IDFC FIRST Bank Q4 FY26: Loans up 20%, CASA near 50%

What stood out in Q4 FY26

IDFC FIRST Bank ended Q4 FY26 with steady balance sheet expansion and signs of improving asset quality, even as reported profit was hit by one-off factors. The bank’s disclosures pointed to broad-based loan growth and a deposit franchise that remained large, but saw some end-of-quarter softness. Management attributed the softer deposit trajectory to a combination of savings rate cuts, tight system liquidity, and the impact of a branch-level fraud incident on sentiment. Separately, weaker treasury performance added to the pressure on profitability for the quarter. The result was a quarter where core operating trends and headline earnings moved in opposite directions. For investors, the print brought deposit momentum and credit costs back into focus for FY27.

Balance sheet growth remained strong

As of March 31, 2026, gross loans and advances including credit substitutes were reported at ₹2,90,278 crore, up 20% year-on-year. In another business update, loans were also cited at ₹2,90,362 crore, indicating the same broad scale of the loan book at quarter end. On the funding side, total deposits were reported at ₹2,94,475 crore, up 16.8% year-on-year. The bank also reported customer deposits excluding certificates of deposits at ₹2,84,453 crore, up 17.3% year-on-year. A separate business update put customer deposits at ₹2,84,327 crore versus ₹2,42,543 crore a year ago, translating to 17.2% year-on-year growth and 0.6% sequential growth. These data points together showed growth continued, though the pace in the March quarter was lower than the bank’s usual 20%-plus deposit growth run rate highlighted by management.

Loan growth was broad-based across key products

The bank described the quarter’s loan expansion as broad-based. In its investor presentation, it highlighted that mortgages, vehicle loans, consumer loans, MSME loans and wholesale loans together contributed 87% of incremental growth. This mix indicates the bank is not relying on a single product line for expansion in a quarter where liquidity conditions were described as tight. The commentary also suggests a continued push across retail and commercial segments simultaneously. While the excerpt did not provide product-wise loan book sizes, it did emphasise that incremental momentum was spread across multiple engines. That matters because broad-based growth can reduce dependence on any one risk pocket.

Deposits, CASA, and what changed during the quarter

CASA deposits were reported at ₹1,46,650 crore, up 24% year-on-year, translating into a CASA ratio of 49.8% at end-March. However, the bank acknowledged that end-of-period CASA dipped sequentially. Management attributed the softness to savings rate cuts, the one-off fraud incident, and tight liquidity through the quarter. In an interview following the Q4 results, CEO V Vaidyanathan said the bank cut deposit rates during the quarter, reducing them from 7% to 6.5%, with some buckets seeing cuts of up to 200 basis points. He indicated that some rate-sensitive balances moved out and that the bank had anticipated a flat quarter when the rate reduction was announced. He also said the bank’s 7-8 million existing customers did not withdraw funds during the period of uncertainty.

One-off fraud expense and treasury losses hit optics

For Q4 FY26, the bank reported profit after tax (PAT) of ₹319 crore, down sequentially. The bank linked the decline largely to an upfront expense related to a fraud incident at a branch and a trading loss in the treasury book. Management commentary elsewhere referenced absorbing the full “Haryana fraud impact,” indicating the incident was treated as a one-time operational shock rather than a structural profitability issue. The bank’s narrative was that core franchise metrics were progressing, but headline profitability was temporarily distorted by these non-recurring or market-linked factors. The excerpt did not quantify the fraud-linked expense or the treasury loss, but it clearly positioned both as key drivers of the sequential PAT decline.

Asset quality indicators improved during the quarter

The bank said the quarter reinforced an improving asset quality trajectory. Gross slippages reduced 15% quarter-on-quarter and net slippages reduced 27% quarter-on-quarter. These movements suggest fewer new problem loans and better net outcomes after recoveries and upgrades during the quarter. While the excerpt did not provide gross NPA or net NPA percentages for FY26, it explicitly stated that GNPA and NNPA were improving. Management also flagged credit costs as a monitoring point, particularly as microfinance stabilises under CGFMU coverage. The bank’s emphasis here was on the direction of travel, rather than absolute ratios.

Why deposit growth slowed and what management expects next

Management described the deposit slowdown in the March quarter as deliberate and temporary, and said it was already reversing. Vaidyanathan said April 2026 data was showing strong deposit momentum. The bank also stated in its presentation that inflows normalized in April 2026 and it expects normalized deposit growth from Q1 FY27. In the same interview, the CEO said the bank expects to return to 20% annual deposit growth in FY27, consistent with seven consecutive years of that performance. The bank’s business update also noted that average customer deposits increased 3.0% sequentially and that deposit growth is expected to strengthen from Q1 FY27 onwards. These statements indicate the bank is placing high weight on restoring deposit velocity after rate actions and quarter-end liquidity pressures.

Market factors and quarter-specific headwinds

The bank listed several headwinds that affected deposit growth during the quarter. These included year-end advance tax outflows, a tight liquidity environment, and news flow about incidents reported during the quarter. It also referenced the prevailing West Asia crisis as part of the broader backdrop. At the product level, the reduction of interest rates on savings accounts by 50 to 200 basis points in key buckets was positioned as a direct contributor to deposit churn from rate-sensitive customers. Despite these pressures, the bank said it opened as many new accounts during March 2026 as in prior months, which it used as a signal of stability in customer acquisition.

Key numbers at a glance

What investors are likely to track into FY27

The bank’s Q4 FY26 disclosures presented two parallel storylines. On one hand, the bank reported 20% loan growth, deposit scaling, a near-50% CASA ratio, and improving slippage trends. On the other, the quarter’s profit was weighed down by a one-off fraud-linked expense and treasury trading losses. The monitoring points identified in the text were deposit momentum after Q4 softness, the pace of operating leverage as the liability franchise scales, and whether credit costs trend lower as microfinance stabilises under CGFMU coverage. The next few quarters, particularly Q1 FY27, are likely to be watched for confirmation of April’s deposit recovery and the normalisation of earnings optics once one-offs fade.

Conclusion

IDFC FIRST Bank’s Q4 FY26 update showed steady balance sheet growth and improving asset-quality indicators, even as near-term profitability was distorted by a fraud incident expense and weaker treasury performance. Management has said deposit inflows normalised in April 2026 and expects deposit growth to normalise from Q1 FY27. The bank’s stated focus areas for the next phase remain restoring deposit momentum after rate cuts, improving operating leverage, and keeping credit costs on a sustainable path as portfolio conditions stabilise.
