Circular No. SEBI/HO/MRD/TPD-1/P/CIR/2025/79; Dated: 29.05.2025
The Securities and Exchange Board of India (SEBI) has announced a set of new measures aimed at improving trading convenience and strengthening risk monitoring mechanisms in the equity derivatives segment. These changes reflect SEBI’s continued commitment to fostering a more transparent, efficient, and secure market environment.
1. Key Regulatory Enhancements Introduced
1.1 Delta-Based Open Interest (OI) Calculation
SEBI will now mandate a Delta-Based Open Interest (OI) computation model for derivatives contracts.
- This approach aligns position tracking with actual risk exposure, considering the sensitivity of option prices to underlying movements.
- It offers a more precise method to gauge market positions, particularly in complex options strategies.
1.2 Redefined Market-Wide Position Limits (MWPL)
The Market-Wide Position Limits (MWPL) for index futures and index options are being redefined.
- The aim is to ensure that limits are reflective of market dynamics and index composition.
- This helps avoid concentration risks and supports fair participation across investor classes.
1.3 Trading Restrictions During Ban Periods
New trading restrictions will be enforced during ban periods for specific securities:
- These restrictions are designed to prevent excessive speculative activity.
- They safeguard against potential market manipulation and systemic risks arising from breached limits.
1.4 Eligibility Criteria for Derivatives on Non-Benchmark Indices
SEBI has also set eligibility norms for derivatives contracts based on non-benchmark indices.
- These criteria will assess factors such as liquidity, investor participation, and index robustness.
- The goal is to ensure that only indices with sufficient depth and market relevance are permitted for derivative trading.
2. Objective Behind the Measures
These steps are intended to:
- Improve risk assessment and surveillance
- Enhance market integrity and investor protection
- Foster a more efficient derivatives trading framework
- Align with global best practices in derivatives markets
3. Strengthening Regulatory Oversight
By introducing these measures, SEBI continues to evolve India’s capital markets through:
- Data-driven supervision
- Adaptive risk controls
- Transparent regulatory frameworks
These developments are expected to bolster market confidence and support sustainable growth in the equity derivatives segment.
