Strait of Hormuz traffic slumps as oil rises and ASEAN warns of fallout

Brent traded roughly between $89 and $91, briefly touching $91.63, as renewed U.S.-Iran tensions and shipping risks in the Strait of Hormuz cut vessel movements and raised concerns over trade, supply and energy security.

Fact Check
Every element of the claim is corroborated by multiple credible primary news sources citing Lloyd's List Intelligence and Kpler data. CNBC confirms traffic slumped after the U.S. blockade took effect July 15, 2026, with a 66% weekly drop — consistent with 'three-week low.' Fortune confirms attacks, mines, and transit dangers keeping operators sidelined. Both Fortune and Reuters independently confirm the new Houthi naval blockade threat announced July 20, 2026, adding pressure on Middle East oil routes. The claim aligns closely with reporting from all three sources.

Summary

Vessel traffic through the Strait of Hormuz has fallen sharply amid renewed U.S.-Iran fighting, tanker attack reports and mine risks, lifting oil prices and reviving fears of broader supply disruption. Shipping data from multiple providers showed steep declines in crossings, while Brent traded roughly between $89 and $91, briefly reaching $91.63, and WTI remained in the mid-$84 range. Analysts warned prolonged disruption could push oil toward $100 a barrel. ASEAN ministers meeting in Manila said they were "deeply concerned" that the war on Iran and blockades affecting key Middle East shipping lanes were threatening Southeast Asia's trade and energy security.
