Why is higher than usual margin blocked for my F&O trades close to expiry?

If you do not have any F&O trades, higher margins will not be blocked.

The margin blocked for F&O trades can increase:

  1. Four days before expiry (previous week Friday to expiry day) if you have open in-the-money options positions 
  2. One day before expiry (Wednesday & Thursday of expiry week) if you have any open F&O position required to be physically settled or any out-of-the-money short options positions. 
You can check the increased margin requirement on our margin calculator or on the Kite order window as shown below:


Physical settlement means that you will have to give or take actual delivery of the underlying stock. As such, the required margin goes up in proportion to the contract value.
