Iran has officially closed the Strait of Hormuz once again, reversing a recent decision to allow commercial traffic. Iranian authorities announced that the strategic waterway will remain inaccessible to shipping until the Trump administration ends its current naval blockade. This development marks a return to heightened tensions following a period of relative calm. The closure follows a brief 10-day window where Iran had allowed vessels to pass through the strait, a period coinciding with a truce between Israel and the Iranian-aligned group Hezbollah. By reinstating the closure, Iran is signaling a direct challenge to the U.S. military presence in the region and the economic pressure campaign led by President Trump. Global markets remain watchful for the impact on energy distribution, as the strait is a primary transit point for world oil supplies.
