Hormuz disruption will continue until 80 mines blocking route are cleared

What Happened

The Strait of Hormuz remains heavily disrupted despite a memorandum of understanding between the US and Iran. Intertanko marine director Phil Belcher reported that approximately 80 mines laid by Iran in the central traffic separation scheme must be cleared before normal shipping can resume. Vessels are currently using a narrow southern route near the Omani coast, which Belcher likened to a highway's hard shoulder, risking groundings and collisions. The danger is compounded by Iranian signal jamming that has disabled ships' navigation systems, effectively blinding them. Nearly 600 vessels are still anchored in the Gulf since February. While the US-Iran memorandum requires toll-free passage for 60 days and full traffic restoration within 30 days, Iran has indicated it will charge maritime fees thereafter, drawing condemnation from Hapag-Lloyd and concerns over international law and precedent.

Key Actors

Why It Matters

The Strait of Hormuz handles about 20% of global oil trade, and prolonged disruption threatens energy markets and supply chains. The 80 mines and navigational hazards could delay normalization for months, risking a repeat of the Ever Given blockage. Iran's toll plan challenges the international law of transit passage and could set a dangerous precedent for strategic waterways like the Malacca and Taiwan straits, raising geopolitical tensions beyond the immediate region.

Watch For

Monitor mine clearance progress and whether Iran meets the 30-day deadline for full traffic restoration. Watch for Iran's implementation of shipping tolls after the 60-day period and any legal or diplomatic countermeasures. Track collision or grounding incidents in the narrow southern route amid signal jamming. Also observe whether the toll dispute escalates into broader challenges to freedom of navigation in other chokepoints.
