Eight times per year, the Federal Open Market Committee (FOMC) meets to set the federal funds rate — the interest rate at which banks lend money to each other overnight. The decision ripples through the entire economy within days.

When the Fed raises rates, borrowing gets more expensive across the board. When it cuts rates, borrowing gets cheaper. Here's exactly what that means for the money in your life.

Your mortgage

The federal funds rate doesn't directly set mortgage rates, but it heavily influences them. When the Fed raises rates, 30-year fixed mortgage rates typically follow within weeks.

The difference is significant: a 1% increase in mortgage rates on a $400,000 home loan adds roughly $240/month to your payment — $86,000 over 30 years. This is why housing markets slow sharply when the Fed tightens policy.

If you have an adjustable-rate mortgage (ARM), your rate can reset directly when the Fed moves. Fixed-rate mortgages are insulated once locked in.

Your savings account

Here, rate hikes work in your favor. High-yield savings accounts and money market accounts track the federal funds rate closely. When the Fed raises rates from near-zero to 5%, high-yield savings accounts go from paying 0.5% to paying 4–5% APY.

On $10,000 in savings, that's the difference between $50/year and $500/year in interest — a 10× improvement from one policy shift.

Your credit card

Credit card rates are directly tied to the prime rate, which moves in lockstep with the federal funds rate. Most credit cards are variable-rate: when the Fed raises by 0.25%, your credit card APR rises by 0.25% within one billing cycle.

With average credit card debt around $6,500 per US household, a 5% increase in the fed funds rate (as happened in 2022–2023) translates to roughly $325/year in additional interest charges on that balance.

Inflation

Higher borrowing costs reduce spending, which cools price increases

Why the Fed raises and cuts rates

The Fed has two mandates: maximum employment and stable prices (2% inflation target). It raises rates to cool an overheating economy — when inflation is running hot, making money more expensive to borrow reduces spending, which reduces price pressure. It cuts rates to stimulate a slowing economy — cheaper borrowing encourages spending and investment.

Understanding this dual mandate makes Fed decisions predictable: watch the jobs report and CPI (Consumer Price Index) data. When both are running hot, rate hikes follow. When employment falls and inflation cools, rate cuts come next.
