That was somewhat offset by a sharp decline in gasoline demand compared with last week. Gasoline consumption fell by 570,000 barrels from a week ago, when demand was boosted by drivers hitting the road for the July Fourth holiday. Gasoline supplies rose by 3.1 million barrels last week.
Analysts had expected a decline of 2.5 million barrels in crude oil supplies and no change in gasoline supplies, according to a survey by Platts, the energy information arm of McGraw-Hill Cos.
Oil markets have also been supported this week by expectations that the Federal Reserve will support the U.S. economy as long as necessary. Fed Chairman Ben Bernanke told lawmakers that there was no preset schedule for ending the existing stimulus program, raising hopes it may not end as quickly as some had feared.
