The greatest risk the oil markets face is that Iran retaliates against Israel airstrikes by closing the Strait of Hormuz, which is critical to global energy shipments.

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.

A weekend of retaliatory missile strikes between Iran and Israel leaves the area facing fears of a broader conflict, pushing oil prices near year-to-date highs.
