Iran maintains that uranium enrichment remains a core sovereign right and non-negotiable red line in talks with the United States, as reflected in its consistent positions during 2025–2026 negotiations and the June 2026 memorandum of understanding. That MOU froze further expansion and enrichment activity temporarily while deferring final decisions on Iran's program, stockpile dilution, and facilities to a subsequent 60-day period, without any commitment to permanent cessation. IAEA reporting and official statements confirm ongoing enrichment capacity despite prior strikes on sites, and Iranian officials have rejected U.S. demands for long-term moratoriums or dismantlement. With the September 30 deadline weeks away, the absence of any recent diplomatic breakthrough sustains trader consensus against an agreement. A sudden shift in the final negotiation window or major concession on both sides could still alter the outcome before resolution.
