The Significance of Liquidity in Forex Trading

One of the most important components of every financial market, including the FX market, is liquidity. However, what is liquidity precisely, and why is it important to forex traders?

One idea that is essential to financial markets is liquidity. It shows the extent to which an asset’s price can be changed slightly by buying or selling it. Depth must be taken into account in order to comprehend liquidity. A market with a lot of depth can handle huge orders because it contains a wide range of buyers and sellers at different price points.

What Does the Forex Market’s Liquidity Mean?

Liquidity has a similar meaning in the foreign exchange market, commonly known as the forex or FX market; it describes how simple it is to buy or sell a currency pair in real time without affecting its exchange rate. The ability to open and cancel positions at desired prices on a highly liquid forex market might assist traders cut transaction costs.

With an average daily volume of $7.5 trillion, forex is the largest financial market in the world (Bank for International Settlements). This is a result of the numerous participants who trade throughout the day and across time zones; thus, there is nearly always someone ready to buy or sell a currency pair.

A currency pair’s volume and popularity in the market determine how liquid it is. The world’s leading currencies, such as the US dollar (USD), the euro (EUR), the Japanese yen (JPY), the British pound (GBP), and the Swiss franc (CHF), are usually involved in the most liquid pairs. For instance, in 2022, the US dollar made up 88.5% of all daily forex volume. This indicates that pairs that feature the US dollar are frequently quite liquid.

The Currency Market’s Need for Liquidity

Forex liquidity creates favourable trading conditions and economic stability, which are necessary for markets and entire economies to operate correctly.

Tight spreads are typically available in highly liquid markets, allowing trades to be performed around the trader’s desired entry price and with little expense. Transaction expenses have less of an impact on traders’ total profitability when they execute positions often. High liquidity allows huge orders to be executed by entities that trade large volumes at once without significantly impacting exchange rates.

Excessive currency swings can ruin an economy by discouraging investors and upsetting the equilibrium of prices for goods and services. This brings us to the topic of economic stability. Increased liquidity makes the market more stable overall by facilitating seamless price adjustments and more consistent movements.

Market Entities Affecting Forex Liquidity

FX liquidity is supported by a number of market players, including central banks and individual retail traders. Let’s examine a few of them in more detail.

Central Banking Institutions:

Since they determine monetary policy and uphold currency stability for their respective nations, central banks are arguably the most significant players in the foreign exchange market. They might not be as involved as other players, but their actions—like changing interest rates or entering the currency market—can have a big impact on how liquid a particular currency pair is.

Banks that are Commercial:

One may argue that commercial banks are the foundation of the foreign exchange market. As part of their routine banking activities, which also include foreign transactions, client hedging, and proprietary trading, they usually engage in currency trading.

Investors with Institutions:

Significant foreign exchange transactions are an element of the investment strategies of hedge funds, mutual funds, pension funds, and other financial organizations. High-volume trades are frequently made by these firms, increasing FX liquidity.

International Businesses:

These businesses deal with a variety of currencies and operate across borders. Large-scale foreign exchange transactions may arise from their desire to hedge against currency risk, which would increase market liquidity.

Shopkeepers at Retail:

Despite making up only 2.5% of the daily forex turnover (Bank for International Settlements), individual retail traders nevertheless add to the liquidity of the market.

How to Recognize High and Low Liquidity

The foreign exchange market’s liquidity is subject to fluctuations, resulting in periods of elevated and decreased liquidity, each exhibiting unique attributes and trading ramifications.

High Level of Liquidity

Numerous buyers and sellers lead to large trade volumes when there is significant market liquidity. The spread between the ask and bid prices tends to contract during these times, which lowers transaction costs and slippage.

Additionally, strong liquidity encourages market stability by facilitating smaller, more regular price movements. For traders, these can be the ideal market conditions. Because they are widely accepted, major currency pairs like EUR/USD, GBP/USD, and USD/JPY frequently have substantial liquidity.

Insufficient Liquidity:

On the other hand, decreased trading volume and less active traders characterise periods of illiquidity. Wider bid-ask spreads are frequently the result of this environment, which increases the cost of transactions for traders.

Furthermore, price changes may be less predictable and more volatile, which might result in slippage and price gaps. Exotic currency pairings that represent smaller or emerging economies, like EUR/TRY (euro/Turkish lira) or USD/ZAR (US dollar/South African rand), are frequently linked to lower liquidity.

Calculating Liquidity in Forex

It might be challenging to measure liquidity in the forex market since there isn’t just one exchange where all trades take place. However, in order to evaluate the relative liquidity of a currency pair, traders frequently employ a number of indicators.

