Commercial shipping through the Strait of Hormuz has been severely constrained since hostilities in the region began on 28 February 2026. At the low point in early March, tanker traffic in the strait effectively ceased, and by late April the International Maritime Organization counted roughly 2,000 ships and 20,000 mariners held up inside the Persian Gulf.
A memorandum signed on 17 June was intended to end the blockade, and the Joint Maritime Information Center downgraded its Hormuz threat assessment from critical to severe on 7 June after a run of safe transits along the southern corridor near the Omani coast. The recovery is real but uneven: IMF PortWatch data shows 27 vessels transiting on 28 June — about 32% of the typical 84 per day — while on 7 July two tankers were struck by projectiles inside the strait, including an LNG carrier that suffered an engine-room fire. Residual sea mines remain a live constraint, with clearance operations ongoing since April.
