The average U.S. price of regular-grade gasoline increased by 2 cents over the past two weeks, to $2.24 per gallon.
The report from the Illinois Economic Policy Institute concluded that road travel has dropped by nearly half and the state could lose $296 million to $559 million this year as a result.
One gas analyst says the national average price could soon dip below $2 a gallon, with some stations potentially charging as little as 99 cents.
Brent crude, the international standard, lost $9.50, or 20.1%, to $35.77 per barrel, as of 7:58 p.m. Eastern time on Sunday after earlier touching its lowest price since 2016. Benchmark U.S. crude fell $8.64 to $32.64.
