Stock futures are pointing to a higher open for major U.S. indexes on Monday as investors monitor developments in the ongoing conflict between Israel and Iran.

Global shares have advanced and oil prices have fallen back slightly as Iran unleashed a fresh wave of missile attacks on Israel early Monday.

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.

Israel has targeted Iranian energy infrastructure, including the world’s largest gas field, South Pars, which Iran shares with Qatar. CNN’s Becky Anderson speaks with analyst Firas Maksad about how this escalation poses a significant threat to global energy security.

An exchange of strikes on refineries and gas facilities was limited but raised the risks to an industry with broad economic impacts.

Israel’s attack on Iranian nuclear and military sites on Friday, and the resulting oil-price surge and airline-stock slump, could pose even more obstacles for consumers navigating an already unusual summer travel season.
