LONDON—Oil prices dipped on Friday, with benchmarks heading for their weakest monthly performances since November, ahead of key U.S. inflation data which could give clues on future interest rate moves and the strength of the dollar.
Brent futures, which have risen nearly 5 percent this week, were down 63 cents, or 0.8 percent, at $78.64 a barrel at 0824 GMT. U.S. West Texas Intermediate (WTI) crude fell 44 cents, or 0.5 percent, to $73.93, having gained about 7 percent so far this week.
