RBI Oil Dollar Window Shields Rupee Near Record Low

An RBI oil dollar window opens on Monday as India's central bank steps up its defence of the rupee. The Reserve Bank of India said on Saturday, October 10, 2026, that it will open a special window to meet "the entire daily dollar requirements" of three state-run oil marketing companies, Indian Oil Corporation, Hindustan Petroleum and Bharat Petroleum, from October 12 until further notice, according to its press release.

What happened

Under the facility, the RBI will sell U.S. dollars to the three companies through designated banks. At the same time, it issued two circulars tightening the rules on foreign exchange derivatives involving the rupee, according to a second release.

The derivative measures are detailed. Banks may no longer let clients rebook rupee-linked derivative contracts that have been cancelled, although rollovers at maturity remain allowed. The threshold for hedging contracted exposures without proving the underlying exposure was cut from $100 million to $5 million, across all banks, with the same cut applied to exchange-traded currency derivatives. Clients must also give an undertaking that the same exposure has not been hedged with another bank. Finally, for contracts with a notional value above $2 million used to hedge current account exposures in which the client buys foreign currency, banks must hold a Foreign Exchange Risk Reserve with the RBI, in cash, equal to 20% of the rupee value of each transaction. The central bank said the steps aim to "strengthen market discipline and ensure appropriate risk management."

Why it matters

The rupee is under heavy pressure. It closed at 96.73 per dollar on October 9, near its record low of 96.96 hit in May, and has fallen more than 7% in calendar 2026, Moneycontrol reported, citing high crude prices, a strong dollar, elevated global bond yields and weak capital flows. Market participants told the outlet the RBI appears keen to keep the currency from breaking the psychologically important 97 level, where further weakness could intensify corporate dollar buying and speculative short positions. Traders have reported stepped-up dollar selling by state-run banks as the rupee moves past 96.80. The currency has also lost around 3.5% so far in the fiscal year that began in April.

The RBI oil dollar window targets one of the biggest sources of dollar demand. Crude oil makes up around 25% of India's imports, Moneycontrol said. Routing the oil companies' daily needs through the RBI could take some demand out of the spot market, although the dollars will come from the central bank's own reserves. "The oil window should help reduce some of the pressure on the spot market," a treasury head at a private bank said, adding that the derivative restrictions could ease forward premiums in the near term. "But the underlying pressures remain."

Dilip Parmar, research analyst at HDFC Securities, said the RBI is trying "to curb excessive volatility and speculative positions," but warned that "banks may pass on the additional hedging costs to customers." The new reserve requirement makes hedging dearer for importers buying dollars forward. The lower threshold "would mainly affect positions not backed by a genuine transaction," the treasury head said, so importers hedging real payment obligations should be less affected. The steps follow the central bank's recent tightening, covered in our report on the RBI rate hike to 5.50%, and come as oil prices stay high, as in our report on Brent at $102.

India has used this tool before. During the 2013 rupee crisis, the RBI opened a special dollar-swap window for oil companies, along with liquidity tightening and a swap facility for deposits from non-resident Indians, Moneycontrol noted.

What's next

The first test comes when markets open on Monday, October 12, the day the window starts. Traders will watch whether the rupee holds below 97, how much reserves fall as the RBI supplies dollars, and whether banks raise hedging charges. The treasury head told Moneycontrol that medium-term depreciation risks would persist, given India's weak balance of payments and its status as a net oil importer.

The RBI oil dollar window has no end date, so its effect on reserves will be a key number to track in weekly data. Analysts quoted by Moneycontrol expect near-term relief rather than a reversal of the trend. This article is for information only and is not investment advice.
