For years, the Strait of Hormuz appeared in India’s energy security discussions as a theoretical vulnerability — a scenario analysed in policy papers but rarely treated as an immediate risk. That perception changed dramatically in March 2026.

Following coordinated military strikes on Iranian nuclear facilities in late February, Iran declared the Strait of Hormuz effectively closed. Within days, tanker traffic through the world’s most critical oil chokepoint slowed sharply. Hundreds of vessels anchored outside the passage as shipping companies suspended transits due to security concerns. Several tankers bound for Asian destinations were attacked, further intensifying market fears.

The impact on energy markets was immediate. The Indian crude oil basket surged sharply within days, jumping from the range of roughly $60–70 per barrel seen earlier in the fiscal year to well above $110 per barrel at the peak of the disruption. What had long been treated as a hypothetical geopolitical risk suddenly became an operational shock to global energy supply.

The World’s Most Important Energy Chokepoint

The Strait of Hormuz sits between Iran and Oman and represents one of the narrowest yet most strategically significant maritime corridors in global trade.

At its narrowest point, the strait measures just over 50 kilometres across, while the navigable shipping channels are barely a few kilometres wide in each direction. Despite this narrow passage, an enormous share of global energy trade flows through this route.

Roughly 20 million barrels of crude oil and petroleum products transit the strait each day, representing approximately one-quarter of the world’s seaborne oil trade. In addition to crude, the corridor also handles a substantial share of global liquefied natural gas exports, primarily from Gulf producers.

The dependence on this corridor is particularly concentrated in Asia. Major economies such as China, India, Japan, and South Korea collectively account for the majority of oil shipments passing through Hormuz. For these countries, the strait is not merely a shipping route — it is the most critical single point of vulnerability in their energy supply chains.

A prolonged disruption would therefore not only affect oil prices but also threaten energy security across multiple continents.

India’s Dependence on Hormuz

India is the world’s third-largest consumer of crude oil, with daily consumption exceeding 5 million barrels per day. The country imports roughly 85–90% of its crude oil requirements, making it heavily exposed to global energy supply disruptions.

A significant portion of these imports originates from Gulf producers such as Iraq, Saudi Arabia, the United Arab Emirates, and Kuwait — all of which rely on the Strait of Hormuz for export routes.

As a result, close to half of India’s crude imports transit the strait in normal circumstances.

Even if diversification strategies reduce that exposure slightly, the scale of India’s energy consumption means that even partial disruption can create substantial economic stress. A 30% supply vulnerability still translates into more than 1.5 million barrels per day of crude imports at risk.

The dependence is even greater for certain fuels.

India imports roughly 60% of its LPG consumption, and the overwhelming majority of those shipments pass through the Strait of Hormuz. LPG is not merely an industrial fuel in India — it is the primary cooking fuel for hundreds of millions of households.

Natural gas imports are similarly exposed. A large share of LNG imports from Gulf producers also passes through the same maritime corridor, linking the strait directly to India’s fertiliser production, power generation, and city gas distribution networks.

How a Hormuz Crisis Spreads Through the Economy

A disruption in the Strait of Hormuz affects far more than crude oil prices. The shock spreads across multiple layers of the economy simultaneously.

Oil Import Costs

Higher crude prices immediately inflate India’s import bill. Oil imports already account for a meaningful share of the country’s external balance, and a sustained price surge significantly widens the current account deficit.

A sharp increase in crude prices can add billions of dollars to India’s annual import expenditure, placing pressure on the trade balance and foreign exchange reserves.

Inflation and Consumer Demand

Fuel costs feed directly into transportation, logistics, and manufacturing expenses.

Higher diesel and petrol prices raise freight costs across the economy, pushing up the prices of goods and services. If fuel prices are allowed to rise fully, inflation accelerates and consumer demand weakens.

If prices are controlled to protect consumers, oil marketing companies absorb the losses, compressing profitability across the energy sector.

Either way, the economic impact becomes unavoidable.

Fertilisers and Agriculture

India’s agricultural sector is closely linked to energy markets through fertiliser production.

Natural gas is a key feedstock for nitrogen-based fertilisers, and disruptions in LNG supply can reduce domestic fertiliser output. At the same time, India imports a large portion of phosphatic and potassic fertilisers.

A sustained energy supply shock therefore risks increasing fertiliser costs and potentially affecting agricultural productivity and food prices.

Shipping and Logistics

Maritime risk escalates dramatically during geopolitical conflict.

Insurance premiums for vessels operating in war-risk zones surge, increasing shipping costs. Tankers are often forced to take longer routes, raising freight expenses and delivery times.

In extreme cases, vessels may suspend operations entirely or sail with tracking systems turned off to avoid detection in conflict zones.

These disruptions increase the landed cost of imported commodities across the board.

Currency and Capital Flows

Energy shocks also influence currency markets.

As oil prices rise, the demand for foreign currency increases to pay for imports, putting downward pressure on the rupee. At the same time, global investors often reduce exposure to emerging markets during geopolitical crises.

The combination of rising oil prices and capital outflows can therefore amplify volatility in financial markets.

Strategic Reserves: A Limited Buffer

India maintains strategic petroleum reserves as a safeguard against supply disruptions.

The country currently holds roughly 5.3 million metric tonnes of crude oil in underground storage facilities, covering approximately 9–10 days of national consumption.

Oil marketing companies also maintain commercial inventories that extend total storage capacity to roughly 70 days of demand.

However, these commercial stocks are part of the normal operating cycle of refineries and distribution systems. They cannot be entirely diverted for emergency use without disrupting routine supply.

The actual crisis buffer is therefore significantly smaller than the headline numbers suggest.

Compared with other major Asian economies, India’s strategic reserves remain modest. Several countries maintain reserves capable of covering several months of consumption, providing far greater protection against prolonged supply shocks.

The Strategic Challenge Ahead

The Strait of Hormuz crisis highlights a structural vulnerability in India’s energy system.

Diversification efforts have increased the number of countries supplying crude oil to India, but the geographic concentration of Gulf exports means that the shipping route itself remains a bottleneck.

Reducing this vulnerability requires a multi-pronged approach.

Expanding strategic petroleum reserves is one obvious step. Increasing storage capacity would provide a larger buffer against temporary disruptions.

At the same time, diversification of supply sources toward regions such as West Africa, Latin America, and North America could reduce dependence on a single maritime chokepoint.

Investment in alternative energy sources — including renewables, nuclear power, and domestic gas production — can also reduce long-term reliance on imported fossil fuels.

A Structural Energy Risk

The events of March 2026 represent more than a temporary geopolitical shock. They serve as a reminder that the global energy system remains deeply intertwined with strategic geography.

For a country that imports the vast majority of its crude oil and consumes millions of barrels every day, even a partial disruption in a single shipping corridor can have outsized consequences.

The Strait of Hormuz has always been the world’s most important energy chokepoint.

What the recent crisis revealed is how thin the margin for disruption can be when national energy security depends on a corridor only a few kilometres wide.
