Hormuz Strait Traffic Slows as Shipowners Avoid Waterway Amid Unclear Reopening Signals

BLUFSustained diversion by major Chinese carriers and absent insurer guarantees make a return to pre-crisis Hormuz transit volumes very unlikely within 30 days, regardless of diplomatic rhetoric.

Kpler tracking data showed six commodity vessels crossed the Strait of Hormuz on Tuesday, down from nine the day before and below the 10-day daily average of 11, as most shipowners avoided the waterway given unclear signals on its status following a blockade during the Iran war 12. Inbound traffic included an empty very large crude carrier that followed the Omani side of the strait plus a medium-range and an intermediate tanker, while two medium-range fuel tankers and a post-Panamax vessel exited 1. On Tuesday President Trump said no talks were underway with Iran and asserted the strait remained open, contradicting Iran's position that it stays closed to shipping 13. Tanker tracker Vortexa and a ship broker reported that two Chinese shipping giants, which together carried half of China's Middle Eastern oil imports before the war, have kept tankers out of both the Strait of Hormuz and Bab al-Mandeb since late July 12. At Bab el-Mandeb, where Yemen's Houthis declared a naval blockade of Saudi Arabia on July 20, Kpler recorded 30 weekend vessel transits, up from 19 the prior week, with no tracked Saudi oil shipments 1. The strait handled a fifth of the world's crude oil and liquefied natural gas shipments before the war 1.

Analysis
Hormuz transit volumes are very unlikely to rebound to the prior 10-day average of 11 vessels daily within 30 days, as shipowners price continued ambiguity over the strait's legal and security status rather than any specific new threat, compounded by the UAE's concurrent trade embargo constraining Tehran's shipping and import routes. The two Chinese carriers' month-long diversion points to a sustained commercial hedge, though the dip may instead reflect risk management by those two exposed carriers rather than a market-wide verdict that the strait is unsafe. Confidence is low, given single-day traffic counts drawn from a single Reuters wire with no independent corroboration or insurer and charter-rate data. A rebound to the 11-vessel baseline would let insurers and CENTCOM plan around lowered risk premiums, while continued suppression pushes Washington toward concrete security guarantees beyond Trump's rhetorical assurance that the strait remains open.
