improve order execution.
