External Stress Needs a Monetary Anchor

A persistent balance of payments shock is a broader macroeconomic and financial stability risk. India’s response would likely need to be credibly anchored by pre-emptive rate hikes, without which markets may repeatedly test financial conditions in a disorderly manner.

India is headed for a third consecutive year of BoP deficit, which is likely to exceed $50 billion in 2026-27. This is not a homegrown stress. High global interest rates, a technology-dominated growth theme, and elevated energy costs lie at its core.

The macroeconomic buffers that usually absorb such a BoP shock, like fiscal space, foreign exchange reserves, and durably low inflation, are also thinning. Inflation will likely breach 6% by late 2026 and remain elevated. The general government fiscal deficit could widen towards 8% of GDP. Foreign exchangereserves, while adequate in a traditional sense, appear thinner once adjusted for forward liabilities, with International Monetary Fund-style adequacy metrics approaching levels last seen during the 2013-14 stress episode.

Individually, none of these constitutes a crisis, but together they narrow the space for a passive policy stance.

Market sentiment has already shifted. Financial conditions are tightening through a weaker rupee, rising forward premia, and higher bond term premia, as investors price in the policy adjustment they expect will become necessary given tighter global capital constraints and elevated energy prices.

External Anchor
The difficulty with such market-led tightening is that it operates without an anchor. Currency weakness feeds into inflation expectations, which contribute to outflows, which in turn reinforce currency weakness. This cycle is not always destabilising, but it becomes harder to manage in the absence of a clear policy signal.

Pre-emptive rate hikes can provide that anchor, not by reversing the external shock (which domestic monetary policy cannot do), but by signalling alignment with tighter global financial conditions while the adjustment remains manageable and before expectations shift materially.

The inflation-targeting framework adds a specific consideration. It was designed for an environment of relative exchange rate stability, where interest rates operate as the primary lever on domestic prices. Under sustained currency pressure, the transmission from the exchange rate to inflation becomes faster and potentially non-linear.

Imported inflation through energy prices and depreciation interacts and compounds. The risk is not only higher near-term inflation but also the entrenchment of expectations at a higher level, a condition that, once established, could require more aggressive policy to reverse later than would have been needed to prevent it in the first place.

Some argue the rupee should bear the brunt of the BoP stress while domestic rates remain stable. This may be less effective in the current context. The textbook rationale is that a weaker currency is self-stabilising; it raises import costs while making exports and domestic assets more competitive, thereby narrowing the trade deficit and attracting capital inflows. This prescription, however, misses a nuance.

History suggests currency devaluation is most effective when it corrects pre-existing domestic imbalances, such as sustained high inflation, currency overvaluation or fiscal excesses, in a supportive global financial environment. When the source of stress is external, devaluation tends to be less stabilising and can instead amplify risk premia by unanchoring expectations.

In such episodes, currency weakness risks becoming self-reinforcing rather than equilibrating. The rupee’s roughly 12% decline since 2024, without a meaningful revival in portfolio inflows so far, is consistent with this logic.

Policy Mix
Rate hikes, however, address only part of the problem.

Supplementary measures will also be necessary. Allowing fuller fuel price pass-through may help limit fiscal slippage and remove price distortions that complicate the inflation outlook and delay demand adjustment.

Measures to attract stable capital inflows, restrain non-essential imports, and improve foreign exchange earnings could help reduce the adjustment burden on the exchange rate. Taken together, these would distribute the adjustment across policy levers rather than concentrating it on a single instrument. A coordinated approach may also carry greater credibility with markets than reliance on one tool alone.

The growth trade-off from higher interest rates is real and should be acknowledged. Tighter monetary policy raises borrowing costs and moderates domestic demand. At this stage of the cycle, however, the trade-off appears asymmetric. India’s cyclical position remains reasonably firm, suggesting calibrated tightening is unlikely to derail the expansion. The economy may still grow by 6-6.5% in 2026-27.

The greater material risk lies in the opposite direction.

The larger risk lies in waiting too long. If inflation expectations drift higher and markets force an adjustment that policymakers had hoped to defer, the eventual correction may be sharper, less orderly, and harder to manage. A measured front-loaded policy response, in this context, is not simply a trade-off against growth but a hedge against a more disruptive outcome.
