Defending the Rupee: A Temporary Buffer Against Imported Inflation

On June 5, the Reserve Bank of India (RBI) announced a slew of measures to attract more dollar inflows into the country. This comes at a time when rising crude oil prices and substantial Foreign Institutional Investor (FII) outflows from Indian equities have pushed the rupee downward to record lows.

These measures include bringing all new issuances of government bonds (15-, 30-, and 40-year) under the Fully Accessible Route (FAR), removing limits of short-term investment and individual securities on foreign investment under the general route, providing tax benefits in the form of capital gains tax exemption on government securities, increasing investment limits for Non-Resident Indians (NRIs) and Overseas Citizens of India (OCIs) in equity instruments traded on stock exchanges without SEBI registration, offering a concessional forex swap facility until September 30 for external commercial borrowings by public sector undertakings, and restoring the time limit for realization of export proceeds to nine months.

One rationale behind the RBI’s measures, along with its direct intervention in the foreign exchange market, is to prevent excessive rupee depreciation and thereby limit imported inflation. India imports roughly 85% of its crude oil requirements, and oil is priced in US dollars. A weaker rupee directly raises the domestic cost of imported fuel, fertilisers, chemicals, and other intermediate inputs, feeding into both the Wholesale Price Index (WPI) and the Consumer Price Index (CPI) inflation. If this pass-through becomes sufficiently large, the next Monetary Policy Committee (MPC) meeting may be compelled to tighten monetary policy to contain inflation expectations.

At its latest meeting, the MPC kept the repo rate unchanged while the RBI lowered its FY27 growth projection to 6.6% from 6.9% and raised its CPI inflation projection for FY27 to 5.1% from 4.6%, citing energy-price risks. The Indian crude basket stood at $98 per barrel on June 4, compared with $106.23 and $114.5 per barrel in May and April, respectively.

On the positive side, despite a sharp rise in global oil prices associated with geopolitical tensions in West Asia, recent data suggest that inflation remains relatively contained. CPI inflation was 3.48% in April 2026, well within the RBI’s target band.

The rupee, however, remains under considerable pressure. It has weakened by more than 6% against the US dollar on a year-to-date basis and is currently trading at around ₹95.78 per dollar. Strong RBI intervention has prevented further weakening.

This intervention, however, has not been costless. India’s foreign exchange reserves have declined from their peak of approximately $728 billion in February 2026 to around $682 billion by the end of May, although the RBI considers this level adequate to provide import cover for about 11 months. RBI data indicate substantial foreign exchange market intervention during the year, including large spot dollar sales and forward purchases.

In effect, the RBI appears to be using the country’s reserve stockpile to cushion households and firms from an external shock. This approach can be sensible when the shock is expected to be temporary. However, if higher oil prices, geopolitical tensions, and capital outflows persist, reserves cannot indefinitely substitute for economic adjustment. Eventually, either the exchange rate must weaken, domestic demand must slow, or interest rates must rise.

The key question, therefore, is not whether India can defend the rupee today—it clearly can, given reserves of roughly $682 billion—but whether the underlying external shock proves temporary or persistent in the months ahead. If the conflict-induced increase in oil prices endures, maintaining an artificially strong rupee will become progressively more expensive, and some combination of exchange-rate adjustment, tighter monetary policy, and slower domestic absorption will ultimately become unavoidable.
