Confusion and Uncertainty Reign Over Strait of Hormuz as US and Iran Issue Divergent Navigation Directives

The Strait of Hormuz remains a flashpoint of confusion and tension, as the United States and Iran continue to issue conflicting navigational instructions to shipowners, leaving vessel operators in a perilous bind. According to the Financial Times (FT) and other reports, Iran has allowed a limited number of ships to pass through the vital waterway daily, with authorizations varying based on circumstances, while Washington advises ships to use a route closer to Oman under US air cover. The contradictory guidance has created deep uncertainty among shipping executives, who must balance the risk of Iranian detention or sanctions-related concerns.

Iran’s Armed Forces opened the strait but imposed a daily cap on vessel transits, with the number of authorizations changing each day depending on circumstances, as reported by Fars news agency. However, the reopening proved fragile; according to an eyewitness account from Xinhua, the strait was reopened and then closed again the following day after Iran’s military cited Israeli violations of a ceasefire in Lebanon. US Central Command, meanwhile, maintained that traffic continued to flow, underscoring the lack of clarity on the ground.

The standoff traces back to Feb. 28, when Iran effectively blocked the strait after joint US-Israeli strikes on the country. The US then imposed a naval blockade on Iran from April 13 to pressure Tehran into reopening the waterway. Before the crisis, some 130 vessels passed through daily; during the conflict, traffic fell to single digits. Maritime tracking firm Kpler recorded at least 36 commodity carriers on Monday, signaling a tentative recovery, though levels remain far below prewar norms.

The uncertainty has rippled beyond shipping. In the Omani town of Khasab, local tourism, which relies on visitors cruising the region’s desert fjords, has suffered a heavy blow. “Everyone is hoping for stability to return, and for visitors to come back," one dhow captain told Xinhua. Meanwhile, diplomatic efforts continue: US and Iranian representatives held talks in Switzerland mediated by Pakistan and Qatar, with mediators reporting “encouraging progress” including the establishment of a communication line for safe commercial passage and a “de-confliction cell” to address military operations in Lebanon. US President Donald Trump stated Monday that the strait was “totally open,” a claim at odds with the complex and contradictory reality on the ground.
