  • U.S. allies are skeptical of Trump's claims that Iranian mines have been fully cleared from the waterway, contradicting his Wednesday statement calling Hormuz 'a functioning strait'
  • Iran's Foreign Minister called on the UN to condemn U.S. 'economic terrorism' and warned the strait won't fully reopen until the U.S. fulfills commitments under a lapsed June interim peace deal

Summary: Strait of Hormuz Tanker Attack Tests Security Claims

An oil tanker caught fire Tuesday after being struck by an unidentified projectile in the Strait of Hormuz, according to the UK Maritime Trade Operations agency. The incident occurred off Oman's coast; all crew members were reported safe and the fire was extinguished. This follows another attack last week that killed a crew member.

Key Figures:

  • Only 5 ships made confirmed crossings Tuesday, down from 7 the previous day
  • Pre-war traffic exceeded 130 vessels daily, according to tracking firm Kpler
  • All five crossings used Iran's designated unilateral route

Market Implications:

The attacks directly contradict President Trump's Wednesday statement calling Hormuz "a functioning strait" with mines fully cleared. U.S. allies have reportedly challenged these claims, expressing skepticism about complete mine removal. Traffic through the vital energy corridor remains significantly below pre-war levels despite U.S. escort efforts along the Omani side.

Diplomatic Context:

Iran and Oman are negotiating to restore safer passage, but Iran's Deputy Foreign Minister warned the waterway won't fully reopen until the U.S. fulfills commitments under a June interim peace deal framework that has since lapsed. The U.S. maintains a naval blockade against Iranian ships.

Iran's Foreign Minister Abbas Araghchi called on the UN to condemn U.S. "economic terrorism," arguing the organization bears legal and moral responsibility to denounce sanctions.

The ongoing instability threatens global energy supply chains, as the Strait of Hormuz is a critical chokepoint for oil transit. Continued attacks and reduced traffic signal persistent maritime security risks despite official assurances.
