Yields on Fannie Mae, Freddie Mac, and Government National Mortgage Association mortgage bonds rose for a fifth day Monday relative to government notes, with the spread becoming the widest in two months and potentially boosting home loan rates.

The difference between yields on Fannie's current-coupon 30-year fixed-rate mortgage securities and 10-year Treasuries widened about 4 basis points, to 207 basis points, as of 8:50 a.m. in New York, according to data compiled by Bloomberg.
