There are multiple issues that will force a lag of at least a couple of months. First, the issue of the mines that have been reported. Second, the tanker owners will want to be quite sure hostilities aren't going to erupt again. Third, while tankers that are trapped will leave, there will be a major lag while tankers that have been moved to other parts of the world get redirected back to the Strait to fill up. It will indeed be months before there is enough oil flowing to start retaining reserves again. It isn't like the state of shipping was frozen the day the war started and will unfreeze as soon as the ink is dry on the new cease-fire deal.
