Ongoing U.S.-Iran negotiations remain stalled under the fragile April 2026 Pakistan-mediated ceasefire, with recent proposal exchanges underscoring deep divides over nuclear enrichment limits, Strait of Hormuz navigation, sanctions relief, and ballistic missile curbs. President Trump rejected Iran’s latest counterproposal in mid-May as unacceptable, describing the truce as on massive life support amid intermittent naval incidents and continued blockades. Direct high-level talks since the April Islamabad meetings have yielded no comprehensive framework, though indirect channels persist. These developments, set against broader regional tensions involving Israel, sustain trader caution that core disagreements and verification challenges will delay any permanent accord resolving military hostilities.
