What Happened
- Iran's Islamic Revolutionary Guard Corps (IRGC) conducted live-fire military drills in the Strait of Hormuz on February 17, 2026, partially closing parts of the waterway for several hours.
- The exercise, named "Smart Control of the Strait of Hormuz," involved live missile tests, with missiles launched from inside Iran and along its coast striking targets in the Strait.
- The drills coincided with the resumption of indirect US-Iran nuclear talks in Geneva, Switzerland, appearing designed to signal Iran's ability to disrupt maritime traffic as leverage during negotiations.
- This was the first time Iran shut parts of the Strait since US President Donald Trump threatened Tehran with military action in January 2026.
- Iran also announced upcoming joint naval drills with Russia in the Gulf of Oman, raising fears of accidental escalation.

Strait of Hormuz: Geography and Global Energy Security
The Strait of Hormuz, located between Iran and Oman, connects the Persian Gulf with the Gulf of Oman and the Arabian Sea. It is the world's most important oil transit chokepoint.
- Approximately 20 million barrels per day of oil transit through the Strait, accounting for about 25% of global seaborne oil trade and roughly one-fifth of global oil and petroleum product consumption.
- About 80% of crude oil transiting the Strait is destined for Asian markets, with China, India, South Korea, and Japan being the top importers.
- The Strait is approximately 33 km wide at its narrowest point, with shipping lanes only about 3 km wide in each direction, separated by a 3 km buffer zone.
- Bypass options are extremely limited. Only Saudi Arabia and the UAE have minor pipeline routes that avoid the Strait, while Iran relies exclusively on Gulf terminals for exports.
- Any sustained disruption would have severe consequences for global oil markets and energy prices.
Connection to this news: Iran's partial closure demonstrates its strategic ability to disrupt this critical chokepoint, directly affecting India's energy security given that India imports a significant share of its crude oil through the Strait of Hormuz.
Iran Nuclear Programme and the JCPOA
Iran's nuclear programme has been a source of international tension since 2002 when the existence of undeclared nuclear facilities at Natanz and Arak was revealed.
- The Joint Comprehensive Plan of Action (JCPOA) was signed in 2015 between Iran and the P5+1 (US, UK, France, Russia, China, plus Germany), placing limits on Iran's uranium enrichment in exchange for sanctions relief.
- The US withdrew from the JCPOA in May 2018 under the Trump administration and reimposed sanctions.
- Iran subsequently began exceeding JCPOA limits, enriching uranium to 60% purity (weapons-grade is approximately 90%).
- The International Atomic Energy Agency (IAEA) monitors Iran's nuclear activities but has reported reduced access since 2021.
- Indirect talks between the US and Iran have continued intermittently, with the current Geneva round representing a fresh diplomatic attempt.
Connection to this news: The military drills during ongoing Geneva talks illustrate Iran's dual-track strategy of maintaining military deterrence while engaging diplomatically, complicating international efforts to resolve the nuclear standoff.
India's Energy Security and West Asian Dependence
India is the world's third-largest oil consumer and imports over 85% of its crude oil requirements. West Asia (the Middle East) accounts for a dominant share of these imports.
- Iraq, Saudi Arabia, and the UAE are among India's top crude oil suppliers, all of whom export through the Strait of Hormuz.
- India has pursued diversification through agreements with Russia, the US, and African nations, but West Asian dependence remains structurally high.
- India maintains a Strategic Petroleum Reserve (SPR) programme with facilities at Visakhapatnam (1.33 MMT), Mangaluru (1.5 MMT), and Padur (2.5 MMT), totalling 5.33 MMT under Phase I.
- Phase II of the SPR programme envisages additional capacity at Chandikhol (Odisha) and Padur (Karnataka).
Connection to this news: Any disruption in the Strait of Hormuz directly threatens India's energy supply lines, underscoring the importance of India's strategic petroleum reserves and diversification efforts.
