Ongoing US-Iran negotiations following the June 2026 interim agreement and ceasefire have centered on IAEA verification of Iran's nuclear sites, particularly access to Fordow, Natanz, and Isfahan where highly enriched uranium stockpiles are believed stored under rubble from prior strikes. IAEA Director General Rafael Grossi has stated that inspections "will indeed take place" and that technical work on modalities, dates, and procedures is underway, citing explicit provisions in the memorandum for supervision of nuclear material. Iran has denied any current plans or agreements for visits to the damaged enrichment facilities, indicating such steps remain contingent on a final deal and sanctions relief. The agency has conducted limited inspections at unaffected sites like Bushehr but lacks data on centrifuge status or uranium inventories at the three key locations. Trader sentiment reflects uncertainty over timing amid these diplomatic frictions and Iran's emphasis on sovereignty in implementation.
