India’s weekly index options turnover slumps 36% after Jane Street’s ban, with liquidity drying and volatility remaining low.

• SEBI barred Jane Street for index manipulation, leading to sharp drop in options premium turnover on NSE and BSE.
• Jane Street’s withdrawal hurt liquidity, with no new market-makers filling the gap, analysts warn of prolonged impact.
• Low volatility also dampens trading; Nifty volatility index near one-year low, reducing trader activity and risk appetite.
