India's banking system recorded a deposit surge of approximately ₹7 lakh crore for the fortnight ended 30 June 2026, marking the third-highest fortnightly growth in 29 years, according to a new report by State Bank of India (SBI) Research. The jump signals robust capital flows aided by recent Reserve Bank of India (RBI) and government measures, and points to an upbeat economic start to Q1FY27.

Capital Flows Behind the Surge

After netting out routine quarter-end mobilisation, SBI Research estimates the net jump in capital flows at around $15 billion. The inflows were driven in part by a revival in Foreign Currency Non-Resident (Bank) [FCNR(B)] deposits, External Commercial Borrowings (ECBs), and Overseas Foreign Currency Borrowings (OFCBs).

India has also received $7 billion in foreign institutional investor (FII) inflows since the government announced measures aimed at attracting foreign capital and supporting the rupee. Separately, RBI foreign currency reserves rose by $4.4 billion during the same fortnight, reflecting the central bank's intent to rebuild its forex buffer, the report noted.

Bond Market and Credit Activity

Long-tenor government securities (G-sec) yields rallied faster than corporate bond yields in May and June 2026, supported by foreign inflows and stronger sovereign bond demand. Corporate yields, however, remained sticky amid continued liquidity demand and credit and duration premium requirements from investors.

Three-year AAA-rated bonds saw better demand as issuers shifted partly toward commercial paper, bank loans, and short-tenor funding. Commercial paper issuances climbed in Q1FY27, with June issuances hitting a 55-month high. Incremental bank credit also showed higher growth, reinforcing signs that economic activity has surprised on the upside.

Rupee Movement and Outlook

The rupee appreciated approximately 2.2% from its low of ₹96.8 per US dollar on 20 May 2026 through to June-end. However, recent geopolitical tensions and rising Brent crude prices pushed the currency back down by about 0.4%.

Despite the near-term headwind, the SBI Research report maintains a positive outlook for the Indian rupee. Average crude oil prices for India's import basket are now expected at $80 per barrel or lower, which could translate into savings of at least $30 to $35 billion on the country's annual oil import bill — a significant tailwind for the current account.

What This Means for Q1FY27

The combination of rising deposits, expanding commercial paper issuances, stronger bank credit, and surging FII inflows collectively paint a picture of an economy gaining momentum at the start of the new financial year. Notably, this is the third-highest fortnightly deposit growth India's banking system has recorded in nearly three decades, underscoring the scale of the current capital flow cycle.

Analysts will be watching whether this momentum sustains through Q2FY27, particularly as global crude prices and geopolitical developments remain key variables for the rupee and the broader macroeconomic outlook.
