When a currency slides to the edge of a cliff, the central bank does not send a press release and hope. It reaches for tools it keeps locked away for exactly these moments. On Saturday, the Reserve Bank of India reached for one of its oldest and most direct instruments: it opened a special dollar window for the country’s three public sector oil companies, a move that takes one of the heaviest buyers of foreign currency out of the open market just as the rupee stares down a record low.

The facility kicks in from Monday, October 12, and will run until further notice. Under it, Indian Oil Corporation, Hindustan Petroleum and Bharat Petroleum will get their daily dollar needs directly from the RBI through designated banks, instead of chasing dollars in the spot market. The central bank also announced tighter rules for foreign exchange derivatives, signalling that it is not just defending the rupee’s level but also the discipline of the market around it.
A currency under siege
To understand why this matters, look at the numbers. The rupee closed at 96.73 to the dollar on Friday, October 9, barely a whisper away from its all-time weakest level of 96.96, touched in May this year. It has fallen more than 7 per cent against the American currency in calendar 2026, a steady slide driven by a punishing combination: crude oil prices above $100 a barrel, relentless foreign portfolio outflows, and a strong dollar fed by elevated US bond yields.
The RBI has been anything but idle. It hiked the repo rate to 5.5 per cent on October 7, the first rate increase since February 2023, and shifted its stance to calibrated tightening. It has intervened regularly in the spot market. Yet the pressure keeps returning. Foreign exchange reserves fell for a fourth consecutive week to $734 billion in the week ended October 2, down from a record $785 billion a month earlier, a decline of roughly $51 billion in four weeks, much of it spent shielding the currency.
Why oil companies matter so much
India imports more than 85 per cent of the crude oil it consumes. Its three state-owned refiners are among the single largest regular buyers of dollars in the country, converting huge sums of rupees into greenbacks every single day to pay for crude shipments. When Brent crude is trading near $106 a barrel, as it was this week, those daily dollar purchases become a torrent.
The special window removes that torrent from the open market. By supplying dollars directly from its reserves, the RBI does two things at once: it eases the downward pressure on the rupee, and it quietly conserves the visible impact of its intervention, since the dollars flow off the books rather than through frantic spot-market buying that can spook traders into a panic. The facility has been used in the past during episodes of currency strain, which is precisely the signal: this is not routine management, this is the contingency playbook.
New rules for the derivatives market
Alongside the dollar window, the RBI rolled out a set of regulatory measures aimed at restoring order in foreign exchange trading. Dealers will no longer be allowed to rebook cancelled rupee-linked foreign exchange derivative contracts. The limit for positions in exchange-traded currency derivatives involving the rupee has been slashed dramatically, from $100 million to $5 million.
Traders also face additional documentation requirements, and the central bank has asked forex dealers to maintain a Foreign Exchange Risk Reserve equal to 20 per cent of the notional amount of every rupee derivative contract. The message is unmistakable: speculative positioning that amplifies the rupee’s fall will face steeper costs and stricter scrutiny.
- The special dollar window: RBI sells dollars directly to Indian Oil, HPCL and BPCL from October 12, until further notice.
- Derivative curbs: Rebooking of cancelled rupee FX contracts barred; position limits cut to $5 million.
- Risk reserve: Dealers must set aside 20 per cent of the notional value of rupee derivative deals.
- Current rate: Rupee at 96.73 per dollar, near the record low of 96.96 set in May.
- Reserves: $734 billion, down about $51 billion from the September 4 peak.
What this means for ordinary Indians
A weak rupee is not an abstract market statistic. It pushes up the cost of imported crude, which feeds into petrol, diesel and cooking gas prices. It makes imported electronics, machinery and raw materials more expensive, and it quietly lifts the broader inflation number the RBI is now fighting with rate hikes. With the central bank already projecting FY27 inflation at 5.2 per cent, a currency that keeps sliding could make that forecast look optimistic.
There is also a psychological line here. If the rupee breaches 97, traders say bearish sentiment could feed on itself, triggering a fresh wave of selling. The RBI’s Governor has argued publicly that the currency may be undervalued at current levels, and Saturday’s measures suggest the bank is determined to prove it, one intervention at a time. In thin Saturday trading, the one-month dollar-rupee contract in the non-deliverable forward market already fell about 40 paise, an early sign the market is listening.
What to watch next
The next few sessions will be the real test. Will the removal of oil-company demand from the spot market be enough to steady the rupee, or will crude prices and global risk sentiment overpower the move? Much also depends on whether foreign investors stop pulling money out of Indian equities and whether the standoff over trade with the United States shows any sign of easing.
For now, the central bank has shown its hand: rate hike on Wednesday, special window on Saturday, and a tighter leash on derivatives traders. The rupee may be under siege, but the RBI has just made clear it intends to hold the line.
Frequently asked questions
What is the RBI’s special dollar window?
It is a facility under which the Reserve Bank sells US dollars directly to Indian Oil, HPCL and BPCL to meet their daily foreign currency needs, instead of letting them buy dollars in the open market. It starts on October 12, 2026, and remains in force until further notice.
Why did the RBI open the dollar window now?
The rupee is hovering near its record low of 96.96 per dollar, weighed down by high crude oil prices, foreign outflows and global risk aversion. The window takes one of the biggest daily sources of dollar demand out of the market, easing pressure on the currency.
How does a weak rupee affect inflation in India?
A weaker rupee makes imports costlier, from crude oil to electronics and machinery. Higher crude prices can push up fuel and transport costs, which feed into food prices and the overall consumer price index.
What are the new RBI rules for forex derivatives?
The central bank has barred rebooking of cancelled rupee FX derivative contracts, cut exchange-traded currency derivative position limits to $5 million, tightened documentation norms, and required a 20 per cent foreign exchange risk reserve on rupee derivative deals.
Will the rupee keep falling from here?
Traders remain cautious. Much will depend on crude oil prices, foreign investor flows and the dollar’s global trend. The RBI’s Saturday measures show it will intervene aggressively to prevent a disorderly fall, but persistent external pressures could still test the 97 level.
The RBI has chosen its weapons. Whether they are enough to turn the rupee’s tide will be decided in the trading sessions to come.
