The Fed Raised Rates a Quarter Point. Here's What Actually Happens to Your Loan.

When the Federal Reserve raises its benchmark rate, it isn't touching your wallet directly. It's changing the price banks pay to borrow from each other overnight. But that cost doesn't stop at the bank's door — it flows downstream into every variable-rate product you hold: credit cards, home equity lines, adjustable-rate mortgages, and most auto loans issued after the hike.

Here's the part most people miss: fixed-rate mortgages signed before the hike don't change at all. The pain hits new borrowers and anyone with variable debt hardest, which is exactly why rate hikes are such a blunt instrument — they punish the person taking out a loan this month more than the person who already has one.

The mechanism is deliberate. Higher borrowing costs are supposed to make people spend less, which cools demand, which — in theory — cools inflation. Your higher car payment isn't a side effect of the policy. It is the policy.

The bottom line: If you're shopping for a loan right now, the Fed's decision this quarter matters more to your monthly payment than your own credit score improving by a few points.
