US long-term mortgage rates up for 6th week; 30-year at 6.7%

The average rate on 15-year, fixed-rate mortgages, popular among those looking to refinance their homes, jumped to 5.96% from 5.44% last week.

Rapidly rising mortgage rates threaten to sideline even more homebuyers after more than doubling in 2022. Last year, prospective homebuyers were looking at rates well below 3%.

Freddie Mac noted that for a typical mortgage amount, a borrower who locked in at the higher end of the range of weekly rates over the past year would pay several hundred dollars more than a borrower who locked in at the lower end of the range.

Last week, the Federal Reserve bumped its benchmark borrowing rate by another three-quarters of a point in an effort to constrain the economy, its fifth increase this year and third consecutive 0.75 percentage point increase.

Perhaps nowhere else is the effect of the Fed's action more apparent than the housing sector. Existing home sales have been in decline for seven straight months as the rising cost to borrow money puts homes out of reach for more people.

The government reported Thursday that the U.S. economy, battered by surging consumer prices and rising interest rates, shrank at a 0.6% annual rate from April through June. That was unchanged from the previous estimate for the second quarter.

Fed officials forecast that they will further raise their benchmark rate to roughly 4.4% by year's end, a full point higher than they envisioned as recently as June. And they expect to raise the rate again next year, to about 4.6%. That would be the highest level since 2007.

By raising borrowing rates, the Fed makes it costlier to take out a mortgage and an auto or business loan. Consumers and businesses then presumably borrow and spend less, cooling the economy and slowing inflation.

Mortgage rates don't necessarily mirror the Fed's rate increases, but tend to track the yield on the 10-year Treasury note. That's influenced by a variety of factors, including investors' expectations for future inflation and global demand for U.S. Treasurys.
