What Is a Liquidity Gap in Finance and Trading

Pavel Satsuk -

Introduction

Liquidity ensures smooth operations in the market, no wonder it is referred to as the lifeblood of financial markets. It refers to the ease with which an asset can be bought or sold without affecting its price. A market that is liquid permits fast and effective deals, which is beneficial to both buyers and sellers. On the other hand, illiquidity can be the reason difficulties arise when an asset is unable to be easily sold for cash or has to be sold at lower prices—resulting in losses.  

For better understanding, we can describe liquidity gaps as a situation when there is imbalance in the number of readily available buyers and sellers, resulting in trades executed at prices that vary from expected price.

Understanding Liquidity Gaps in Finance

A period of diminished trading activity when buyers are not enough to meet seller's demands or vice versa is known as liquidity gap—also called liquidity dry-up or liquidity crunch. Liquidity gaps create an imbalance that makes it very difficult to execute trades at the most frequent market price or near it.

No market is safe from liquidity gaps, bonds, cryptocurrency, forex, stocks, and every market can be easily affected by liquidity gaps if the right trading strategies and efficient risk management techniques are not considered and integrated. In the forex  market, a sudden surge in demand for a currency with limited sellers could create a gap. In the stock market, negative or unpleasant news about a company could result in haste to sell, and if buyers are scarce, it could result in a liquidity gap.

The flash crash of 2010 in the US stock market is an historical example of liquidity gaps, several instances of sharp price swings in particular pairs in the forex market. These events help us better understand this crisis—the possibility of significant disruption when liquidity dries up.

Causes of Liquidity Gaps

A number of factors can lead to the emergence of liquidity gaps. In this section, we will talk about four of the several contributing factors.

  • Market Volatility and Sudden Price Swings:

When there are series of high volatility, rapid price movements is a possible outcome and this could result in a sudden rise in buy or sell orders. And if the market does not take the orders quickly, it could lead to a liquidity gap.

  • Low Trading Volume and Order Book Depth:

Thinly traded markets with low volume and few buy sell orders at diverse prices—or other shallow order books—are susceptible to liquidity gaps. A massive order can easily change the price significantly in markets like this.

  • Economic Events, News, and Central Bank Interventions:

Central bank announcements, economic data news, or geopolitical events are factors that could contribute to liquidity gaps. These factors can create uncertainty in the market and trigger unexpected shifts in market sentiment leading to gaps.

  • Institutional and Algorithmic Trading Impact:

Institutional trades on a large scale and widely circulated algorithmic trading can lead to severe liquidity gaps. Though algorithmic trading increases market efficiency, it can also contribute to sudden price movements and flash crashes if several algorithms react to a certain event

Impact of Liquidity Gaps on Trading

Liquidity gaps have some major impact on trading. Understanding this would help you curb unexpected loss and make trading cost-friendly, We will explain four impact liquidity gaps on trading.

  • Increased Price Slippage and Execution Risk:

When there is a difference in price between the price the trader anticipates and the actual price the trade is executed—liquidity gaps—can increase slippage resulting in unexpected losses.

  • Higher Spreads and Trading Costs:

Spreads—difference between bid and ask price—tend to increase when liquidity is low, resulting in increased cost of trading

  • Market Manipulation and Flash Crashes:

Illiquid markets are vulnerable to manipulation due to the presence of large players, who are capable of influencing price to their advantage. When there is a combination of low liquidity and cascading sell orders, flash crashes—characteristics set off by sudden, unexpected price decline.

  • Effects on Leveraged Trading and Margin Calls:

Traders employing leverage can experience magnified profit or loss. If traders using leverage do not exit their positions at a desired price they can face significant losses in a liquidity gap. There is a possibility of also facing margin calls, when they’ll have to deposit more funds to cover their losses.

How to Manage and Mitigate Liquidity Risk

Managing and mitigating liquidity risk is very important for stakeholders in the market. Important things to look out for when managing and mitigating liquidity risk will be explained in this section, we divided them into two sections, for traders and brokers.

For Traders

Use Limit Orders Instead of Market Orders:

Limit orders determine the maximum price a trader is willing to pay or the minimum price the trader is willing to accept, this helps to lessen the risk of slippage.

Diversify Assets and Avoid Illiquid Markets:

Diversification can help to lessen the impact of liquidity gaps in certain assets. Traders can reduce the exposure to liquidity risk by avoiding illiquid markets.

Monitor Economic Events and News:

Staying updated and keeping up with information in the market is very important for every trader. Traders need to anticipate potential periods of volatility by staying informed about upcoming economic events and news releases and adjust their trading strategies when necessary.

For Brokers

Partnering with Multiple Liquidity Providers:

One advantage of connecting to multiple liquidity providers is the chance to diversify their liquidity sources. This would provide firm and dependable flow of orders even in the time of market stress. However before you settle for this risk management routine as the right one, ensure you evaluate the pros and cons of using multiple liquidity providers for your brokerage firm.

Implementing Risk Management Tools:

The benefits of effectively monitoring market conditions to identify potential liquidity issues cannot be overemphasized. Brokers should implement robust risk management tools to monitor order flow, price volatility, and market depth. This will reduce exposure to liquidity risk.

Offering Advanced Order Execution Strategies:

Brokers can provide traders with access to advanced order types such as iceberg orders—which split large orders into smaller ones to minimize price impact—to help mitigate liquidity risks.
