RBI data show that over four successive weeks, India's foreign exchange reserves shed $51.1 billion in total, retreating from the all-time high of $785.71 billion recorded in the week ending 4 September to $734.61 billion by the close of the week ending 2 October 2026. Measured against every four-week interval recorded in the RBI's weekly reserves data going back to its September 1998 launch, no comparable period has produced a steeper drop in dollar-denominated terms than this one.

RBI data published on 9 October 2026 showed that, over the reporting week ending 2 October 2026, the country's foreign exchange reserves contracted by $12.95 billion. Two factors drove the contraction in reserves: a drop in foreign currency assets, which make up the bulk of the total, and a lower reported valuation placed on gold holdings.

Dollar sales and other steps taken by the RBI to relieve pressure on the rupee are among the factors that analysts point to as potential contributors to the drawdown, alongside the effect that shifts in currency values and asset prices have on how reserves are measured and reported. Three factors are understood to be driving the drop in foreign exchange reserves: dollar sales by the Reserve Bank of India to ease pressure on the rupee, shifts in the assessed value of foreign currency holdings, and movements in the price of gold.

When the RBI intervenes by offloading dollars, its foreign currency stockpile contracts, and separate forces — among them swings in exchange rates and movements in gold valuations — shape how the total reserve figure ultimately appears on paper.

Economist Mitali Nikore drew on a straightforward analogy when speaking to a broadcast outlet, describing foreign exchange reserves as functioning in the way a household's dollar savings account would for an entire country. Foreign exchange reserves held by the Reserve Bank of India serve three distinct functions: settling the cost of imported goods, meeting obligations on external borrowing, and keeping the rupee's exchange rate on an even keel.

Over the four weeks covered, India's foreign exchange reserves shed $51.1 billion to land at $734.6 billion — a drawdown without precedent in the RBI's weekly data, which dates to September 1998. Between July and September 2026, the Indian crude basket moved from $82 a barrel up to $116 — a shift in oil costs that represents just one thread in a broader set of factors at play.

Dollar-denominated purchases underpin the RBI's import basket, and elevated oil prices are drawing down those foreign exchange reserves at a faster rate. Overseas investors have withdrawn a net $10.3 billion from Indian equities and debt instruments since April, a movement analysts attribute to tensions in West Asia and a broader shift of capital toward perceived safe-haven assets.

One pipeline that had been supplying dollars on a short-term basis has begun to dry up. Two dedicated swap facilities operated by the RBI — one targeting NRI deposits, the other covering overseas borrowings — drew a combined $143.6 billion through 18 September, with the NRI deposit facility having wound down at the end of August.

On September 4, foreign reserves climbed to $785.7 billion, having added $44.9 billion across a single seven-day stretch — a weekly accumulation that had not been matched in any prior recorded period. The decline in those figures reflects, at least in part, a return from an elevated baseline — the NRI deposit window had only just shut during that period.

At present, the effects remain contained in scope. Foreign exchange reserves held enough to cover roughly 11 months of imports, while a dedicated dollar facility through the central bank was made available to oil marketing companies.

Analysts have noted that, should hostilities continue without resolution, dollar inflows into India through fresh foreign investment alone would fall short of what the economy requires. The budget calls for spending to be brought down.

Rupee-denominated settlement — or payment in the exporting nation's own currency — is an option the RBI already sanctions for a wider share of oil transactions, so long as the seller channels those rupees back into purchases of Indian goods and services. Three avenues identified for examination are the broadening of crude oil procurement across multiple source countries, channelling investment into renewable energy infrastructure, and expanding the services trade — a segment that recorded a surplus of $85.8 billion between April and August.
