In response to problems in financial markets and a slowing economy, the Federal Open Market Committee (FOMC) began lowering its target for the federal funds rate from 5.25 percent in September 2007. Over the next year, the FOMC cut its federal funds rate target in a series of steps. Economist Price Fishback of the University of Arizona observed, "The Fed has been pouring more money into the banking system by cutting the target federal funds rate to 0 to 0.25 percent in December 2008." What is the relationship between the federal funds rate falling and the money supply increasing? How does lowering the target for the federal funds rate "pour money" into the banking system?
