Understanding Market-Wide Position Limits and Exchange Bans
According to exchange operational guidelines tracked across Business Standard and Moneycontrol, when aggregate open interest across derivative contracts exceeds 95% of the MWPL set for individual underlying assets, exchanges enforce trading restrictions. Traders are prohibited from building fresh long or short positions until open interest unwinds below the 80% threshold across multiple sessions.
Impact on Institutional and Retail Derivative Portfolios
Broking insights compiled by Motilal Oswal and ICICIdirect highlight that securities restricted under F&O bans frequently experience elevated intraday cash market volatility. Arbitrage desks and quantitative funds adjust hedging strategies, redirecting liquidity toward unconstrained constituents within banking, clean energy, and metal sectors.
