The U.S. Energy Information Administration (EIA) released its weekly data on diesel and gasoline retail prices for the week ended June 3, 2019. Gasoline prices fell for the fourth week in a row. Diesel prices also declined. On a national average basis, retail prices for both gasoline and diesel fell by 1.5 cents/gallon. National average prices for gasoline were 13.3 cents/gallon below where they were in the same week one year ago. National average prices for diesel were 14.9 cents/gallon lower than they were in the same week last year.

Futures Prices and Retail Price Outlook

During the week May 28-May 31, 2019, West Texas Intermediate (WTI) crude futures prices dropped by $2.48/b (4.2%.) Gasoline futures prices dropped sharply by 9.01 cents/gallon (4.6%.) Diesel futures prices also fell significantly by 6.3 cents/gallon (3.183%.) Although the relationship between futures market prices and retail prices is not immediate and one-for-one, the most recent trend in futures prices suggests that gasoline and diesel retail prices will continue to fall in the coming week. However, regional markets should watch for increases in ethanol prices and gasoline price volatility, because of severe weather. U.S. corn crop plantings are behind schedule, and ethanol production and distribution is expected to be heavily impacted this year.
