Oil prices move up and down as traders weigh shifting expectations for a US-Iran diplomatic breakthrough and the status of shipping through the Strait of Hormuz. Multiple reports say prices rise when prospects improve—such as optimism around a potential or extended ceasefire and hopes that Hormuz could reopen to tanker traffic. Other reports describe price drops after US President Donald Trump signals negotiations are in the “final stages” but also warns of renewed strikes if Iran does not agree to a deal, prompting concern that tensions could flare again.

Several outlets link the market’s volatility to the practical reality that the strait remains mostly closed, limiting oil and gas flows. Iran’s actions are described as restricting traffic through Hormuz, while the United States is described as blockading Iran’s coastline, leaving supply disruptions as a key driver of investor sentiment.

Analysts referenced in the coverage also point to tightening inventories as countries draw down commercial stocks and, in the US case, take large withdrawals from the Strategic Petroleum Reserve. Across reports, traders remain focused on whether an interim or renewed agreement can restore shipping, and how quickly any changes might occur.
