US-Iran deal: Key questions remain over status of Strait of Hormuz

Getting enough ships through the strait, refilling inventories, getting refineries back up and running or back to using Middle Eastern crude will take time, and a process over a year possibly, certainly several months. In the case of LNG, a few weeks to get the LNG trains up and running but two trains are also damaged, and they'll take several years or at least one year to repair. So there's a lot that needs to happen before things go back to normal and a lot that could go wrong."
