Gasoline gas prices are based on oil prices. Oil prices are determined by the oil supply and oil demand. Right now, both oil supply and oil demand are almost inelastic. As gasoline gas and oil prices go up, the demand stays almost the same. As the oil supply reaches peak oil or maximum production or extraction, the demand curve becomes vertical, or inelastic. The inelasticity of the oil supply and oil demand set things up for price volatility of both oil and gasoline. The seasonal changes in gas and oil prices we've seen in the last three years is probably due to reaching peak oil. This short screencast shows an inelastic oil supply curve, as well as an inelastic oil demand curve, and what happens to prices as the oil supply or oil demand change.
