Strait of Hormuz Disruption: India's Energy Security Exposed
Escalating military conflict between US-Israel and Iran has raised alarm about potential disruption to the Strait of Hormuz, the world's most critical oil chokepoint.
Iran has historically threatened to close the strait in response to military pressure, and renewed US-Israel strikes in February-March 2026 have brought these threats back to the forefront.
Nearly 50% of India's crude oil imports transit through the strait, making a closure an acute threat to India's energy supply chain.
India has built certain buffers — Strategic Petroleum Reserves (SPR), diversified supplier base including Russian crude, and currency swap/barter mechanisms with some suppliers — but analysts argue these are insufficient for a prolonged blockade.
Global crude oil prices spiked sharply following the escalation, with potential inflationary consequences for the Indian economy.
The Strait of Hormuz: Geography and Strategic Significance
The Strait of Hormuz is a narrow waterway located between Iran to the north and Oman and the UAE to the south, connecting the Persian Gulf to the Gulf of Oman and the Arabian Sea. At its narrowest point, the strait is approximately 33 km (21 miles) wide, with shipping lanes just 3 km wide in each direction.
India's exposure to any Strait of Hormuz disruption is among the highest of any major economy, making the Israel-Iran conflict directly relevant to India's energy security calculus.
India's Strategic Petroleum Reserves (SPR)
India's Strategic Petroleum Reserves are underground storage facilities for crude oil maintained as a buffer against supply shocks. They are managed by Indian Strategic Petroleum Reserves Limited (ISPRL), a wholly owned subsidiary of the Oil Industry Development Board (OIDB) under the Ministry of Petroleum and Natural Gas.
India's SPR provides a limited buffer of approximately 9-10 days, making it insufficient for an extended Strait of Hormuz disruption. This structural vulnerability is the "firewall" that the current conflict threatens to overwhelm.
India's Crude Oil Import Dependence
India imports approximately 85% of its crude oil requirements, making it the world's third-largest oil importer and consumer. This structural import dependence is the central vulnerability in any West Asia disruption scenario.
The Israel-Iran conflict directly threatens India's primary oil supply corridor. Even a partial or temporary disruption would force India to pay war-risk premiums, seek expensive alternative routing, and draw down its limited SPR, with cascading macroeconomic effects.
