Wall Street rallies, Dow ends with record on US-Iran deal, oil price slide

Wall Street experienced a significant rally on June 15, 2026, with the Dow Jones Industrial Average reaching a record high following the announcement of an interim peace deal between the United States and Iran. This agreement is anticipated to facilitate the reopening of the strategically vital Strait of Hormuz, which has implications for global oil supply and market stability.

The surge in the Dow reflects heightened investor optimism, as the peace deal is seen as a crucial step toward easing geopolitical tensions that have historically impacted market performance. The positive sentiment is further supported by rising stock indices across Europe, including the FTSE 100 and STOXX 600.

This development underscores a broader trend of improving market conditions in response to geopolitical resolutions, as seen in the significant rallies in both U.S. and European markets. The easing of tensions between the U.S. and Iran may also alleviate inflation fears, contributing to a decline in global bond yields and a more favorable investment climate.
