Margin Call

A margin call is a broker or clearing demand to add equity, reduce exposure, or face liquidation after margin requirements are not met.

A margin call is a broker or clearing demand to add equity, deposit collateral, reduce exposure, or otherwise bring an account back into compliance after it falls below a margin requirement.

The term can sound like a warning phone call, but in practice the broker may act quickly under the margin agreement. A margin call can lead to trading restrictions or forced sales if the account does not meet the requirement.

Key Takeaways

  • A margin call means the account no longer satisfies an applicable margin requirement.
  • The required action may be a cash deposit, securities deposit, position reduction, or liquidation.
  • A broker may have the right to sell securities without waiting for the investor’s preferred timing.
  • Market gaps, volatility, and illiquidity can make a margin call more costly than expected.
  • A stop-loss order is not the same as margin-call protection.

Example

An investor holds $25,000 of stock financed with a $10,000 margin loan, leaving $15,000 of equity before interest and fees. If the stock falls to $18,000, the loan remains $10,000 and equity falls to $8,000.

If the broker’s current maintenance requirement is higher than the remaining equity, the account can receive a margin call. The investor may need to deposit cash, transfer eligible securities, or sell positions. If the account is not corrected, the broker may liquidate assets.
