Iran's Uranium Stockpile at Isfahan
Analysis based on 20 articles · First reported Apr 29, 2026 · Last updated Apr 30, 2026
The ongoing tensions and military actions surrounding Iran's nuclear program create significant uncertainty in global energy markets, particularly concerning oil and natural gas shipments through the Strait of Hormuz. The potential for Iran to develop nuclear weapons could lead to further sanctions and military interventions, impacting international trade and investment, and increasing volatility in defense and commodity sectors.
The International — International Atomic Energy Agency (IAEA) reports that the majority of Iran's highly enriched uranium, enough for up to 10 nuclear bombs, is likely still stored at its Isfahan nuclear complex, despite past airstrikes by the United States and Israel. Rafael Grossi, the IAEA Director-General, stated that inspections at Isfahan ceased after a 12-day war in June 2025, and the agency relies on satellite images from Airbus to estimate the material's presence. The United States, under Donald Trump, bombed three Iranian nuclear sites and withdrew from the 2015 nuclear deal, aiming to prevent Iran from developing nuclear weapons. Diplomatic efforts are ongoing, with the IAEA discussing with Russia the possibility of removing Iran's enriched uranium. However, recent proposals from Iran to postpone nuclear talks in exchange for ending its chokehold on the Strait of Hormuz were rejected by Donald Trump. Marco Rubio emphasizes that preventing Iran from attaining nuclear weapons remains a core issue, while Rafael Grossi stresses the need for political will from Iran for a comprehensive agreement and full IAEA inspections of all nuclear facilities, including Natanz and Fordo. Iran's proxies, Hezbollah, Hamas, and Houthis, are also part of the broader discussions.
