HDFC Bank’s net profit for the quarter ended September increased by nearly 5% on year to Rs 19,510 crore. The bank missed the analyst estimate of Rs 19,606 crore as per Bloomberg for the bottom line. Explaining the relatively muted profit growth despite strong business expansion, the management pointed to lower treasury gains compared with the year-ago quarter. “Normalised for the treasury trading gains, you see the year-on-year profit growth is 12.6%,” the management said.
