What Happened

On April 10, 2026, direct U.S.-Iran negotiations convened in Islamabad, Pakistan — the first such talks following the April 7 provisional ceasefire. The summit was hosted by Pakistan with Chinese backing. Iran presented a 10-point demand list that included full lifting of U.S. sanctions, preservation of Iranian control over the Strait of Hormuz, and agreement to limit uranium enrichment to 3.67% in exchange for access to frozen assets abroad. President Trump signaled willingness to ease sanctions in exchange for Iranian concessions, posting on social media: "We are, and will be, talking Tariff and Sanctions relief with Iran." Experts assessed any sanctions relief would be gradual and tied to compliance on nuclear and other commitments. The Soufan Center noted Tehran believes Trump will not risk collapse of the truce given the economic and political costs. A durable ceasefire was not confirmed at the conclusion of the summit; negotiations are ongoing.

Significance for the Crisis

The Islamabad summit is the single most consequential diplomatic event since the February 28 conflict onset. Its outcome determines whether the April 7 provisional ceasefire hardens into a durable arrangement or collapses back into active hostilities. A durable agreement would begin the 45–60 day physical market normalization timeline estimated by Vitol/Trafigura, potentially supporting the EIA's $76/b by 2027 recovery path. Failure would likely trigger Morgan Stanley's $150–$180/b scenario, with demand destruction becoming the market-clearing mechanism instead of supply restoration. The 3.67% enrichment ceiling and Hormuz control provisions in Iran's demands indicate Iran is seeking both economic relief (sanctions removal, frozen assets) and strategic legitimacy (nuclear rights, regional authority) — a package the U.S. is unlikely to accept in full. The intermediate outcome — gradual sanctions relief tied to compliance — is the most probable path, but it leaves the ceasefire provisional and the market under uncertainty through Q2 2026.
