The 60-day clock that President Donald Trump set on a final nuclear agreement with Iran ran out on August 17 with nothing signed, and Washington has spent the twelve days since replacing negotiation with pressure. On August 24, Treasury Secretary Scott Bessent announced the widest sanctions wave of the confrontation so far, designating nearly 60 individuals and entities and describing the campaign as the economic asphyxiation of Iran. No date has been set for the technical nuclear talks the two governments promised each other in June, and neither side is publicly asking for one. The file that started the war — how much enriched uranium Iran keeps, and who is allowed to look at it — is now the least discussed part of the confrontation.
The deadline came from the Islamabad Memorandum, the 14-point understanding Trump and Iranian President Masoud Pezeshkian signed on June 17 after months of fighting, brokered by Pakistan alongside Qatar, Saudi Arabia, Turkey and Egypt. It committed both governments to an immediate halt in hostilities, removal of the American naval blockade within thirty days, toll-free passage through the Strait of Hormuz, and a 60-day period to convert a ceasefire into a final agreement covering Iran's nuclear program. It never held. Trump declared the memorandum over on July 8 after attacks on commercial shipping in the strait, and Iran formally suspended its own commitments on July 18, accusing Washington of breaching the text first.
The sanctions announced last week are what replaced it. The Treasury designations reach across oil, shipping, gold, aviation and digital assets, and include a procurement network of more than twenty entities spread across the Middle East and East Asia that American officials accuse of supplying sensitive technology for nuclear research and ballistic missile development. Bessent said every country will be given a defined timeline to wind down its Iranian business before secondary sanctions follow. Tehran's public answer has been defiance rather than a counteroffer: Economy Minister Ali Madanizadeh said American sanctions are not new and that Washington cannot achieve its goals through them, while Pezeshkian acknowledged the shortages at home and told the United States that relying on force and bullying will only complicate the process.
Traders have priced the diplomacy accordingly. On Polymarket, the contract asking whether a qualifying final deal will be signed or formally adopted by August 31 trades at a fraction of a percent, and the version running to the end of December sits near ten percent. Those are not the odds of a hard bargain being struck late; they are the odds that a negotiation restarts at all. The market's own resolution language is a reminder of how far apart the two things are, since it requires a written instrument with a measurable limit on Iran's program rather than another pledge to keep talking.
