Average 30-year mortgage rate climbs to 6.66%, highest in a year

What This is

• Freddie Mac reports the average 30-year fixed mortgage rate rose to 6.66%, the highest level in a year.
• The 15-year fixed mortgage rate has also risen to about 6.0% in the same period.
• Several outlets also put the 30-year average closer to 6.58% to 6.76%, showing small week-to-week differences in reported averages.
• A major driver is the rise in the 10-year Treasury yield, which tends to move in the same direction as mortgage rates.
• Higher oil prices tied to the Iran conflict have increased inflation worries, which has helped push up Treasury yields and mortgage rates.
• The Federal Reserve has held its benchmark interest rate steady, but some officials favored a hike and markets are watching for possible tightening later.
• Higher mortgage rates are already cooling parts of the housing market, including weaker mortgage applications and slower home sales activity.
• Some forecasts expect mortgage rates to stay in the mid- to high-6% range, or edge higher, into fall 2026 unless inflation and geopolitical risks ease.

Why This Matters

• Even small rate moves can add hundreds of dollars a month to a typical payment, pricing some buyers out or forcing them into smaller homes and longer commutes.
• Higher rates can lock in today’s owners at low rates, cutting the number of homes for sale and keeping prices firm even when demand cools.
• Mortgage rates spread financial stress beyond housing, because buyers may delay other spending and builders may slow projects when borrowing gets expensive.
• The gap between wages and housing costs can widen, raising fairness concerns when wealthier households can pay cash or rely on family help.
