Gas prices have fallen 9% from their peak this summer, in a good sign for inflation

• The average price for a gallon of gas has fallen to about $3.50, according to data from GasBuddy.
• That's good news for inflation, as investors and consumers are both hoping that price increases continue to dissipate.
• GasBuddy attributed the 9% decline in gasoline prices since early September to a seasonal drop in demand.

In a welcome sign to both consumers and investors, gasoline prices are falling.

The decline means consumers are set to save some money at the pump, while investors should have one less component of inflation to worry about.
