Reserve Bank of India’s problem is no longer just policy error, but policy incoherence

RBI Tried to Defend the Indian Rupee. It Ended Up Undermining It.

The Reserve Bank of India’s recent handling of the rupee has revealed something more serious than a bad call under pressure. It has revealed a central bank acting without a coherent policy hierarchy. On 27 March 2026, RBI abruptly directed banks to cap their net open rupee foreign exchange positions at $100 million by the end of each business day, with compliance required by 10 April. The intention was transparent: arrest the rupee’s slide, squeeze speculative and arbitrage positions, and signal resolve. The market’s first response seemed to vindicate the move. After closing at a record low of 94.84 per dollar on Friday, the rupee opened sharply stronger on Monday, rising to around 93.59-93.60. But the celebration lasted hours, not days. By the same session, the rupee had fallen to a record intraday low of 95.21 before likely RBI intervention helped it close at 94.83, almost unchanged. What looked like policy strength quickly turned into evidence of policy failure.

The episode matters because it shows why blunt currency management often backfires when it confuses symptoms for causes. The rupee is not weak because banks were enjoying too much freedom in their balance-sheet positioning. It is weak because India is confronting a serious external shock. Reuters reports that the rupee has been hit by heavy foreign investor sales, heightened geopolitical risk, and a sharp increase in oil prices linked to the widening Middle East conflict. Brent crude reached about $115 per barrel, and India imports about 90% of its oil needs. That combination worsens India’s external vulnerability, raises imported inflation risk, and makes a wider current account deficit more likely. In that environment, trying to defend the rupee through a sudden trading cap does not remove the pressure. It merely changes where the pressure shows up.

The reason the rupee initially rose is straightforward. RBI’s cap forced banks to unwind positions that had been built around the gap between the onshore USD/INR market and the offshore non-deliverable forward, or NDF, market. Reuters reports that these arbitrage positions were large, around $25 billion to $35 billion. To cut those positions, banks had to sell dollars in the local market, which mechanically pushed the rupee up at the open. This was not an improvement in India’s external position, not a revival in investor confidence, and not a reduction in oil-import dependence. It was a forced flow effect generated by a regulatory shock. That is why the initial rupee strength was always likely to be temporary.

The real damage came next. By forcing domestic banks to dump dollars onshore while simultaneously buying in offshore markets to rebalance exposures, RBI created a dislocation between the onshore and NDF markets. Reuters reports that the one-month NDF-onshore spread, which had normally been around 1 to 5 paise, blew out to more than 1 rupee at one point, before narrowing only to 40 to 50 paise. That is not a sign of a well-functioning intervention. That is a sign of a policy-induced pricing fracture. Once this wedge appeared, corporates and sophisticated clients did what rational economic agents always do. They arbitraged it. They bought dollars onshore where they were cheaper and sold in the NDF market where they were more expensive. Importers also stepped in to hedge near-term liabilities. In other words, RBI tried to suppress one arbitrage and ended up creating a more attractive one.

This is why it is too simplistic to say that RBI alone “crashed” the rupee. The rupee’s broader weakness predates this measure and reflects macroeconomic and geopolitical stress. Over India’s 2025-26 fiscal year, the rupee fell 11%, its worst annual drop since 2011-12. Reuters attributes this to trade frictions, geopolitics, sustained foreign outflows, and India’s vulnerability to an oil shock. What RBI did was not create the underlying depreciation trend. What it did do was make the market more disorderly, more volatile, and less confident in the policy framework. A central bank can survive a failed intervention. What it cannot easily survive is the impression that it no longer has a stable theory of what problem it is solving.

That is where the separate RBI deferral on capital market exposure rules becomes politically and institutionally relevant. On 30 March 2026, RBI officially deferred implementation of its amendment directions on capital market exposures from 1 April to 1 July 2026, explicitly citing representations from banks and industry bodies that had raised “operational and interpretational issues,” after which RBI also issued clarifications on acquisition finance and capital-market-intermediary exposures. This is not the same rule as the FX cap. But it contributes to the same impression: announce forcefully, discover operational defects, then retreat and clarify. That pattern is corrosive. A regulator does not build credibility by oscillating between severity and improvisation.

The banks’ response to the FX cap reinforces this reading. Reuters reports that lenders asked RBI for three months to comply because rapid implementation risked “disorderly unwinding” and losses. That is a remarkable indictment. When the regulated institutions immediately tell the central bank that compliance itself may destabilise the market, the policy has likely been introduced too abruptly or designed too crudely. Prudential tightening can be defensible. Emergency regulation can also be defensible. But both require sequencing, transition planning, and an understanding of market plumbing. RBI appears to have treated balance-sheet mechanics as an afterthought.

So what is RBI doing now? It appears to be fighting the rupee on too many fronts at once and with too little conceptual discipline. It is intervening in FX markets, imposing position caps, and at the same time showing elsewhere that it is willing to defer and revise major regulatory changes when operational realities become impossible to ignore. That is not a coherent anti-crisis doctrine. It is a sequence of reactive moves. Markets can tolerate tight policy. They can even tolerate pain. What they punish is inconsistency.

The academic point is simple. Exchange rates are prices that condense information about external balances, capital flows, inflation risk, and credibility. They cannot be durably stabilised by administrative shock therapy when the macro fundamentals are deteriorating. RBI’s latest intervention did not restore confidence in the rupee. It briefly bullied the price, fractured market structure, created a once-in-a-decade arbitrage window, and then watched the currency give back its gains. That is not effective central banking. It is policy incoherence in real time.