  • Bid-Ask Spread: One clear sign of liquidity is the bid-ask spread. High liquidity is indicated by a tight spread, and low liquidity is suggested by a broad spread.
  • Volume: In general, high trade volumes are indicative of good liquidity, whereas low volumes are indicative of low liquidity. However, precise volume data can be difficult to collect due to the decentralized nature of the FX market. Therefore, rather than comparing two different pairs, it is preferable to compare a pair’s volume with its historical volume in order to determine relative liquidity.
  • Price Movement: Changes in price also indicate liquidity. Prices fluctuate smoothly in liquid markets without sudden gaps or sharp spikes, but illiquid markets are more likely to be volatile and to create gaps.
  • Market Depth: Certain trading platforms include information on the depth of the order book, which might reveal information on market liquidity. High liquidity is indicated by a deep order book including numerous buy and sell orders at various price points.

Factors Affecting Liquidity

There are a number of variables that can affect liquidity in the forex market. These factors have the potential to alter trade volume and, in turn, particular currency pairings’ liquidity. It’s important to remember that these elements can cause illiquidity in even the most liquid currency markets, such as the EUR/USD pair.

  • Market Timings: The foreign exchange market is open for business five days a week, 24 hours a day, in several time zones. However, during certain hours, liquidity fluctuates. When the two main market sessions coincide—the London and New York sessions, in particular—it usually reaches its peak. On the other hand, liquidity might be rather low during off-peak times, such as the late US or early Asian sessions.
  • News and Events in Economics: Forex liquidity may be significantly impacted by news and events in the economy. Liquidity frequently dries up as traders wait for the outcome in the moments before and immediately following major economic releases, such as job figures, inflation data, or central bank announcements. But after a while, trade volume may increase significantly, which would increase liquidity.
  • Market Sentiment: Traders may be reluctant to enter positions during periods of extreme market volatility or uncertainty, such as during geopolitical crises or economic shocks. Lower liquidity and trading volume may result from this. Conversely, a bullish market sentiment, characterized by traders’ willingness and confidence to trade, can increase market activity and liquidity.

Alerts Indicative of Illiquidity

We can begin to identify some of the warning indicators of illiquidity that may indicate it would be wise to hold off on taking a position until liquidity improves using our understanding of how the forex market’s liquidity functions.

  • Expanding Spreads: A broadening bid-ask spread is one of the most obvious indicators of illiquidity. Wide spreads are frequently noticeable around the close of trading sessions or right before a significant economic announcement.
  • Increased Slippage: When a trade is done at a price that differs from what was anticipated, slippage happens. It’s possible that you are trading in an illiquid market if you find that your orders are consistently filled at prices that are not favorable.
  • Price Differences: Illiquid markets are more prone to experience price gaps, which are instances in which the value of a currency pair abruptly changes without trading at intermediate levels. This is due to the fact that prices may fluctuate dramatically until an order is filled if there are neither buyers nor sellers at a certain price.
  • Increased Volatility: Even in reaction to relatively small trades, illiquid markets may experience bigger price fluctuations. A lack of liquidity may be indicated if you observe significant and unpredictable price swings without a commensurate shift in the underlying variables.
  • Diminished Market Depth: Illiquidity may be indicated by a shallow order book, which is typified by fewer buy and sell orders at various price points. This might be more apparent in unusual or less common currency pairings.

Managing Liquidity in Foreign Exchange Trading

Particularly for novices, comprehending and utilizing liquidity in the forex market can have some major benefits.

Selecting the Appropriate Trading Times: 

As previously mentioned, trading activity and liquidity typically peak during trading session overlap, particularly between the London and New York sessions. Trades at the busiest hours of the day can result in lower slippage and tighter spreads for traders.

Choosing the Right pairings: 

Different currency pairings work well with different trading methods when it comes to liquidity. Major pairings are ideally suited for short-term traders since they are typically more liquid than minor or exotic pairs, such as EUR/USD or USD/JPY. Because they trade less frequently, swing or position traders can be less concerned about liquidity risks.

Risk management: 

A trader’s stop loss can be readily triggered by irregular price changes in less liquid markets. Their take-profit aim is also impacted because a bigger spread results in positions being closed at prices below their ideal value.

Forex Liquidity: Benefits and Dangers

The Benefits of High Liquidity

  • Tight Spreads: Reduced transaction costs associated with tighter spreads are frequently the result of high liquidity.
  • Price Stability: Price action is easier to interpret in liquid markets since there are typically less significant price swings.

Low Liquidity’s Risks

  • Expenses Rising: Certain short-term methods may become infeasible due to increased transaction costs in illiquid markets with wide spreads.
  • Volatility: Without effective risk management procedures, the additional volatility of illiquid markets may raise the chance of losses.
  • Slippage: Insufficient liquidity raises the possibility that an order may be filled at a price lower than anticipated, which would lower profitability and possibly increase losses.
