Indian banks face pressure on net interest margins (NIMs) in Q1 FY27 as deposit growth fails to keep pace with strong credit demand. To bridge this funding gap, lenders are increasingly relying on costlier wholesale funding, such as certificates of deposit, which is expected to weigh on profitability for the quarter.
Indian banks are entering the first quarter of the 2027 fiscal year with a focus on managing their net interest margins, a key measure of profitability representing the difference between interest earned on loans and interest paid on deposits. While credit demand remains strong, analysts project that these margins will likely stay flat or experience a minor decline of 5 to 10 basis points compared to the previous quarter.
The Funding Gap Challenge
The primary driver behind this margin pressure is the widening gap between loan growth and deposit accumulation. Official data indicates that while bank credit has grown at a robust 17.7% as of mid-June, deposit growth has lagged significantly at 12.2%. This mismatch has forced banks to compete aggressively for funds, leading to a higher reliance on expensive term deposits and bulk funding sources.
The banking system’s credit-to-deposit ratio has climbed to approximately 83.4%, up from 75% in the same period last year. To sustain lending momentum, banks have significantly increased their use of certificates of deposit. Market data shows banks raised over Rs 1.8 lakh crore through these instruments in June alone, a sharp rise from Rs 1.12 lakh crore in May. Furthermore, the cost of these funds has increased, with one-year certificate of deposit yields rising to roughly 7.7%, compared to 6.5% previously.
Impact Across the Banking Sector
Profitability expectations vary across the sector. Private sector lenders like Axis Bank and ICICI Bank may face a steeper margin contraction, estimated by some brokerages at up to eight basis points. Conversely, HDFC Bank is anticipated to see a more modest impact, with a projected contraction of around three basis points. Kotak Mahindra Bank is expected to maintain stability in its margins, while public sector lenders, including State Bank of India and Punjab National Bank, are likely to see margins remain flat or dip by about two basis points. Bank of Baroda may experience a more pronounced decline due to factors like lower interest income from tax refunds.
Asset Quality and Future Outlook
Despite the margin headwinds, the overall asset quality of Indian banks appears to be holding steady. Concerns regarding unsecured retail lending are showing signs of easing, and the microfinance sector is trending toward normalization. Analysts expect that the prudent provisioning buffers built up by many banks in previous quarters will help absorb potential seasonal slippages in crop loans and other retail categories.
Looking ahead, while the Reserve Bank of India has introduced measures to support deposit mobilization, the benefits are expected to materialize only in later quarters. Investors will be monitoring how banks manage their cost of funds, the sustainability of credit growth, and whether any changes in management commentary suggest a shift in lending strategies for the remainder of the fiscal year.
