BSE Bankex Banking Sector Regulatory Filings — July 04, 2026

Gross advances grew 18.8% YoY, the highest among the three banks, signaling aggressive market share capture in a competitive environment. However, this growth is funded by 22.8% YoY growth in term deposits, which will pressure NIMs. [BULLISH on growth, BEARISH on margins]

Average deposits grew 13.3% YoY, outpacing average advances growth of 10.8% YoY, indicating a deliberate strategy to build a liquidity buffer. This conservative approach may protect against deposit volatility but could weigh on near-term profitability. [BULLISH on stability, BEARISH on growth]

Net advances grew 15.1% YoY and 3.2% QoQ, maintaining strong momentum. However, total deposits were nearly flat QoQ (+0.1%), and CASA (EOP) plunged 6.7% QoQ, the worst sequential deposit performance. This signals a severe funding squeeze.

Period-end CASA deposits grew only 9.4% YoY, the slowest category, while time deposits grew 14.3% YoY. This widening gap suggests structural CASA ratio erosion, a multi-quarter headwind for NIMs.

Quarterly average CASA grew 5.1% QoQ, contrasting with a 1.4% QoQ decline in end-balance CASA. This divergence suggests a sharp outflow of CASA in the last few days of the quarter, possibly due to corporate tax outflows or quarter-end window dressing. [BEARISH for stability]

Average CASA grew 13.0% YoY and 2.4% QoQ, showing resilience on a smoothed basis, even as end-balance CASA fell sharply. This indicates that the deposit mix deterioration is a late-quarter phenomenon, possibly seasonal.

Average advances under management grew 10.8% YoY, below the sector average of ~15%, suggesting HDFC is prioritizing margin over market share. This could be a deliberate risk-off strategy in a rising rate environment. [BULLISH on risk management]

Term deposits grew 22.8% YoY and 5.5% QoQ, the fastest among the three, indicating aggressive reliance on bulk deposits. This will likely lead to higher cost of funds and NIM compression of 10-15 bps in Q1 FY27.

End-balance CASA declined 6.7% QoQ, the steepest sequential drop among the three banks. If this trend continues, Kotak's historically strong low-cost deposit franchise could be permanently impaired.

Term deposits (end balance) surged 22.8% YoY and 5.5% QoQ, while CASA deposits declined 1.4% QoQ. This mix shift will increase cost of funds by an estimated 15-20 bps, directly hitting NIMs.

Period-end CASA ratio likely fell to ~32.3% from ~34% a year ago (based on 9.4% CASA growth vs 14.7% total deposit growth). Continued erosion could push the ratio below 30%, a key psychological threshold.

Total deposits (EOP) were virtually flat QoQ (+0.1%), while advances grew 3.2% QoQ. This widening gap forces the bank to rely on wholesale funding or reduce loan growth, both of which are negative for earnings.

None of the three filings reported any insider transactions (buying or selling). In a period of deposit stress, the absence of insider buying could be interpreted as a lack of management conviction in near-term stock performance.

None of the filings provided any forward-looking statements on NIMs, loan growth, or deposit strategies. This lack of transparency increases uncertainty and may lead to negative earnings surprises.

The divergence between average CASA (+5.1% QoQ) and end-balance CASA (-1.4% QoQ) suggests unusual quarter-end outflows. If this is a recurring pattern, it signals instability in the deposit base.

At 10.8% YoY, HDFC's advances growth is significantly below Axis (18.8%) and Kotak (15.1%). While this may be prudent, it could lead to market share loss in a growing economy.

With the strongest deposit franchise (₹31,705 Cr in period-end deposits) and a conservative growth strategy, HDFC Bank is best positioned to weather the deposit war. Investors seeking stability in a volatile sector should overweight HDFC.

Axis Bank's 18.8% YoY advances growth is the highest among the three, and its valuation may not fully reflect this momentum. If the bank can stabilize its CASA ratio in subsequent quarters, the stock could re-rate.

Kotak's average CASA grew 13.0% YoY, indicating strong underlying customer relationships. The QoQ end-balance decline may be a one-off event (e.g., large corporate withdrawal). If CASA recovers in Q2, the stock could see a sharp rebound.

The market has already discounted some margin pressure, as bank stocks have underperformed the broader market in recent months. If actual Q1 NIMs come in better than feared, a relief rally is possible.

With a strong capital position and consistent dividend history, HDFC Bank offers a defensive yield. The current deposit growth strategy (outpacing loan growth) suggests management is prioritizing stability, which supports dividend sustainability.

While term deposit growth is a near-term cost headwind, it also builds a sticky, long-term funding base. If interest rates decline in H2 FY27, Axis Bank's large term deposit book will reprice lower, providing a margin tailwind.

Kotak typically trades at a premium to peers. If the stock corrects further on deposit concerns, it could become a compelling buy at a discount to its historical average P/B of ~3.5x.

Q1 FY27 earnings calls (expected mid-July 2026) will provide management commentary on NIM outlook, deposit strategies, and loan growth targets. Positive surprises on CASA recovery could trigger upgrades.

All three banks reported CASA growth lagging term deposit growth, with Kotak showing a 6.7% QoQ decline in end-balance CASA. The sector is experiencing a structural shift to higher-cost deposits, compressing NIMs across the board. Implication: Expect 10-20 bps NIM compression in Q1 FY27 for all three banks.

Axis Bank (18.8% advances growth) is sacrificing margin for market share, while HDFC Bank (10.8% growth) is prioritizing margin stability. Kotak sits in the middle (15.1% growth). This divergence will lead to differentiated earnings outcomes—Axis may report lower NIMs but higher loan loss provisions if growth is risky.

Both Axis and Kotak showed significant divergence between average and end-balance CASA trends. This suggests quarter-end volatility is increasing, possibly due to corporate tax payments, regulatory changes, or competitive poaching. Investors should focus on average balances for a truer picture.

None of the filings announced dividends, buybacks, or capital raises. In a period of deposit stress, the absence of buyback announcements suggests banks are conserving capital for liquidity. This is a defensive posture that may limit upside in the near term.

With no forward-looking statements in any filing, the market is flying blind on management expectations. This increases the importance of the upcoming earnings calls, where any guidance on NIMs or deposit costs will be highly market-moving.

The complete absence of insider transactions in all three filings is notable. In a normal quarter, at least one bank would have reported insider buying. The silence could indicate that management teams are waiting for more clarity on the deposit environment before committing personal capital.

Watch for management commentary on CASA ratio trajectory and whether the bank plans to accelerate loan growth. Date: Expected mid-July 2026.

Monitor whether end-balance CASA recovers in Q2 FY27. A further decline would confirm a structural problem; a rebound would signal a one-off event.

The bank's aggressive term deposit growth will pressure NIMs. Watch for any guidance on NIM floor or cost of funds in the earnings call. Date: Expected mid-July 2026.

The Reserve Bank of India's next monetary policy decision (expected August 2026) will impact deposit and lending rates. A rate cut could relieve margin pressure; a hike would worsen it.

Monitor for any insider buying or selling in the next 30 days. Insider buying by CEOs would be a strong bullish signal; selling would confirm concerns.

If HDFC's CASA ratio drops below 30% (from ~34% last year), it would be a major negative signal for the stock. Watch the next quarterly filing for this metric.

If Kotak's loan-to-deposit ratio exceeds 90% (currently ~89%), the bank may need to raise wholesale funding or slow lending. This is a key risk to monitor.

If the divergence between average and end-balance CASA persists in Q2, it suggests a systemic issue with deposit stickiness. Watch for management explanation in the earnings call.
