Karur Vysya's profit jump rests on a lending margin management expects to narrow

The Karur Vysya Bank earned ₹788 crore in the September 2026 quarter, 37.3% more than a year earlier. The rise did not come from a recovery or a one-off gain. It came from the plain business of lending at a wider gap over what deposits cost, on a bigger book, in a quarter without large bad-loan charges. That makes it sturdier than it looks, and it also means the profit now depends on the two things management told shareholders to expect less of in the second half: the margin and the pace of loan growth.

Most of the rise in pre-tax profit came from net interest income, what the bank earns on loans and investments minus what it pays depositors and lenders. Calculated from reported interest earned less interest paid, it grew 18.7% from a year earlier, against a year-ago figure that itself held one-off interest from a recovered loan. A smaller line of expenses and provisions supplied the other large piece. Other income, which includes cash recovered from loans already written off, went the other way and fell.

The year-ago quarter explains both the fall in other income and the smaller expense line. Back then a single borrower whose loan had been written off repaid ₹295 crore: ₹139 crore of it was booked as interest income and ₹156 crore as other income, and the bank set aside ₹186 crore against bad loans from two large corporate accounts. By our arithmetic the two together added about ₹109 crore to the year-ago pre-tax profit, and neither recurred last quarter. The reported growth therefore understates how much the bank's ordinary earnings rose, and recoveries now play a much smaller part in the result.

What does carry the result is the margin, and management's guidance has spent the year catching up with it. In May and again in July the bank guided to a full-year net interest margin, net interest income as a share of the assets that earn it, no higher than 3.8%, while the quarter before last came in at 4.26%. The chief executive said the margin held at that level last quarter. In October the guide moved to 4% plus, with a higher return-on-assets guide alongside it. The new numbers describe what the bank already earns; they do not predict more.

The informative part came when an analyst asked whether the margin would now trend down. "Yes, yes, that you can expect, the reasons there are a few," Ramesh Boddu, the chief executive, replied. Over the past year the bank moved its gold-loan book from benchmark-linked to fixed rates at higher levels, and that repricing finished around the start of October. The corporate loans the bank is now booking yield a little over 9%, well below what its gold loans earn. Deposit costs edged up during the quarter, and he expects banks flush with cash to compete on loan pricing. Asked whether the margin could stay where it is, he would commit only to 4% and above.

None of this points to a sharp fall. Last year the bank raised its margin guidance mid-year and finished above even the raised range, at 3.97%, and the new floor sits well under what it has been earning. The easing management describes comes from loan mix and competition; it says nothing about loans going bad.

Loan growth is the second thing set to slow. Advances rose 13.0% in the six months to September. The bank replaced its earlier aim of growing a little faster than the industry with a target of 18% to 20% for the year, and warned that the first half should not be read as a guide to the whole. Read as growth on the March book, the target leaves room for only about 4.4% to 6.2% more in the second half, calculated from the reported advances. Management presents that as a choice: it has kept retail gold-loan rates where they are and says that for now it does not want to give up margin for faster growth, though it may cut rates to keep customers if competition demands.

The quarter's profit came from the bank's core lending rather than from one-offs. The two forces behind it, a wider margin than a year ago and a loan book that grew quickly in the first half, are the same two that management now expects to ease in the second half of the year.
