Recent U.S. and Israeli strikes on Iranian enrichment sites at Natanz, Fordow, and Isfahan have damaged key facilities and buried substantial stockpiles of 60 percent enriched uranium, while IAEA inspectors have lacked access since mid-2025. This verification gap, combined with stalled implementation of a June 2026 U.S.-Iran memorandum on supervised down-blending, sustained sanctions, and the September 2026 IAEA referral of Iran to the UN Security Council for safeguards noncompliance, has reinforced trader consensus that a confirmed nuclear weapon by December 31, 2026, faces steep technical and diplomatic barriers. Construction activity at sites such as Pickaxe Mountain and unresolved regional tensions could still enable accelerated recovery if monitoring remains absent, though such moves would likely prompt renewed international pressure or further action.
