Stock futures were falling Tuesday and oil prices rose as Israel and Iran continued to exchange missile attacks and President Donald Trump in social-media posts urged an immediate evacuation of Tehran.

Stock futures lost ground Tuesday morning, while oil prices surged, as investors monitored developments in the escalating conflict between Israel and Iran.

Oil prices surged, stocks dropped and investors flocked to safe havens like gold on Friday after tensions between Israel and Iran escalated, stoking concerns of a broader conflict in the region.

Oil prices have resumed their upward climb and U.S. futures are lower after Israel's military issued an evacuation warning to 330,000 people in Iran's capital Tehran.

Israel's attack on Iran sparked the biggest jump in crude oil prices since Russia's invasion of Ukraine more than three years ago. Stocks fell sharply.

That sent the yield on the 10-year Treasury up to 4.43% from 4.36% late Thursday. Higher yields can tug down on prices for stocks and other investments, while making it more expensive for U.S. companies and households to borrow money.

Oil prices leaped, and stocks slumped on worries that escalating violence following Israel’s attack on Iranian nuclear and military targets could damage the flow of crude around the world, along with the global economy.

U.S. oil benchmark prices climbed roughly 7% to about $73 a barrel, the highest level since early April. U.S. government borrowing costs climbed. Tech stocks like Nvidia and Tesla moved lower, while shares in oil and defense-industry firms like Chevron, Lockheed Martin, and Palantir traded up.
