India's banking system deposits reached a historic milestone of ₹284 trillion ($2.99 trillion) by September 2023, according to central bank data reported by The Economic Times. The deposits increased by 21.67 trillion rupees in the first six months of the financial year, with the majority of growth occurring between June and August when the Reserve Bank of India's strategic measures were implemented. As per Moneycontrol, the banking system deposits hit a record high of around 284 trillion rupees in the second half of September, with deposits rising by an aggregate of 20 trillion rupees from June 16 to August 31. Latest data from The Hindu BusinessLine confirms that all scheduled banks reported deposit growth of 9.93% year-on-year in H1 FY26, with year-to-date growth reaching 8.11% compared to 7.42% in the previous year, significantly outpacing the overall economy's growth trajectory.
The primary driver of deposit growth was the discounted swap window introduced by the Reserve Bank of India in June 2023. As reported by The Economic Times, this scheme attracted approximately $133 billion in foreign-currency deposits between June 16 and August 31, significantly boosting the banking system's liquidity position. The deposit window was closed on August 31, a month earlier than originally planned, demonstrating its effectiveness in attracting dollar inflows. According to Moneycontrol, the RBI announced this discounted swap window in June to attract foreign-currency deposits and encouraged lenders to raise cheaper deposits, with the scheme seeing inflows of around $133 billion. Latest reports from The Hindu BusinessLine indicate that forex swap facilities bearing full hedging costs were announced on June 5, 2026, to attract fresh 3-5-year FCNR(B) deposits, with banks successfully mobilizing $133 billion under this mechanism between June 8, 2026 and August 31, 2026.
Banks actively built funding buffers in the fortnight ending September 30, contributing to the overall deposit growth. According to The Economic Times, this period saw inflows of ₹7.73 trillion, helping banks prepare for the quarter's end. As per Moneycontrol, deposits were also boosted by lenders' efforts to build funding buffers before the end of the quarter, with the fortnight ended September 30 seeing inflows of ₹7.73 trillion. The banking system's deposits increased by 8.4% compared to March-end levels, reflecting the combined impact of RBI's scheme and natural deposit growth patterns. Latest data shows that YTD advances growth was lower at 4.17% against 4.60% a year ago, with banks expecting to deploy FCNR(B) deposit proceeds in the next couple of months.
The deposit growth occurred while competition for deposits remained contained, as noted by CareEdge Ratings in their analysis reported by The Economic Times. The October rate hike is expected to rule out further cuts in term deposit rates and may push them up, as banks need to fund credit growth that is outpacing deposit growth while liquidity surplus shrinks. This dynamic suggests continued pressure on deposit mobilization strategies, with the system remaining in surplus during this period. The RBI's latest monetary policy report confirms that credit-deposit gap has narrowed to 81 basis points in the fortnight ended September 15, 2026, from over 89 basis points in the corresponding period last year. The report notes that large interest rate differential in favour of small savings could lead to migration of deposits away from banks, thus widening the credit-deposit gap in the banking system, while transmission to deposit rates further strengthened in H1.
