In September 2009, with unemployment at 9.5% and climbing, Warsh argued that the Fed should begin to pull back on its efforts to help the real economy recover: "if policymakers insist on waiting until the level of real activity has plainly and substantially returned to normal — and the economy has returned to self-sustaining trend growth — they will almost certainly have waited too long… There is a risk, of much debated magnitude, that the unusually high level of reserves, along with substantial liquid assets of the banking system, could fuel an unanticipated, excessive surge in lending." The runaway inflation he warned about never appeared. University of Oregon Professor Tim Duy wrote in response to the speech that it looked as though "monetary policymakers are more willing to use unconventional monetary policy to support Wall Street than Main Street."
