FCNR Inflows Ease Liquidity Constraints but Pressure Private Bank Margins
Surging foreign-currency deposits bolster Indian bank liquidity while compressing net interest margins temporarily.
1Liquidity Surge Impacts Margins
Indian private-sector banks experienced a significant influx of foreign-currency non-resident deposits during the September quarter. While this surge bolstered overall liquidity and supported robust credit growth, it simultaneously squeezed net interest margins. Lenders mobilized these funds faster than they could deploy them into loans at standard lending spreads, creating short-term profitability pressure.
2Margin Compression Across Leaders
Major private lenders reported notable margin declines during the July-September period of FY27. ICICI Bank saw its NIM drop to 4.18% from 4.36%, while Axis Bank fell to 3.36% from 3.46%. HDFC Bank also recorded a decrease, reporting a NIM of 3.2% compared to 3.3% in the previous quarter, reflecting industry-wide trends.
3Deployment Challenges and Outlook
Banks are currently working to optimize their asset and liability mix to mitigate these pressures. Executives expect the full impact of FCNR(B) deposits to manifest in the December quarter. Following this period, leadership teams anticipate a recovery in margins as these funds are fully deployed into higher-yielding assets and variable-rate loan portfolios.
4Specific Bank Impact Metrics
ICICI Bank attributed approximately 9-10 basis points of margin pressure to the deposit mix change following $18 billion in FCNR(B) inflows. Similarly, Axis Bank estimated an 11 basis point reduction in NIM due to these deposits. Excluding this specific impact, Axis Bank noted that its core NIM actually improved to 3.47% during the quarter.
5Profitability Amidst Margin Headwinds
Despite the margin compression, major banks reported higher year-on-year net profits for the quarter. HDFC Bank achieved a standalone net profit of ₹19,510 crore, marking a 5% increase. ICICI Bank saw profit growth exceeding 20% to reach ₹14,843 crore, while Axis Bank reported a 38% rise in net profit to ₹7,003 crore.
6Operational Drivers and Growth
Loan growth remained a primary driver for these institutions, with ICICI Bank expanding its portfolio by 30% and Federal Bank crossing the ₹3 trillion mark. Banks are focusing on granularizing their liability franchises and shifting loan mixes. These strategic adjustments are intended to offset the temporary drag caused by the recent foreign-currency deposit mobilization.
7RBL Bank as an Outlier
While most private banks faced margin pressure, RBL Bank emerged as an outlier by reporting an improved NIM of 4.61% for the September quarter, up from 4.13% previously. However, the bank cautioned that margins are likely to remain under pressure in the coming quarter as the full impact of FCNR(B) deposits continues to play out.
8Strategic Path to Recovery
The banking sector expects a non-linear improvement in margins starting from the next quarter. Rising interest rates are anticipated to support this trajectory, as significant portions of balance sheets are linked to variable benchmarks. Banks remain focused on replacing higher-cost deposits and maintaining opex discipline to sustain long-term earnings growth and stability.
