RBI rupee defence is raising the cost of INR hedging

RBI rupee defence raises hedging costs

New limits on bank positioning and tighter restrictions around non-deliverable forwards (NDFs) are helping support the rupee. However, they are also making offshore USD/INR hedging via NDFs more expensive for foreign investors, especially further out the curve, where liquidity has been significantly impacted.

The Reserve Bank of India moved beyond routine spot intervention and into market-structure tightening to support the rupee. On 27 March 2026, it authorised dealers to keep their net open INR position in the onshore deliverable FX market within USD 100 million at the end of each business day, with compliance required by 10 April. The measure directly limits how much rupee risk banks can carry on their balance sheets.

A second step added further restrictions on the market. Market reporting indicates onshore banks were also prevented from offering or rebooking INR NDF contracts for clients. In addition, restrictions on transactions with related parties limit banks’ ability to run back-to-back hedging between onshore and offshore desks, reducing liquidity available to offshore clients.

Market impact and disruption

Taken together, these measures reduce dealer risk capacity, constrain the link between offshore and onshore rupee pricing, and raise the cost of arbitrage between the domestic forward market and offshore NDFs. The immediate policy goal is clear: reduce speculative pressure on the rupee and make it harder for offshore bearish positioning to feed directly into the domestic market.

Recent reporting suggests banks have responded by unwinding positions through selling dollars locally and buying abroad, which has helped widen the spread between domestic forwards and offshore NDF pricing. This has disrupted NDF markets, with some banks refusing to quote longer tenors beyond two years.

For foreign investors, the widening basis and reduced availability of offshore sell USD/buy INR liquidity are the central concerns. Under normal conditions, dealers help keep offshore and onshore pricing aligned by using balance sheet to arbitrage price differences. However, when banks face a hard cap on rupee open positions, that balancing function weakens. The hedge may still be available offshore, but pricing is materially wider and less reliable than onshore alternatives. Managing large size equity exposures offshore in such situations will present a significant challenge.

The full extent of the disruption in offshore markets will become clearer in the coming days, as current pricing remains limited to small sizes and subject to significant scrutiny. Against this backdrop, clients should consider how best to access alternative hedging channels.

Implications for hedging access and execution

While offshore NDF markets have been significantly disrupted, deliverable hedging products remain available onshore. Offshore investors should actively explore establishing access to onshore bank desks. However, this is not a frictionless shift. Onshore hedging requires full KYC and onboarding with local counterparties, as well as compliance with regulatory requirements, including demonstrating an underlying exposure to support hedge transactions.

Product flexibility may also be more limited. Structures such as hedge rollovers (HRRs) and deferred premium options are typically not permitted onshore. Finally, not all banks active in the offshore NDF market have a meaningful onshore presence, which means some investors may need to reassess and potentially expand their counterparty panel to effectively access onshore liquidity.

Implications for pricing and hedge costs

This matters because the carry embedded in USD/INR NDFs no longer only reflects India–U.S. rate differentials. It will also absorb a larger liquidity and regulatory premium. As the RBI tightens access and banks lose flexibility to warehouse rupee risk, the long end of the hedge curve becomes harder to price cleanly.

A foreign investor hedging INR exposure out to five years is therefore facing a double burden: the usual cost of carry, plus a wider basis created by tighter market structure. This is inferred from the RBI’s position limits, reported NDF restrictions, and the shape of the forward curve.

The result is a structurally more expensive hedge offshore. For investors in Indian local-currency bonds, long-duration private assets, or strategic equity positions, the all-in cost of protecting INR exposure back into dollars has risen. Longer-dated hedges are also likely to be less liquid and less predictable. Some investors may respond by shortening tenor to reduce upfront carry, but that simply shifts the problem into rollover risk and future basis uncertainty.

From the RBI’s perspective, that may be an acceptable trade-off. The rupee strengthened sharply after the open-position cap was announced, with market reports noting a rebound from record lows as banks unwound positions. If the objective was to disrupt one-way positioning and buy time for the central bank, the policy appears to have had some immediate effect.

For offshore users, however, the message is different. INR hedging is no longer just a macro or rates question. It is increasingly a question of access and regulation. As long as the RBI continues to use structural tools to defend the currency, foreign investors should expect USD/INR hedging through NDFs to remain more expensive, less seamless, and more sensitive to policy shifts.

Bottom line

The RBI’s latest moves may help stabilise the rupee in the near term, but they do so by making the hedging channel less efficient. For foreign investors, the widening of USD/INR carry out to five years is a signal that regulation is becoming part of the hedge cost. In this environment, access to onshore deliverable hedging markets will become increasingly important, and investors should actively evaluate their ability to utilise these channels.
