The Iranian attack hit the Ras Laffan terminal for shipping out liquefied natural gas in Qatar. Qatar normally supplies some 20% of the world’s consumption of LNG, which can be carried by ship. The facility shut down after a drone attack. The closure of the Strait of Hormuz to most tanker traffic also left the gas with nowhere to go.
If the disruptions from Iran’s attacks on its Gulf Arab neighbors’ energy infrastructure keep oil and gas prices high for long, they could create a debilitating wave of inflation for the global economy.
