Introduction to U.S. Economy: Monetary Policy


The Federal Reserve (Fed), the nation's central bank, is
responsible for monetary policy. This In Focus explains
how monetary  policy works. Typically, when the Fed wants
to stimulate the economy, it makes policy more
expansionary by reducing short-term interest rates. When it
wants to make policy more contractionary or tighter, it
raises rates. Since September 2024, the Fed has been
reducing interest rates, reversing some of the early interest
rate hikes it had implemented in an attempt to reduce
inflation. For background on the Fed and its other
responsibilities, see CRS In Focus IF10054, Introduction to
Financial Services: The Federal Reserve.

Federa Open Market Committee
Monetary policy decisions are made by the Federal Open
Market Committee  (FOMC),  whose voting members are the
Fed's seven governors, the New York Federal Reserve
Bank president, and four other reserve bank presidents, who
vote on a rotating basis. The FOMC is chaired by the Fed
chair. FOMC  meetings are regularly scheduled every six
weeks, but the chair sometimes calls unscheduled meetings.
After these meetings, the FOMC statement announcing any
changes to monetary policy is released.

Statutory Goals
In 1977, the Fed was statutorily mandated to set monetary
policy to promote the goals of maximum employment,
stable prices, and moderate long-term interest rates. The
first two goals are referred to as the dual mandate. The dual
mandate provides the Fed with discretion on how to
interpret maximum employment  and stable prices and how
to set monetary policy to achieve those goals. There are no
formal repercussions when goals are not met.

Since 2012, the FOMC has explained how it carries out its
mandate in its Statement on Longer-Run Goals. It defines
stable prices as 2% inflation, measured as the annual
percent change in the personal consumption expenditures
price index. In the FOMC's view, maximum employment
is not directly measurable and changes over time owing
largely to nonmonetary factors that affect the structure and
dynamics of the labor market. In 2025, the Fed will
conduct a review of the Statement. Some have questioned
whether 2020 revisions to the Statement contributed to the
Fed's slow response to high post-pandemic inflation.

Federal Funds Rate
In normal economic conditions, the Fed's primary
instrument for setting monetary policy is the federal funds
rate (FFR), the overnight interest rate in the federal funds
market, a private market where banks lend to each other.
The FOMC   sets a target range for the FFR that is 0.25
percentage points wide and uses its policy tools (discussed


below) to keep the actual FFR within that range. (The
current FFR target can be found on the Fed's website.)

Monetary Policy and the Economy
Changes in the FFR target lead to changes in interest rates
throughout the economy, although these changes are mostly
less than one-to-one. Changes in interest rates affect overall
economic activity by changing the demand for interest-
sensitive spending (goods and services that are bought on
credit). The main categories of interest-sensitive spending
are business physical capital investment (e.g., plant and
equipment), consumer durables (e.g., automobiles,
appliances), and residential investment (new housing
construction). All else equal, higher interest rates reduce-
and lower rates increase-interest-sensitive spending.

Interest rates also influence the demand for exports and
imports by affecting the value of the dollar. All else equal,
higher interest rates increase net foreign capital inflows as
U.S. assets become more attractive relative to foreign
assets. To purchase U.S. assets, foreigners must first
purchase U.S. dollars, pushing up the value of the dollar.
When  the value of the dollar rises, the price of foreign
imports declines relative to U.S. import-competing goods,
and U.S. exports become more expensive relative to foreign
goods. As a result, net exports (exports less imports)
decrease. When interest rates fall, all of these factors work
in reverse and net exports increase, all else equal.

Business investment, consumer durables, residential
investment, and net exports are all components of gross
domestic product (GDP). Thus, if expansionary monetary
policy causes interest-sensitive spending to rise, it increases
GDP  in the short run. This increases employment, as more
workers are hired to meet increased demand for goods and
services. An increase in spending also puts upward pressure
on inflation. Contractionary monetary policy has the
opposite effect on GDP, employment, and inflation. The
Fed chooses whether to make monetary policy
expansionary or contractionary based on how employment
and inflation are performing compared to its statutory
goals-expansionary  policy can boost employment but
risks spurring inflation, while contractionary policy can
constrain inflation but risks decreasing employment.

Most economists believe that although monetary policy can
permanently change the inflation rate, it cannot
permanently change the level or growth rate of GDP,
because long-run GDP is determined by the economy's
productive capacity (the size of the labor force, capital
stock, and so on). If monetary policy pushes demand above
what the economy can produce, then inflation should
eventually rise to restore equilibrium. The Fed can
preemptively change interest rates to take into account the
