A Margin Call is a demand by a broker or financial institution that a customer deposit enough money or securities to bring a margin account up to the initial margin or minimum maintenance requirements. This usually occurs when the price of securities bought on margin falls, diminishing the account’s equity below the required threshold. If the customer does not meet the margin call, the broker has the right to liquidate assets in the account to cover the shortfall.
Definition and Explanation
A margin call ensures that the customer maintains enough equity in their margin account to cover potential losses. There are typically two types of margin requirements:
- Initial Margin: The percentage of the purchase price of securities that the investor must pay for with their own funds.
- Maintenance Margin: The minimum account balance that must be maintained before a broker will demand additional funds or securities.
In mathematical terms, the maintenance margin can be represented as:
When the account equity falls below this level, a margin call is triggered.
Types of Margin Calls
Initial Margin Call
This is issued when the customer’s available equity falls below the initial margin requirement. For instance, if the initial margin is 50%, and the account equity drops below this percentage, an initial margin call is prompted.
Maintenance Margin Call
A maintenance margin call occurs when the customer’s equity falls below the maintenance margin level. For instance, if the maintenance margin is 25%, and the account equity drops below this threshold due to market fluctuations, the broker will issue a call for additional funds or securities.
Considerations
Risks
- Auto-Liquidation: If the customer fails to meet a margin call, the broker can liquidate assets without the customer’s consent.
- High Volatility: Margin calls can occur frequently in volatile markets, potentially leading to significant financial losses.
Requirements
- Federal Regulations: The Federal Reserve Board regulates margin requirements in the United States under Regulation T, which sets the minimum margin requirements.
- Broker Policies: Individual brokers might have stricter requirements than the federal mandates.
Examples
-
Example 1: An investor buys $10,000 worth of securities with $5,000 of their own money and $5,000 borrowed from a broker. If the value of securities drops to $8,000, and the maintenance margin is 25%, the equity in the account is $3,000 (i.e., $8,000 value - $5,000 loan). Since this is below the required 25% of $8,000 investment ($2,000), a margin call is triggered.
-
Example 2: A trader invests $50,000 in stocks with $30,000 own funds and $20,000 in margin loan. If stocks decline by 40% to $30,000, the equity will be $10,000 ($30,000 - $20,000 loan). If the maintenance margin is 30%, which should be $9,000, the trader needs to deposit additional funds as they are now breaching the maintenance margin.
Historical Context
Margin calls played a significant role during the 1929 stock market crash, exacerbating the sell-off as investors were forced to liquidate assets en masse to meet the demands. Modern regulations and risk management strategies have been developed to prevent similar systemic failures.

Summary
A margin call is a critical mechanism in margin trading that ensures an investor’s margin account maintains sufficient equity relative to the borrowed funds. It serves as a safeguard for brokers and financial institutions, compelling investors to deposit additional funds or securities when the value of their account falls below the specified margin requirements. Understanding how margin calls work, their risks, and how to manage them is essential for any investor engaging in margin trading. Always stay informed about federal regulations and broker policies to navigate margin calls effectively.
