The Reserve Bank of India unveiled a package of rupee defense measures over the weekend, shifting state-owned oil companies' daily foreign exchange demand of up to US$250 million to US$400 million directly onto the central bank's balance sheet, while simultaneously reactivating derivative control tools used during the April crisis.

The RBI opened a special window starting October 12, 2026, to provide foreign exchange directly through designated banks to three state-owned refiners — Indian Oil Corporation (IOC), Hindustan Petroleum Corporation (HPCL), and Bharat Petroleum Corporation (BPCL) — completely bypassing the spot market.

According to a report titled "India: RBI Reinforces Rupee Defense" by Goldman Sachs emerging market strategists Rishi Radia and Lu Sun, the above measures could push the rupee higher by 1% to 2% in the short term, but do not address the fundamental problem of insufficient dollar inflows.

Goldman Sachs believes this means the largest buyer of dollars that had been suppressing the rupee in the market on a daily basis has now disappeared from the spot market. Goldman estimates that at current oil prices of around US$100 per barrel, the three refiners' annual dollar demand amounts to approximately US$120 billion.

The Goldman Sachs report states bluntly:

However, the actual demand for dollars has not changed — it has merely shifted to being satisfied through the RBI's foreign exchange reserves.

In other words, pressure on the rupee in the spot market has been alleviated, but at the cost of accelerated reserve depletion. As long as oil prices remain near US$100, every barrel of crude oil India imports will directly consume foreign exchange reserves.

Meanwhile, the RBI has also revived a combination of derivative controls briefly used during the acute stress period in April, including prohibiting the rebooking of cancelled rupee foreign exchange derivative contracts, slashing the cap on foreign exchange derivative positions that can be established without prior proof of actual exposure from US$100 million to US$5 million, and imposing a 20% cash margin deposit requirement on foreign exchange hedging contracts exceeding US$2 million.

Goldman Sachs warns that the overall impact of these measures on capital markets remains uncertain, and the structural pressures facing the rupee have not yet been eliminated.

April Crisis Toolbox Reactivated, Controls Comprehensively Escalated

The other three measures announced over the weekend all point to the same objective — compressing the space for speculative foreign exchange purchases by market participants.

The RBI has reinstated the prohibition on rebooking cancelled rupee foreign exchange derivative contracts. Goldman Sachs notes that this measure is "not a new initiative," having first been introduced on April 1, 2026, during a period of acute rupee pressure, but was withdrawn on April 20 after lasting only 19 days, and has now made a comeback.

Simultaneously introduced is a far more aggressive reduction in position limits: the cap on foreign exchange derivative positions that can be held without pre-establishing actual exposure has been drastically compressed from US$100 million to US$5 million — a reduction of 95% — applicable to all authorized dealers and major foreign exchange derivative exchanges.

The RBI has also required signed undertakings to prevent the same exposure from being hedged multiple times through different authorized dealers.

Additionally, the RBI has established a new Foreign Exchange Risk Provision (FERR) mechanism, stipulating that authorized dealers must deposit cash with the RBI amounting to 20% of the rupee notional value for foreign exchange purchase derivative contracts involving current account transactions with a notional contract value exceeding US$2 million, and must maintain this throughout the contract's duration. Goldman Sachs characterizes this as "a disguised increase in the cost of foreign exchange hedging."

The Goldman Sachs report specifically highlights one obvious loophole in these controls. Offshore independent banks that are not RBI-authorized dealers are not directly bound by the above requirements, as they provide rupee non-deliverable forwards (NDFs), and Goldman Sachs expects that "some hedging demand may flow to the NDF market as a result."

The tightening of the onshore market means hedging activity may accelerate its migration to offshore markets where the RBI's reach is relatively limited.

Short-Term Squeeze Possible, Structural Pressures Persist

From a market positioning perspective, Goldman Sachs believes the market overall currently holds long dollar-rupee positions, and the above measures could trigger a 1% to 2% short-term appreciation of the rupee, with forward points also expected to decline noticeably in the near term.

But Goldman Sachs simultaneously warns that these measures "do not address the fundamental problem of insufficient dollar inflows, and the RBI may ultimately still need to raise real interest rates to attract capital inflows, at which point forward points could rise again."

Against this backdrop, Goldman Sachs' trading recommendations are: buy overnight index swaps (OIS) on dips, and hold long rupee positions against the Philippine peso.

On the macro front, the RBI has recently raised rates by 25 basis points to 5.50% under a "gradual tightening" stance, foreign investors have net sold approximately US$31 billion in Indian equities year-to-date, while domestic institutions have net bought approximately US$72 billion.

Goldman Sachs economist Santanu Sengupta expects the RBI to raise rates by another 25 basis points in December, and by a cumulative additional 50 basis points in the first half of 2027, pushing the policy rate up to 6.25%.

The rupee had previously approached a historic low of 96.8, and Goldman Sachs had earlier noted that India's Nifty index recorded a nine-consecutive-week decline — a streak comparable to the dot-com bubble era.

Whether the package of control measures can reverse the trend will be further tested by the liquidity drain from the October 13 open market operation sales and the October 20 tax payment obligations.
