The hold with room to cut
The RBI's Monetary Policy Committee held the repo rate at 5.25 percent in June and maintained a neutral stance, a decision that looks straightforward but masks a genuine tension. On inflation alone, the RBI has room to ease: CPI is running near its 4 percent target, projected around 4.6 percent for FY27, and growth has been trimmed - the textbook setup for supportive policy. What stayed the central bank's hand was the currency. With the rupee at record lows near 92 per dollar and a hawkish Fed keeping the dollar firm, cutting rates would have widened the rate differential and risked accelerating the rupee's decline. The RBI is holding not because inflation demands it but because the currency does.
The reaction function, decoded
The RBI's reaction function has evolved. Having spent years establishing flexible inflation targeting and winning hard-fought credibility on price stability, the central bank now operates in a regime where inflation is broadly under control and the binding constraints are external: the exchange rate and the global rate environment set by the Fed. The RBI weights currency stability heavily because a disorderly rupee fall would import inflation, unsettle the large foreign-investor base in Indian markets, and threaten the financial stability it prizes. In 2026 that means the RBI's easing room is determined less by Indian inflation than by the Fed's stance and the rupee's behaviour - a reaction function that imports a measure of the developed world's monetary tightness.
India has reached the enviable position where its own inflation is no longer the problem - and the uncomfortable position where its monetary policy is partly hostage to the Fed and the rupee. The RBI can cut when the dollar lets it, not when Indian growth asks for it. That is the price of deep integration into global capital markets.
The rupee and the policy bind
The rupee is the clearest expression of the RBI's bind, and the central bank manages it actively. The RBI intervenes in the foreign-exchange market to smooth the rupee's depreciation, drawing on its substantial reserves to prevent disorderly moves, while accepting gradual depreciation as the equilibrium adjustment to a firm dollar and India's structural current-account deficit. This managed-float approach gives the RBI a second lever beyond the policy rate, but it is not costless: heavy intervention drains reserves and tightens domestic liquidity, working against the easing the growth picture would otherwise invite. The rupee's record low is therefore both a symptom of the bind and a constraint that deepens it.
| Horizon | Most likely | Rationale |
|---|---|---|
| Jun 2026 | Hold (done) | Inflation allows, rupee constrains |
| H2 2026 | Hold / shallow cut | If rupee stabilises |
| Trigger to ease | Fed easing | Relieves the currency constraint |
| Tool | FX intervention | Manages the rupee alongside rates |
Scenarios for the policy path
Our base case is an extended hold with the RBI easing only cautiously and only if the rupee stabilises, using FX intervention to manage the currency in the meantime. The dovish case is a Fed that eventually eases, relieving the currency constraint and allowing the RBI to cut into a still-strong growth picture - the best outcome for Indian assets. The hawkish tail is continued rupee weakness, driven by a firm dollar and outflows, that forces the RBI to stay tight or even tighten to defend the currency, sacrificing some growth. For investors the message is that the RBI's path runs through Washington and the rupee as much as through Mumbai and Indian inflation.
