Iran officially suspended its indirect negotiations with the United States on June 1, citing ongoing Israeli military operations in Lebanon and Gaza as the breaking point. Tehran views these operations as violations of ceasefire agreements, and it’s backing up its frustration with one of the most consequential economic threats in its arsenal: closing the Strait of Hormuz.

The Strait handles roughly 20-25% of the world’s oil and liquefied natural gas trade.

A conflict that keeps escalating

The broader confrontation between Iran and the US has been building since late February 2026. It’s been a cycle of ceasefire attempts, naval blockades impacting Iranian ports, and negotiations conducted through intermediaries including Pakistan.

Ceasefire talks have been ongoing since April 8 but have repeatedly collapsed. The sticking points: Israeli actions in Lebanon and unresolved nuclear discussions.
