The gains came as U.S. President Donald Trump sharpened his rhetoric against Iran, CNBC reported. The escalation in tone from Washington coincided with the upward move in the market.
According to Al Jazeera, Bessent framed the new measures as part of an effort to economically isolate Tehran. He has not said whether countries such as China could be targeted as part of that campaign.
The rise in oil prices reflects how energy markets can react to geopolitical developments involving major oil-producing regions and to signals of intensifying economic pressure from the United States.
CNBC’s coverage of the developments referenced the Strait of Hormuz, a key waterway for global oil shipments, alongside its reporting on the Treasury Secretary’s comments and Trump’s remarks.
