The 10-year Treasury yield declined after last week’s post-Brexit high in anticipation of the Fed’s September policy meeting. The 30-year fixed-rate mortgage followed Treasury yields, falling 2 basis points and settling at 3.48 percent.

The 10-year Treasury yield rose 18 basis points to 1.73 percent, its highest level since Brexit. The 30-year fixed-rate mortgage followed suit, rising 6 basis points to 3.50 percent this week. This is the first week since June that mortgage rates were above 3.48 percent, snapping an 11-week trend.

The 30-year fixed-rate mortgage fell 2 basis points to 3.44 percent this week. As mortgage rates continue to range between 3.41 and 3.48 percent, many are taking advantage of the historically low rates by refinancing. Since the Brexit vote, the refinance share of mortgage activity has remained above 60 percent.
