Long-dated contracts margin requirements
Long-dated F&O contracts (far month, next quarter, or longer-dated) typically have higher margin requirements than near-month contracts. The additional margin reflects the greater time-related uncertainty and the wider range of possible outcomes over the longer life of the contract.
Why long-dated needs more margin
For longer-dated contracts:
- Wider price range over the contract life.
- More implied volatility uncertainty.
- More time decay for option sellers (a feature, not a margin issue).
- More liquidity premium / discount risk.
SPAN’s scenario calculations factor in time-to-expiry; longer-dated contracts have larger worst-case loss in some scenarios.
Margin difference by tenor
| Contract tenor | Approximate margin (% of notional) |
|---|---|
| Near month (current) | 10-15% (index futures); higher for stock |
| Next month | Slightly higher (1-3% additional) |
| Far month | 5-10% additional |
| Quarterly long-dated | Even higher |
The exact additional varies by contract, volatility regime, and exchange parameters.
For stock F&O
Stock futures and options long-dated contracts add the pre-expiry physical settlement consideration. For a stock option expiring in 3 months:
- Standard SPAN until 4 days before.
- Pre-expiry margin layer in last 4 days.
For a long-dated stock option, the position-life margin profile differs from the final 4-day spike.
Liquidity in long-dated
Long-dated contracts often have:
- Thinner liquidity (less volume).
- Wider bid-ask spreads.
- Larger execution slippage.
Combined with higher margin, long-dated trading is less efficient capital-wise for short-term moves but better for long-horizon views.
Market orders blocked
Long-dated options often have market orders blocked or restricted on Kite:
- Wide spreads would cause large slippage on market orders.
- Brokers protect retail clients from this by restricting market orders.
For long-dated, use limit orders.

Use cases
Long-dated F&O is appropriate for:
- Long-horizon directional bets (e.g., 6-month view).
- Hedging long stock positions for an extended period.
- Volatility plays where time-decay isn’t a concern.
For most retail intraday / short-cycle trading, near-month is the default.
