Why are the margin requirements for futures contracts at Interactive Brokers higher than what is shown on the exchange website?

Interactive Brokers (IBKR) often sets higher margin requirements for futures products compared to the exchange-mandated minimums. This practice is implemented for several important reasons:

1. Risk Management: IBKR considers additional risk scenarios and conducts more extensive scans to account for potential extreme market moves. This approach helps protect both the broker and the clients from unexpected market volatility.
2. Dynamic Adjustments: Margin requirements at IBKR are updated at least twice daily and even more frequently during volatile trading periods. This ensures that the margin requirements reflect current market conditions accurately.

To help traders understand and manage these higher margin requirements, IBKR provides tools to preview the margin impact of new orders or closing positions:

For New Orders:

• In Trader Workstation (TWS):
  1. Right-click on a Buy or Sell order line
  2. Select "Check Margin Impact"
  3. View the projected increase or decrease in the account's total margin requirements if the order were to execute in the "Change" column on the Initial Margin and Maintenance Margin lines.
• In Mosaic:
  1. Create the order in the Order Entry window
  2. Hover over the white arrowhead next to "Submit"
  3. Click on "Check Margin Impact"

For Closing Positions:

•  In Trader Workstation (TWS)/Mosaic:
  1. Right-click on any data line with a position
  2. Go to Contract Info, then click on Show Margin Impact
  3. View the details in the "Change" column on the Initial Margin line

These tools allow traders to anticipate the impact of their trades on their account's margin requirements before executing orders.
