The Federal Open Market Committee (FOMC) is the policy-making arm of the Federal Reserve. It determines short-term interest rates in the U.S. when it decides the overnight rate that banks pay each other for borrowing reserves when a bank has a shortfall in required reserves. This rate is the fed funds rate. The FOMC also determines whether the Fed should add or subtract liquidity in credit markets separately from that related to changes in the fed funds rate. The Fed announces its policy decision (typically whether to change the fed funds target rate) at the end of each FOMC meeting. This is the FOMC announcement. The announcement also includes brief comments on the FOMC's views on the economy and how many FOMC members voted for and how many voted against the policy decision.
Why Investors Care
The Fed closely monitors the core PCE price index to indicate whether or not policy is approximately correct, overly accommodative, or too restrictive. The PCE price index is preferred to the CPI because it is more closely aligned to the cost of living than the CPI (which measures a fixed basket of goods & services.)
This chart covers monthly data and the fed funds target rate reflects the monthly average. As such, it will not correspond to the most recent fed funds rate target announced by the Fed.
