The Fed Cut Rates — Here's What It Actually Does to Your Credit Card, Car Loan and Mortgage

▶

Every Friday I do a checkup on what's happening to the dollar versus real assets, and this week the Federal Reserve cut rates by half a percentage point. The headlines immediately said "go buy a car, go buy a house." I want to slow that down and show you the actual numbers.

We'll walk through what a half-point cut does to a 24% credit card, why car loans and mortgages don't move the same way, and then look at what cash, gold, silver, Bitcoin and index funds have done since February.

What you'll learn

• How much a half-point Fed cut really lowers a 24% credit card rate
• Why car loans and personal loans barely budge — and why price matters more than rate
• Why mortgage rates track the 10-year Treasury, not the Fed
• What savings accounts, CDs and Treasuries paid versus gold, silver, Bitcoin and the S&P 500 since February
• What the 2-year/10-year yield inversion has meant historically
• How an extra $200 a month changes a $20,000 car loan

A half point off 24% is still 23.5%

Credit cards are the debt most directly tied to the Fed. It's close to one-for-one: the Fed drops half a point, your card drops about half a point. The average credit card rate is around 24%. So now it's 23.5%. Whoopee. That is not a reason to celebrate, and it is definitely not a reason to carry a balance longer.

Car loans and personal loans are not one-for-one. The average car loan is around 9% or 10%, and a cut might take it to 9% or 9.5%. That's not a signal to go buy a car — especially when cars are still overpriced. It's never just the rate. It's also the price. If homes are still overpriced, who cares what the rate is?

Mortgages follow the 10-year Treasury much more closely than the Fed funds rate. That's why mortgage rates drifted down across 2024 even though the Fed hadn't moved at all until this month.

Dollars versus assets since February

Here's the weekly checkup. On the dollar side: the national savings rate was 0.46% back in February and it's still 0.46%. A 3-month CD sat around 1.55%. Short-term Treasury yields came down from 5.42% to 5.21%. If inflation is running around 2.5% to 3%, a savings account at 0.46% is losing ground every single month.

Now the assets. Gold climbed to $2,633. Silver went from $22.88 to $31.45 — round it to $20 up to $30, that's a $10 gain on $20, a 50% jump. Bitcoin went from $43,000 to $62,000. Ethereum from $2,299 to $2,533. The Dow went from about 38,000 to 41,000 and is up roughly 21% over 12 months. The S&P 500 went from 4,958 to about 5,600, up around 30% over 12 months.

Compare that: savings 0.46%, CD about 1.5%, Treasury about 5% — silver 50%. That's why the wealthy hold assets and keep only emergency savings and short-term transaction money in dollars.

Inflation didn't reverse, it just slowed

The media points at 2.5% in August and calls it fixed. Look at the last ten years instead. We had years at 5%, 6%, 7%, 8%, 9%. That's why eggs, cars and homes cost what they cost. Slower inflation does not bring prices back down — it means prices are still going up, just less fast. We'd need significant disinflation or deflation to get back to 2021 prices, and that isn't happening.

The inversion nobody talks about

The 2-year Treasury was around 3.58% and the 10-year around 3.7%. For a long stretch the 2-year paid more than the 10-year, which makes no sense — you should get paid more to lock money up longer. Look at a five-year chart of that spread and you'll see it below zero. Historically, every time that inversion happens and then comes back out, rough economic times follow. We're coming out of one now. Markets are cyclical: they overvalue, they correct, they overvalue, they correct.

What you can actually control

You can't control the Fed. You can control your interest rate exposure. I showed the auto loan calculator: a $20,000 loan at 10% over 60 months with 12 payments made leaves 48 months. Add $200 a month and you cut 17 months off and save about $1,600. That's a bigger, more certain win than anything the Fed did this week.

Key steps

1. Ignore the rate-cut headlines. Check your actual card APR — a half point off 24% changes almost nothing.
2. Attack the highest-rate debt first with the credit card payoff calculator.
3. Find one recurring expense to cut and send that money at a loan. Run it through the auto loan early payoff calculator.
4. Keep an emergency fund in cash, but understand it's losing purchasing power to inflation.
5. Once high-interest debt is gone, put surplus into assets rather than letting dollars sit idle — see where to put money after your emergency fund is full.
6. Before buying a car or house, weigh the price, not just the rate: price vs. interest rate.

FAQ

Will a Fed rate cut lower my credit card payment?

Barely. Credit cards move close to one-for-one with the Fed, so a half-point cut takes an average 24% card to about 23.5%. On a $10,000 balance that's roughly $50 less interest over a whole year. It does not change your payoff plan.

Why didn't my mortgage rate drop when the Fed cut?

Mortgage rates track the 10-year Treasury much more closely than the Fed funds rate. That's why mortgage rates eased through 2024 while the Fed hadn't moved at all yet.

Should I buy a car now that rates are coming down?

Not automatically. Going from 10% to 9.5% is small, and cars are still expensive. What you pay matters as much as the rate you pay it at. Run both scenarios in the auto loan calculator before you decide.
