Situation

The Strait of Hormuz is operating at roughly 2% of its pre-crisis throughput, with just 2 vessel transits recorded today against the IMF PortWatch baseline of 95 per day — a figure that now anchors every pricing conversation in the oil and shipping markets. Brent settled at $116.73, having gained +2.43% in the past 24 hours, while WTI tracked at $112.25; Wood Mackenzie's publicly circulated warning that a prolonged closure could push prices toward $200 per barrel and trigger a global recession is no longer treated as a tail-risk scenario by the desk community. The operational picture is sharply contested: the IRGC Navy announced it coordinated passage for 26 ships through the strait in the 24 hours ending noon on May 20, a figure Iran is using to assert de facto traffic-control authority over the waterway. Meanwhile, U.S. Marines boarded and redirected an Iranian-flagged tanker in the Gulf of Oman, signalling continued American enforcement of its maritime blockade. The global shipping industry issued new transit guidance warning that technical openness does not equal operational safety. On the diplomatic track, the IAEA director general announced travel to the Persian Gulf region to pursue a nuclear safety pathway, while a fragile Gaza ceasefire and continued Lebanon-Israel skirmishing keep the broader regional risk premium elevated. Twelve discrete events were indexed across the crisis tracker in the past 24 hours.
