Crude prices in New York fell 1 percent to $135.37 a barrel.
"There's just been such a build-up in oil prices and hawkish talk from the Fed that when that number printed today -- and it was in-line on the core -- it really took the heat off the interest rate markets and the Fed," said Jim Paulsen, chief investment officer at Wells Capital Management in Minneapolis.
