Perhaps I’m not understanding how this works. But these are unimaginable sums. Let’s say Iran wants a 5% fee, the low end of the demand Trump is accepting. Approx. 20% of global oil production goes through the strait. So 5%, 20% … this means Iran takes a 1% cut off the top of the export …
Reuters: Iran wants fees of 5%-7% of the price of cargo from ships using the strait; Oman wants 3%. "Making fees voluntary, at least nominally, could be a way out of the impasse, although an implied threat of Iranian attacks could mean shippers would be unlikely to risk transit without paying."
