Majority of Motorists Paying More to Fill-up at the Pump this Week

More than half of all state gas price averages increased as much as three cents in the last week. The jumps, which caused the national gas price average to increase by a penny to $2.47, was caused by a decrease in U.S. gasoline stocks and increases in demand. The Energy Information Administration’s (EIA) latest data show total domestic gasoline stocks decreased by 2 million bbl to 259.1 million bbl, while demand increased from 8.72 million b/d to 8.92 million b/d. Some of the decrease in stocks can be attributed to refinery maintenance.

“Gasoline prices are likely to fluctuate in the coming weeks, but not drastically, as the winter driving season nears its end and refineries undergo maintenance,” said Marilyn Buskohl, AAA spokesperson. “This is the typical trend this time of year.”

Central States and Great Lakes Region

In the Great Lakes and Central region, Michigan ($2.45) and Missouri ($2.19) are the only states with gas price averages more expensive on the week, month and year. All other states have cheaper month-over-month prices and saw varying fluctuation in the last week.

On the week, Missouri (+10 cents), Illinois (+8 cents), Kentucky (+8 cents) and Nebraska (+6 cents) have the largest weekly increases in the region and rank among the biggest 10 jumps in the country. Meanwhile, Indiana (-6 cents) saw the largest decrease in the region and country this past week.

It’s surprising that regional gas prices jumped in the last seven days given that stocks increased by 421,000 bbl to 59.1 million – the highest stock level in a year – and refinery utilization held steady at 91%. However, volatility is typical for the region and most states only saw jumps of just a few pennies in the last week.

Oil Market Dynamics

At the close of Friday’s formal trading session on the NYMEX, WTI decreased by 50 cents to settle at $53.38. Although crude prices increased for the second week, they may not be able hold onto gains this week as concerns regarding the coronavirus continue to mount. The market continues to worry that reduced global travel and a slowdown in production in China, the world’s second largest crude consuming country, will reduce crude demand this year. Until it appears that the public health threat from the virus declines and China’s industrial sector recovers, crude prices are likely to continue facing downward pressure.
