Oil prices were lower today on worries that global oil demand growth could be hit by a stronger dollar and negative economic news from some parts of the world. The dollar rose to a 7 week high today. In the world’s biggest oil consumer, U.S. business activity crept up to a 26-month high in June amid a rebound in employment, but price pressures subsided considerably, offering hope that a recent slowdown in inflation was likely to be sustained. “Signs of stronger demand in Asia also boosted sentiment. Oil refineries across the region are bringing back some idled capacity after maintenance,” analysts at ANZ Research said. WTI traded down $.56 or -.7% to close at $80.73. Brent traded down $.47 or 0.6% to close at $85.24.
