Loan Growth Accelerates
While major banks often capture financial headlines, a group of mid-sized private lenders has quietly posted strong loan growth for the March 2026 quarter. IDFC First Bank led this charge, increasing its loan book by 20.0% year-on-year to ₹2.9 lakh crore. Karur Vysya Bank followed with a 16.9% rise, and South Indian Bank saw its portfolio grow by 15.7%. These figures outpace the 10.2% growth at HDFC Bank and 16.2% at Kotak Mahindra Bank. These regional banks are driving growth mainly through lending to Small and Medium Enterprises (SMEs), retail customers, and via gold-backed loans, using their local reach.
Risk Metrics and Liquidity Tighten
Despite robust asset growth, operational metrics for some mid-sized banks show a more cautious picture. Many are operating with credit-to-deposit (CD) ratios at or above the usual 75-80% benchmark. IDFC First Bank notably hit around 102% in the March 2026 quarter. This means deposits are fully deployed for lending, but liquidity cushions are tighter. Larger banks maintain more conservative ratios: HDFC Bank reported about 98.5% post-merger, Kotak Mahindra Bank 86.5%, and Karur Vysya Bank 85.4%. South Indian Bank's ratio was 82.1%. The system average CD ratio was 83% by mid-March 2026, indicating strong loan demand but also a tightening liquidity environment across the sector.
The Valuation Gap Explained
Faster growth for mid-sized banks is met with a significant valuation discount. Despite expanding loans as much as or more than larger rivals, they trade at much lower multiples. IDFC First Bank, for example, is valued at about 1.1 times its price-to-book value, and Karur Vysya Bank at 2.0 times. South Indian Bank trades below book value at 0.9 times. This is much lower than Kotak Mahindra Bank at 2.9 times and HDFC Bank at 2.2 times book value. P/E multiples also show this gap: South Indian Bank trades at roughly 6.57x, Karur Vysya Bank at 11.3x, and IDFC First Bank at approximately 33.3x trailing earnings as of April 2026. In contrast, HDFC Bank trades at ~17.7x, and Kotak Mahindra Bank at ~30.9x (though some sources cite its P/E near 19.1x). This discount signals that the market is pricing in higher risks for these faster-growing, smaller banks.
Concentrated Risks and Macro Pressures
Market caution likely stems from mid-sized banks' focused business models and their sensitivity to economic shocks. Relying on SME and retail lending fuels growth but also makes them more vulnerable if these sectors weaken. Current geopolitical tensions in the Middle East could impact oil prices and inflation, affecting the Indian economy. SMEs are particularly exposed to supply chain disruptions and slowing demand. Unlike larger, diversified banks with broad deposit bases and varied loan portfolios, these smaller lenders may see a greater impact from economic downturns or specific sector stress. Their high CD ratios, while showing growth, can also indicate less financial flexibility during tight liquidity or rising interest rate periods. History shows banking stocks, including major ones like HDFC Bank, can drop sharply and lose significant value during periods of geopolitical instability.
Outlook Amid Uncertainty
The banking sector's near-term outlook depends on economic uncertainties and geopolitical events. Higher interest rates could boost bank margins, but this may be offset by increased credit costs if economic conditions worsen. Analysts predict private sector banks will show stronger profit growth (~14% YoY) in Q4 FY26 than state-owned banks, with some caution noted for Kotak Mahindra Bank. While hopes of geopolitical de-escalation are driving a market rally, risks remain, such as potential monsoon shortfalls affecting agricultural NPAs or sustained high oil prices. Investors are watching mid-sized banks to see if they can sustain growth while managing higher risk profiles amid changing economic conditions. Analyst sentiment for Karur Vysya Bank is strongly positive, while IDFC First Bank has a more neutral consensus.
