The International Atomic Energy Agency is stepping into a pivotal role in the latest chapter of US-Iran nuclear diplomacy. Director General Rafael Grossi confirmed that the IAEA will now work with both Washington and Tehran to develop specific technical measures based on a memorandum of understanding between the two countries.
The MOU, scheduled for formal signing on June 19, 2026, in Switzerland, represents a preliminary framework rather than a final deal. It would centralize the IAEA’s verification role over Iran’s enriched uranium stockpiles and establish a structured inspection regime.
A fragile path from airstrikes to agreements
US military strikes targeted Iranian nuclear sites in 2025, creating significant tension. A fragile ceasefire followed, then indirect negotiations that eventually produced this memorandum.
Iran reportedly holds a stockpile of approximately 400 to 1,000 kilograms of 60% enriched uranium. Uranium enriched to 60% is already well beyond what’s needed for civilian energy purposes and sits close to weapons-grade material, which starts at roughly 90%.
