Iran is set to allow United Nations nuclear inspectors back into the country, US Vice President JD Vance said, marking a significant shift in the ongoing diplomatic standoff.

The development suggests a thaw in tensions that have long weighed on regional stability and global energy supply chains.

Vance characterized the emerging framework for a potential peace deal as a brief, one-and-a-half-page document that is "very general" in its scope.

While the specifics remain vague, the agreement to restore inspector access is a concrete step toward verifying Iran's nuclear activities and reducing the immediate threat of military confrontation.

For markets, the news provides a counterweight to the persistent shipping risks and geopolitical friction that have kept a premium on oil and freight rates.

Investors have been closely monitoring the Strait of Hormuz for disruptions, and any signal of diplomatic progress tends to ease the risk premium embedded in energy prices.
