What are Margin Calls

Margin calls are essential part of trading on margin. Trading on margin allows traders to borrow money from their broker to leverage their positions. In this way they can increase their buying power to a considerable extent. However, the increased buying power comes with its disadvantages as well by increasing the risk. Margin calls serve as a safeguard for both the broker and the trader.

When the value of the capital of a trader’s account falls below the specified agreed limit between trader and broker known as maintenance margin level, the margin call triggered. It means that trader either has to deposit more funds in the account or sell a certain level of securities to maintain the margin level. Failing to do so, the broker has the authority to liquidate the trader’s positions to cover his losses.

For example, if a trader has capital of $ 50,000 and the broker has provided the margin of 50% then the trader will have the power to purchase the stock worth of $ 100,000 where broker has provided the loan of $50,000. The option to utilize the borrowed capital also called leverage comes with certain requirements as follow.

Initial Margin: Initial margin is the percentage of minimum investment that a trader should contribute for a trade before taking position.

Maintenance Margin: It is the minimum percentage that trader must maintain in their account to avoid from margin call or to keep his positions open.

Formula for Margin call Example

For example, a trader has opened a trading account by depositing $50,000 in the trading account.

The broker has provided 50% margin which means now he has total $100,000 for buying the stock or equities.

The trader has decided to utilize the full leverage and buy the securities of worth $100,000. So,

Initial purchase price = $100,000

Now let’s assume that trader and broker signed the contract to maintain the minimum 25% maintenance margin to run the account and avoid margin call. So, let’s find out the margin call price with the help of formula for margin call

Margin call price = $100,000 (1 – 50%) / (1 – 25%)

Margin call price = $75,000

So, the account value should always be above $75,000 otherwise trader will receive a margin call.

The maintenance margin is calculated on the basis of market value of the securities and deduct the margin loan. In the above example, if the market value of the securities decline to $75,000 then investor equity will be S 25,000 as

Investor Equity = 75,000 – 50,000

= 25,000

In this case, there will be no margin call as the 25% maintenance level is still maintained.

Let’s continue this example further

Assume the value of securities further decline to $60,000. Now the investor equity will be $10,000 which are less than the 25% maintenance margin which is calculated with the help of formula for margin call.

Investor equity = 60,000 – 50,000 = 10,000

As 10,000/ 60,000 < 25% so margin call will happen in this case. To keep the maintenance level of 25%, the trader has to deposit $5,000 into the account.

As 15,000/60,000 = 25%
