Recent tentative agreement between U.S. and Iranian negotiators would extend the existing ceasefire by 60 days, reopen the Strait of Hormuz, ease certain sanctions, and launch new talks on Iran’s nuclear program. The framework emerged in late May after months of indirect diplomacy following the April 2026 ceasefire and its subsequent indefinite extension. Final approval remains pending from President Trump and Iranian leadership, with both sides describing terms as largely negotiated but not yet finalized. An announcement could resolve quickly if endorsements materialize, though unresolved issues around enforcement, uranium enrichment limits, and proxy activities could still alter the timeline. Trader sentiment reflects the proximity of a potential deal amid ongoing diplomatic momentum.
