Thirty-year fixed, 15-year fixed and 5/1 ARM rates are all lower Tuesday, according to a NerdWallet survey of mortgage rates published by national lenders this morning.

This is a volatile time for mortgage rates. Up one day, down the next. The skittish bond market may find some relief following tomorrow’s Federal Reserve short-term interest rate announcement. While a 0.25-percentage-point hike is widely expected, market analysts and bond investors will be more interested in hearing the Fed’s hint of what is coming next.

Fed Chair Janet Yellen will hold a news conference tomorrow following the rate announcement, at which time she will release the committee’s economic projections.

A warning from a mortgage rate analyst

Al Bowman watches mortgage rates every day. His company, Mortgage Commentary Services, provides analysis of mortgage rates for lenders across the nation. Noting that 10-year Treasury bond yields and mortgage rates are closely aligned, he’s alerting clients to a troubling sign.

“This week is key for bonds and mortgage rates after the benchmark 10-year Treasury Note yield closed last week at 2.46% and we open this week at 2.49%,” Bowman wrote Monday in an analysis for clients. “I have been warning about this crossroad ever since we broke above 2.25%. If this is a bad week for bonds and the 10-year breaks above 2.50%, there is little to prevent moving into the mid-2.6’s in the immediate future. And since mortgage rates track bond yields, this would equate to higher rates for mortgage shoppers.”

The current spread between 10-year Treasury yields and mortgage rates is just under 2%. For example, 10-year bonds were trading near 2.47% this morning, and 30-year mortgage rates are averaging 4.35%. As Treasury yields move higher, so do mortgage rates.

Bowman’s advice?

“Maintain contact with your mortgage professional if [you’re] still floating an interest rate and closing in the near future,” he says.
