Ongoing indirect US-Iran negotiations via Pakistani mediators have produced a fragile April ceasefire in the 2026 war but stalled on a permanent peace treaty, with traders assigning low probabilities to near-term resolution due to irreconcilable demands over Iran's nuclear program, ballistic missiles, US sanctions relief, and frozen assets. The US one-page memorandum proposal, circulated last week, seeks a Strait of Hormuz reopening and 30-day framework for comprehensive talks including a 20-year uranium enrichment pause, but Iran countered May 8 demanding shorter limits, security guarantees, and full sanctions lift—prompting President Trump to deem it "totally unacceptable" on May 12 and Iran's chief negotiator to issue an ultimatum May 11. Upcoming Pakistani-hosted talks and Trump's China summit could apply pressure, though historical mistrust and mutual threats sustain uncertainty.
