Negotiations for a permanent US-Iran peace deal remain stalled after a fragile two-week ceasefire agreed on April 8, 2026, and mediated by Pakistan amid the ongoing war over the Strait of Hormuz, nuclear limits, and sanctions. President Trump declared the truce on "life support" yesterday, criticizing Iran's response as unacceptable, while Tehran accused the US of ceasefire violations and demands full sanctions relief, frozen asset releases, and Hormuz sovereignty recognition before addressing nuclear rollback. Key disputes center on verification of Iran's ballistic missile program and guarantees against future US or Israeli strikes, with no next talks scheduled despite US proposals for a comprehensive framework. Traders weigh deep mistrust and escalation risks against diplomatic pressures, including proxy de-escalation in Lebanon.
