The price of Warsh’s communications-policy shift became unmistakable at his press conference following the Fed’s most recent policy meeting last week. “There is a tension between what Warsh wants versus what the market wants,” said Bill Campbell, portfolio manager and head of global sovereign and emerging markets at DoubleLine Capital. Investors now must infer from limited guidance what the Fed chair once spelled out: how the Fed would respond to incoming data. “The market wants to be compensated for it,” he said, “and the way they get compensated is through higher interest rates.” Warsh wants rates to be driven more by markets and data rather than the committee, while the market tries to divine his reaction function.
