Bank of India and Bank of Baroda led the selloff, tumbling 3% each. Canara Bank dropped 2%, and State Bank of India, the country’s largest lender, slid 1%.
The scale of the pain for public sector banks could be severe. According to Macquarie, PSU banks are likely to see a one-time hit to their net worth in the range of 5% to 10%. The brokerage also flagged that credit costs across PSU lenders could rise by 20 to 25 basis points.
Macquarie identified the new norms as a net positive only for banks with higher home loan exposure, while those sitting on elevated 30–90 days-past-due buckets, particularly in unsecured loans, microfinance, and vehicle finance, along with public sector banks broadly, face the most adverse impact.
Not everyone sees the same magnitude of damage. In a report following the release of draft norms in October, Moody’s projected a more contained impact. “We expect the proposed regulations to reduce the tangible common equity for banks by 50-80 bps,” Moody’s analysts said. “Since the implementation will be phased over four years, allowing banks to avoid a significant day-one reduction of capital, most banks are likely to absorb the decline in capital ratios through more conservative dividend payouts.”
The RBI’s decision Monday to press ahead with the ECL framework dashes expectations that lenders would be granted a more relaxed compliance window. The transition replaces the existing incurred-loss provisioning model, under which banks only book provisions once a loss has effectively occurred, with a forward-looking approach that requires them to build buffers based on anticipated credit losses.
Under the new framework, banks will adopt a “staging framework” for asset classification, requiring higher provisions on stressed loans and using the effective interest rate method. The central bank said the overhaul is intended to strengthen resilience, transparency and consistency across the banking sector.Also read: Coal India rises 3% after Q4.

Crucially, the RBI confirmed it will retain the current 90-day overdue rule for classifying non-performing assets, offering lenders at least that degree of continuity even as the broader provisioning architecture shifts beneath them.
The transition to the new norms is expected to impact banks’ capital adequacy ratios, adding urgency to boardroom conversations about dividend policy, capital planning, and loan book composition heading into 2027.
