What triggers a margin cushion notification and what should I do when I receive one?

A Margin Cushion message is an automated alert sent by Interactive Brokers' (IBKR) system when an account's remaining Margin Cushion and financial status approaches a critical point. Specifically, this notification is triggered when an account's Excess Liquidity as a percentage of the Net Liquidation Value falls below 10%.

Here are key points to understand about Margin Cushion notifications:

  • Purpose: The notification serves as a courtesy reminder for account holders to check their account status and take necessary actions.
  • Responsibility: It is crucial to understand that the account holder is ultimately responsible for ensuring their account does not fall into an Excess Liquidity deficit. The notification is a warning system, not a guarantee of protection against such deficits. 
  • Automated Process: These notifications are sent automatically by the system and do not involve manual intervention from IBKR staff.

When you receive a margin cushion notification:

  1. Immediate Review: You should promptly review your account status to understand the current financial situation.
  2. Take Action: If necessary, take steps to increase your Excess Liquidity. This might involve adding funds to your account, closing out positions, or adjusting your investment strategy.
  3. Understand the Implications: Failing to address a margin deficit could potentially lead to forced liquidation of positions to meet margin requirements.
  4. Ongoing Monitoring: Even after addressing the immediate concern, continue to monitor your account regularly to prevent future margin notifications.
