Mortgage rates have run up so far and so fast this year that many would-be homebuyers can no longer afford to buy a home.
By fall, mortgage rates had more than doubled, eventually topping 7% in October.
When Treasury yields go up, so do mortgage rates; when they go down, mortgage rates tend to follow.
“We have to remember mortgage rates come down much slower than they go up,” said Cohn.
“Volatility increases the level of mortgage rates, compared to Treasury rates, because of the prepayment option,” said Chester Spatt, professor of finance at Carnegie Mellon University’s Tepper School of Business.
