BSE Bankex Banking Sector Regulatory Filings — July 04, 2026
The three BSE BANKEX filings for Q1 FY27 (June 2026 quarter) reveal a sector-wide deposit war, with all three banks—HDFC Bank, Kotak Mahindra Bank, and Axis Bank—reporting a pronounced shift from low-cost CASA deposits to higher-cost term deposits. Average advances growth remains robust across the board (10.8%–18.8% YoY), but the funding mix deterioration is the dominant theme: CASA growth lags overall deposit growth in every case, compressing net interest margins (NIMs) and raising funding costs. Axis Bank leads in loan growth (18.8% YoY) but shows the sharpest CASA decline on an end-balance basis (-1.4% QoQ). Kotak Mahindra Bank's sequential CASA drop of 6.7% QoQ is the most alarming, while HDFC Bank's 9.4% YoY CASA growth is the slowest among its deposit categories. No forward-looking guidance, insider transactions, or capital allocation events (dividends/buybacks) were disclosed in these filings, limiting visibility into management's response. The sector is entering a period of margin compression, and the next catalyst will be the full Q1 earnings calls, where NIM outlook and deposit strategies will be critical.
