The Federal Reserve: What It Is and What It Does

A steel-blue bank, graphite balance scale and three silver spheres symbolize the Fed's goals and individual rate projections.

Two headlines, one fictional Fed meeting: “Fed raises target from 4.75–5.00% to 5.00–5.25%” and “Officials expect cuts later.”

Both can be true on the same afternoon. The first reports a decision; the second describes what officials think will fit the economy if it develops as they expect. Neither tells your mortgage lender what rate to charge.

What the Fed is trying to do

The Federal Reserve, or Fed, is the US central bank. It runs monetary policy: influencing the cost and availability of money and credit to support the economy.

Taxes and government spending belong to fiscal policy, decided at the US federal level by Congress and the administration.

Congress gives the Fed two main goals: maximum employment and stable prices. Together they are called the dual mandate. Maximum employment is the highest employment the economy can sustain alongside stable prices. People still take time to find jobs, so it does not mean zero unemployment.

For price stability, the Fed aims for 2% inflation over the longer run, measured by the annual change in the overall personal consumption expenditures (PCE) price index.

Those goals can pull in different directions. Cooling demand to restrain inflation can also slow hiring, and the effects take time. The Fed has influence over the economy, not a dial for every price.

The Federal Open Market Committee, or FOMC, decides the direction of monetary policy. It brings together members of the Fed's Board of Governors and regional Reserve Bank presidents.

A target range and a traded rate

Banks keep money in accounts at the Fed. Those deposits are reserve balances, often called reserves. Federal funds are overnight loans of these balances between banks and other eligible institutions.

The federal funds rate is the interest rate on those loans, quoted per year even though the borrowing lasts overnight.

The FOMC chooses a target range, the band it wants that rate to trade within. In our headline, both ends move:

ItemBeforeAfter
Lower bound4.75%5.00%
Upper bound5.00%5.25%

Both endpoints rise by 0.25 percentage points, or 25 basis points. The band moves up without getting wider.

To steer trading into that band, the Fed mainly uses administered rates: rates it sets directly. The key one is interest on reserve balances, the return banks earn on money held at the Fed.

Banks compare this return with what they could earn by lending overnight. Raising it makes cheap lending less attractive and helps pull market rates higher. Other administered rates and market operations support the process.

The effective federal funds rate, published by the New York Fed, summarizes actual overnight trades. Say it reads 5.08% after our decision. That sits inside 5.00–5.25%.

A target tells you what the Fed wants; the effective rate tells you where the market traded.

Read the decision before the dots

The FOMC has eight regularly scheduled meetings a year and can act between them. Its releases have different jobs:

  • Statement and press conference. The statement announces the decision and reasons; the chair explains it and takes questions. An accompanying implementation note gives the operational details and effective date.
  • Summary of Economic Projections, or SEP. Released quarterly, it collects participants' economic outlooks and their views of appropriate policy.
  • Minutes. Released three weeks after each scheduled decision, they give a fuller account of the discussion behind it.

The dot plot sits inside the SEP. Each dot shows the policy rate one participant thinks will fit their economic outlook. It includes officials who do not vote at that meeting. The year-end rates mark the middle of a preferred target range, or a single target rate.

Take three made-up year-end projections: 4.0%, 4.5% and 5.0%. The middle value, or median, is 4.5%. The lowest and highest views are 5.0% − 4.0% = 1.0 percentage point apart. One headline number hides that disagreement.

A median is not an agreed plan. The three dots count three opinions, not three equally likely outcomes.

The dots have no names, so you cannot connect them across years to trace a particular official's path. A year-end dot also leaves the route open: several different sequences of meetings could end at the same rate.

An official can support a hike at one meeting and favor cuts later if inflation cools. The committee still has to make each decision as the data arrive.

Why the wording can move markets

Suppose investors expected a 50-basis-point hike and got 25. Rates have risen, but by less than expected. The same 25-basis-point hike would carry different news if investors had expected no change.

The surprise is the gap between the announcement and the expectation.

Even an expected decision can come with unexpected words about future policy. What officials say about the path ahead can matter more than the move just announced.

Read a Fed announcement in this order:

  1. Decision and effective date. Find the target range in the statement and its start date in the implementation note.
  2. Reasons and risks. Read what changed in the committee's view of inflation and employment.
  3. Projections and uncertainty. Look at participants' views of future rates and the economic outlook behind them.

For a stockholder, the next question is how that policy change reaches company cash and valuations.

In short

  • The Fed pursues maximum employment and stable prices in the United States.
  • The FOMC chooses a target range; the effective federal funds rate summarizes actual market trading.
  • The return banks can earn at the Fed helps steer overnight market rates, alongside supporting tools.
  • The dots are conditional individual projections, not promised rate moves.
  • A policy announcement matters relative to what investors expected.
