Not saying you are wrong but has this been reported anywhere? As far as I understand, the markets flipped yesterday purely on the headline of Iran saying they were open to a deal. The deal they are asking for is reparations, control of the strait, assurance of no future attacks, and for the US to mostly pull out of opposing gulf states. This was pretty much the same thing they asked for in previous weeks.
The odds of really any of those things happening are just as probable of them agreeing to the US 15 point plan.
