IAEA board passes resolution demanding Iran report uranium stocks

The International Atomic Energy Agency’s Board of Governors has passed a resolution demanding Iran provide immediate and detailed information about its enriched uranium stockpile. The move, backed by the US and E3 nations (Britain, France, and Germany), ratchets up international pressure on Tehran at a moment when its nuclear program sits uncomfortably close to weapons-grade capability.

Iran’s uranium stockpile currently stands at approximately 440.9 kg enriched to 60% purity. That’s a short technical hop from the 90% threshold needed for a nuclear weapon, which is precisely why the IAEA’s language in this resolution used words like “essential” and “urgent.”

What the resolution actually demands

The core of the resolution is straightforward: Iran needs to account for its nuclear material “without delay.” The IAEA board described this accounting as “long overdue.”

This isn’t the first time the board has tried this approach. A previous resolution passed in November 2025 made similar demands. Iran has yet to comply with that one.

The current resolution also emphasizes the need for inspector access to verify compliance and assess the status of nuclear sites that were previously damaged in military strikes.

Russia, China, and Niger opposed the resolution.

The geopolitical backdrop

Prior to this resolution, Iran suspended cooperation with IAEA inspectors following military strikes by Israel and the US on key Iranian nuclear facilities in 2025, including facilities at Natanz, Isfahan, and Fordow. Those strikes disrupted not just the physical infrastructure but also the already fragile diplomatic relationship between Tehran and the international nuclear watchdog.

The 440.9 kg figure for uranium enriched to 60% is itself an estimate, which highlights the problem. When inspectors can’t get into facilities, estimates are all you have.

Previous similar resolutions have passed with significant support from the board. The opposition from Russia and China, while consistent with their broader diplomatic posture toward Iran, hasn’t been enough to block these measures.
