Summary:
Indian banks reported mixed net interest margins in Q2FY27 as FCNR(B) deposit inflows affected funding costs and lending spreads. The RBI’s October rate hike could influence margins in H2FY27, depending on loan repricing, deposit costs and fund deployment.
Why Are Indian Banks Facing NIM Pressure in Q2FY27?
Indian banks saw mixed net interest margins (NIMs) in Q2FY27 as foreign-currency deposits added liquidity but weighed on lending spreads at several private lenders. Stronger loan books did not automatically translate into wider margins.
The picture may change in H2FY27 following the Reserve Bank of India’s October policy-rate increase. The effect will depend on when loans reprice and how quickly banks deploy recently raised funds.
September Quarter Reveals Uneven Margins
HDFC Bank reported a 3.16% NIM on total assets for the September quarter, down from 3.30% in Q1FY27. Its standalone net interest income rose 9.7% YoY to ₹34,619 crore, while profit reached ₹19,510 crore.
ICICI Bank reported a 4.18% NIM, compared with 4.36% in the preceding quarter. Net interest income increased 17.7% YoY to ₹25,339 crore. Axis Bank recorded a 3.36% NIM and standalone profit of ₹7,003 crore.

Foreign-Currency Funding Comes at a Cost
Foreign Currency Non-Resident (Bank), or FCNR(B)deposits have helped banks mobilise dollar funding. They can support liquidity and credit growth, but the earnings impact depends on currency hedging, funding costs and the yields earned when that money is lent.
Axis Bank reported that its NIM would have been 3.47% excluding the FCNR(B) impact, against the reported 3.36%. ICICI Bank’s deposits grew 27.1% YoY, but growth was 17.0% excluding FCNR(B) deposits. The gap illustrates how foreign-currency inflows changed headline funding growth.
A larger deposit base supports lending capacity, yet money awaiting deployment can earn lower yields than regular loans. Swapping foreign currency into rupees can also carry costs. As those funds move into customer credit, the margin effect may change, subject to demand and loan quality.
Not every lender experienced margin compression. RBL Bank reported a 4.61% NIM, up from 4.13% in Q1FY27. Federal Bank posted 3.32%, broadly unchanged from 3.33%, while Punjab National Bank improved to 2.58% from 2.50%.
RBI Rate Hike Could Change the Next Two Quarters
The RBI increased the repo rate by 25 basis points to 5.50% on October 7, 2026. That decision came after the September quarter ended, so it cannot explain Q2FY27 margin movements.
Higher policy rates can lift yields on external-benchmark floating-rate loans when reset dates arrive. Deposit rates may adjust with a lag, although competition for savings can narrow that benefit. Banks holding surplus FCNR(B) money may also need time to replace lower-yield deployments with regular lending.
What Will Matter in H2FY27
Balance-sheet composition will drive the outcome. Retail and MSME loan growth, the share of low-cost current and savings accounts, deposit repricing and foreign-currency lending will all affect margins.
A uniform rebound is not yet visible in the results. Future quarterly disclosures on NIM, net interest income, deposit costs and the use of FCNR(B) funds will show whether the liquidity gain is translating into sustainable interest earnings.
Impact on the Banking Sector and Bank Stocks
The impact on the banking sector is likely to remain uneven in H2FY27. Private-sector lenders such as HDFC Bank, ICICI Bank and Axis Bank could continue to face margin pressure if foreign-currency funding costs remain elevated or surplus deposits are not deployed into higher-yielding loans. However, the RBI's recent rate hike could support lending yields as floating-rate loans reprice. Public-sector banks, including Punjab National Bank, may benefit from improving margins and lower credit costs, depending on their funding mix. For banking stocks, changes in net interest margins, deposit costs, credit growth and asset quality will remain important factors influencing earnings and investor sentiment.
