Speaking in San Francisco on Thursday, Dallas Fed President Richard Fisher said he expects "a change of course in monetary policy to occur sooner rather than later, even in the face of an anemic economic scenario."

"I would expect a change of course in monetary policy to occur sooner rather than later, even in the face of an anemic economic scenario," he said. "Inflation is the most insidious enemy of capitalism. No central banker can countenance it, not least the men and women of the Federal Reserve."

Fisher also said that inflation was a concern for the entire FOMC committee and not just himself.
