Traffic through the Strait of Hormuz has fallen sharply since Wednesday, especially through the UN-backed Omani route, analysts said, after vessels were attacked earlier this week and as the United States and Iran traded renewed strikes.
Flows through the strategic waterway reached their highest levels since the start of the war after a truce was agreed between the two sides in mid-June, although they remained at around a third of peacetime levels.
However, the recovery appears to have stalled -- just six commodity tankers have crossed so far on Thursday, and 21 such vessels transited the waterway on Wednesday, according to Kpler data as of 1430 GMT.
The only day with less traffic since the US-Iran truce was on June 28, when just 19 commodities vessels crossed a day after a tanker was attacked off Oman.
US President Donald Trump declared the ceasefire over on Wednesday but left the door open to more talks, and analysts said that the path to lasting peace was never going to be straightforward.
