The Reserve Bank of India sold $18.2 billion in the first half of October to protect the rupee, marking its largest monthly intervention this year. The move follows heavy selling by foreign investors and rising oil prices. Investors are now watching whether the central bank can maintain this support as foreign exchange reserves drop from their September peak.
The Reserve Bank of India (RBI) offloaded $18.20 billion of its foreign currency reserves between October 1 and 16, 2026, in a significant effort to keep the rupee stable. This is the largest monthly intervention by the central bank so far this year. The move comes as the Indian currency has faced consistent downward pressure due to a combination of rising global crude oil prices, ongoing geopolitical tensions in West Asia, and money flowing out of Indian markets by foreign investors.
Why Currency Pressure Is Building
The rupee has struggled to maintain its ground recently. Two main factors are at play: foreign investors have been pulling capital out of Indian stocks, and the cost of importing oil has risen. These issues have put a strain on the external account, which tracks the money coming in and going out of the country. Previously, certain deposit schemes helped support the currency, but the closing of that window in September has removed a layer of defense, leaving the rupee more sensitive to global changes.
Risks To Future Stability
The central bank’s aggressive selling has led to a noticeable dip in India's total foreign exchange reserves. Data shows that reserves fell to $721.016 billion by the middle of October, down from a peak of $785.706 billion reached in early September. While this amount is still historically high, the rapid decline has started to raise questions about how much more the RBI can spend to defend the rupee if the current global volatility persists.
Another area investors are tracking is the central bank’s forward book. This is essentially a record of future contracts the RBI has entered into to manage the currency. With a net short position of $200.06 billion as of August—much of which is tied to long-term contracts—the RBI faces limits on its flexibility to use these tools to manage market liquidity. The key factor for market participants will be whether the central bank can keep up this pace of intervention if global demand for the US dollar stays strong through the end of the year.
