Episode notes
Global Oil Market Sets Local Gas Prices
- Gasoline prices at the pump are set largely by the global crude oil market, with crude making up over half the pump price.
- Sam Ory explains local taxes, distribution, marketing, and refinery differences then add to that base and cause regional variation.
Rockets And Parachutes Explain Pump Stickiness
- Gas prices rise fast and fall slowly — a 'rockets and parachutes' pattern observed in research.
- Sam Ory says stations price based on expected cost of their next load and unsold higher-cost inventory slows downward moves.
U.S. Production Doesn’t Make The Market Isolated
- Even U.S. oil production can't fully insulate domestic prices because refineries require different crude types.
- Sam Ory notes the U.S. exports light sweet crude and imports heavier sour crude to match refinery configurations.
