RBI Interest Rate Hike Set to Boost Net Interest Margins for Large Indian Banks
The Reserve Bank of India unanimously raised its benchmark repo rate by 25 basis points to 5.5 per cent and moved its policy stance to calibrated tightening. In equity markets, HDFC Bank Limited (NSE:HDFCBANK) rose 2.17 per cent to 707.2 INR following the shift.
The rate increase is expected to expand net interest margins for major lenders by 6 to 10 basis points and lift earnings per share projections by 3 to 5 per cent. Institutions holding higher proportions of repo-linked loans will reprice assets faster than fixed-rate lenders. Mid-sized banks have seen valuation re-ratings of 5 to 25 percentage points calendar-year-to-date, while public sector lenders de-rated by 5 to 25 percentage points, positioning large private banks as attractive relative risk-reward opportunities.
Investors should monitor banking liquidity, which dropped from 11 trillion rupees to 5 trillion rupees, or 2 per cent of net demand and time liabilities. Regulatory actions such as dollar sell-buy swaps, open market operations, and foreign exchange interventions could tighten cash conditions further. A potential cumulative 50 basis point rate increase could push sector earnings growth to a 20 per cent compound annual rate between FY26 and FY28.
