Indian banks reported a 62% decline in treasury income during the September quarter as government bond yields hit 7.19%. While mark-to-market losses on investment portfolios weighed on earnings, major lenders like SBI and HDFC Bank offset the impact through strong loan growth and one-time gains. Investors may watch how ongoing bond yield volatility affects bank margins in the upcoming December quarter.
The Indian banking sector faced significant pressure on treasury earnings in the September 2026 quarter (Q2 FY27) due to a sharp rise in government bond yields. The benchmark 10-year government bond yield rose to approximately 7.19% by the end of September. Because bond prices move in the opposite direction of yields, this increase caused the value of banks' fixed-income securities to fall, forcing lenders to book mark-to-market (MTM) losses on their investment portfolios.
Data indicates that the average treasury income for Indian banks fell by 62% year-on-year. While the impact was widespread, the overall profitability of major lenders remained resilient due to strong performance in their core business operations, such as loan growth and net interest income, alongside one-time strategic gains.
State Bank of India reported a standalone net profit of ₹23,038 crore, representing a 14.28% year-on-year increase. However, this figure included a ₹7,288 crore one-time gain from a stake sale in SBI Funds Management, which helped mask the ₹1,300 crore in MTM losses booked on its treasury portfolio. Similarly, HDFC Bank posted a standalone net profit of ₹19,510 crore, a 4.7% rise year-on-year, even as its treasury trading gains suffered a 67% decline during the quarter.
Beyond the direct impact of bond prices, bank treasuries are finding it difficult to generate alternative income. Recent regulatory restrictions on rupee derivatives and stringent risk-mitigation requirements have reduced the flexibility of trading desks to generate profits through currency or derivative markets. This environment has left many banks with limited options to cushion the impact of rising yields.
The outlook for the December quarter remains cautious. Market participants are monitoring the bond market for signs of stabilization, but persistent yield volatility continues to pose risks to bank margins. Factors such as fluctuating crude oil prices, inflation, and global interest rate trends could keep yields elevated, potentially leading to further portfolio revaluation pressure in the coming months.
Investors may track management commentary in the next quarterly earnings reports for insights on how banks are restructuring their investment portfolios to navigate this interest rate environment. The ability of lenders to maintain core operating margins while managing treasury drag will be a key focus area for the banking sector heading into the end of the financial year.
