Iran Ultimatum: Strait of Hormuz Tensions Roil Markets & Trigger Global Alert | CNBC

A deadline issued by U.S. President Donald Trump to Iran for the full reopening of the Strait of Hormuz is set to expire at 19:55 Eastern Time tonight, escalating tensions in a region already bracing for a wider conflict. The ultimatum, delivered Saturday, threatens to “obliterate” Iran’s power plants should Tehran fail to comply.

In response, Iranian officials have vowed to target U.S. Infrastructure in the Gulf, including energy and desalination facilities, should the U.S. Carry out its threat. A statement from the Iranian Parliament warned that financial institutions supporting the U.S. Military budget were also considered legitimate targets, and cautioned that purchasers of U.S. Treasury bonds were effectively financing potential attacks on their own assets.

The escalating rhetoric has rattled global markets. Stock markets in Asia, particularly in Japan and South Korea, experienced declines Monday, while oil prices initially surged before reversing course. The volatility reflects uncertainty surrounding the potential for military escalation and disruption to vital energy supplies.

British Prime Minister Keir Starmer is scheduled to chair an emergency meeting later today with Chancellor of the Exchequer Rachel Reeves and Bank of England Governor Andrew Bailey to address the economic ramifications of the escalating conflict. This follows a direct conversation between Starmer and Trump, focusing on the critical need to restore free passage through the Strait of Hormuz, a key artery for global oil transport.

The situation is further complicated by a separate incident at New York’s LaGuardia airport, where an Air Canada plane collided with an airport fire rescue truck upon landing. Details regarding passenger welfare have not yet been released.

The International Energy Agency (IEA) has warned that the current crisis could trigger an energy shock exceeding the scale of the 1970s oil crises, should the Strait of Hormuz remain closed or significantly restricted. This assessment underscores the global economic stakes involved in the standoff.

Recent reports indicate a shifting strategy from President Trump regarding the Strait of Hormuz, prompting questions about the level of U.S. War preparation. The evolving approach has introduced further uncertainty into an already volatile situation.
