Situation
The Strait of Hormuz remains under extreme operational stress, with the Hormuz Index state composite fixed at 92 (extreme) and physical transit deviation continuing as the dominant pressure driver. PortWatch's most recently published figure, covering 2026-06-14, recorded 0 vessel transits through the strait against a pre-crisis baseline of 94 per day; that number is four days old given PortWatch's weekly Tuesday publication cycle and should not be read as a real-time measure. Separately, an independent scraper tracking Gulf-port arrivals counted 260 vessels in the most recent 24-hour window, a figure reflecting different methodology and scope and not directly comparable to the PortWatch transit count. Against that backdrop, Brent crude fell -21.02% over the past 24 hours, a move that markets appear to be pricing off two converging signals: a Times of India report that a Qatar LNG tanker has sailed for Hormuz as Middle East conditions improve, and repeated iHeart Radio syndication of a story indicating Trump views the Iran deal timeline as flexible. The 30-day Escalation Forecast sits at 52 (elevated), down 3 points, with Polymarket closure probability now its top contributor. The gap between the state reading of 92 and the forecast reading of 52 is meaningful; physical conditions on the water remain extreme even as financial markets and prediction markets price in de-escalation. With 416 vessels anchored or stopped and 18 indexed events in the past 24 hours, that optimism has not yet translated into normalized transit flow.
