of each large dollar-buying hedge must sit as cash at the RBI
RBI puts a 20% cash rule on large dollar hedges
On October 10, 2026, the RBI told banks to keep cash equal to 20% of certain large forex derivative contracts with it. The rule applies when customers buy dollars or other foreign currencies using rupees to pay for imports and other current expenses. It applies to contracts worth more than $2 million. Banks must keep this cash with the RBI until the contract ends.
Imagine an importer who needs to pay $10 million 6 months from now. They worry that the rupee could weaken, making those dollars more expensive. So, they sign a forward contract with a bank to lock in the exchange rate today. Under the new rule, the bank must now set aside cash against this contract, making the hedge more expensive to provide.
The rule applies only one way. Importers buying dollars are affected, but exporters selling dollars are not. Hedges linked to loans or investments are also excluded. Neither does the rule apply to contracts signed before October 10, 2026. The RBI is targeting contracts used to lock in the cost of future foreign currency payments.
Here's how the cost adds up. An importer hedging $10 million at ₹96.31 per dollar, the exchange rate on October 2, 2026, has a contract worth ₹96.31 crore. The bank must set aside 20% of this amount, or ₹19.26 crore, with the RBI. The circular does not say whether this cash earns interest. Assuming it earns nothing, the bank loses the chance to earn interest on that money elsewhere. At the repo rate of 5.50%, set on October 7, this works out to roughly ₹1.06 crore a year, or 1.1% of the contract value.
The bank may pass this cost on to the importer through higher hedging charges. Customers also cannot split the same hedge across multiple banks just to keep each contract below the $2 million limit.
Why is the RBI doing this now? The rupee weakened from ₹88.69 per dollar on October 1, 2025, to ₹96.31 on October 2, 2026. It is now just 0.5% away from its weakest level, recorded on May 20, 2026. Forex reserves had fallen to $734.6 billion by October 2, $51.1 billion below their September 4 peak. The RBI had also sold $136.8 billion in dollar forwards by the end of July and $200.1 billion by the end of August.
The logic is simple. When businesses expect the rupee to weaken, they try to lock in dollar prices before they rise further. The RBI is making this protection more expensive in the hope of reducing demand for dollar hedges and easing pressure on the rupee.
But hedging also helps businesses manage uncertainty. If protecting against a weaker rupee becomes more expensive, importers may face higher costs, which could eventually be passed on to customers.
The RBI isn't stopping businesses from buying dollars. It's making it more expensive for importers to lock in dollar prices in advance, while leaving exporters who sell dollars largely unaffected.
