Abstract：India's foreign exchange reserves rose by $8.663 billion in a single week to touch an all-time high of $725.727 billion, according to DD News. For anyone watching the rupee, the number matters because reserves are the cushion the Reserve Bank of India (RBI, the country's central bank) can draw on when it steps into the currency market.
India's foreign exchange reserves rose by $8.663 billion in a single week to touch an all-time high of $725.727 billion, according to DD News. For anyone watching the rupee, the number matters because reserves are the cushion the Reserve Bank of India (RBI, the country's central bank) can draw on when it steps into the currency market.
ContentsWhy a Reserve Buffer Matters for the Rupee
Foreign exchange reserves are assets held by a central bank, mostly in foreign currencies such as the US dollar, along with gold and other holdings. When the rupee comes under selling pressure, the RBI can sell dollars from these reserves to support it. A larger buffer gives the central bank more room to smooth sharp moves in USD/INR, the exchange rate that tells you how many rupees one US dollar buys.
That matters for importers and exporters who price goods in dollars, and for ordinary savers who feel the rupee's swings through imported inflation. It also matters for companies and individuals who hedge (lock in an exchange rate in advance) their future dollar payments or receipts.
How the RBI Built and Then Used Its Dollar Buffer
The reserve build-up has not happened on its own. In a LinkedIn commentary, Naveen Sharma writes that the RBI attracted roughly $143.6 billion in cumulative inflows by 18 September 2026 through special FCNR(B) deposit and foreign-currency borrowing swap schemes. FCNR(B) deposits are foreign currency deposits held with Indian banks, and the scheme offered banks low-cost dollar funding with the RBI bearing the hedging cost on principal, according to the post.
Sharma states that reserves then reached a record $785.7 billion on 4 September. As depreciation pressure intensified, the RBI intervened through dollar sales and USD/INR swaps, and market participants estimated that about $75 billion to $80 billion had been deployed through these operations since 8 June, the post says. By 9 October, reported reserves had fallen to $726.03 billion, a decline of nearly $59.7 billion from the September peak, according to the same commentary.
From 12 October, the RBI opened a dedicated dollar window for three public-sector oil marketing companies, the post states, with the aim of meeting their dollar needs directly and keeping that demand away from the open market. Sharma writes that USD/INR recovered from a record low near 96.96 to close at 94.96 on 16 October.
The Cost Side: Forward Premiums and Liabilities
Sharma points out that the recovery in the spot rate did not immediately ease the forward market. The one-year rupee forward premium, the extra cost of buying dollars for delivery a year later, surged to about 4.5%, its highest level since January 2022, amid severe market illiquidity, according to the post. In plain terms, the rupee can look steadier today while the cost of hedging future dollar needs goes up.
The commentary also flags that the dollars raised through FCNR(B) are liabilities, not free money. Those deposits mature and must be repaid after three to five years, and Sharma notes that the conversion of foreign currency inflows into rupees created surplus liquidity above 10 trillion rupees, prompting the RBI to use liquidity-absorption operations such as VRRR (variable rate reverse repo, a tool that drains cash from the banking system).
Sharma argues that reserves are a buffer rather than an unlimited war chest, and that defending a particular exchange-rate level can progressively draw down usable reserves if dollar demand keeps outpacing supply. The post also notes that India's external debt stood at about $762.8 billion as of March 2026, of which $149.2 billion was short-term, and that the recent foreign-currency mobilisation represents additional liabilities on top of that.
What It Means for USD/INR Watchers
For forex beginners, the practical takeaway is that a record reserve figure is a measure of firepower, not a promise about the rupee's direction. Sharma's commentary stresses that durable rupee strength depends on the real economy, including export competitiveness, deeper integration into global supply chains, stronger manufacturing and an investment climate that attracts global capital. He sums up the distinction as borrowed dollars buying time while earned dollars create lasting strength.
The commentary also notes that a stronger rupee can create headwinds for exporters by reducing their competitiveness and compressing margins in export-oriented sectors. Readers tracking USD/INR should therefore watch both the headline reserve number and the less visible costs in the forward market, where hedging prices can rise even when the spot rate looks calm.
