As widely expected, the Fed increased the federal funds target rate this week for the third time in 2017. The market had already priced in the rate hike so long-term interest rates, including mortgage rates, hardly moved. Mortgage rates have been in a holding pattern for the fourth quarter, remaining within a 10 basis point range since October.

This week’s survey reflects last week’s uptick in long-term interest rates, with the 30-year fixed mortgage rate up 4 basis points to 3.94 percent. The 30-year mortgage rate has been bouncing around in a 10 basis point range since September.

While long-term rates have been relatively steady week-to-week, shorter term interest rates have been on the rise. The spread between the 30-year fixed mortgage and the 5/1 Hybrid ARM rate was 59 basis points this week, down 43 basis points from earlier this year. With a narrower spread between fixed and adjustable mortgage rates, more borrowers are opting for a fixed product.

The market implied probability of a Fed rate hike in December neared 100 percent, helping to drive short term interest rates higher. The 5/1 Hybrid ARM, which is more sensitive to short-term rates than the 30-year fixed mortgage, increased 10 basis points to 3.32 percent in this week’s survey. The spread between the 30-year fixed mortgage and 5/1 Hybrid ARM is just 58 basis points this week, the lowest spread since November of 2012.
