US President Trump posted on social media that the US will “guide” commercial shipping through the Strait of Hormuz. Media reports suggest this will not involve naval escorts. Iran’s parliamentary security committee head Aziz called the posts delusional. The oil market reaction gives weight to the Iranian view. US gasoline prices are approaching USD 4.5 per US gallon, which is an incentive for the administration to use calming rhetoric to guide markets. This has less impact as the point of physical shortages moves closer.
