COSCO Shipping (1919 HK) and CMES have reportedly stopped sending oil tankers through the Strait of Hormuz and Bab al-Mandeb, sources suggest

Carrier-led withdrawals from chokepoints have historically been a leading indicator of freight stress rather than a consequence of it: when major owners pull tonnage from Hormuz or the Bab al-Mandeb corridor, war-risk premia and tanker rates have tended to reprice before crude benchmarks do, since the first transmission channel is insurance and available supply of willing hulls, not lost barrels. The composition here matters: Chinese state-linked owners have on past occasions continued transits when Western carriers diverted, so a reported halt from this cohort would mark an escalation in perceived risk rather than routine caution. A pause in transit is also different from a closure of the strait itself; the former raises voyage costs and lengthens effective supply chains via rerouting and queueing, the latter is a physical supply event, and markets have historically treated the two very differently. The distinction worth watching is whether this proves temporary and insurance-driven or hardens into a sustained rerouting pattern, and whether other national fleets and charterers follow. Follow-ons include any confirmation or denial from the companies, movement in war-risk cover for Gulf and Red Sea loadings, and VLCC rate prints on affected routes. As a sources-based report, it sits below official confirmation in the usual hierarchy of such headlines.
