What Is Margin In Forex Trading?

Margin in forex trading refers to the possibility of borrowing money to allow traders to control larger positions than their actual account balance.

Margin acts as a deposit with the broker, securing a portion of the trader’s funds to cover potential losses. The ratio between the deposit and a maximally allowed position size is also known as leverage. Although lucrative, this ability can be tempting, as Warren Buffett famously said that the three L’s that ruin men are liquor, ladies, and leverage.

A lack of understanding of how margin works can lead to significant losses, so it is essential for traders to grasp the concept thoroughly before engaging in leveraged trades. 

How Margin Works in Forex Trading

Margin refers to the amount of money a trader must deposit to open and maintain a position with the broker. If a trader doesn’t borrow any money from the broker, then the trader is not trading on margin. This approach is typical for long-term investments like buying stocks, where regulation often prevents the use of margin. However, margin trading in forex is a norm, and the ability to control a large position in the market is referred to as leverage.

Leverage is expressed as a ratio, such as 50:1, which means that for every SGD 1 of capital, the trader can control SGD 50 worth of a currency pair. This allows traders to amplify their potential profits, as they can gain exposure to larger market movements than their initial investment would allow. However, leverage also increases the potential for losses, making it a double-edged sword.

Margin and Leverage Example

Consider a trader who wants to open a USD/SGD currency pair position. If the trader’s broker offers a leverage ratio 50:1, the trader could control a $100,000 position with just $2,000 in margin. If the USD/SGD exchange rate moves in the trader’s favor by 1%, the trader will earn a profit of $1,000, a 50% return on their $2,000 margin. Conversely, if the exchange rate moves against the trader by 1%, they would lose $1,000, half their margin deposit.

Different Types of Margin

Depending on the broker and their regulations, there can be two different types of margins for initiating and maintaining a trade.

• Initial Margin: The initial margin, or deposit margin, is the amount of money a trader must deposit with their broker to open a position. This deposit is collateral to cover potential losses and allows the trader to access leverage. The initial margin requirement varies depending on the broker, the currency pair being traded, and the level of leverage being used. For example, if a trader wants to open a position worth $100,000 in the EUR/USD currency pair, and the broker requires a 1% initial margin, the trader would need to deposit $1,000 as collateral.
• Maintenance Margin: Also known as a variation margin, is the minimum amount of equity a trader must maintain in their margin account to keep a position open. If the trader's account equity falls below this level due to adverse market movements, the broker may issue a margin call, requiring the trader to deposit additional funds or close out some or all of their positions to meet the margin requirement.

Understanding Free Margin, Used Margin, and Margin Level

Free margin refers to the amount of money in a trader's account that is available for opening new positions. It is calculated by subtracting the used margin from the account equity. Used margin, on the other hand, is the amount of money that is currently being used as collateral for open positions.

Margin level is an important metric that indicates the health of a trader's margin account. It is calculated by dividing the account equity by the used margin and multiplying the result by 100. A higher margin level indicates a healthier account, while a lower margin level signals that the account is at risk of a margin call.

For example, if a trader has $10,000 in equity and $2,000 in used margin, their margin level would be 500%. If the margin level falls below a certain threshold (usually set by the broker), the trader may receive a margin call or have their positions automatically closed to prevent further losses.

How Brokers Determine Margin Requirements

Brokers determine margin requirements based on several factors, including the trader's account balance, the currency pairs being traded, and the level of market volatility. Higher leverage ratios typically require lower margin deposits, while lower leverage ratios require higher margin deposits.

For example, a broker might require a 1% margin for a major currency pair like EUR/USD but a 2% margin for a more volatile or less liquid pair like USD/SGD.

Additionally, during periods of high market volatility, brokers may increase margin requirements to protect themselves from potential losses. Such notifications often happen after significant market events, such as Brexit, the announcement of the COVID-19 pandemic, and similar.

What is a Margin Call and When it Occurs

A margin call occurs when a trader's account equity falls below the required maintenance margin level. This situation arises when the market moves against the trader's positions, leading to a significant decline in account equity. When a margin call is triggered, the broker may request that the trader deposit additional funds to bring the account equity back up to the required level.

If the trader fails to meet the margin call, the broker may take action to protect their interests, such as liquidating some or all of the trader's open positions. This liquidation is known as a "stop out," and it helps ensure that the trader does not lose more money than they have in their account.

Margin calls can occur en masse in market crashes, particularly in equities markets. However, due to diversified portfolios, sell-off risk can spread to other assets as brokers start liquidating positions, causing a decrease in the value of everything simultaneously. For this reason, simultaneous sell-off events are often called forced deleveraging, as they’re caused by trading using too much margin.

What is a Stop-Out Level?

A stop-out level is the point at which a broker will automatically close a trader's positions to prevent further losses. This level is typically set as a margin level percentage and varies depending on the broker's policies. For example, a broker might set the stop-out level at 50%, meaning that if the trader's margin level falls to 50%, the broker will begin closing positions.

Stop-out levels are designed to protect traders and brokers from excessive losses. For traders, the stop-out level helps ensure that they do not lose more money than they have deposited in their accounts. For brokers, it helps mitigate the risk of having clients with negative account balances.
