The Reserve Bank of India has expanded the scope of a cash-deposit requirement linked to foreign-exchange derivatives, as policymakers seek to curb destabilising speculation and manage pressure on the rupee. Under the measures announced in October 2026, authorised banks are required to maintain a 20% cash reserve against a wider set of rupee-involved foreign-exchange derivative transactions, including those used to hedge their own assets and liabilities. The RBI has also tightened the permitted use of non-deliverable forwards by banks and primary dealers operating in India’s International Financial Services Centre.
What is the 20% forex reserve rule?
Foreign-exchange derivatives are contracts that help businesses and financial institutions manage currency risk. A company with dollar revenues or payments may use a derivative to reduce uncertainty about the rupee value of a future transaction. A non-deliverable forward, or NDF, allows parties to settle the difference between agreed exchange rates without physically exchanging the currencies.
Expanding the reserve requirement makes covered transactions more costly in terms of cash tied up by banks. The intention is to discourage excessive speculative positions and reduce incentives for trades that amplify short-term pressure on the rupee. The precise effect on individual customers will depend on the type of contract, bank pricing and how the institution manages the added cost.
Who may be affected?
Authorised banks are directly affected by the reserve requirement. Businesses that use forex derivatives for legitimate hedging could also see changes in pricing or availability as banks reassess their balance-sheet costs. Importers, exporters, investors and companies with foreign-currency borrowings should discuss the impact with their treasury teams or banking partners instead of assuming every contract is treated identically.
The RBI’s NDF restrictions separately limit offerings by banks and primary dealers in the IFSC to non-residents for hedging purposes rather than speculation. Firms should refer to the actual regulatory circular and any subsequent clarifications for the complete scope, dates and exemptions.
Will the rupee strengthen?
Regulatory measures can influence market behaviour, but they cannot by themselves determine the exchange rate. The rupee also responds to crude-oil prices, foreign portfolio investment, trade balances, US interest-rate expectations, global risk appetite and demand for dollars from importers. A short-term rise after a policy announcement should not be treated as evidence of a permanent trend.
Businesses with foreign-currency exposure should review their hedge ratios, cash-flow forecasts, counterparty arrangements and approved treasury policies. Retail investors should avoid treating currency headlines as a trading signal. Exchange-rate moves remain uncertain, and derivatives can create substantial losses when used without appropriate expertise.
