Traffic through the Strait of Hormuz has increased in recent days, but shipowners remain cautious following an attack on a vessel in the Gulf of Oman, reported Texas-based OilPrice.

Two crude tankers were seen moving out of the strait while four empty supertankers were inbound near Oman, according to Bloomberg vessel-tracking data. The attack on the containership Ever Lovely prompted some shipowners to delay transits.

At least one Asia-based shipping company reversed plans to send vessels through the Strait and instructed staff to remain in place, Bloomberg reported. Shipowners and captains said they were waiting for clarity on safety conditions.

The UN's International Maritime Organization (IMO) paused its evacuation plan for stranded vessels after the attack, which did not occur under its framework. Secretary-General Arsenio Dominguez stated that the pause was needed to ensure navigational safety.

Despite the incident, millions of barrels of oil moved through the Strait over the past week, raising hopes that supply disruptions may ease. Oil prices were heading for a weekly loss amid a tentative recovery in traffic.

Uncertainty persists, however, with Iran's Islamic Revolutionary Guard Corps claiming vessels in the southern corridor had been ordered to turn back. Maritime intelligence firm Windward identified five ships showing behavior consistent with the claim.
