The ships moving through the Iran channel are likely paying a fee to the Iranian Revolutionary Guard Navy. This is the normalization of the 'Tehran toll booth' — Iran seeking to control every ship traversing the waterway. The question is whether President Trump will accept this end state. Gulf countries want full normalization, not this limited arrangement. 20 ships are moving versus the normal 100 per day.
This represents a near-term ceiling, not a return to normal. If every ship must get Iranian approval, we won't normalize at the 100-ship level.
