Commercial shipping activity through the Strait of Hormuz has begun to recover after the United States and Iran implemented an agreement aimed at restoring safe passage through one of the world’s most critical energy corridors.

According to maritime intelligence firm Kpler, at least 20 oil tankers crossed the Strait of Hormuz after the reopening measures took effect. Tanker movements on Thursday reached their highest level since June 2, indicating growing confidence among shipping companies following weeks of disruption.

A total of 25 vessels, including oil tankers, cargo ships, and container vessels, transited the strait on Thursday. However, traffic remains below pre-conflict levels, when more than 100 ships, including dozens of oil tankers, typically passed through the waterway each day.

The increase in maritime activity comes after the U.S. Navy ended its blockade of Iranian waters as part of a broader understanding with Tehran. Iranian authorities have also announced that commercial vessels will be allowed to transit the Strait of Hormuz without paying tolls for a period of 60 days, a move intended to encourage shipping companies to resume operations.

The Strait of Hormuz is a vital route for global energy supplies, carrying a significant portion of the world’s seaborne crude oil exports. Any disruption in the narrow waterway can have immediate implications for international energy markets and shipping costs.

Industry observers will continue monitoring vessel traffic in the coming weeks to determine whether commercial shipping returns to normal levels as confidence in the security of the passage improves.
