UN Sanctions on Iran Likely to Be Reimposed Amid Nuclear Deal Deadlock
Published Date: 20th Sep, 2025
New York / Tehran, September 20, 2025 — United Nations sanctions on Iran are set to return before the end of September, as European powers move to trigger the so-called “snapback” mechanism after accusing Tehran of failing to uphold commitments under the 2015 nuclear agreement.
What’s happening
In late August, the United Kingdom, France, and Germany — often referred to as the “E3” — activated the snapback provision under UN Security Council Resolution 2231. The move came after repeated warnings that Iran was not meeting key nuclear obligations, including cooperation with international inspectors and limits on uranium enrichment.
Unless Iran demonstrates compliance, the suspended UN sanctions will automatically be reinstated once the 30-day deadline expires. French President Emmanuel Macron has already stated that, in his view, Iran’s latest responses are insufficient to avert this outcome.
What the sanctions would cover
The reimposed measures are expected to include:
-
A renewed arms embargo
-
Restrictions on ballistic missile activity
-
Limits on uranium enrichment and reprocessing capabilities
-
Asset freezes and travel bans on individuals and entities linked to Iran’s nuclear and missile programs
Iran’s reaction
Tehran has denounced the snapback process as “illegal,” insisting its nuclear program is strictly civilian in nature. President Masoud Pezeshkian has declared that Iran can withstand renewed sanctions, stressing the country’s resilience in the face of external pressure. Officials maintain that allegations of non-compliance are politically motivated and exaggerated.
Stakes & implications
If sanctions are reimposed, Iran faces renewed isolation in global trade and finance, complicating its already fragile economy. Companies and governments engaging with Tehran would risk penalties, likely curbing foreign investment and tightening restrictions on technology transfers.
Diplomatic efforts are still ongoing, but the window is narrowing. European officials suggest Iran still has a chance to avoid sanctions if it takes verifiable steps toward compliance.
What comes next
The UN Security Council is expected to review the matter in the coming days, but few expect a resolution to block the snapback. Unless a last-minute compromise is reached, sanctions will automatically reapply at the end of the 30-day period, placing fresh strain on Iran’s economy and further escalating tensions between Tehran and the West.
The likely reimposition of UN sanctions signals a critical moment for Iran’s international standing. With little time left for compromise, Tehran faces renewed economic and political pressure, while the international community confronts the challenge of enforcing non-proliferation rules in an increasingly volatile Middle East.
