What the Fed Does and How It Affects Your Money

On September 16, 2026, the Federal Reserve raised its target interest rate by a quarter of a percentage point, to a range of 3¾ to 4 percent. If you only saw the headline, you may have wondered what the Fed is, why it was raising rates while prices were already high, and whether any of it touches you. This post answers those three questions in order: what the Fed is and what it’s trying to do, what it did and why, and how the effect travels from a committee room to your own accounts.
Who this is for, and who it isn’t
It’s for: anyone who wants to understand the Fed well enough to read a rate headline without needing someone to translate it.
It’s not for: predicting what the Fed will do next, or timing a loan, a mortgage, or an investment around a meeting. Nobody reliably does that, and this post doesn’t try. For a shorter, wallet-level take on a rate change, see what Fed rate decisions actually mean for your wallet. This is general information, not personalized financial advice.
What the Fed is
The Federal Reserve is the central bank of the United States. The Fed describes its job as providing the nation with a safe, flexible, and stable monetary and financial system. Monetary policy, meaning the setting of interest rates and the supply of money and credit, is only one part of that, but it’s the part that makes the news.
Two groups matter here:
- The Board of Governors, seven members in Washington. The Fed says the Board is responsible for the discount rate and for reserve requirements.
- The Federal Open Market Committee (FOMC), the group that actually votes on rates. By the Fed’s description it has twelve members: the seven governors, the president of the Federal Reserve Bank of New York, and four of the other eleven Reserve Bank presidents, who rotate in for one-year terms. The FOMC holds eight regularly scheduled meetings a year.
The Fed isn’t Congress, and it doesn’t set taxes or government spending. It also doesn’t set your mortgage rate, your credit card rate, or your bank’s savings rate. It sets one very short-term rate and lets the rest of the financial system react to it.
What the Fed is trying to do
Congress has told the Fed to pursue maximum employment, stable prices, and moderate long-term interest rates. People call the first two the dual mandate, because the Fed says moderate long-term rates tend to follow when those two goals are met.
- Stable prices: the FOMC has said inflation of 2 percent a year, measured by the personal consumption expenditures (PCE) price index, is most consistent with its mandate. PCE is a different measure from the CPI number you see in most news stories, which is why the two figures often don’t match. For the CPI side, see what inflation reports actually mean for your budget.
- Maximum employment: there’s no fixed target. The Fed looks at a broad set of labor market indicators because the highest sustainable level of employment depends on things monetary policy can’t change.
The tools
- The federal funds rate target. This is the main tool. The federal funds rate is what banks charge each other to borrow reserves overnight. The FOMC sets a target range for it, and changes to that target ripple out to short-term rates, longer-term rates, asset prices, and exchange rates.
- Interest on reserve balances. The Fed pays banks interest on money they keep with it. Because a bank is unlikely to lend for less than it can earn risk-free there, changing that rate helps steer the federal funds rate toward the target.
- The balance sheet. After 2008, with the federal funds rate near zero, the Fed bought about $3.7 trillion of longer-term securities over six years to push longer-term rates down. The September 2026 statement says the Committee is continuing its policy of maintaining ample reserves in the banking system.
- Forward guidance. What the Fed says about its likely path can move longer-term rates before it does anything.
What happened on September 16, 2026
The FOMC voted 12 to 0 to raise the target range by a quarter point, to 3¾ to 4 percent. Its statement said inflation “remains elevated” and that the move would “support a timelier return to the Committee’s 2 percent goal.” It also said job gains have kept pace with the workforce and the unemployment rate has changed little.
In his press conference, Chair Warsh put the Fed’s own estimates of August total PCE inflation at about 3.6 percent over twelve months and core PCE (which leaves out food and energy) at about 3.2 percent, against a 2 percent goal, with unemployment around 4.1 percent. He described the move as removing “a dose of accommodation” so financial and credit conditions fit the Committee’s objectives.
