Margin Call
Margin call is a term commonly used in the financial industry, particularly in trading and investing. It occurs when the value of an investor’s margin account falls below the broker’s required amount, signaling that more funds are needed to cover potential losses. This document provides a detailed exploration of margin calls, their mechanics, importance, and strategies to manage them.
Understanding Margin
What is Margin?
Margin refers to the amount of capital borrowed from a broker to purchase securities. It allows investors to leverage their positions, essentially amplifying potential gains and losses.
How Margin Works
When trading on margin, an investor might put down a percentage of the total trade value, while borrowing the rest. For instance, if the margin requirement is 50%, an investor might put down $10,000 of their own money to buy $20,000 worth of stock, borrowing the remaining $10,000 from their broker.
Margin Call Mechanics
Maintenance Margin
A key aspect of margin trading is the maintenance margin, which is the minimum amount of equity that must be maintained in a margin account. Brokers set this level to ensure that the account retains sufficient value to cover potential losses.
Triggering a Margin Call
A margin call is triggered when the account’s equity falls below the maintenance margin. For example, if an account requires 30% maintenance margin and the account value drops such that the investor’s equity becomes less than 30% of the current value of the positions, a margin call occurs.
Margin Call Example
- Investor borrows $10,000 to buy $20,000 worth of stock.
- The broker’s maintenance margin is 30%.
- If the value of the stock falls to $14,000, the equity in the account is now $4,000 ($14,000 - $10,000).
- The required maintenance margin is 30% of $14,000, which equals $4,200.
- Since $4,000 < $4,200, a margin call is triggered.
Consequences of a Margin Call
Meeting the Margin Call
Upon receiving a margin call, the investor must restore the account balance to the maintenance margin level. This can be done by:
Forced Liquidation
If the investor fails to meet the margin call, the broker has the right to liquidate some or all of the account’s holdings to bring the account back to the required maintenance margin level.
Importance of Margin Calls
Risk Management
Margin calls serve as a risk management tool to protect both the broker and the investor from excessive losses. By requiring additional funds or the liquidation of assets, brokers mitigate the risk of an account going into a negative balance.
Investor Discipline
Margin calls enforce investor discipline by ensuring that positions are not excessively leveraged. They prompt investors to continuously monitor their account balances and the market performance of their securities.
Managing Margin Calls
Regular Monitoring
Investors should regularly monitor their margin account and the performance of their securities. Using financial tools and alerts can help in staying updated.
Margin Cushion
Maintaining a margin cushion—keeping more equity than the minimum required—can help in avoiding margin calls, especially during market volatility.
Diversification
Diversifying assets can spread risk across different investments, reducing the likelihood that a significant drop in one security will trigger a margin call.
Hedging Strategies
Employing hedging strategies, such as options and futures, can help in mitigating potential losses and managing margin requirements effectively.
Real-life Examples
Case of the 2008 Financial Crisis
During the 2008 financial crisis, many investors faced margin calls as the market plummeted. The dramatic drop in asset values triggered widespread margin calls, leading to forced liquidations and further driving down market prices.
Archegos Capital Management
Archegos, a family office managed by Bill Hwang, made headlines in 2021 due to massive margin calls. The firm had highly leveraged positions in various stocks. When those stocks’ prices fell, margin calls from brokers like Credit Suisse and Nomura led to the liquidation of billions in assets.

Conclusion
Margin calls are a critical aspect of margin trading, serving both as a risk management mechanism and a prompt for investor discipline. Understanding the mechanics and managing margin accounts effectively are essential for investors who engage in leveraged trading. Through regular monitoring, maintaining a margin cushion, diversifying investments, and employing hedging strategies, investors can navigate the complexities of margin trading and mitigate the risks associated with margin calls.
