What Happened
- Iran's effective closure of the Strait of Hormuz since late February 2026 has triggered what analysts are calling the largest disruption to the global energy supply since the 1970s oil crisis.
- Brent crude oil prices crossed $100 per barrel on March 8, 2026 — for the first time in four years — and peaked at $126 per barrel; Asian spot LNG prices surged from $10/MMBtu to $24–25/MMBtu, a 140–150% spike.
- Exports worth up to $1.2 trillion per year could be affected if the blockade persists, according to UNCTAD (United Nations Conference on Trade and Development).
- Major container shipping companies including Maersk, CMA CGM, and Hapag-Lloyd suspended transits through the strait and related routes.
- OPEC+ pledged to increase oil output by 206,000 barrels per day; the IEA took the unprecedented step of authorising the release of 400 million barrels from member states' strategic petroleum reserves.
- South Asia — particularly India, Pakistan, and Bangladesh — faces the most acute disruption for LNG, given heavy dependence on Qatar and the UAE, both of which export exclusively through the strait.
- Beyond energy, supply chains for fertilisers, pharmaceuticals, electronics, rubber, and agricultural commodities face disruption, threatening food security in import-dependent countries.

Chokepoints and Global Supply Chain Vulnerability
A maritime chokepoint is a narrow waterway through which a disproportionately large share of global trade must pass, making it a single point of failure for the global economy. The world's major chokepoints include the Strait of Hormuz, the Strait of Malacca, the Suez Canal, the Bab-el-Mandeb Strait, and the Strait of Gibraltar.
- The Strait of Hormuz handles approximately 20% of global seaborne oil and 20% of global LNG trade — about 20 million barrels of oil per day.
- The Strait of Malacca (between Malaysia, Singapore, and Indonesia) carries about 40% of global trade by volume, making it the world's busiest chokepoint.
- Unlike the Suez Canal or Panama Canal (which have alternative routes, albeit longer), the Strait of Hormuz has no viable bypass for Persian Gulf oil exports — the Saudi Arabia-UAE Abqaiq–Yanbu pipeline and the UAE's Habshan–Fujairah pipeline together can carry only about 6.5 million barrels per day, far below the strait's normal throughput.
- The 2021 Ever Given incident in the Suez Canal demonstrated how even a temporary chokepoint blockage can cascade through global supply chains within days.
Connection to this news: The Hormuz blockade illustrates the inherent fragility of a supply chain architecture built around a single narrow strait — a fragility that is now inflicting cascading economic damage across continents.
India's Energy Security and LNG Import Dependence
India is the world's third-largest oil importer and consumer, meeting over 85% of its crude oil needs through imports. Natural gas accounts for about 6% of India's primary energy mix, with roughly 50% of its natural gas requirement sourced from imported LNG. India's LNG supply chain is critically concentrated in the Gulf region.
- Qatar supplies approximately 47% of India's LNG imports (about 11.3 MMT out of 27.8 MMT total in 2024).
- UAE accounts for 13.47% and the US for 10.51% of India's LNG imports.
- Nearly 60% of India's total LNG imports transit the Strait of Hormuz — making the blockade an acute threat to India's gas supply security.
- India's three underground Strategic Petroleum Reserves (SPRs) at Visakhapatnam (1.33 MMT), Mangaluru (1.5 MMT), and Padur (2.5 MMT) provide approximately 9.5 days of crude oil coverage — well below the IEA's recommended 90-day standard.
- India is an IEA associate member (not full member), meaning it has no binding obligation to participate in coordinated reserve releases.
- An Israeli missile strike on Iran's South Pars gas fields triggered Iranian retaliation against Qatar's Ras Laffan LNG hub, reducing Qatar's LNG output capacity by approximately 17% for several years.
Connection to this news: India's heavy LNG dependence on Qatar — which exports exclusively through the Hormuz strait — places the country among the most directly affected nations from the blockade, with direct implications for industrial energy costs, fertiliser supply, and the power sector.
The 1973 Oil Crisis: Historical Precedent for Energy Weaponisation
The 1973 Oil Crisis (also called the OPEC Oil Embargo) erupted when Arab members of OPEC embargoed oil exports to nations supporting Israel in the Yom Kippur War, including the US, UK, Japan, and the Netherlands. It caused oil prices to quadruple from ~$3 to ~$12 per barrel, triggered stagflation in Western economies, and permanently reshaped global energy policy.
- The crisis led directly to the creation of the International Energy Agency (IEA) in 1974, specifically to coordinate emergency oil stockpiling and release among developed nations.
- It accelerated energy diversification, energy efficiency mandates, and the development of North Sea and Alaskan oil fields by Western powers.
- The strategic petroleum reserve (SPR) concept was born from the 1973 crisis — the US SPR, established in 1975, currently holds around 350 million barrels.
- The 1973 crisis lasted about six months; the 2026 Hormuz crisis, if prolonged, could exceed its economic impact because of the far greater volume of trade now dependent on the strait.
- UPSC has tested knowledge of the 1973 oil crisis in context of energy security, India's import dependence, and the IEA's establishment.
Connection to this news: The 2026 Hormuz blockade is being compared to the 1973 crisis in its potential economic impact — with the IEA's unprecedented 400-million-barrel reserve release echoing exactly the emergency mechanisms created in response to 1973.
