 It just wasn't enough to overcome the news out of China, a drop in oil exports from the U.S., and the uncertainty that's developed over whether or not the Federal Reserve will indeed cut interest rates before the year is out. So the NYMEX August crude contract fell 2.5% on the week, ending last week at $80.13 a barrel. That's a five-week low. The global benchmark crude, Brent, was off 2.9% to $82.63 a barrel, also a five-week low.
