Mortgage market update: what moved over the last 10 days, and what it means for your buying power
Mortgage rates don't take their cue from the Fed. They follow the bond market, especially the 10-year Treasury. And bonds have had a rough stretch.
Here's what happened:
→ Jobs came in hot (Sept 4). Employers added 162,000 jobs in August when economists expected about 53,000. Unemployment held at 4.1%. A stronger economy usually pushes bond yields up, and mortgage rates go up with them.
→ Oil broke $100 a barrel on U.S.–Iran tensions, which brought inflation worries back.
→ Wholesale inflation rose 0.4% in August (Sept 10). A big jump in diesel prices drove most of it.
→ The 10-year Treasury yield pushed toward 5%, its highest level since 2023. Mortgage rates followed. Freddie Mac's weekly average ticked up again this week and is well above where it was a year ago.
This morning's inflation report (CPI):
Consumer prices rose 0.4% for the month and 3.4% over the past year, in line with forecasts
Gasoline alone jumped 3.9% in August and accounted for more than a third of the increase
Core inflation (excluding food and energy) rose 0.3%, a bit cooler than the 0.4% economists expected
Translation: Right now the inflation problem is mostly energy. The underlying trend didn't get worse, which is the first bit of good news bonds have had in a while.
What's next: The Fed meets Sept 15–16, and markets see a real chance of a rate hike. It sounds backwards, but a Fed that looks serious about inflation can actually calm the bond market, and the bond market is what drives mortgage rates. Expect some swings either way.
What this means for your purchasing power Small rate moves add up. For example, if rates rise a quarter point from today's range, the same monthly principal-and-interest budget buys about 2.5% less home. On a $400,000 loan, that's roughly $10,000 in buying power. It works the same way in reverse when rates come down.
So the best move right now isn't guessing where rates go next. It's knowing your own numbers so you're ready when the market gives you an opening.
