U.S. crude inventory now at 41 days of supply—lowest in 50 years.

That's tight. Really tight.

When inventories get this lean, any supply shock (geopolitical flare-up, refinery issue, hurricane) can send oil prices spiking fast. We've seen this movie before in the 70s.

Energy names might be worth watching here. If crude stays elevated or climbs, margins for producers expand. Refiners get squeezed. Consumers feel it at the pump, which hits discretionary spending.

Not saying oil's going to $150 tomorrow, but cushion is thin. Markets don't like thin cushions.
