What Happened
- The Reserve Bank of India (RBI) rolled out some of its toughest currency market measures in over a decade, targeting speculative trading in the offshore rupee market amid the rupee's successive record lows.
- On April 1, 2026, the RBI prohibited banks from offering rupee Non-Deliverable Forward (NDF) contracts to resident and non-resident corporate clients, effectively choking off a key speculative instrument.
- In a related move, the RBI capped banks' daily net open positions (NOP) in the onshore deliverable rupee market at $100 million, to be implemented by April 10, 2026.
- Rebooking of any forex derivative contracts — including dealings with related parties — was also prohibited, closing arbitrage loopholes.
- The offshore rupee NDF market trades an average of $149 billion a day — approximately twice the size of the onshore equivalent — making it a significant force in rupee price discovery.
- Following the measures, the rupee posted its biggest single-day gain in more than 12 years, strengthening as much as 1.8% to 93.14 per dollar on April 2 — its strongest appreciation since September 2013.

Non-Deliverable Forwards (NDFs) and the Offshore Rupee Market
A Non-Deliverable Forward (NDF) is a cash-settled currency derivative contract. Unlike a standard forward contract — where the underlying currency is physically exchanged at maturity — an NDF settles the net difference between the contracted rate and the prevailing spot rate, denominated entirely in a convertible currency (typically the US dollar). NDFs emerged for currencies with capital controls, where direct currency exchange is restricted. Because Indian residents face capital account restrictions under the Foreign Exchange Management Act (FEMA), 1999, an offshore NDF market developed at financial centres like Singapore, Hong Kong, London, Dubai, and New York — allowing international participants to take positions on the rupee without being subject to RBI regulations.
- The INR-NDF market is the second-largest NDF market globally by average daily turnover.
- At $149 billion per day, the offshore INR-NDF market is approximately twice the size of the onshore deliverable forward market.
- NDF pricing can diverge from onshore rates when capital controls or market sentiment differ — creating arbitrage opportunities that RBI sought to close.
- Prior to this ban, Indian banks could intermediate NDF contracts for both resident and non-resident corporate clients.
Connection to this news: By prohibiting banks from offering NDF contracts to corporates, the RBI effectively cut off a major channel through which speculative bets against the rupee were being placed in the offshore market — directly targeting the source of downward pressure on the currency.
RBI's Forex Market Intervention Tools
The RBI manages exchange rate volatility through a range of direct and indirect instruments. Direct interventions involve the RBI buying or selling dollars in the spot and forward markets to influence the rupee's level. Indirect regulatory tools include setting banks' Net Open Position (NOP) limits — which cap the amount of unhedged currency exposure a bank can carry — and restricting categories of derivative instruments that can be offered to market participants. The RBI has previously used all of these tools, but the combination of NOP caps and NDF restrictions deployed in April 2026 is among the most aggressive regulatory packages in the post-2008 era.
- Net Open Position (NOP) limit: A ceiling on the difference between a bank's total forex assets and liabilities (long vs. short positions). A $100 million daily cap forces banks to rapidly unwind excess positions.
- Prior to the April 10 deadline, banks reportedly held large arbitrage positions — reportedly totalling $30 billion — between onshore and offshore rupee markets, which they were now forced to unwind.
- The RBI's foreign exchange reserves stood at approximately $650–670 billion at the start of 2026, giving it significant capacity for direct dollar-selling intervention.
- RBI uses forex reserves to intervene both in spot markets (immediate effect) and forward/swap markets (deferred effect).
Connection to this news: The NOP cap and NDF ban work in tandem — the NOP cap limits banks' ability to build speculative positions, while the NDF ban removes the offshore instrument through which those positions were often hedged or magnified.
Exchange Rate Policy and India's Capital Account Architecture
India operates a managed float exchange rate regime — the rupee's value is determined by market forces, but the RBI intervenes when volatility is deemed excessive or when currency movements threaten macroeconomic stability. This is sometimes called a "dirty float." India's capital account is partially open: foreign direct investment (FDI) is largely free, portfolio investment (FPI) operates through a regulated route, and full convertibility of the capital account remains a long-term aspiration rather than current policy. FEMA, 1999 governs all cross-border capital and current account transactions, and RBI has wide regulatory authority over banks' forex dealings under the Banking Regulation Act and the RBI Act, 1934.
- India has never moved to full capital account convertibility, partly to preserve RBI's ability to manage exchange rate volatility.
- The Tarapore Committee reports (1997 and 2006) outlined preconditions for capital account convertibility — including fiscal consolidation, low inflation, and financial sector strength.
- A falling rupee raises import costs (especially crude oil and gold), worsens the current account deficit, and can trigger imported inflation — hence the RBI's strong preference for stability.
- The rupee hit successive record lows in early 2026, driven by the Iran war, dollar strength, and large portfolio outflows — creating the conditions for this aggressive regulatory response.
Connection to this news: The April 2026 measures represent the RBI's choice to use regulatory tools (rather than purely reserve-burning interventions) to tackle speculative pressure — a sign that the central bank prefers sustainable regulatory barriers to short-term dollar sales.
