When trading using collateral margins from pledged holdings, you must maintain at least 50% of the total margin requirement in cash or cash-equivalent assets. This complies with SEBI’s regulations and ensures risk management while trading with leverage.
For intraday equity and derivatives, interest is charged at 15% per annum on the portion of margin funded through non-cash collateral or pledged holdings that exceeds the 50% limit.
Margin requirement is determined by the highest margin utilisation during the day, based on exchange snapshots from the NSE F&O segment. This means your intraday peak margin usage is considered while calculating any shortfall or interest.
Under the 50:50 rule, for any given margin requirement:
Example:
You’ll be charged 15% annual interest on the ₹20,000 shortfall (approx. ₹8.22 per day). Interest is calculated daily on the shortfall and debited weekly from your ledger until the cash balance meets the 50% requirement.
| Scenario | Solution |
|---|---|
| I pledged stocks but still got charged interest | Interest applies if your cash or cash-equivalent portion is below 50%, even when you have pledged collateral. |
| I don’t have enough cash to meet the 50% rule | Add funds to bring your cash portion back to 50%; otherwise, interest continues on the shortfall. |
| I unpledged some holdings and then saw interest charged | Unpledging reduces collateral and may drop your cash ratio below 50%, causing fresh interest to apply. |
| How do I avoid recurring interest charges? | Maintain at least 50% of your margin in cash or cash equivalents and monitor it through the Margin Statement. |
