Key Vessel Movements
In the 24-hour period to May 21, Chinese ship Zhong Gu Nan Chang and ten vessels crossed the Strait of Hormuz. VLCC Yuan Gui Yang (COSCO, chartered by Unipec) carried 2 million barrels of Iraqi Basrah crude; Hong Kong-flagged VLCC Ocean Lily (Sinochem) held 1 million barrels each of Qatari al-Shaheen and Iraqi Basrah crude; and South Korean VLCC Universal Winner moved about 6 million barrels.
Data & Statistics
Pre-war traffic averaged 125–140 vessels daily; recent counts are about 10, leaving 20,000 seafarers stranded. Iran announced 26 transits on May 20; data showed 10. Since March 1, 19 non-Iranian tankers have entered and exited, with 100 stuck. 47 ships operate in “dark mode.” Brent fell to $110.16 per barrel.
Official Statements & Responses
Joint Maritime Center said risk high. Iran said ships had authorization. President Trump and Vice President Vance said negotiations to end the war were progressing “very quickly.” Shipping groups warned “hundreds of vessels remain unable to transit.” A UN report linked the blockage to a downgrade in growth forecasts.
Criticism & Opposition
Ship broker Fearnleys lamented, saying “we need the waterways to open, that’s for sure, both for the shipping industry and no less so for the world economy.” Saxo Bank analyst Ole Hansen warned low oil prices mask the supply shock, attributing price stability to demand destruction rather than restored supply.
Conflicting Reports & Gaps
Iran claimed 26 vessels transited on May 20, yet satellite and Kpler data recorded only 10. Some sources say Chinese tankers crossed without paying tolls, while Iranian statements give no detail. Reported oil volumes vary between 4 million and 6 million barrels, reflecting differing cargo accounting.
Why It Matters
The limited flow of Chinese supertankers suggests a possible easing of Iran’s control over the chokepoint, which could affect global oil supply, market pricing, and the strategic calculations of Hormuz-dependent nations. Ongoing restrictions keep roughly 20 percent of daily oil flows at risk, influencing inventories and prompting UN calls for strategic reserve releases.

What’s Next
Negotiations mediated by Pakistan remain at an impasse, while Iran has pledged to increase authorized transits. Shipping firms expect further Chinese and South Korean VLCC attempts in the coming weeks, contingent on security assessments and the outcome of U.S.–Iran talks. Ongoing monitoring of vessel movements and price trends will show whether the limited flow develops into sustained traffic.
