Bank deposit growth in August reached its highest level in 15 years, contributing to a moderation in the incremental credit-deposit (CD) ratio, according to the Reserve Bank of India's September bulletin. Both credit and deposits sustained strong growth in September, despite some moderation, the central bank said. The comments come after scheduled commercial banks (SCBs) saw their CD ratio climb to 82.2 percent in March 2026, while the incremental CD (I-CD) ratio breached 110 percent in both FY2023 and FY2024. In FY2027, the incremental CD ratio peaked at around 114 percent in May and has declined since then, which could be due to an influx of foreign currency non-resident bank (FCNR-B) deposits, according to the central bank.
