RBI Tightens Forex Derivative Rules to Ease Pressure on the Rupee: What Changed and Why
On October 10, 2026, the Reserve Bank of India (RBI) issued two circulars that tighten the rules for rupee-linked foreign exchange (forex) derivatives. A derivative here is a contract that fixes the price of dollars for a future date.
Rebooking ban: If a client cancels a rupee derivative contract, banks can no longer let the client book it again. This applies to both deliverable and non-deliverable contracts. Rolling over a contract on its maturity date is still allowed.
Smaller limit without proof: The amount a user can hedge without showing an actual underlying exposure (a real import, export or loan) has been cut from USD 100 million to USD 5 million. Clients hedging a real exposure must also give a written declaration that they have not hedged the same exposure with another bank.
New Foreign Exchange Risk Reserve (FERR): For contracts above USD 2 million that hedge current account deals and involve buying foreign currency against the rupee, banks must keep 20% of the rupee value as cash with the RBI until the contract ends.
Separately, from October 12, 2026, the RBI will sell dollars directly (through designated banks) to the three public sector oil marketing companies: IOC, BPCL and HPCL. This takes their large daily dollar demand out of the open market.
The RBI said the steps would strengthen market discipline, improve risk management and keep the forex market orderly. The rupee closed at 96.73 per dollar on October 9, close to its record closing low of 96.82, and has fallen nearly 7% in 2026 amid foreign capital outflows, high crude oil prices and strong dollar demand.
Exchange Rate Management in India: RBI's Managed Float
India follows a managed float. This means the rupee's value against the dollar is mostly decided by the market, through the daily demand for and supply of dollars. But the RBI does not stay away. When the rupee moves too sharply in either direction, the RBI steps in to smooth the movement. It does not try to fix the rupee at one particular level.
The new rules are a classic managed-float action. The RBI is not fixing the rupee's price. Instead, it is cutting speculative dollar demand and supplying dollars to oil companies directly, so that the market rate moves in a calmer, more orderly way.
Currency Hedging and the Forward Premium
Currency hedging means protecting yourself against a sudden change in the exchange rate. An importer who must pay dollars after three months can sign a forward contract today and lock in the rate. If the rupee falls in the meantime, the importer is safe. The extra amount paid to buy dollars for a future date, compared with today's rate, is called the forward premium, and it is the main cost of hedging.
The RBI's new rules aim at one thing: making sure derivative contracts are used for genuine hedging, not speculation. By shrinking the "no-proof" limit and banning rebooking, the RBI makes it harder to bet against the rupee while still allowing real importers and exporters to protect themselves.
Non-Deliverable Forward (NDF) Market and Offshore Rupee Trading
A Non-Deliverable Forward (NDF) is a contract on the future value of a currency where the currency itself is never exchanged. On the end date, the two sides only pay each other the difference between the agreed rate and the actual rate, usually in US dollars. Rupee NDFs are traded mostly outside India, in centres such as Singapore, Hong Kong, London, Dubai and New York. Because this offshore market is outside the RBI's direct control, big moves there can spill into the rupee's price in India.
Pressure on the rupee often builds through derivative trades, onshore and offshore. By covering non-deliverable contracts in its rebooking ban, the RBI is trying to close routes through which speculative bets against the rupee can keep being rolled and repeated.
