Gasoline prices jumped in over three-quarters of U.S. states over the last week, as oil prices surged following President Trump's decision to reduce tariffs and strike new trade deals. The move inspired optimism that a major tariff-induced economic slowdown might be avoided. Average gasoline prices in Minnesota have risen 13.3 cents per gallon in the last week, averaging $3.02. The national average price of gasoline has risen 6.1 cents per gallon, averaging $3.14. The national average price of diesel has increased 2.9 cents in the last week and stands at $3.50 per gallon.
