Potential U.S.-Iran Peace Deal Could Send Oil Prices Down $20 a Barrel in a Week

Washington and Tehran are reportedly closing in on a peace deal that could trigger an immediate $20-per-barrel crude price crash, according to sources cited by OilPrice.com on June 1, 2026. The agreement would end a three-month conflict and may ultimately leave the market oversupplied. Macquarie Group strategist Vikas Dwivedi estimates that upon a credible deal, a sell-off of roughly $20 a barrel would occur within one week, followed by a two-week consolidation. As ship traffic through the Strait of Hormuz normalizes and backlogged flows resume over two to four weeks, additional supply would overshoot demand, driving prices toward a “fair value” range of $65 to $70 a barrel. The potential deal follows U.S. strikes that severely damaged Iran’s nuclear and missile infrastructure but left the regime intact and still in control of the critical Hormuz waterway. With U.S. mid-term elections in November 2026 and gasoline prices above $4 a gallon, President Trump faces pressure to lower energy costs. Iran is seeking reparations, possibly framed as an investment fund, but may delay compliance over distrust of U.S. intentions.
