Thirty-year fixed mortgage rates are higher Thursday, while 15-year fixed and 5/1 ARM rates are unchanged, according to a survey of national lenders by NerdWallet.

“Post-Brexit volatility tapered off over the last two weeks, allowing interest rates to bounce back a bit from their record (10-year Treasury yield) and near-record (30-year mortgage rate) lows,” Sean Becketti, chief economist for Freddie Mac, said in a news release. “This week, the 30-year fixed mortgage rate increased 3 basis points to a still-quite-low 3.45%. With the Federal Reserve on hold and the U.K. monetary authority taking at least a one-month breather, we don’t expect any significant movement in mortgage rates in the near term.”
