The Bank reported Profit After Tax of ₹1,045 crore in Q2 FY27, up 196.5% year-on-year. For H1 FY27, Profit After Tax stood at ₹2,120 crore, with Return on Assets at 0.99%. Management Commentary 1. Strong deposit growth: Total deposits grew 25.9% YoY and 11.8% QoQ to reach ₹3,48,583 crore. 2. Healthy CASA: Average CASA ratio remained strong at 48.4% in Q2 FY27. The slight decline from 50.1% was primarily due to the large mobilisation of FCNR(B) deposits during the quarter. 3. Loan growth: Loans and advances, including credit substitutes and FCNR(B)-backed loans, grew 30.1% YoY to ₹3,46,913 crore. Excluding loans secured by FCNR(B) deposits, loan growth was 22.2%, gross of IBPC. 4. Operating leverage: Opex growth has remained lower than income growth by about 500 bps YoY for consecutive quarters. 5. Improving cost-to-income ratio: Incremental cost-to-income ratio was 55% in H1 FY27. The core cost-to-income ratio (excluding trading gains) improved to 70.16% in Q2 FY27 from 70.73% in Q1 FY27. 6. Strong growth in core operating profit: Core operating profit, excluding trading gains, grew 38.5% YoY to ₹2,527 crore in Q2 FY27. 7. Stable asset quality: GNPA stood at 1.32% and Net NPA at 0.40%. Credit cost, as a percentage of average assets, reduced to 1.01%. 8. PAT grew 196.5% YoY to ₹1,045 crore in Q2-FY27, resulting in an ROA of 0.93%. H1 FY27 ROA stood at 0.99%. 9. FCNR(B) mobilisation: During Q2 FY27, the Bank mobilised ₹34,390 crore (approximately US$3.6 billion) of FCNR(B) deposits despite having no branch, subsidiary or representative office outside India. This demonstrates the Bank's digital capabilities and the trust it enjoys among customers. These deposits are largely of 3-to-5-year tenor and provide strong structural liquidity for the coming years. The fully loaded cost of FCNR(B), including PSL benefits, is approximately 1% lower than the cost of raising domestic fixed deposits. FCNR mobilisation should benefit NII, PAT, EPS and RoE, although it is optically NIM-dilutive because the balance sheet expanded by ₹24,885 crore as loans were extended by IBU branch against FCNR(B) deposits. 10. Debut international rating: S&P Global Ratings assigned the Bank an investment-grade long-term rating of 'BBB-'. Commenting on the results, Mr. V. Vaidyanathan, MD and CEO, said, “Our PAT crossed ₹1,000 crore for the second quarter in a row, in both Q1 and Q2 FY27. We are also now internationally rated, with an investment-grade rating from S&P Global Ratings. Our Opex growth has been lower than income growth by about 500 basis points for the second consecutive quarter, demonstrating strong operating leverage. Consequently, our cost-to-income ratio continues to decline, and our ROA is now within touching distance of 1%. Further, raising over ₹34,000 crore of FCNR(B) deposits has been a significant positive for the Bank. It provides us with structural liquidity of 3 to 5 years, which is particularly valuable in a rising interest-rate environment. The fully loaded cost of these deposits, including PSL benefits, is about 1% lower than the cost of raising comparable deposits in the domestic market. Overall, Q2 FY27 was an excellent quarter, and we hope to sustain this momentum.” About the Bank 1.
