Mortgage Rates Edge Up to 6.66%, Pushing Monthly Payments Higher
MarketsFN Data Team
The 30-year fixed mortgage rate rose slightly to 6.66% this week, up 0.01 percentage points, adding pressure to homebuyers as monthly payments on a $400,000 loan now cost $87 more than a year ago.
The 30-year rate remains above its 3-month (6.56%), 1-year (6.32%), and 5-year (6.14%) averages, hovering near its 52-week high of 6.69%. A $400,000 mortgage now costs $2,571 monthly, up from $2,484 a year ago when rates were lower. The 15-year rate also climbed to 5.98%, up 0.03 percentage points.
Mortgage rates are tracking the 10-year Treasury yield, which sits at 4.79%, while the Fed Funds Rate holds at 3.63%. The wide 1.87-percentage-point mortgage-Treasury spread reflects lenders' cautious stance amid economic uncertainty and inflation concerns.
Next week, watch for Fed commentary on rate cuts and key jobs data, which could sway Treasury yields. Seasonal cooling in housing demand may ease rate pressure, but stubborn inflation could keep borrowing costs elevated.
