Crude dips, gasoline spikes as floods knock out almost a quarter of US refineries

Oil prices dipped on Wednesday but gasoline spiked to its highest since mid-2015 as flooding in the wake of Hurricane Harvey knocked out almost a quarter of US refineries, crimping demand for crude but raising fears of fuel shortages.

Harvey, which has been downgraded to a storm, has caused massive floods across coastal Texas, including in Houston. It is now moving into Louisiana, where more floods are expected.

“Catastrophic and life-threatening flooding continues in southeastern Texas and portions of southwestern Louisiana,” the National Hurricane Center (NHC) said in its latest note.

US West Texas Intermediate (WTI) crude futures were at $46.35 per barrel at 0644 GMT, down 9 cents from their last close. Brent crude futures were down 6 cents, at $51.94 a barrel.

Refined products

In the refined product market, price movements have been more dramatic.

US gasoline prices were over 3 per cent higher at $1.8380 per gallon. Prices earlier climbed to the most since July 31, 2015, at $1.842. Diesel futures also jumped, gaining 1.2 per cent to $1.6854 a barrel and were earlier at their highest since January 9 at $1.697.

“As of August 29, we estimate US refining production offline was 4.1 million barrels per day (bpd); this represents 23 per cent of total US refining production,” Goldman Sachs said in a note to clients.

Goldman also said around 1.4 million bpd of crude production was disrupted, equivalent to 15 per cent of total US output.

NHC alert

The NHC said the next 24 hours would remain dangerous.

“There is a danger of life-threatening inundation, from rising water moving inland from the coastline, during the next 12 to 24 hours,” the NHC said, adding that 6 to 12 inches of rain could fall in far east Texas and southwestern Louisiana.

The largest refinery in the United States, Motiva Enterprises' 603,000 barrel-per-day (bpd) plant in Port Arthur, Texas, was shutting down on Tuesday night because of flooding.

Preparing for more rain and floods, Total has cut production in half at its 225,500 bpd refinery, also in Port Arthur.

Restarting plants even under good conditions can take weeks. Harvey has also delayed loading of liquefied natural gas (LNG) at Cheniere's Sabine Pass in Louisiana, the only US LNG export terminal.

Crude inventories

Beyond the impact of Harvey, the American Petroleum Institute (API) had said on Tuesday that US crude inventories fell by 5.780 million barrels last week, an indicator that the US oil market is gradually tightening.

The figures, however, do not reflect the impact from Harvey. Government data for last week is due to be published by the Energy Information Administration (EIA) later on Wednesday.

Traders said that EIA data would take weeks to fully reflect the impact of the storm and floods.
