Oil prices were lower today on nerves about central bank monetary policy. The market is afraid that central banks are not done hiking rates yet. Both contracts are trading broadly within a $10 range traced since early May. Oanda analyst Craig Erlam said prices were mainly at the mercy of “the ever-changing expectations for interest rates.” “Despite concerns for the slowing economy in Europe, they are going to put the pedal to the metal with interest rates and that puts pressure to the downside,” said Phil Flynn, an analyst at Price Futures Group. In the United States, U.S. consumer confidence increased in June to the highest level in nearly 1-1/2 years amid renewed labor market optimism. WTI traded down $1.67 or -2.4% to close at $67.70. Brent traded down $1.92 or -2.6% to close at $72.26
