The Catalyst: RBI Tightens Grip on Capital Market Funding
The Reserve Bank of India's (RBI) revised framework, announced on February 13, 2026, fundamentally alters how banks can finance capital market intermediaries. Effective April 1, 2026, the central bank's amendment to the RBI (Commercial Banks – Credit Facilities) Directions prohibits banks from financing intermediaries for acquiring securities for their own trading books, barring specific market-making activities. Furthermore, credit facilities extended to these intermediaries must now be fully collateralized, with a minimum 40% haircut on equity shares used as collateral. This stringent collateral requirement, coupled with stricter terms for bank guarantees, signals a significant regulatory shift aimed at de-risking the banking system. The immediate market reaction on February 16 saw the Nifty Capital Markets index drop by up to 4.3% intraday, with BSE Ltd shares falling nearly 10% to a low of ₹2,726.30, and Angel One Ltd declining by over 4% to ₹2,540.40. Billionbrains Garage Ventures Ltd, the parent of Groww, also saw its share price fall by over 4%.
