Diplomatic efforts to de-escalate the conflict between Iran and the United States have hit a dead end, as Tehran refuses to engage in talks until Washington lifts its naval blockade of Iranian ports. The standoff, which has effectively choked off nearly all traffic through the Strait of Hormuz, shows no sign of resolution.
On Wednesday, Iran's Islamic Revolutionary Guard Corps (IRGC) fired on three vessels in the strategic waterway and seized two of them, marking a sharp escalation. The attacks came less than a day after US President Donald Trump extended a fragile ceasefire while maintaining the blockade. The strait, through which about 20% of the world's traded oil passes in peacetime, remains largely closed to commercial shipping.
Iranian state media reported that the MSC Francesca and the Epaminondas were being escorted to Iran. Technomar, the management company behind the Liberian-flagged Epaminondas, said the vessel was “approached and fired upon by a manned gunboat” off the coast of Oman, damaging the ship's bridge. A second cargo ship was also fired upon but reported no damage, though it was stopped in the water. No crew injuries were reported. Panama, whose flag the Epaminondas flies, condemned the “illegal seizure” as a “serious attack” on maritime security. A third vessel, the Euphoria, was attacked and later became “stranded” on the Iranian coast, according to Iranian media.
White House Press Secretary Karoline Leavitt defended the US position, stating that the seizures did not violate the truce because the vessels “were not US or Israeli.” The US had earlier seized two Iranian vessels as ceasefire talks were due to take place in Pakistan, prompting Tehran to withdraw from the second round of negotiations.
Economic Fallout for Europe
The conflict has sent energy prices soaring far beyond the region. Brent crude has surged past $100 per barrel, a roughly 40% increase compared to pre-war levels. European Union Energy Commissioner Dan Jørgensen warned of lasting consequences for consumers and businesses, likening the disruption to major energy crises of the past half-century. He estimated that the crisis is costing Europe approximately €500 million each day.
The ripple effects are being felt across global supply chains, raising the cost of food and a wide array of other products. While stock markets have so far shrugged off the price increases, the sustained disruption could have deeper economic implications. For context, the EU has been grappling with energy security since the war in Ukraine, and this new crisis compounds existing vulnerabilities. The EU leaders meeting in Cyprus have been discussing the Hormuz crisis alongside Ukraine and mutual defence commitments.
Iran's ability to restrict traffic through the strait has proven a major strategic advantage. While the ceasefire has halted American and Israeli airstrikes on Iran and stopped Tehran's missile attacks on Israel and the wider region, the maritime standoff continues and could escalate further. Without a diplomatic agreement, the attacks will likely deter even more ships from attempting the passage, tightening the chokehold on global energy supplies.
Mohammad Bagher Qalibaf, Iran's parliament speaker and chief negotiator who met with US Vice President JD Vance in Pakistan earlier this month, stated that a complete ceasefire “only makes sense” if it is not violated by Washington's blockade of Iranian ports. “Reopening the Strait of Hormuz is impossible with such flagrant breach of the ceasefire,” he wrote on X. Iranian officials have demanded the full dismantling of the US Navy's blockade for talks to resume, but Trump insisted on Wednesday that the blockade will remain until Iran lifts its restrictions on maritime passage.
Trump also claimed a diplomatic victory late Wednesday, alleging that Iran had “respected” his request and called off the executions of eight Iranian women arrested during anti-government protests in January. “I very much appreciate that Iran, and its leaders, respected my request, as President of the United States, and terminated the planned execution,” he wrote on Truth Social. Tehran dismissed the claim as a “fabrication” and a desperate attempt to “save face,” adding that the women were never going to be executed. “Trump's empty-handedness in the battlefield has pushed him towards fabricating achievements from false news,” the Iranian judiciary's news agency, Mizan, said.
The crisis has also drawn in other regional actors. Qatar has urged diplomacy as the talks in Islamabad face uncertainty. Meanwhile, the broader conflict has already seen more than 30 attacks on ships in the Middle East since the US and Israel launched their surprise attack on Iran on 28 February. Before that, the strait was fully open for all maritime traffic.
For European readers, the stakes are clear: the disruption of a key energy artery directly affects fuel prices, inflation, and economic stability across the continent. The EU's energy commissioner has already warned of lasting impact, and the daily cost of €500 million underscores the urgency for a diplomatic resolution. As the standoff continues, the risk of further escalation remains high, with no clear path to de-escalation in sight.
