Shares of major capital market players, including BSE Ltd, Angel One, and Groww, witnessed a sharp sell-off today, February 16, 2026, plunging as much as 10% following the Reserve Bank of India’s (RBI) stringent new regulatory framework. The central bank has issued the “Commercial Banks – Credit Facilities Amendment Directions, 2026,” which mandates that all bank lending to capital market intermediaries (CMIs) must be 100% secured by eligible collateral starting April 1, 2026. This move effectively ends the era of partial security and unsecured guarantees, such as those backed only by promoters, forcing brokers to scramble for more expensive alternative funding sources. Markets reacted swiftly to the news, with BSE shares hitting an intraday low of ₹2,736 (down 9.5%), Angel One sliding 6% to ₹2,540, and Groww’s parent firm, Billionbrains Garage Ventures, declining by 5%. Other firms like JM Financial, Motilal Oswal, and MCX also saw significant drops as investors weighed the impact of higher capital requirements on future profitability and trading volumes.
The RBI’s new rules are designed to insulate the banking system from capital market volatility by ensuring that loans to brokers are backed by tangible, liquid assets. Under the revised guidelines, any bank guarantee issued in favor of stock exchanges or clearing corporations must be backed by at least 50% collateral, with 25% of that being held specifically in cash. Furthermore, the central bank has imposed a punishing 40% haircut on equity shares used as collateral, meaning a broker must provide ₹100 worth of shares to secure just ₹60 in funding. Crucially, the RBI has explicitly prohibited banks from financing proprietary trading activities, a move intended to curb speculative excess. While the government recently raised the Securities Transaction Tax (STT) to dampen high-frequency derivatives trading, these new credit curbs add a secondary layer of pressure, particularly on firms heavily reliant on margin trading facilities (MTF) and proprietary desks.
Industry analysts suggest that while these measures strengthen the long-term systemic stability of India’s financial markets, they present an immediate operational challenge for smaller and mid-sized brokerages. The “cash reserve mandate” for margin trading is expected to significantly increase the cost of funds, potentially leading to a consolidation in the broking space as only well-capitalized firms will be able to maintain high-leverage offerings. Experts from JM Financial and Jefferies have noted that companies like Angel One may need to rethink their massive MTF books, while platforms like Groww might need to tap the public markets or issue perpetual bonds to meet the new liquidity requirements. Despite the immediate “knee-jerk” reaction in stock prices, some market veterans argue that this correction could offer a buying opportunity for long-term investors, as the core business of these exchanges and brokers remains tied to India’s structurally growing retail participation, which is expected to adapt to the more robust regulatory environment.
