The largest-ever disruption of ⁠energy supplies caused by the US-Israel war against Iran has left major global economies struggling with energy shortages. Amid the possibility of a new round of negotiations between Iran and the US, concerns over supply disruptions appear to cool down with oil prices dropping in early trade on Thursday.

However, the Iran war has damaged as much as $58 billion worth of energy infrastructure, according to an estimate by Rystad Energy. This does not bode well for economies like India, as its dependence on imported crude oil grew to over 88.5 per cent in the first 10 months of the current financial year FY26.

 

India's Oil Vulnerability — Five Key Numbers

ENERGY SECURITY — WEST ASIA CRISIS 2026
As the US-Israel war against Iran disrupts global energy supplies, how exposed is India — and where are the fault lines?
OIL IMPORT DEPENDENCE
India meets barely 1 in 8 barrels from domestic soil
India's crude oil import dependence climbed to 88.5% in the first 10 months of FY26 — a record high. Domestic output of roughly 700,000 barrels per day covers only about 13% of total demand. Total crude imports in FY25 stood at 244.5 million metric tonnes, making India the world's second-largest crude importer.

THE HORMUZ CHOKEPOINT
Nearly half of India's crude passes through a single strait
The Strait of Hormuz — the narrow waterway between the Persian Gulf and the Gulf of Oman — is the single most critical node in India's energy supply chain. Any closure or disruption here would halt 40–50% of India's crude oil imports almost immediately, with no short-term alternative route available at scale.

IRAN ENERGY INFRASTRUCTURE
$58 billion in damage — the largest-ever energy supply disruption
The US-Israel war against Iran has caused an estimated $58 billion in damage to energy infrastructure, according to Rystad Energy — the single largest disruption of energy supplies ever recorded. West Asia still accounts for roughly 60% of India's import basket, with Saudi Arabia, Iraq, UAE and Iran among its key historic suppliers.

What this means for India
Supply shortfall risk
Damaged Iranian infrastructure reduces regional export capacity, tightening supply for buyers across Asia including India.
Price pressure
Any prolonged disruption in West Asian output drives up global crude prices, raising India's import bill significantly.
Diversification urgency
India diversified sourcing since 2005 to include Africa and Americas, but West Asia's 60% share means no quick substitute exists at scale.
SUPPLIER CONCENTRATION
Top 5 suppliers now account for 82.7% of India's crude — up from 75.2%
India's crude import basket has become more concentrated, not less. The combined share of the top five suppliers — Russia, Iraq, Saudi Arabia, UAE and the US — rose from 75.23% in 2022-23 to 82.7% in 2024-25, indicating a counter-intuitive tightening of dependency even as India sought diversification.

STRATEGIC PETROLEUM RESERVES

India's Strategic Petroleum Reserves (SPR) — maintained in underground caverns — have a total capacity of 5.33 million tonnes. Current stocks stand at 3.37 million tonnes, or about 63% of total capacity, according to the Ministry of Petroleum and Natural Gas. A full reserve would provide a stronger cushion against supply shocks.

As the crisis in West Asia continues to shape global energy security, what lessons do past oil shocks offer for navigating the current situation? Let’s examine. But first, a brief overview of India’s energy mix and import dependence.

India’s energy basket

The unfolding crisis in West Asia has a profound impact on India’s energy market, as the country is heavily dependent on West Asia for its energy imports. 

Crucially, a huge chunk of those imports passes through the Strait of Hormuz – a waterway between the Persian Gulf and the Gulf of Oman. Around 2.5–2.7 million bpd of India’s crude imports – accounting for almost half of the country’s total oil imports – have transited the strait in recent months; the longer-term average is around 40 per cent.

With a population of 1.46 billion and a fast growing economy, India has seen a steady growth in its energy demand. This demand is met through various energy sources, with coal remaining the largest source of energy supply.

According to the International Energy Agency (IEA), around 48.4 per cent of India’s total energy demand is met through coal and coal products as of 2023. Crude oil constitutes the second largest source, accounting for 24.7 per cent of total energy supply. 

As coal is the mainstay of India’s energy basket, its domestic production has registered a considerable growth, with 1047.5 million tonnes produced in 2024-2025 compared to 997.8 million tonnes in 2023-2024. 

On the other hand, domestic oil production meets only about 13 per cent of total demand. In 2023, domestic oil production averaged around 700 thousand barrels per day. As a result, India remains heavily dependent on crude oil imports.

India’s strategic petroleum reserves (SPRs), which have a capacity to store 5.33 million tonnes of crude oil, are currently holding 3.37 million tonnes of oil, or just about two-thirds of their total storage capacity, according to the Ministry of Petroleum and Natural Gas (MoPNG).

Energy import profile

India is the second largest importer of crude oil, with total crude oil imports standing at 244.5 million metric tonnes in 2024-2025. This means that nearly 90 per cent of India’s energy demand is met through imports. 

West Asia has traditionally been India’s primary source of crude oil imports, with over 70 per cent of its crude oil coming from Saudi Arabia, Iran, Iraq, Kuwait and the United Arab Emirates. 

Although India has sought to diversify its sources of oil supply since 2005 and included supplies from African countries like Nigeria and Angola as well as Venezuela, West Asia still constitutes about 60 per cent of the country’s energy import basket. 

Currently, Russia, Iraq, Saudi Arabia, the UAE and the US are the top five crude oil suppliers. The total share of imports from these countries increased from 75.23 per cent in 2022-23 to 82.7 per cent in 2024-25.

Oil shocks: What history tells us

But the ongoing crisis in West Asia once again highlights the vulnerability of energy supplies to geopolitical tensions. At the same time, global oil shocks are not a new phenomenon. Let’s see how India navigated some of the major shocks in the past. 

The 1973 oil crisis 

During the 1973 Arab-Israeli war, Arab members of the Organization of Petroleum Exporting Countries (OAPEC) imposed an embargo on the US and other countries that were supporting Israel. The embargo reduced about 7 percent of the global supply, while embargoed countries faced a combined shortage of 4.5 million barrels of oil per day.

This was one of the first crises, when global economies were jolted by the strategic power of oil. As part of a coordinated move by Arab countries to cut production, oil prices surged by 70 per cent to $5.11 per barrel. The impact was severe, pushing major economies like the US into recession that lasted until 1975. In the UK, this led to the fall of the Conservative government led by Ted Heath.

For India, the oil shock had a significant economic impact. Its import bill rose sharply from about $500 million in 1973 to $1.3 billion dollars in 1974. Rising petroleum prices and shortages of petroleum-based fertilisers even affected India’s agricultural output.

The Five-Year Plan, launched in 1974, had estimated oil import expenditure at $3.8 billion by 1978. However, the sharp increase in oil prices – reaching around $8 per barrel – proved the estimate inadequate. Inflation surged by 20 per cent, while the demand for petroleum stagnated and imports declined. 

The 1979 oil crisis

The next major shock followed in 1979 after the Iranian Revolution. Political instability led to a decline in Iran’s oil production – around 7 per cent of world production at the time. This resulted in a rise of oil prices from $13 per barrel in mid-1979 to $34 per barrel in mid-1980. The crisis hit the global economy still recovering from the first oil shock just a few years earlier. 

Amid these conditions, India was compelled to approach the International Monetary Fund (IMF) for assistance to address its balance of payment issue. This engagement is often seen as laying the foundation for the process of economic liberalisation, as the IMF support came in exchange for structural adjustments.
