UN snapback sanctions on Iran take effect

2025-09-28 00:00 UTC · policy

Pre-2015 UN sanctions on Iran, including the arms embargo, ballistic-missile restrictions and asset freezes, were automatically reinstated at midnight GMT on Sunday September 28 after the E3 triggered the JCPOA snapback mechanism on August 28. The reimposition occurred over a weekend, before Monday's market open, and was widely anticipated.
