Trump Issues Ultimatum to Iran Over Strait of Hormuz

European stock markets are expected to open with marginal gains on Tuesday as investors navigate extreme uncertainty surrounding a looming deadline set by U.S. President Donald Trump for Iran. The primary point of contention is the reopening of the Strait of Hormuz, a critical artery for global energy supplies. Trump has issued a stark ultimatum, demanding the strait be opened by 8 p.m. E.T. on Tuesday, threatening to 'decimate' Iranian bridges and power plants within four hours if the demand is not met. This aggressive stance is contrasted by Trump's own comments suggesting that Iranian leadership is negotiating 'in good faith,' leaving investors confused by the mixed messaging from the U.S. administration. Market reactions have been volatile. While European indices like the FTSE 100, Cac 40, and Dax are poised for slight increases following a four-day Easter break, Asia-Pacific markets have experienced significant swings, with major indices flipping to losses due to war-related anxiety. Beyond the geopolitical tension, the economic fallout is already becoming apparent; in Germany, petrol prices have surged, prompting the government to consider new legislation to mitigate the cost of living for citizens. Investors are now looking toward the release of March PMI manufacturing data for the U.K. and Eurozone to gauge the tangible impact of the conflict on the European economy.

Crude oil prices have surged as U.S. President Donald Trump reaffirmed a Tuesday deadline for Iran to fully reopen the Strait of Hormuz. Trump has threatened to destroy Iran's civil infrastructure, specifically power plants and bridges, warning that the nation could be 'taken out in one night' if the deadline is not met. This geopolitical tension has caused a significant supply shock since the conflict began on February 28, driving up the costs of crude, jet fuel, diesel, and gasoline. WTI crude futures rose over 2.9% to $115.63 per barrel, while Brent crude climbed to $111.43. While shipping through the Strait of Hormuz has seen a marginal increase—with eight tankers transiting on Monday compared to a March average of fewer than two—traffic remains a fraction of the 20 million barrels per day seen in 2025. Diplomatic efforts are ongoing, with reports that the U.S. and Iran are discussing a framework to end the five-week conflict. Iran has rejected a U.S. ceasefire proposal, offering its own 10-point plan that demands a permanent end to hostilities, the lifting of sanctions, and reconstruction. Trump described Iran's proposal as a 'significant step' but noted it is 'not good enough.' Market analysts, including Ed Yardeni and Michael Wan, suggest the outcome remains unpredictable, with the 'fog of war' persisting and a full recovery of energy supplies to Asian economies potentially taking three to six months.

Tensions in the Middle East have reached a critical peak as US President Donald Trump issued a final ultimatum to Iran, demanding the reopening of the Strait of Hormuz by Tuesday at 8pm EDT. Trump has threatened to destroy all of Iran's power plants and bridges if the deadline is not met, stating that the country could be 'taken out in one night.' Despite warnings regarding potential war crimes associated with targeting key infrastructure, Trump expressed no concern over these risks. This escalation follows Iran's rejection of a 45-day ceasefire proposal mediated by Pakistan, with Tehran instead demanding a permanent end to the conflict. The regional instability is manifesting in several ways: the King Fahd Causeway linking Saudi Arabia and Bahrain has been closed as a precaution against Iranian attacks, and gold prices remain steady as investors brace for the deadline. Meanwhile, the UN Security Council is preparing to vote on a resolution regarding the Strait of Hormuz, though the text has been watered down by veto-holding members. On the ground, the conflict continues to inflict casualties and damage. Israeli military forces have launched a 'wave' of air strikes targeting Iranian infrastructure in Tehran and other regions, including a strike that destroyed a synagogue in Tehran and another that killed a Philippine national and her family in Haifa. In a rare diplomatic development, Iran released a Japanese national, believed to be an NHK bureau chief, who had been detained since January. Despite these movements, the geopolitical situation remains volatile as the US and Israel increase pressure on the Iranian regime.

The UN Security Council is scheduled to vote on April 7 on a resolution regarding Iran's blockade of the Strait of Hormuz. The current version of the resolution is significantly 'watered down' compared to earlier drafts. Originally, Bahrain and other Gulf oil-exporting nations pushed for a mandate that would explicitly authorize the use of force to unblock the critical waterway, which has been effectively blocked since the start of a war involving the United States and Israel on February 28. However, due to potential vetoes from permanent Security Council members, the language has been softened. The revised text now demands that Iran cease attacks on commercial vessels and stop impeding freedom of navigation, but it stops short of authorizing military force. Instead, it 'strongly encourages' member states to coordinate defensive efforts, such as escorting merchant ships, to ensure maritime security. The resolution also indicates the Council's readiness to consider further measures if navigation remains undermined. This diplomatic effort is occurring under extreme time pressure, as the vote is set to take place just nine hours before a deadline imposed by US President Donald Trump, who has threatened attacks on Iranian power plants and bridges if a deal is not reached.
