RBI’s Oil Dollar Window and Forex Curbs: Rupee Defence, Reserve Costs and Hedging Risks

What the RBI has announced

The special window will meet the entire daily dollar requirements of Indian Oil Corporation, Hindustan Petroleum Corporation and Bharat Petroleum Corporation. The RBI will sell US dollars to these public sector OMCs through designated banks from October 12, 2026, until further notice.

Separately, the RBI has tightened rules on cancellation and rebooking, verification of underlying exposures and duplicate hedging. It has also introduced a Foreign Exchange Risk Reserve, or FERR, for specified rupee-linked derivative transactions.

• Cancelled foreign exchange derivative contracts involving INR cannot be rebooked, whether they are deliverable or non-deliverable, when the cancellation occurs after issuance of the Directions.
• Rollover of derivative contracts at maturity remains permitted, subject to existing regulatory provisions.
• The threshold for transactions without establishing the underlying contracted exposure falls from USD 100 million to USD 5 million equivalent across all Authorised Dealers.
• The corresponding threshold for exchange-traded INR currency derivatives also falls to USD 5 million equivalent across recognised stock exchanges taken together.
• Authorised Dealers must retain an undertaking confirming that the same underlying exposure has not been hedged with another Authorised Dealer.

How targeted dollar supply can stabilise the rupee

Oil companies require foreign currency to pay for imports. Routing their daily dollar requirements through an RBI window reduces the need for these large purchases to compete directly with other demand in the ordinary foreign exchange market. It can therefore ease immediate order-flow pressure and reduce disorderly exchange-rate movements.

The facility changes how dollar demand is met; it does not eliminate the oil import bill. To the extent that the RBI supplies dollars from its reserves, the intervention draws on the external buffer. Reserve adequacy and the duration of intervention consequently become important.

Dollar sales against rupees ordinarily absorb rupee liquidity, other things remaining unchanged. This can interact with domestic liquidity management, although the net effect depends on the RBI’s other operations.

• The window targets a concentrated source of structural dollar demand rather than restricting oil imports.
• Its stabilising impact depends on the scale of other demand, capital flows and exchange-rate expectations.
• The official announcement describes a dollar-sale facility; it does not specify an oil-company swap or concessional exchange rate.

FERR and derivative restrictions: discipline versus hedging costs

FERR applies to foreign exchange derivatives involving INR that hedge current account exposures where the user purchases foreign currency against rupees, and whose notional value exceeds USD 2 million equivalent. Authorised Dealers must maintain cash with the RBI equal to 20% of the INR equivalent of each applicable transaction’s notional amount.

This is a cash reserve requirement on the dealer, not a stated 20% tax on the importer. Nevertheless, tying up funds imposes a funding or opportunity cost that dealers may pass on through derivative pricing. It can temper one-sided demand for protection against rupee depreciation, but can also make genuine import hedging more expensive.

Lower verification thresholds and anti-duplication undertakings strengthen the connection between derivatives and real exposures. The trade-off is greater documentation and reduced flexibility, especially when genuine commercial exposures change after a hedge has been cancelled.

• The USD 5 million threshold concerns establishing the underlying exposure; it is not a general prohibition on larger hedges.
• Transactions below the verification threshold are not thereby authorised to lack a genuine underlying contracted exposure.
• FERR is a domestic cash requirement and should not be confused with the RBI’s stock of foreign currency reserves.

Why the package offers breathing space rather than a complete solution

According to the supplied report, the October 7 increase in the repo rate did not prevent renewed rupee weakness. Higher interest rates can support a currency through interest differentials and expectations, but exchange rates also respond to oil prices, foreign investor behaviour and anticipated depreciation.

The Indian Express compares FERR with China’s exchange-rate toolkit. The relevant policy principle is that reserve requirements can change the cost of derivative positions and influence currency-market demand without relying solely on spot intervention or policy rates.

Persistent restrictions can impair price discovery, widen trading spreads or encourage activity to move towards less accessible market segments. The policy test is therefore not merely whether the rupee strengthens immediately, but whether volatility subsides without excessive reserve depletion or damage to legitimate risk management.

• Crude oil prices influence the underlying import-related demand for dollars.
• Foreign capital inflows or outflows can reinforce or offset the benefits of targeted intervention.
• Predictable communication and periodic review are essential to prevent temporary stabilisation tools from becoming lasting market distortions.
