US-Iran negotiations toward a permanent peace deal stalled after President Trump rejected Tehran's counterproposal on May 11, 2026, calling it unacceptable amid ceasefire violations including exchanges of fire near the Strait of Hormuz. Pakistan-mediated talks in Islamabad earlier produced a fragile two-week truce extended multiple times, with the US pushing a 14-point framework demanding Iranian moratorium on nuclear enrichment, ballistic missile curbs, and Hormuz reopening for sanctions relief and war cessation. Tehran seeks upfront permanent truce guarantees, citing security risks and historical grievances. VP Vance's involvement signals potential de-escalation, but Trump threats of bombing and proxy tensions sustain uncertainty; next diplomatic rounds could tip trader consensus on timelines.
