RBI's New Rules Hammer BSE, Angel One, Groww Shares; Up to 10% Drop

• Shares of capital market and brokerage firms like BSE, Angel One, and Groww plunged up to 10% following new RBI regulations.
• RBI's new rules, effective April 1, 2026, aim to protect the banking system from stock market volatility by altering banks' capital market exposure.
• Banks can now only lend to stockbrokers on a 'fully secured' basis; partial or promoter guarantees are no longer sufficient.
• Proprietary trading by brokers, which accounts for 40% of F&O volume, will no longer be funded by banks, increasing operating costs.
• Experts anticipate increased funding costs for brokers, potential liquidity reduction, and a slowdown in trading activities, especially in the F&O segment.
