More Than Oil: Why the U.S. Hormuz Blockade is a Serious Risk for India

Talks Between U.S. and Iran Fail to Reach a Deal

Talks between the U.S. and Iran in Islamabad broke down after a full day of negotiations. Following the failure, the United States announced a naval blockade targeting vessels linked to Iranian ports, casting a shadow over hopes of stability in global energy markets.  Washington has said that ships passing through the Strait of Hormuz toward non-Iranian destinations will not be stopped. But markets have not taken much comfort from that assurance. 

Tankers are already becoming cautious. Insurance premiums are rising. Freight costs are being revised upward. Oil crossing $100 per barrel reflects not just supply concerns but a repricing of risk around one of the most important shipping lanes in the world.

Strait of Hormuz in FocU.S. After U.S. Blockade Threat

Shipping through the Strait of Hormuz came to an immediate halt after U.S. President Donald Trump announced a blockade on Iranian ports, set to take effect at 1400 GMT on Monday. 

Traffic in the Strait, which had already been moving at reduced levels, then came to a complete standstill, with several ships seen turning back mid-transit.

Situation in Strait of Hormuz

The situation in the Strait of Hormuz is not one problem. There are several problems happening at the same time. Crude oil has surged past $100 per barrel on Monday. LNG supplies face disruption. LPG imports are at risk. Shipping costs are going up. And sitting beneath all of this is a structural issue India has not fully resolved, its dependence on the Gulf for energy, raw materials, and a large share of household income through remittances.

The real question now is not whether supplies get disrupted. It is how fast rising costs start showing up in what people pay for fuel, cooking gas, groceries, and everything that gets transported across the country.

Oil: Cost Shock Is Already Underway

Around half of India's crude oil imports pass through the Strait of Hormuz. Even without a complete closure, three things are already happening, freight rates are going up, insurance costs are rising, and delivery timelines are getting longer. Each of these adds to the cost of crude before it even reaches an Indian refinery.

That higher landed cost feeds into fuel prices. Fuel prices feed into transport costs. Transport costs feed into the price of almost everything else. India imports around 88%-89% of its crude oil requirements, which means there is very little domestic production to meet the nation’s oil needs, when global supply tightens. The country's strategic petroleum reserves can cover roughly 9.5 days of national demand. The storage left is not sufficient for consumption, if disruptions last weeks or months.

LNG: A Less Visible but Serious Risk

Between 40%-55% of India's LNG imports move through the Strait of Hormuz. This does not get as much attention as crude oil, but the consequences of a disruption are significant. LNG is also used in power generation, fertilizer production, and city gas distribution networks. Unlike oil, where alternative suppliers exist and rerouting is at least possible, gas markets tighten quickly and replacement supplies typically come at a much higher cost.

Any sustained reduction in LNG availability puts pressure on electricity generation capacity, raises input costs for the fertiliser sector, and affects the expanding network of piped natural gas that millions of households and businesses now depend on.

LPG: A Direct Hit on Household Budgets

Of all the energy categories, LPG is where India's exposure is most direct. About 60% of India's LPG demand is met through imports, and roughly 90% of those imports come through the Strait of Hormuz. This is not an abstract market figure. It connects directly to the cost of cooking gas for hundreds of millions of Indian households.

If LPG import costs rise, the government faces a choice between passing the increase on to consumers or absorbing it through higher subsidies. Either way there is a real cost either to household budgets or to public finances. At a time when fiscal space is already tight, this is a pressure the government would rather not be dealing with.

Inflation: The Second-Round Effect

Energy costs do not stay within the energy sector. When crude and gas prices rise, the effects spread through the wider economy. Transport costs go up, which affects the price of moving goods from farms to markets and from factories to consumers. Fertiliser costs rise, affecting agricultural input prices. Chemicals and manufacturing become more expensive. Packaging costs increase. FMCG companies face margin pressure and eventually pass costs on.

This is where the impact moves from markets to everyday life. The inflation that results from an energy shock of this kind is broad-based and persistent. It affects low-income households the hardest, since a larger share of their spending goes toward food, fuel, and transport, the three categories most directly exposed to an oil price rise.

The Rupee and India's External Account

Higher oil prices directly expand India's import bill. India was already running a current account deficit before this crisis. If crude stays elevated for an extended period, that deficit widens further. A wider current account deficit puts pressure on the rupee. A weaker rupee makes imports more expensive in rupee terms, which affects the inflation and tightens financial conditions further.

This creates a difficult situation for the Reserve Bank of India. Cutting interest rates to support growth becomes harder when inflation is rising. Holding rates steady or raising them to defend the rupee constrains growth. The RBI's flexibility to respond to a slowdown gets reduced precisely when the economy may need support the most.

Manufacturing and Petrochemicals

India's industrial sector is closely tied to hydrocarbon prices. When crude rises, so do the costs of plastics and polymers, paints and chemicals, and packaging materials. These are inputs for a wide range of industries  from consumer goods to construction to pharmaceuticals. Manufacturers either absorb the higher costs, which compresses margins, or they pass them on, which adds to inflation. Neither outcome is straightforward.

Companies with export exposure to the Middle East face an additional problem. With shipping disrupted and project activity in Gulf countries slowing down due to the conflict, orders are being delayed and delivery schedules are being pushed back. This affects Indian engineering, infrastructure, and industrial companies that have built meaningful businesses exporting to the region.

Why It Happened and What It Means

The trigger for the current situation is the failure of US-Iran negotiations, with both sides unable to close gaps on nuclear activity, regional influence, and control of key waterways. The U.S. blockade is designed to increase economic pressure on Iran without formally closing the Strait of Hormuz to all global traffic.

In practice, once military escalation reaches a critical shipping lane, the effects extend well beyond the stated target. The blockade may be directed at Iran. But for India, the exposure is broader and cuts across energy, inflation, fiscal policy, industry, and the incomes of millions of families who depend on Gulf employment.

India is not a party to this conflict. But the consequences are affecting its economy  regardless.
