Living with the Snapback: What the New U.N. Measures Mean for Iran

A U.N. process to reimpose sanctions on Iran was started when France, Germany and the United Kingdom triggered a 'snapback' notification on August 28, 2025. A Security Council vote on September 19 failed to keep sanctions relief in place, and U.N. measures will be reimposed on September 28, 2025. The measures include arms embargoes, asset freezes, travel bans and limits on uranium enrichment.

The Iranian economy has been under severe strain. Inflation has risen sharply and the IMF projects it will reach about 43% in 2025. People have experienced repeated power cuts and long water shortages while some regions faced heat-related strains. Many families have already reduced spending on food and essentials, and therefore basic needs are under pressure. However, some trade ties continue and Iran still moves some oil through other channels, which has mitigated a total collapse.

The IAEA has reported that inspections have been limited since June, and this lack of oversight has heightened international concern. Furthermore, diplomats and analysts have said the snapback will increase isolation and could squeeze trade, finance and energy flows for Iran.
