$150 oil isn't some abstract market chart problem, it's a policy choice with a body count. If crude stays anywhere near that level, central banks will get blamed for inflation they can't drill their way out of, and regular people will get hit twice: at the pump and then again when rate hikes cool wages and hiring. Europe is more exposed, sure, but the US isn't insulated if diesel spikes and transport costs bleed into groceries. My take is governments should be talking windfall taxes and direct relief now, not acting like "energy security" just means cutting climate rules and praying Saudi Arabia saves us.
