Critical energy infrastructure in Israel and Iran has not escaped unscathed from the first few days of the countries' escalated conflict. Worst-case scenarios have yet to be realized, but the war is already having a notable impact on energy production and exports in both countries.

NEW YORK (AP) — Some calm is returning to Wall Street, and U.S. stocks are rising on Monday, while oil prices are giving back some of their initial spurts following Israel’s attack on Iranian nuclear and military targets at the end of last week.

Stock futures rebounded slightly early Monday as the spike in oil prices due to the escalating conflict between Israel and Iran eased for a moment. Stock gains were muted as investors remained concerned about the rising geopolitical risk to the global economy.

Oil prices leaped, and stocks slumped on worries that escalating violence following Israel’s attack on Iranian nuclear and military targets could damage the flow of crude around the world, along with the global economy.

Diamondback Energy stock rose 5% and Occidental Petroleum rose nearly 5% as a swathe of energy-related stocks reacted to a jump in crude prices after Israel's attack on Iran. Conoco-Phillips' stock rose 4%, ExxonMobil rose 3% and Chevron gained 2.7%.
