Gas Prices Increase as Market Transitions to Summer Blend Gasoline

April 2, 2018 - Gas prices are edging up across the country as the market continues to purge winter-blend gasoline to make room for summer storage. At $2.66, the national gas price average is 5-cents more expensive on the week and 11-cents more expensive than two weeks ago.

“Today, only 38 percent of U.S. gas stations are selling gasoline for $2.50 or less and that percentage will likely dwindle in coming weeks,” said Marilyn Buskohl, AAA South Dakota spokesperson. “The holiday weekend, strong demand and preparation for summer gasoline are all factors that have driven and will continue to drive higher gas prices into early spring.”

Gas prices are more expensive on the week across the Great Lakes and Central region with three states landing on this week top 10 list with the biggest increases: Kentucky (+10 cents), Missouri (+9 cents) and Indiana (+7 cents). Nebraska ($2.56) was the only state in the region to see no change at the pump this week. 

Kentucky (+37 cents) and Indiana (+35 cents) are the leading states in the region with the largest year-over-year increase. Ohio (+17 cents) has the region’s and country’s lowest year-over-year difference in gas prices. 

With a nearly 500,000 bbl draw, gasoline inventories continue to sit above the 58 million bbl mark. The region carries the second-highest inventory level in the country – second to the South and Southeast’s 84 million bbl.

Oil market dynamics

The NYMEX was closed on Friday due to the holiday. On Thursday, WTI increased 56 cents to settle at $64.94. The increase was led by Baker Hughes active rig count report that revealed the U.S. dropped seven active rigs last week, bringing the total to 797.
