The Energy Information Administration (EIA) released its weekly data on diesel and gasoline retail prices for the week ended August 28, 2017. At the national level, prices for both fuels rose, although gasoline prices rose significantly more than diesel prices. Retail diesel prices increased by 0.9 cents per gallon, while gasoline prices rose by 3.9 cents per gallon.

Retail prices for refined fuels tend to track crude oil prices, but there may be a disconnect in retail price data this week and in the coming week because of the severe impacts of Hurricane Harvey, which has cut into crude runs and caused a bump-up in refined product prices. The data covered here includes the days leading up to Hurricane Harvey making landfall in Texas on Friday, plus the weekend of severe stormy weather. Heavy rains and catastrophic flooding continue to assault the region. Gasoline futures prices rose for five consecutive days until beginning to ease today.

The storm has moved back over the Gulf of Mexico, but it is expected to return with a fresh batch of moisture and make landfall tomorrow near the Texas-Louisiana border. This threatens energy infrastructure in the Houston area and along the Louisiana coast. In the Corpus Christi area, Valero and Citgo are reportedly preparing to restart their refineries.
