Borrowing costs are falling—why aren't mortgage rates?

The spread has been wider than normal for two main reasons, Selma Hepp, chief economist at Cotality, tells CNBC Make It.

Inflation “remains sticky,” especially for services and shelter, she says, with overall inflation climbing back to 2.9% year over year in August — above the Fed’s 2% target. Since higher inflation erodes the value of mortgage bond payments, investors tend to seek higher yields.

And the Fed’s pullback from buying mortgage-backed securities has left private investors to fill the gap. “With less demand, [mortgage-backed security] prices fall, yields rise and mortgage rates increase. This widens the spread relative to Treasuries,” says Hepp.

Considering that the Fed’s own projections don’t have inflation reaching 2% until 2028, the “current dynamic is likely to continue,” says Christopher Hodge, chief economist for the U.S. at Natixis CIB Americas. “This has increased longer-term inflation expectations, which increases the premium demanded for mortgages.”

Those expectations help explain why Fannie Mae projects 30-year fixed rates will stay above 6% for another year, according to an updated forecast released Tuesday.
