US-Iran ceasefire talks, Strait of Hormuz blockade, and regional conflict updates
Consensus Summary
The US and Iran are engaged in indirect talks to extend a two-week ceasefire expiring on 22 April 2026, with Pakistan mediating negotiations likely to resume in Islamabad. Both sides appear open to prolonging the truce, though Iran demands an end to Israeli attacks on Lebanon as a precondition. Meanwhile, the US naval blockade of Iranian ports, enforced since 15 April, has turned back 10 vessels, including the Chinese-owned *Rich Starry*, and disrupted over 90% of Strait of Hormuz traffic. Iran has retaliated by threatening to block regional trade if the blockade continues. Oil prices remain volatile near $95, as global supply chains adjust to the conflict. US President Donald Trump has signaled optimism about a swift resolution, either through withdrawal or a deal, while Israel continues military operations in Lebanon against Hezbollah, despite regional ceasefire efforts.
