The renewed military confrontation between the United States and Iran has once again pushed West Asia to the edge. Financial markets have reacted predictably—equities have slipped, crude oil prices have surged and investors have rushed towards safe-haven assets. Brent crude has climbed above $76 a barrel following fresh US strikes on Iranian targets and fears of disruptions in the Strait of Hormuz, sending Indian stocks lower.

For India, however, the real concern is not a day of red on Dalal Street. It is the possibility of a prolonged geopolitical crisis that could quietly erode economic growth, reignite inflation and complicate the Reserve Bank of India’s monetary policy. More importantly, it could test the resilience of India’s banking system—not through direct exposure to Iran, but through second-order effects that are often underestimated.

India imports nearly 85% of its crude oil requirements, making it one of the world’s most vulnerable major economies to energy shocks. Every sustained increase in oil prices widens the import bill, weakens the rupee, raises transport and logistics costs and eventually feeds into consumer inflation. If tensions continue to escalate and shipping through the Strait of Hormuz is disrupted, the impact could be significantly larger than markets currently anticipate.

This is where banking enters the picture.

Banks may not have meaningful lending exposure to Iran, but they are deeply exposed to the sectors that suffer when oil prices remain elevated. Airlines face higher aviation fuel costs. Paint manufacturers, tyre companies, chemicals, plastics and logistics firms all experience margin pressure. MSMEs dependent on imported raw materials face rising working capital requirements. Consumers, meanwhile, postpone discretionary spending as inflation eats into disposable incomes.

The result is a gradual deterioration in credit quality rather than an immediate banking crisis.

Higher inflation also narrows the RBI’s room to support growth through lower interest rates. If crude remains elevated for several months, the central bank may have to prioritise price stability over monetary easing. Higher borrowing costs translate into slower credit demand from businesses and households, affecting loan growth precisely when banks have been enjoying one of their healthiest credit cycles in years.

The indirect impact could extend beyond lending.

India receives billions of dollars in annual remittances from the Gulf, where millions of Indians are employed. Any prolonged regional instability affecting economic activity in the Gulf could weaken remittance inflows, hurting household consumption in several Indian states, particularly Kerala, Telangana and Uttar Pradesh. Lower household incomes eventually affect retail banking, housing finance and consumption-led credit growth.

Fortunately, India’s macroeconomic fundamentals today are far stronger than they were during earlier oil shocks. Foreign exchange reserves remain comfortable, banks are better capitalised, non-performing assets have fallen sharply over the past few years, and corporate balance sheets are considerably healthier. The RBI has repeatedly argued that the domestic economy possesses sufficient resilience to withstand external shocks, even while acknowledging that geopolitical risks remain a significant threat.

That resilience, however, should not breed complacency.

Every geopolitical crisis follows a familiar economic chain reaction: higher oil prices trigger inflation; inflation pressures central banks; tighter financial conditions slow investment and consumption; slower growth eventually affects corporate earnings and loan repayments. The banking sector often feels the consequences long after the headlines have disappeared.

There is another lesson policymakers should remember. India’s energy security is inseparable from its economic security. Every crisis in West Asia reinforces the urgency of diversifying crude import sources, accelerating the transition to renewable energy, expanding strategic petroleum reserves and reducing dependence on imported fossil fuels. These are no longer environmental goals; they are macroeconomic necessities.

The renewed US-Iran tensions may eventually subside, as previous confrontations have. But if the conflict broadens or shipping lanes remain under threat, India could face a familiar combination of imported inflation, currency volatility and slower growth. The immediate market correction may prove temporary. The economic consequences, however, could linger much longer.

For Indian banks, the biggest risk is unlikely to come from direct exposure to the conflict. It will come from financing an economy suddenly forced to pay a much higher price for energy.
