A marine traffic map shows the Strait of Hormuz at a standstill more than 48 hours after President Donald Trump announced a two-week ceasefire conditional on Iran reopening the waterway. Automatic identification system (AIS) data on MarineTraffic.com appears to show traffic through the critical chokepoint has barely moved between 11:01 UTC (12:00 PM BST) on 9 April and 11:00 UTC (12:00 PM BST) on 10 April. The strait, through which about 20% of the world’s oil normally passes, has been effectively blocked since the Iran-US war began in late February, causing oil prices to surge and raising energy and agricultural costs worldwide.
