US spot petrochemical prices softened last week as the Iran risk premium unwound, reducing export demand; Gulf Coast operational issues limited further downside. Ethylene fell 4.1% and polymer‑grade propylene dropped 9.8%; both remain above pre‑war levels after Middle East shipment disruptions via the Strait of Hormuz tightened global supply and supported earlier US export flows. The price of para‑phenylene di‑n‑butyl ether, more than 70% used in synthetic rubber tires, held at 63.5 cents/lb, ma

Ben May and Bridget Payne at Oxford Economics said the U.S.-Iran agreement reduces the risk that sustained declines in oil inventories would trigger a global energy-price shock and recession, though risks remain. They said the deal does not automatically mean oil flows through the Strait of Hormuz will recover faster than previously assumed — they had expected transit to resume by end-July — and their near‑term oil‑price forecasts still look high. They added that reopening the strait is likely to ease inflation but provide only limited support to growth, reinforcing their view that the Fed and Bank of England will not hike further and that other central banks that have finished tightening are unlikely to resume hikes.
