A deepening conflict in the Strait of Hormuz, which handles a fifth of the world's oil trade, has sent crude prices surging over 6% and threatens a prolonged global supply shock.

(P1) Oil prices surged Wednesday as the escalating conflict between the US and Iran threatened to cause a prolonged global supply shock, with West Texas Intermediate crude climbing more than 6% to trade above $105 a barrel for the first time in weeks. The rally intensified after President Donald Trump warned Tehran to accept US demands on its nuclear program and reopen the Strait of Hormuz, a critical chokepoint for global energy shipments.
(P2) "The disruption is both rapid and unprecedented," said Dimitris Ampatzidis, a maritime risk and compliance manager at the analytics firm Kpler. He noted that overall traffic through Hormuz in the last two months has run at about 5% of the pre-war average, with many shipping operators avoiding the area entirely.
(P3) The market reaction was swift and broad. WTI crude for June delivery traded near $105 at press time, while the global benchmark, Brent crude, rose roughly 5% to trade above $110 a barrel. Before the conflict began, about 15 million barrels of crude oil and other petroleum products passed through the strait daily, according to Kpler data, accounting for about one-fifth of the world's oil trade. In March, total vessel crossings fell to just 154, a fraction of the typical 3,000 per month.
(P4) The standoff now risks a wider energy crisis that could fuel global inflation and severely impact economic growth, particularly in Asia. The conflict has already widened beyond Hormuz, with a senior Iranian lawmaker renewing threats to disrupt the Bab el Mandeb strait in Yemen if the US continues its blockade of Iranian ports. With talks stalled and the US preparing for a longer pressure campaign, the potential for a sustained loss of barrels that cannot be replaced from other regions grows, threatening to scar the world economy for years.
The escalation follows the launch of a joint US-Israeli military operation against Iran nine weeks ago. In response to Iran's subsequent control over the Strait of Hormuz, the US announced a blockade on ships entering or exiting Iranian ports on April 13. US Central Command reports that its forces have directed at least 38 vessels to turn around since the blockade began.
Despite the blockade, a significant portion of traffic is operating outside verifiable corridors, creating a fleet of "dark" vessels. Data shows that about half the ships that have recently transited the strait did so along a new route designated by Iranian authorities along their coastline, with many loading cargoes at Iranian ports in defiance of US sanctions.
The conflict has already cost an estimated $25 billion, according to Pentagon officials, and is reshaping global supply chains. Key US allies in Asia, such as Japan and South Korea, were major importers of Middle Eastern crude and are now facing shortages of refined products. "If the situation is prolonged, we’re going to see loss of barrels that cannot be replaced from anywhere," said Ioannis Papadimitriou, lead freight analyst at Vortexa. "This is where we could see the real loss of cargoes — really hitting the shipping industry."
