U.S. oil prices already jumped last week, which could cause prices at the pump to rise about 20 cents a gallon in the coming weeks, according to one estimate.

Oil prices rose again Tuesday morning in Asia, as markets weighed the odds of a resolution in the Israel-Iran conflict. Crude prices bounced as news of fresh attacks rolled in, including another wave of Iranian missiles launched at Israel and more Israeli strikes on Iran.

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.
