The price of gasoline in Idaho has risen sharply over the past week, with the statewide average now at $3.70 per gallon - a 46-cent increase from last week, 76 cents more than a month ago, and 62 cents higher than a year ago. The national average currently sits at $3.72 per gallon, up 24 cents from a week ago.

Why it matters

The steep rise in gas prices is being driven by continued volatility in the global crude oil market, with the West Texas Intermediate benchmark trading near $94 per barrel - about $31 more per barrel than just a month ago. This supply uncertainty is putting extreme pressure on pump prices across the country.
