LONDON—Oil prices wavered on Monday, as renewed concerns over waning demand in the United States and China, coupled with mixed signals from the U.S. Federal Reserve, kept markets uncertain.
Brent crude futures for January were down 8 cents at $81.35 a barrel at 0916 GMT, after losing $1 in earlier trading, while the U.S. West Texas Intermediate (WTI) crude futures for December were at $77.11, down 6 cents.
