Strait of Hormuz Shipping Crisis: Global Energy Security at a Chokepoint
The Strait of Hormuz has been the site of an unprecedented dual blockade in 2026 — the United States declared a naval blockade of Iranian ports from April 13, 2026, while Iran's Revolutionary Guard Corps (IRGC) simultaneously issued warnings forbidding passage through the strait, laid sea mines, and attacked commercial vessels — creating a situation where both entry and exit points are under rival military control.
Before the crisis, the Strait of Hormuz handled approximately 20 million barrels of oil per day — about 25% of global seaborne oil trade and one-fifth of global LNG trade. Tanker traffic through the strait has dropped by more than 95% since late February 2026, triggering what the International Energy Agency (IEA) has described as "the greatest global energy security challenge in history."
Iran captured two container ships attempting to exit the Persian Gulf on April 22, 2026, and at least three tankers have been struck near the strait, including one set ablaze off Oman. Vessels now require approval from both the US Navy and Iranian authorities to transit — a practical impossibility in current conditions.
India faces a compounded energy squeeze: its US waiver allowing purchase of Russian crude expired on April 11, 2026, and its first Iranian oil shipment in seven years is now blocked, creating what analysts describe as a "mounting supply squeeze."
To manage domestic fuel prices, the Indian government reduced excise duties on petrol and diesel by ₹10 per litre in late March 2026, marking a significant fiscal intervention.
Strait of Hormuz: Geography and Strategic Significance
The Strait of Hormuz is a narrow waterway located between Iran to the north and the Musandam Peninsula (shared by Oman and the UAE) to the south, connecting the Persian Gulf to the Gulf of Oman and the Arabian Sea. It is approximately 167 km long and narrows to about 39 km at its narrowest point, with navigable channels of only a few kilometres wide.
The Hormuz crisis demonstrates how a single geographic bottleneck can hold the global economy hostage. India's dependence on Persian Gulf crude — running through this strait — converts the geopolitics of West Asia directly into India's domestic fuel prices and balance of payments.
India's Oil Import Dependence and Energy Security
India is the world's third-largest oil importer and the third-largest oil consumer, importing over 85% of its crude oil requirements. Crude oil and petroleum products constitute the single largest component of India's import bill, making oil price shocks and supply disruptions a direct macroeconomic risk.
India's energy security vulnerability is starkly exposed by the Hormuz crisis — the simultaneous loss of Iranian barrels, constrained Russian crude access, and blocked transit routes through Hormuz constitute a multi-front supply shock with direct inflationary and fiscal implications.
UNCLOS and Freedom of Navigation
The United Nations Convention on the Law of the Sea (UNCLOS), adopted in 1982 and in force from 1994, is the comprehensive legal framework governing maritime zones, navigation rights, and ocean resources. India ratified UNCLOS in 1995.
The Hormuz crisis represents a live stress test of the international law of the sea — specifically whether UNCLOS's transit passage guarantees can be enforced when major naval powers are in direct conflict over the same waterway.
Chokepoints and India's Maritime Energy Strategy
Maritime chokepoints are narrow straits or canals through which a disproportionate share of global trade flows, making them strategic vulnerabilities. Key global chokepoints include: Strait of Hormuz (Persian Gulf oil/LNG), Strait of Malacca (Indo-Pacific trade), Bab-el-Mandeb (Red Sea/Suez access), Suez Canal (Europe-Asia), and Panama Canal (Atlantic-Pacific).
Key Details
- India's geographic position makes it dependent on multiple chokepoints: Hormuz for energy imports from the Gulf, Bab-el-Mandeb and Suez for trade with Europe.
- The Houthi attacks in the Red Sea (2023-2025) disrupted Bab-el-Mandeb passage and increased shipping costs; the Hormuz crisis in 2026 compounds this pattern of chokepoint fragility.
- India's Sagarmala Programme and Project Mausam reflect efforts to build maritime connectivity, but these address commercial infrastructure — not energy supply chain resilience.
- India's Strategic Petroleum Reserve (SPR) expansion is ongoing; the government has proposed adding commercial SPR capacity, including a planned facility at Chandikhol (Odisha) and a private SPR framework to augment state-owned caverns.
Back-to-back disruptions at Bab-el-Mandeb (2023-25) and Hormuz (2026) underscore that India needs a comprehensive maritime energy security strategy — combining SPR expansion, supply diversification beyond the Gulf, and diplomatic engagement with both West Asian and alternative supplier states.
- Strait of Hormuz daily oil transit (2025): approximately 20 million barrels — about 34% of global crude oil trade
- LNG transit through Hormuz: approximately 20% of global LNG trade (primarily Qatar)
- India's share of Hormuz crude oil flows (2024): approximately 14.7% — second largest Asian destination
- India's crude oil import dependence: over 85% of domestic requirements
- India's daily crude import volume: approximately 5.5 million barrels per day
- India's net oil imports as % of GDP: approximately 3.5%
- India's Strategic Petroleum Reserve capacity: approximately 5.33 million metric tonnes (Visakhapatnam, Mangaluru, Padur)
- Indian SPR import cover: approximately 9-10 days
- Bypass pipeline capacity (Saudi + UAE): 3.5–5.5 mb/d — insufficient to replace Hormuz flows
- India's excise duty reduction (March 2026): ₹10 per litre on petrol and diesel
- UNCLOS adopted: 1982; in force: 1994; India ratified: 1995
- UNCLOS Article 37: guarantees right of transit passage through international straits
- Drop in Hormuz tanker traffic since late February 2026: over 95%
- India's supplier diversification (March 2026): crude sourced from approximately 40 countries
