Mortgage rates’ rise has led to wide gap with US bond yields

LOS ANGELES (AP) — Economists are baffled by a wider-than-usual divergence between long-term mortgage rates and the yield on the benchmark U.S. government bond that is driving a sharp rise in borrowing costs and helping to torpedo the U.S. housing market this year. This spread has historically averaged around 170 basis points a month, but between March and October it averaged about 240 basis points, according to Federal Reserve data. In October, the spread widened to 292 points, the biggest monthly gap since August 1986.
