Recent escalation in tensions involving Iran, along with risks around the Strait of Hormuz, has injected fresh uncertainty into oil markets. This matters directly for India, which imports nearly 85–90 percent of its crude oil and about half of its natural gas, much of it from the Middle East.
Higher oil prices have historically widened India’s current account deficit (CAD) by raising the import bill. The vulnerability, however, is not only immediate. As past deficits carry forward and adjustment is gradual, the effects of oil shocks persist well beyond the initial price increase. Oil price shocks therefore remain enduring macroeconomic risks.
To assess the scale of this risk, it is useful to examine how oil price movements transmit through the current account.
Immediate And Persistent Effects
The link between global oil prices and India’s current account is both immediate and persistent. Beyond the initial impact, adjustment is slow. Exchange rates respond, demand shifts, and contracts are repriced over time. As a result, earlier price increases continue to weigh on the external balance. Once the CAD widens, it does not correct quickly.
This creates a compounding effect, where earlier shocks continue to magnify current pressures. Oil price increases therefore not only widen the CAD but also act as a sustained drag on the economy. Persistence alone, however, does not capture the full extent of risk.
Risks Rise Non-Linearly
As oil prices rise beyond certain thresholds, the deterioration in the external balance accelerates. From a baseline of about 80 dollars per barrel and a CAD of 0.7–0.8 percent of GDP, the CAD could widen to 1.4–1.5 percent at 100 dollars. This remains manageable.
Beyond this point, the pace of deterioration increases. At 120 dollars, the CAD could reach 2.1–2.2 percent of GDP, signalling rising external stress. At 150 dollars, it could move to 3.2–3.3 percent, implying a significant weakening in external stability and greater reliance on external financing. At 200 dollars, the CAD could approach 5 percent of GDP, indicating a severe macroeconomic shock.
The pattern is clear. Each incremental increase in oil prices imposes a disproportionately larger burden on the current account.
Beyond The Current Account
The impact extends beyond the current account into broader macroeconomic conditions.
A higher import bill increases demand for dollars and puts pressure on the rupee. Depreciation then raises the domestic cost of imports, reinforcing pressure on the external balance. At the same time, elevated oil prices feed into inflation, complicating monetary policy and constraining growth.
The result is a tightening of macroeconomic conditions at a time when external stability is already under strain.
India’s buffers provide only partial protection. Strategic petroleum reserves are limited relative to potential disruptions, and supply remains concentrated in geopolitically sensitive regions. While the economy has absorbed moderate oil shocks in the past, the scale and persistence of shocks remain the key determinants of stress.
Rethinking External Stability
These dynamics point to a more complex policy challenge. Managing oil shocks is not only about absorbing price increases, but about limiting how they propagate through the economy.
This requires balancing inflation control with growth, exchange rate stability with competitiveness, and short-term adjustment with long-term resilience. External stability becomes central, as sustained CAD expansion increases reliance on volatile capital flows.
Energy security must therefore be treated as part of macroeconomic strategy. Reducing exposure is key. Strategic reserves can buffer short-term disruptions, while diversifying import sources can reduce vulnerability to regional shocks.
Over time, reducing structural dependence on imported fuels becomes essential. The energy transition, including renewables, storage, grid resilience, and efficiency, is therefore not only a climate objective but a macroeconomic one. The goal is to build enough flexibility in the system so that external shocks do not translate into disproportionate economic stress.
The task is not only to respond to the current episode, but to ensure that the next shock does not test the limits of India’s external stability.
