EIA: Average diesel price falls below gasoline

On 13 July, the US average diesel fuel retail price fell below the average regular gasoline retail price for the first time since August 2009. From August 2009 through June 2015, retail diesel fuel sold at an average premium of US$0.34/gal over regular grade gasoline, with the difference reaching more than US$0.90/gal in January.

The persistent price premium for diesel compared with gasoline from August 2009 until last week reflected a combination of factors including strong global demand for diesel, federal fuel taxes for diesel that are US$0.06/gal higher than those for gasoline, and the higher production cost of ultra low sulfur diesel (ULSD) that was phased in between 2006 and 2010.

Gasoline and diesel have opposite seasonal demand patterns: gasoline demand tends to peak in the summer driving months, while diesel demand generally peaks in the winter heating months. Since January, gasoline demand growth has been unusually strong both in the US and abroad. Furthermore, although retail gasoline prices in most parts of the country have in recent weeks followed crude oil prices lower, elevated retail gasoline prices in California, as a result of ongoing supply disruptions, have raised the US weekly average gasoline retail price.

Tight diesel markets over the past six years have reflected growing diesel demand from developing economies and the switchover to ultra low sulfur diesel (ULSD) for home heating oil in northeastern states, where more than 80% of US use of oil for space heating occurs. Over the same period, gasoline demand has generally been weak, reflecting increasing vehicle fuel economy and changing consumer driving patterns.

Gasoline demand in the US began to rise considerably in the latter part of 2014 and through the first half of 2015 as US retail gasoline prices reached some of their lowest levels in years, reflecting the fall in North Sea Brent crude oil prices from an average of US$112/bbl in June 2014 to US$48/bbl in January 2015. Gasoline prices generally followed Brent crude oil prices, falling from US$3.69/gal in June 2014 to US$2.12/gal in January 2015. Based on the latest data from the Federal Highway Administration, Americans drove a record 987.8 billion miles during the first four months of 2015, topping the previous record of 965.6 billion miles set in the first four months of 2007. Global gasoline demand also increased strongly in the first half of 2015.

Price parity between gasoline and diesel is likely to be a relatively short term phenomenon, as gasoline demand moderates with the end of the summer driving season and diesel demand begins to grow in response to the fall agricultural harvest and the winter heating season. In EIA’s July Short-Term Energy Outlook (STEO), it is projected that the diesel price premium will return and gradually widen later this year, with gasoline retail prices averaging US$2.27/gal in December 2015 compared with diesel fuel prices at US$2.87/gal.
