How the Federal Reserve Moves Your Money

One committee in Washington sets a single interest rate — and it quietly reprices your savings account, your mortgage, and the stock market.

Eight times a year, the Federal Open Market Committee meets to decide one number: the target range for the federal funds rate, the rate banks charge each other for overnight loans. It sounds obscure. It is arguably the most consequential price in the world.

The mechanism is simple in outline. When the Fed raises the funds rate, every other interest rate in the economy tends to rise with it — because lenders always have the option of parking money risk-free overnight, so anything riskier has to pay more. Savings yields climb, but so do mortgage rates, credit card APRs, and the cost for companies to borrow and expand.

Why the Fed does it

Congress gives the Fed a dual mandate: stable prices and maximum employment. When inflation runs hot, the Fed raises rates to cool demand — borrowing gets expensive, spending slows, price pressure eases. When the economy stalls, it cuts rates to make money cheap and coax spending and hiring back to life.

The blunt truth is that the Fed manages the economy by making money more or less painful to borrow. It cannot fix supply chains or build houses; it can only lean on demand.

What it means for your accounts

Savings: high-yield savings accounts and money-market funds track the funds rate closely, usually within weeks of a change. When you see headlines about a cut, expect your yield to drift down soon after.

Mortgages: fixed mortgage rates follow the 10-year Treasury yield more than the funds rate itself, and Treasuries move on where markets expect the Fed to go. That is why mortgage rates often move before the Fed actually acts.

Stocks: lower rates make future company profits worth more today and push savers toward riskier assets, which is why markets hang on every word of the Fed chair's press conference. The reaction is rarely about the decision itself — usually well telegraphed — and almost always about the hints on what comes next.

How to read a Fed headline

Three phrases do most of the work. A hike or cut is the action. The dot plot is the committee's own projection of where rates go next. And guidance — words like "patient," "data-dependent," or "restrictive for some time" — is the Fed steering expectations without moving at all. Markets trade on all three, and the last one most of all.
