Oil prices rise as US-Iran peace talks stall

Asian shares and Wall Street indexes edged higher on May 22 as oil prices moved up amid doubts that US-Iran peace talks would produce a breakthrough.

The two sides remain split over Iran’s uranium stockpile and control of the Strait of Hormuz, a chokepoint that helps set the cost of global energy supplies and broader market expectations.

Market View

Traders treated any progress in US-Iran talks as a reason to ease oil risk, but the lack of a clear deal kept prices supported. Investors also weighed how any shift in Hormuz tensions could affect shipping and inflation worldwide.

US-Iran Negotiating View

Officials on both sides have signaled some movement, but they remain at odds over the scale of Iran’s uranium stockpile and who controls access around the Strait of Hormuz. That leaves the talks in a fragile position, with each side still pressing its core demands.

  • The Strait of Hormuz is only about 33 kilometers wide at its narrowest point.
  • Oil prices often move before broader markets because they affect transport, manufacturing, and inflation.
  • Tokyo is a major price-setting center for Asian market opening reactions.

US-Iran Ceasefire War

The United States launched military strikes against Iran on June 26, 2026, in response to a drone attack on a commercial cargo ship in the Strait of Hormuz, calling it a "foolish violation" of the 60-day ceasefire agreement signed just days earlier[2][4][14].
