S&P Global Ratings warned that RBI's recent regulatory action on Kotak Mahindra Bank could limit the bank's credit growth and profitability. The RBI prohibited Kotak Mahindra Bank from issuing new credit cards and onboarding customers online, impacting a key growth segment. S&P noted the bank may need to rely more on physical branch expansion, increasing operating costs. However, the impact on the bank's credit rating is expected to be minimal, as credit cards constitute a small portion of its total loans. S&P anticipates that Kotak Mahindra Bank may need around a year to address the RBI's concerns related to system stability and disaster recovery.
