Navigating the Strait of Hormuz Amid Rising Tensions

The Strait of Hormuz, a critical chokepoint for global oil supply, has seen a significant slowdown in commercial shipping traffic due to escalating tensions from the ongoing U.S.-Israeli military actions against Iran. Despite these risks, some Iranian-linked vessels continue to navigate the strait, with a notable Iranian supertanker recently spotted en route to China. The U.S. military has intensified its presence, urging allies to deploy warships to ensure safe passage through this vital waterway. However, the situation remains precarious, as electronic interference and the disabling of Automatic Identification Systems (AIS) by vessels complicate tracking efforts.

In the face of these dangers, some shipowners, particularly from Greece, have chosen to send crude oil and dry bulk tankers through the strait, motivated by the potential for substantial profits amid soaring crude oil prices. U.S. President Donald Trump has publicly encouraged these risky voyages, asserting that there is "nothing to be afraid of." However, the U.S. military has refrained from providing escorts due to the high risks involved. Reports indicate that at least 10 Greek-operated ships and two Chinese vessels have successfully traversed the strait since the conflict escalated on February 28, despite the threat of attacks from Iranian military forces.

The Iranian oil trade continues to thrive, particularly with China being the primary importer. In 2025, Iranian oil accounted for over 1 million barrels per day of Malaysian crude loadings to China, reflecting a significant increase from previous years. Much of this trade is facilitated by a "shadow fleet" of tankers that operate under false flags to evade sanctions. These vessels often conduct ship-to-ship transfers in international waters, particularly off the coasts of Malaysia and Singapore, where oversight is minimal. Maritime intelligence indicates a rise in such transfers, with 679 documented last year, up from 280 in 2023.

The decision to navigate the Strait of Hormuz during wartime has drawn criticism from various quarters. Stephen Cotton, General Secretary of the International Transport Workers' Federation, has condemned the practice, stating that sending seafarers through the strait equates to placing them in a "live war zone." Concerns have also been raised about the safety of vessels that disable their AIS to avoid detection, with critics labeling this tactic as "gambling with seafarers' lives."

While President Trump has encouraged shipowners to proceed through the strait, the U.S. Navy has communicated to the shipping industry that the risks are too high for military escorts. The White House has not issued a formal response to the ongoing situation. Meanwhile, Malaysia has faced international pressure to address illicit oil transfers occurring off its coast, with recent seizures of tankers suspected of transporting Iranian crude.

As tensions continue to rise and oil prices remain elevated, the dynamics of shipping through the Strait of Hormuz are likely to evolve. Observers note that while the current conflict may deter some vessels, the financial allure of high oil prices could compel others to take the risk. The situation remains fluid, with the potential for significant implications for global oil supply and maritime security.
