Oil prices fall as market weighs mixed supply signals | Reuters

Oil prices slipped on Thursday amid thin trading volumes ahead of a public holiday, as traders weighed a larger-than-expected build in U.S. oil stocks against tightening global supply.

Brent futures were down $1.14, or 1.1%, at $107.64 a barrel, while U.S. West Texas Intermediate futures were off $1.32, or 1.3%, at $102.93 a barrel at 0632 GMT.

Both contracts on Wednesday had shrugged off a large build in U.S. crude inventories to end the trading session roughly 4% higher.

"Asian buyers have been absent today, with volumes potentially being curbed by the long weekend across most of Asia, Europe, and North America," OANDA analyst Jeffrey Halley wrote in a note.
