What the Federal Reserve does

In short

A neighbor of mine once asked why her car loan rate moved when nobody in her town had done a thing. The answer had a lot to do with a group of people in Washington who meet on a set schedule. You can use this without ever meeting them. Watch the rate your own bank pays on savings, since it can follow the Fed's lead, and ask any lender whether your loan rate is fixed or can change. Write down which of your payments would move if rates rose, and by how many dollars. Read the plain statement the Fed posts after each meeting, and skip the loud commentary. Remember this. The Fed sets one short term rate, and it does not set the price of your groceries, your house, or your stock.

The whole of it

What it is

I once watched an old farmer check the weather by squinting at the sky, and he never claimed he could change it. The Federal Reserve is a bit like that, though it does have a few real levers. Congress created it in 1913 through the Federal Reserve Act, and it serves as the central bank of the United States. A central bank is a bank for banks, and it also helps steer the whole money system.

You have probably heard the Fed described as one big thing. It is really a few pieces. There is a Board of Governors in Washington, whose members the President names and the Senate confirms. There are twelve regional Reserve Banks spread across the country, each tied to the folks in its own part of the map. And there is the Federal Open Market Committee, which people call the FOMC, and that committee votes on the main interest rate decisions.

Congress gave the Fed two big jobs, often called the dual mandate. One is maximum employment, meaning as many people working as the economy can sustain. The other is stable prices, meaning inflation stays low and steady. The law also mentions moderate long term interest rates. The Fed has a third job that gets less attention, which is helping keep the banking system safe and the payment system running. Quiet work, but it matters.

How it works

A friend of mine who runs a hardware store says he thinks of the Fed as the folks who set the price of borrowing money overnight. That is close enough to true. Banks lend each other money for a single night to meet their reserve needs. The rate on those loans is called the federal funds rate. The FOMC sets a target range for it, and the Fed uses several tools to keep the real rate inside that range.

If you are holding a credit card, a car loan, or a savings account, here is why this matters to you. When the Fed raises its target, borrowing tends to cost more across the economy. When it lowers the target, borrowing tends to cost less. Higher rates cool spending and can slow inflation. Lower rates warm spending and can help hiring. Think of a thermostat, though a slow one, since the effect can take months to show up. Patience helps.

The Fed has other tools too. It can buy or sell government securities, which are basically loans to the U.S. government. Buying them adds money to the system, and selling them pulls money out. After the 2008 crisis and again in 2020, the Fed bought very large amounts of securities to hold down longer term rates, and people call this quantitative easing. When the Fed lets those holdings shrink, people call it quantitative tightening. It also sets a discount rate, which is the rate it charges banks that borrow from it directly, and it can change the reserve rules banks follow.

One more point deserves a plain word. The Fed does not print your paycheck or set what the store charges for eggs. It nudges borrowing costs, and the rest of the economy moves in its own ways. Prices also respond to weather, wars, supply chains, and thousands of ordinary choices made by people who never heard of the FOMC.

The numbers, and where to find yours

I never trust a number until I know where it came from. So here is where to look. The Federal Reserve posts the current federal funds target range on its own website, federalreserve.gov, in the statement released after each FOMC meeting. As of the latest verified figure, the target range is the current figure, which the official source publishes each year. The site fills that in with its source and date, so please check the date before you lean on it.

The Fed has stated a long run inflation goal of the current figure, which the official source publishes each year percent. The Bureau of Economic Analysis publishes the index the Fed uses to measure it, called the price index for personal consumption expenditures. The Bureau of Labor Statistics publishes the Consumer Price Index, which is the one you hear about most in the news. Those are two different yardsticks, and they can give different readings.

The FOMC meets the current figure, which the official source publishes each year times a year on a published schedule. You can find that calendar on federalreserve.gov. After each meeting the Fed posts a short statement, and a few weeks later it posts detailed minutes. Reading the statement takes about two minutes. It beats an hour of guessing.

A worked example

A woman I will call Denise took out a car loan last year for 20,000 dollars. Her loan has a variable rate, meaning the rate can move with market rates. Suppose her rate rose from 6 percent to 7 percent after a stretch of Fed rate hikes. Here are her numbers, with every input shown.

A simple way to see the cost is to look at one year of interest, ignoring the slow payoff of the loan. At 6 percent, the interest on 20,000 dollars is 20,000 times 0.06, which is 1,200 dollars. At 7 percent, it is 20,000 times 0.07, which is 1,400 dollars. The difference is 1,400 minus 1,200, or 200 dollars a year.

This is a rough picture only. Her real bill would shrink as she paid the loan down, so the true extra cost would be a little less than 200 dollars. Still, it shows the point. One extra percentage point on a 20,000 dollar balance adds about 200 dollars over a year.

Now look at the other side. Denise also keeps 5,000 dollars in a savings account. Suppose her bank raised that rate from 1 percent to 2 percent. At 1 percent she earned 5,000 times 0.01, which is 50 dollars. At 2 percent she earns 5,000 times 0.02, which is 100 dollars. That is 100 minus 50, or 50 dollars more in a year. So the rise helped her a little on savings and cost her more on the loan. Her friend had a fixed rate loan and felt none of it. That small difference is worth knowing before you sign anything.

Where it goes wrong

I have made my share of mistakes reading the weather, and I would not be too proud to say so. The most common slip is thinking the Fed controls everything. It does not. It sets one short term rate and uses a few other tools. Mortgage rates, for example, follow longer term market forces and can move in ways the Fed did not plan.

Another slip is expecting quick results. Rate changes work slowly, and the Fed can misjudge how much or how fast, so inflation can stay high longer than hoped, or a slowdown can arrive sooner than expected. The people at the Fed work with imperfect data, like the rest of us. Give them a little grace, and give yourself some too.

A third slip is treating every headline as a signal to act. Rate news is loud. Your own plan should be quiet and steady. Nothing here tells you to buy, sell, or hold anything. It only explains how the machinery works and what borrowing costs.

Last, watch for fixed versus variable. If you did not know which kind of rate your loan carries, that is worth ten minutes today.

Questions to answer before you leave this page

Do you know whether each loan you carry has a fixed rate or a variable one, and what your credit card rate is right now? What does your savings account pay today, and when did your bank last change it? Have you looked at the federal funds target range on federalreserve.gov and noted the date beside it? Which of your monthly payments would move if rates rose by one percentage point, and by how many dollars? How would you see the cost of a rate change in your own budget, and what would you want to know first? And when the next FOMC meeting comes, will you read the plain statement instead of the noise around it?
