FORT WAYNE, Ind. (WOWO): Gasoline prices increased last week in almost all 50 states. Patrick DeHaan with GasBuddy says the spike is likely due to a sudden jump in the price of crude oil tied to speculation of a change or freeze in oil output.

DeHaan adds that, while drivers are used to typically seeing gas prices racing higher in the spring, the direct impact of this weekend’s speculation could cause gasoline prices this week to reverse temporarily as oil markets react.

In Fort Wayne, average retail gasoline prices have risen 1.6 cents per gallon in the past week, averaging $2.06 per gallon Sunday. This compares with the national average that has increased 6.9 cents per gallon.
