Peak Margin Rules in India 2026: SEBI Changes and Impact on Intraday Traders
What are Peak Margin Rules?
SEBI introduced Peak Margin rules (fully implemented from September 2021) requiring brokers to report the highest margin used by a client during the day — the ‘peak margin’ — rather than just end-of-day margin. This eliminated the practice of ‘intraday square-off’ leverage where brokers allowed large intraday positions with the expectation of squaring off before 3:20 PM.
How Margin is Now Calculated
| Margin Type | What It Is | When Required |
|---|---|---|
| SPAN Margin | Minimum margin required by exchange for F&O positions | Always — cannot trade without it |
| Exposure Margin | Additional buffer above SPAN (typically 2x SPAN for index, more for stocks) | Always — set by exchange |
| ELM (Extreme Loss Margin) | Additional buffer for extreme market events | Always — especially post-2020 |
| VaR Margin | For equity delivery; Value-at-Risk based | For buying stocks with margin |
| MTM Loss | Mark-to-market loss added to required margin daily | When position is in loss |

Impact on Intraday Traders
Before peak margin rules, brokers could offer 10x–20x intraday leverage. Post peak margin, effective intraday leverage for liquid index futures (Nifty, Bank Nifty) is limited to approximately 3x–4x. For individual stocks in F&O, it varies but is much lower than pre-2021 levels. This has reduced the profitability of scalping strategies that relied on high leverage.
Current Margin Requirements for Common Instruments (2026)
| Instrument | Approx SPAN + Exposure Margin | Maximum Position (per lakh) |
|---|---|---|
| Nifty 50 Futures (1 lot) | ~₹75,000–₹1,00,000 | ~1 lot per ₹1 lakh |
| Bank Nifty Futures (1 lot) | ~₹50,000–₹70,000 | ~1 lot per ₹0.7 lakh |
| Nifty Option Buying | Premium paid only | No margin requirement |
| Nifty Option Selling | ~₹1–1.5 lakh per lot | Very high — exchange mandated |
| Stock Futures (Nifty 50 stocks) | Varies; 15–25% of contract value | Moderate leverage |
