Impact of Rupee Volatility on Indian Banks' Margins

Margin pressures for Indian banks are anticipated to escalate as the Reserve Bank of India's (RBI) interventions in local-currency liquidity have been constrained by efforts to curb rupee volatility, a report revealed this Thursday. Fortunately, banks' foreign-currency risks continue to be minimal, according to Fitch Ratings.

Projections indicate that sector margins might fall by 20-30 basis points below the current 3.1 percent forecast for the fiscal year ending March 2027 if elevated funding costs tied to Middle East tensions persist. This will likely diminish operating profit relative to risk-weighted assets by approximately 30-40 basis points, deviating from the anticipated 2.5 percent for FY27.

The liquidity conditions have tightened, with the banking-system surplus reducing to 0.5 percent of deposits by March 2026, exacerbated by currency pressures that have seen the rupee depreciate by 4.5 percent. While rupee volatility's direct effects on Indian banks are minimal due to the system's predominantly local-currency denomination, sustained rupee pressure might restrict the RBI's capacity to ease banking system liquidity.
