President Donald Trump announced Sunday that a peace deal between the United States and the Islamic Republic of Iran is now complete [1].

The agreement ends a naval blockade of the Strait of Hormuz, a critical chokepoint for global energy markets, and marks the conclusion of a direct military conflict.

Trump said in a social media post, "The Deal with the Islamic Republic of Iran is now complete. Congratulations to all!" [2]. He said that the agreement approved the opening of the Strait of Hormuz and the lifting of the U.S. naval blockade [3].

"Let the oil flow," Trump said [1].

The deal concludes a war that has lasted between 3.5 [1] and nearly four months [4]. The conflict had severely disrupted international shipping and energy prices due to the U.S. military presence in the region.

Officials have scheduled a formal signing ceremony for Friday, June 19, 2026 [5]. The event is expected to take place in Switzerland [5], providing a neutral ground for the two nations to finalize the terms of the ceasefire.

The lifting of the blockade is the central component of the accord. By removing U.S. naval restrictions, the deal allows oil shipments to resume their normal transit through the narrow waterway [1].

“"Let the oil flow"”

The resolution of this conflict removes a primary driver of global oil price volatility. By reopening the Strait of Hormuz, the U.S. and Iran are stabilizing a critical maritime artery, though the long-term durability of the peace depends on the specific terms finalized during the Switzerland signing ceremony.
