As Israel and Iran exchanged more attacks, stock markets mostly rose even as worries remained about possible oil supply interruptions.

Oil prices fell and stocks climbed in early trading on Monday, indicating optimism among investors about the limits of economic fallout from the ongoing Israel-Iran conflict. The Dow Jones Industrial Average surged 415 points, or 1%, erasing much of the losses suffered on Friday as back-and-forth strikes broke out between the two countries.

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.
