Strait of Hormuz Transit Collapses to Eight Vessels as US-Iran Standoff Deepens
Only eight vessels transited the Strait of Hormuz on August 12, 2026, down from a pre-war baseline of 130 to 140 ships, according to Reuters data cited by Al Jazeera. The figure represents a further contraction from the six vessels recorded on Monday and a 10-day average of roughly 11, marking a new low for the critical maritime chokepoint since the conflict began.
US President Donald Trump used a Truth Social post to claim that the United States has 'total control' over the strait, reiterating an assertion made to reporters the previous day. Trump described the ongoing US blockade of Iranian ports as 'A WALL OF STEEL' and stated that Iran 'can do nothing about it.' He also said the US would charge other ships for safe passage through the strait, a waterway through which roughly a fifth of global oil historically flows Al Jazeera.
Iran's conditions for reopening the strait remain unchanged. On August 10, Iran said it will not allow full traffic to resume until the US lifts its naval blockade, lifts sanctions, unfreezes Iranian assets, and pays compensation for war damage, including war reparations. Iran's leadership believes that sooner or later the United States will have to accede to their control over the strait AP News.
The broader context here is a conflict now in its sixth month, with multiple diplomatic attempts having collapsed. The US and Israel launched the war with Iran on February 28. In April, the White House announced a ceasefire under what it called 'Operation Epic Fury,' but by mid-July a Memorandum of Understanding signed in June had dissolved, with both sides renewing attacks. Iran tightened its grip on the strait throughout April, warning mariners that the route was closed, and by late July declared it remained in control and was not seeking talks after Trump halted bombing.
Meanwhile, Iran has pursued separate talks with Oman on the future management of the strait. Those discussions do not include Washington and have largely paused wider US-Iran peace negotiations. A proposed Hormuz deal reported on August 5 would give Iran control of inbound traffic through the strait, which sources described as a major concession to Tehran.
The maritime picture is growing more complex on a second front. On August 11, a US Navy military helicopter struck a Panama-flagged cargo vessel in the strait. The same day, Yemen-based Houthis opened a new front in the war with attacks on vessels in the Bab al-Mandab Strait, killing six people in an attack on an Egyptian-owned ship, the first deaths from such an attack.
Shipping data paints a grim trajectory. Kpler reported that Hormuz crossings fell 70 percent post-truce, with 90 percent of remaining traffic now using an unrecognised Iranian route. The firm estimated that recovery to normal traffic levels will not come until 2027. Windward had reported as early as March 8 that GPS and AIS interference in the region intensified sharply, affecting more than 1,650 vessels. The WTO Strait of Hormuz Trade Tracker noted a cautious restart in late June following the MOU signing, but that brief window has since closed.
The standoff leaves commercial shipping caught between a US-enforced blockade and an Iranian government demanding full sanctions relief and reparations before restoring transit. With the Houthis now active in the Bab al-Mandab as well, vessels face simultaneous disruption at both ends of the Arabian Peninsula. The parties appear locked into maximalist positions: Washington asserts total military control, Tehran conditions any reopening on comprehensive economic and political concessions, and the diplomatic track has fragmented into bilateral channels that exclude the principal belligerent.
