IndusInd Bank's stock plummeted 15% after the lender reported a significant drop in net profits for the second quarter due to stress in the microfinance sector and increased provisions for bad loans. The bank's management highlighted the growing strain on microfinance loans, which make up 9% of their loan book, particularly in tier-2 and tier-3 cities. With the overall gross non-performing asset ratio also on the rise, investors are cautious about the bank's future performance.
