Oil surged after the US struck Iran's three main nuclear sites and threatened further attacks, exacerbating a crisis in the Middle East and stoking concerns that energy supplies from the region could be disrupted. The US assault — which targeted sites at Fordow, Natanz, and Isfahan — dramatically raises the stakes in the confrontation by increasing the premium that traders are pricing into the global energy market. The extent of the gains will hinge on how Tehran opts to respond to the US moves. For more on the burgeoning conflict, we hear from former US Ambassador to the United Nations, John Bolton. He speaks with Bloomberg's Joe Mathieu and Kailey Leinz.

Plus - US stock index futures slid ahead of the Asia session following those weekend strikes in Iran. S&P 500 futures opened nearly 1% lower before paring their loss, while contracts on the Nasdaq 100 fell nearly 1.3%. We get market insights from Gene Goldman, Chief Investment Officer at Cetera Financial Group.