So the Fed raised rates because inflation was above its goal and the job market was holding up, not because the economy was struggling. The next scheduled meetings are October 27 to 28 and December 8 to 9. What the Committee decides then depends on data that hasn’t been released yet, so this post won’t guess.
Why raising rates is the tool for high inflation
Higher rates make borrowing more expensive and saving more rewarding. Households and businesses tend to borrow and spend less, demand cools, and price pressure eases. The tradeoff is real: the same slowdown can reduce hiring and investment. That tension between the two goals is the reason Fed decisions get argued over, and it’s why a rate rise isn’t automatically “good” or “bad” for you. It depends on whether you mostly borrow or mostly save, and on what’s happening to your job and prices.
How a decision reaches your money
This is the part that affects your budget. The Fed’s range is for overnight interbank lending, but it anchors almost everything else. The Federal Reserve’s own H.15 data for October 13, 2026 showed the effective federal funds rate at 3.88 percent and the bank prime loan rate at 7.00 percent, exactly three points above the top of the target range.
| What | How it’s linked to the Fed | How fast it tends to move |
|---|---|---|
| Credit cards, HELOCs, other variable-rate loans | Usually priced as the prime rate plus a margin | Often within a billing cycle or two |
| Savings accounts and CDs | Banks decide; competitive online banks tend to follow | Days to months, and unevenly |
| New fixed-rate mortgages | Follow longer-term yields and expectations more than the overnight rate | Not in lockstep |
| Existing fixed-rate loans and mortgages | Locked in at signing | No change |
| Stocks, bonds, the dollar | Respond to rates and expectations about them | Immediately, and unpredictably |
| Jobs and wages | Respond to cooler or warmer demand | Slowly, over months |
The mortgage row deserves an example. On October 13 the 3-month Treasury yield was 4.26 percent and the 10-year was 5.21 percent. Long-term yields are set by markets, not by the Fed, and they’re what new mortgage rates tend to follow. That’s why a Fed move and a mortgage rate move can differ in size, timing, and even direction.
A worked example
All figures below are made up to show scale, and actual changes depend on your lender and your contract.
- Variable-rate debt. Say a quarter-point rise passes through fully to a card with a 5,000 balance carried for a year. That’s about 12.50 more in interest (5,000 × 0.0025). The card’s own rate may be far higher than the Fed’s, but the change is what a Fed move adds.
- Savings. If a bank passes a quarter-point rise through fully to 10,000 in savings, that’s about 25 more a year (10,000 × 0.0025). Many banks pass through less than the full amount, or only after a delay.
A quarter point is small on any one balance. Several increases in a row, or a large balance, make it matter.
What to do with this
- If you carry variable-rate debt, a rising-rate stretch is a good moment to prioritize paying it down. See debt payoff calculator explained for ways to model it.
- If you hold cash, check your savings rate against what other banks currently offer, because a bank doesn’t have to pass a rise on. See high-yield savings accounts explained.
- If you’re shopping for a mortgage, watch the trend over months and compare lenders, rather than reacting to one meeting.
- If you have a fixed-rate loan, nothing changes on the loan itself.
- If you invest for the long term, market swings around Fed days are normal; see what stock market volatility means for your savings.
- If you live in the euro area, the same idea works differently; see how European Central Bank rate decisions affect your money.
Common mistakes
- Assuming the Fed sets your rate. It sets one overnight rate. Your lender and the market do the rest.
- Expecting an instant change in mortgage rates. They follow longer-term yields.
- Treating “Fed raises rates” as simply good or bad. It’s good for savers and bad for borrowers, and the effects on jobs and prices take time.
- Mixing up CPI and PCE. The Fed’s 2 percent goal uses PCE, so the number in the headline may not match.
- Making big money moves on meeting day. Reactions fade; your budget and timeline matter more.
- Ignoring the fixed-vs-variable question. It decides how much a rate move touches you.
Getting started
Look at the three or four rates in your own life: any variable-rate debt, your savings account, and any loan you’re about to take. Note which ones are tied to the Fed or the prime rate and which are fixed. That tells you whether a decision matters to you, and by about how much, before the next headline lands.
