The FOMC effectively decides upon two short-term interest rates at each meeting: the discount rate (the rate at which eligible banks borrow from the Fed), and the federal funds rate (the rate at which banks make overnight loans to each other).1
Changes in the discount rate are implemented quickly…
Changing the discount rate is relatively simple: Discount rates are established by each Reserve Bank’s board of directors every two weeks, subject to review and determination by the Board of Governors.2 Therefore, changes in the discount rate go into effect right away or soon thereafter. You can check the dates of discount rate changes at the following Fed website.
… while the implementation of changes in the federal funds rate is a bit trickier.
The fed funds rate chosen by the FOMC is simply a target, meaning the Federal Reserve has to buy and sell U.S. Treasury securities to achieve the target rate in the market for bank reserves. In other words, the FOMC chooses the target for the federal funds rate (in essence, the price of available bank reserves), but obtains that price by adjusting the quantity of funds available.3 For example, to lower the fed funds rate, the Fed will instruct the open market desk in New York to purchase Treasury securities on the open market, which in turn infuses money into the banking system and thus moves the effective federal funds rate or price of those reserves down.
Once the targeted fed funds rate is reached, the job isn’t done because the open market is dynamic. The amount of money people carry changes from day to day according to seasonal factors, interest rates, and changes in their income; therefore, the supply of bank reserves changes too. In this dynamic environment, the Fed continues adjusting the supply of bank reserves from the first trading day after an FOMC meeting until a change in the target federal funds rate is determined at a future FOMC meeting.
How does the Fed know what quantity of Treasury securities to buy or sell to achieve the targeted federal funds rate? The answer is through a very detailed process, implemented as follows:4
- Following an FOMC meeting, the Committee issues a directive to the open market desk outlining its targeted federal funds rate.
- The manager of the Open Market Account then translates the FOMC’s directive into operating objectives by working with Federal Reserve staff in New York and at the Board of Governors in Washington, D.C. These staffs develop reserve objectives they think will set the market for bank reserves at the targeted fed funds rate. Based on detailed forecasts of the demand for reserves and the anticipated level of discount window borrowing, they create a nonborrowed reserve (NBR) “path,” or objective, for each two-week period over which banks’ required reserves are maintained.
- This NBR objective is updated continuously during each two-week period as projections of the demand for reserves are revised.5 The NBR reserve objectives, together with estimates of the supply of NBR, serve as the core elements for judging reserve conditions and for conducting day-to-day open market operations.
As shown in Chart 1, you can see that the effective fed funds rate generally comes quite close to its target fed funds rate through this process—you can hardly differentiate between the two lines! (You can view the data at the New York Fed’s Federal Funds Data site).
The FOMC policy statement – another tool of monetary policy
Even though the Fed can’t flip a switch to automatically change the federal funds rate, it has taken steps to immediately communicate to markets its targeted changes in the fed funds rate. The FOMC releases a statement at roughly 2:15 p.m. Eastern time following each FOMC meeting to inform the general public of its monetary policy decision, regardless of whether or not rates have been changed.
This statement has become very significant in recent years, and many view the statement itself as an additional monetary policy instrument. The wording and message contained in the statement lets the markets know what monetary policy decision was made, what factors the FOMC considered in making that decision, and what are its immediate concerns about the economy and monetary policy. The statement is very brief, but consists of several parts: the decision of the committee, the rationale for that decision, a discussion of balance of risks, a brief discussion of the future policy actions, a vote record, and the discount rate decision. (View past FOMC statements on the Board of Governors website.)
How does the release of the FOMC statement serve as an additional policy instrument? In short, it greatly enhances the Fed’s transparency, which makes monetary policy more effective and more precise. In a 2004 speech, then-Fed Governor (now Chairman) Ben Bernanke explained that transparency has this effect in three ways:
- In the short run, it increases near-term predictability of FOMC decisions, helping the market to smoothly adjust to changes in monetary policy with few large disturbances.
- In the long-run, it helps anchor the public’s expectations (most importantly, inflation expectations).
- Overall, it helps align expectations of financial markets’ participants with the FOMC’s own plans and projections.
Markets watch the release of the FOMC statement very closely. San Francisco Fed President Janet Yellen stated in a 2006 speech that, since the FOMC began releasing a post-meeting statement in 1994, “financial markets have become much better at forecasting the future path of monetary policy than they were up to the late 1980s, and are more certain of their forecast ex ante as measured by implied volatilities from options contracts.”
