Global markets steadied Tuesday after days of volatility tied to the war with Iran, while oil prices eased back toward $90 a barrel after briefly nearing $120. U.S. stock futures edged higher as investors weighed mixed signals from President Donald Trump and ongoing attacks in the region. Oil remains about 34% higher since the conflict began, pushing U.S. gas prices up to $3.54 a gallon and keeping concerns high about disruptions in the Strait of Hormuz.
