Recent U.S. sanctions under Operation Economic Outcast, including designations targeting Iran's petroleum sector, shadow fleet vessels, and financial networks, have intensified pressure on the rial, pushing the open-market rate to around 2.02 million per dollar in late August amid reduced oil export revenues. Traders weigh these measures against Iran's stated two-year contingency plans, ongoing Chinese purchases, and any potential for negotiated relief or enforcement gaps before month-end. With the street rate hovering near 2.0 million and historical volatility tied to oil flows and secondary sanctions, the evenly distributed probabilities across the 1.7–2.2 million+ ranges reflect uncertainty over whether fresh enforcement will drive further depreciation or whether adaptive trade channels will stabilize the currency within the resolution window.
