Margin Shortfall Penalty
A margin shortfall penalty is a fine levied when a trader fails to maintain the required upfront margin for F&O positions.
Under SEBI rules, if your available margin falls short of the SPAN plus exposure requirement at any peak-margin snapshot, the clearing corporation imposes a penalty — typically a percentage of the shortfall, rising for repeated or large breaches. The broker passes this charge on to the client.
This is why Indian brokers now insist on full upfront margin and may block trades that would create a shortfall. For active F&O traders, even a brief intraday dip below the requirement during a snapshot can trigger the penalty, making margin buffers and pledged collateral important.
