Iran's security apparatus is rejecting US claims that oil keeps flowing freely through the Strait of Hormuz, insisting the waterway remains closed on Tehran's terms. Daily shipping traffic through the channel, which normally carries a fifth of the world's oil, has collapsed since hostilities escalated earlier this year.
Daily shipping traffic through the Strait of Hormuz has plummeted to under 20 vessels as of late August 2026, down from an average of around 130 before hostilities escalated — an 85% drop in transit volume. Roughly 20% of the world's petroleum passes through this 21-mile-wide channel on a normal day.
Two governments, two realities
US Central Command reported facilitating the passage of over 1,500 commercial vessels and the movement of 750 million barrels of oil in August 2026 alone. Iran's security sources call those figures false, however, maintaining that Tehran continues to enforce its closure of the strait.
How the standoff escalated
The current standoff traces back to a broader US-Iran conflict that escalated sharply in February 2026. Then, in May 2026, Tehran established the Persian Gulf Strait Authority, a new regulatory body that requires passage permits for any vessel transiting the strait.
A brief diplomatic window opened on June 17, 2026, when the two sides signed a memorandum of understanding allowing safe passage without fees for 60 days. A resurgence of hostilities in July derailed the arrangement, and Iranian officials have since reiterated that the strait will remain closed until the US lifts what Tehran describes as a blockade.
Stakes for oil markets
The strait facilitates about one-fifth of global oil and LNG exports from Saudi Arabia, Iraq, Kuwait, the UAE, and Qatar. The disruption has driven up insurance premiums and pushed some shippers toward a shadow fleet, while the US has promoted a southern corridor alternative.
The ripple effects extend beyond oil markets: natural gas shipments, petrochemical feedstocks, and container traffic all flow through the same waterway.
