Iran has announced that it is suspending all commitments under the memorandum of understanding (MoU) with the United States. The announcement follows the U.S. resuming sanctions on Iranian oil sales and military actions that Tehran claims violate the MoU, which was signed in June 2026. This memorandum had established a temporary ceasefire to ease tensions between the two nations and their allies. Markets appear to interpret Iran’s suspension as a significant setback to the prospects of reaching a final nuclear agreement by the mid-August deadline, with implications for ongoing negotiations.

Key Takeaways

• Iran’s suspension of MoU commitments appears consistent with a decrease in the likelihood of a US-Iran nuclear deal.
• The market pricing for a final nuclear agreement by August 13, 2026, suggests a persistent low probability, with a current YES price of around 2%.
• The recent developments suggest increased geopolitical tensions, impacting the market’s expectations of a diplomatic resolution.

What to Watch

Observers will be closely monitoring any responses from the U.S. and Iran that might escalate or de-escalate the situation further. Key indicators include statements from Iranian Supreme Leader Ayatollah Ali Khamenei or U.S. President Donald Trump that could either harden or soften stances. Additionally, any renewed diplomatic efforts or mediator involvement, particularly by Oman, could shift the current market outlook significantly. The implications of these diplomatic maneuvers will be crucial as the August 13 deadline approaches for a potential nuclear agreement.
