Trump’s 18-Hour Iran Ultimatum: Strait of Hormuz, Nuclear Showdown & India’s Energy Security

Cargo ship in Arabian Gulf near Strait of Hormuz

CURRENT AFFAIRS | MARCH 23, 2026 | CLAT GK + LEGAL

US President Donald Trump issued Iran an 18-hour ultimatum — accept a nuclear deal or face military strikes. Iran responded by threatening to close the Strait of Hormuz, the world’s most critical oil shipping chokepoint carrying 20% of global oil supply. India’s Cabinet Committee on Security (CCS), chaired by PM Modi, convened urgently — with a team of Ministers and Secretaries tasked to prepare India’s contingency plan.

Why CLAT 2027 Aspirants Must Know This

This crisis spans GK (international current affairs) and Legal Reasoning (international maritime law, UNCLOS, constitutional machinery). CLAT passages regularly test knowledge of geopolitical flashpoints, India’s energy security, international organisations (IAEA), and how India’s constitutional framework responds to security crises. The Strait of Hormuz has appeared in CLAT GK sections multiple times.

Key Facts at a Glance

  • Trump issued Iran an 18-hour ultimatum to accept nuclear deal terms or face strikes
  • Iran warned of full closure of the Strait of Hormuz if attacked by the US
  • Strait of Hormuz is ~33 km wide at its narrowest; located between Iran and Oman
  • ~20% of global oil trade (17–18 million barrels/day) passes through the Strait
  • India imports ~60% of its crude oil from Gulf nations — highly vulnerable to any closure
  • India’s CCS (Cabinet Committee on Security) chaired by PM Modi convened urgently
  • The standoff stems from Trump’s “maximum pressure” campaign — JCPOA was abandoned in 2018
  • India’s Strategic Petroleum Reserve (SPR) holds ~9.5 million metric tonnes at Vizag, Mangalore, Padur
  • Iran’s nuclear enrichment is monitored by the IAEA (HQ: Vienna, Austria)
  • LPG prices globally already under severe stress due to the West Asia conflict
