Fixed-rate mortgages this week dropped to their lowest averages of the year, which analysts attribute to the fallout from last week’s “Brexit” vote. The 30-year fixed-rate mortgage averaged 3.48 percent this week, only 17 basis points from its all-time record low of 3.31 percent in November 2012, Freddie Mac reports.

“In the wake of the Brexit vote, the yield on the 10-year U.S. Treasury bond plummeted 24 basis points,” says Sean Becketti, Freddie Mac’s chief economist. “This extremely low mortgage rate should support solid home sales and refinancing volume this summer.”

Freddie Mac reports the following national averages for the week ending June 30:

  • 30-year fixed-rate mortgages: averaged 3.48 percent, with an average 0.5 point, falling from last week’s 3.56 percent average. Last year at this time, 30-year rates averaged 4.08 percent.
  • 15-year fixed-rate mortgages: averaged 2.78 percent, with an average 0.4 point, dropping from last week’s 2.83 percent average. Last year at this time, 15-year rates averaged 3.24 percent.
  • 5-year hybrid adjustable-rate mortgages: averaged 2.70 percent, with an average 0.5 point, falling from last week’s 2.74 percent average. A year ago, 5-year ARMs averaged 2.99 percent.
