What Happened
- Following the US-Israeli military strikes on Iran (February 28, 2026), Iran threatened to close the Strait of Hormuz, with the IRGC Navy transmitting messages to vessels warning that "no ship is allowed to pass."
- The actual oil flows through the Strait of Hormuz have been disrupted, triggering immediate global oil price surges and creating supply uncertainty for major Asian importers, particularly India, China, Japan, and South Korea.
- India issued an urgent advisory for seafarers operating in the region, reflecting direct concern over the safety of Indian crew members and oil tanker operations.
- India's oil ministry indicated no immediate supply disruption given existing crude inventories, but flagged medium-term risks if the blockade persists beyond the current 10–15 day inventory buffer.
- Alternative supply routes — Russia, US West Texas Intermediate, West African crude, and Latin American suppliers — are being assessed as contingency options.

The Strait of Hormuz: Geography, Strategic Significance, and Historical Context
The Strait of Hormuz is a narrow waterway connecting the Persian Gulf to the Gulf of Oman and the Arabian Sea. It is the world's most strategically important maritime chokepoint for energy flows. At its narrowest, the strait is only 39 kilometers wide, with navigable shipping lanes of only 3 kilometers in each direction. It is bounded by Iran to the north and Oman and the UAE to the south.
- Approximately 20 million barrels of crude oil per day transited through the Strait of Hormuz in 2024, representing roughly 20–21% of total global oil consumption and nearly a third of all seaborne traded oil.
- An estimated 20% of global Liquefied Natural Gas (LNG) shipments also pass through the strait — primarily from Qatar, the world's largest LNG exporter.
- Major oil exporters that ship through the strait: Saudi Arabia, UAE, Kuwait, Iraq, Iran, and Qatar.
- The main bypass alternative — the East-West Pipeline (Petroline) in Saudi Arabia — has a capacity of approximately 5 million barrels per day (significantly less than the 20 million that transit through Hormuz).
- The Abu Dhabi Crude Oil Pipeline (ADCOP) offers another partial bypass, with capacity of about 1.5 million barrels per day to the port of Fujairah on the Gulf of Oman.
- Iran itself exports oil through the strait, meaning any blockade would also harm Iranian revenues — a factor that has historically limited Iran's willingness to fully close the waterway.
Connection to this news: The disruption to Hormuz flows is not merely a regional issue — it represents a potential shock to the global energy system comparable to or exceeding the 1973 Arab oil embargo. For India, with ~50% of crude imports transiting the strait, the calculus is immediate and existential for its energy security planning.
India's Energy Security Architecture: Import Dependence, Reserves, and Diversification
India is the world's third-largest oil consumer and importer, behind the US and China. It imports approximately 85% of its crude oil requirements, making it highly vulnerable to supply disruptions and price shocks. India's energy security framework has three components: strategic reserves, supplier diversification, and domestic production expansion.
- India's Strategic Petroleum Reserve (SPR): Three underground rock cavern facilities at Visakhapatnam (1.33 MMT), Mangaluru (1.5 MMT), and Padur (2.5 MMT) — total capacity of 5.33 million metric tonnes, sufficient for approximately 9.5 days of the country's needs.
- Indian refineries maintain an additional 10–15 days of crude inventories in tanks and transit.
- Combining SPR and refinery stocks, India has approximately 74 days of buffer against a complete supply cutoff — though this depends on consumption patterns and does not factor in pipeline or refinery constraints.
- India is expanding SPR capacity: plans to add six new strategic reserves targeting a 90-day buffer, aligning with the IEA standard for member countries (though India is not an IEA member, only an association country).
- Supplier diversification: India has rapidly expanded crude sourcing from Russia (now India's largest supplier at ~40% of imports), US, West Africa (Nigeria, Angola), and Latin America (Brazil, Mexico, Argentina from 2025 onwards).
- Despite diversification, the Strait of Hormuz remains the geographic chokepoint: even Russian crude transported via the western route and Gulf crude from Saudi Arabia or UAE must transit Hormuz to reach Indian ports on the west coast.
Connection to this news: India's current inventory buffer of ~74 days means it is not in immediate danger, but a prolonged Hormuz closure would force a structural shift: higher insurance costs, freight premiums, and the need to source more expensive non-Gulf crude at scale — with direct inflationary consequences.
Oil Price Shocks and the Indian Macroeconomy: Historical Patterns and Policy Levers
India has experienced three major oil price shocks in its modern economic history — 1973-74, 1979-80, and 2008 — each of which significantly disrupted the balance of payments, triggered fiscal stress, and contributed to inflationary spirals. The mechanism is straightforward: as a net importer, a rise in crude prices widens the current account deficit (CAD), puts pressure on the rupee, raises fuel subsidy bills, and feeds input cost inflation across manufacturing and transport.
- Every USD 10/barrel increase in crude prices widens India's CAD by approximately 0.4–0.5% of GDP and increases the fuel subsidy burden by approximately Rs 10,000–12,000 crore per year (depending on the pass-through mechanism).
- India's oil import bill is approximately USD 130–140 billion annually at pre-crisis prices; a doubling of crude prices would add USD 130+ billion to the import bill.
- The rupee-dollar exchange rate is highly sensitive to crude shocks: rising oil prices force higher dollar demand for oil purchases, weakening the rupee and further amplifying the cost of oil imports in rupee terms.
- Policy levers available to the government: release SPR stocks, cut excise duty on fuels (as done in November 2021 and May 2022), negotiate emergency supply deals, and redirect subsidy expenditure.
- India's decision to buy Russian crude at a discount post the 2022 Ukraine sanctions demonstrated a strategic willingness to prioritise energy security over geopolitical alignment.
Connection to this news: A sustained Strait of Hormuz disruption would test all three of India's oil price shock response mechanisms simultaneously: SPR adequacy, supplier diversification, and fiscal management — in a context where geopolitical pressure to reduce Russia dependence is already elevated.
