The collapse of high-stakes US-Iran peace talks in Islamabad on April 12, after 21 hours of negotiations led by Vice President JD Vance, has heightened uncertainty over the fragile two-week ceasefire, driving recent rial devaluation as traders anticipate potential re-escalation or prolonged sanctions. The free-market USD/IRR rate on sources like Bonbast and Alanchand stands near 1.608 million rials per dollar as of April 13, up 0.81% daily amid low Strait of Hormuz shipping traffic despite partial reopening and Iranian transit fees. Polymarket traders price a 44% chance of hitting 1.7 million by April 30, reflecting devaluation pressures from war damage, oil market strains, and stalled sanctions relief discussions, with 15% odds for 1.8 million—though diplomatic breakthroughs or US blockades could shift dynamics before resolution on finalized Bonbast data.
