The shadow of the 1970s oil embargo has returned to haunt the global economy, but with a modern, more violent twist.

In the latest escalation, a Liberia-flagged containership has been left with heavy damage to the bridge after being subjected to gunfire from an Iranian Revolutionary Guard Corps (IRGC) boat. The attack occurred 15 nautical miles northeast of Oman. Despite the vessel reportedly having permission to transit the Strait of Hormuz and making no prior VHF contact with the attackers, the IRGC opened fire at close range, likely in revenge for US forces firing on and taking control of an Iranian boxship earlier in the week.

The geopolitical gridlock shows no signs of easing. President Donald Trump confirmed yesterday he will extend the current ceasefire with Iran while maintaining the US maritime blockade, citing a request from Pakistan to allow for unified negotiations. However, the ceasefire on land is not reflected at sea.

US forces have significantly expanded their crackdown, moving beyond the Gulf to hunt Iranian tonnage far and wide-a strategy reminiscent of the naval pressure applied to Venezuela earlier this year. On Tuesday, US forces boarded the sanctioned tanker Tifani in the southern Bay of Bengal. The vessel, described by the Pentagon as “stateless” and accused of falsely flying the flag of Botswana, was interdicted while suspected of smuggling oil loaded at Iran’s Kharg Island.

The crisis has effectively paralysed the region. Since the Iran war effectively closed the Strait of Hormuz on February 28, daily traffic has collapsed by 97%. More than 800 ships remain stranded west of the strait, with thousands of seafarers caught in a high-stakes limbo.

The humanitarian cost is drawing comparisons to the darkest chapters of maritime history. Earlier this month, the United Nations labelled the Hormuz crisis the worst crisis for seafarers since World War Two.

According to maritime AI firm Windward, the first quarter of 2026 has been defined by geopolitical shock. In an assessment of the current landscape, Windward noted that “the machinery of global shipping was tested as it has not been in a generation.” The firm highlighted a global record in vessel interdictions, with boarding and detentions up 160% over the previous quarter.

“Fifty years after the global economy reeled from a Middle East oil embargo, this quarter has opened a new inflection point,” Windward reported in its Q1 roundup. 

As the shadow fleet expands to over 2,100 vessels – nearly 66% of which are now sanctioned – the firm warned that 2026 is shaping up to be the most “turbulent” year for shipping in half a century.
