The 10-year Treasury yield rose about 10 basis points this week. The 30-year mortgage rate moved with Treasury yields, rising 6 basis points to 4.03 percent.

The 30-year mortgage rate fell 11 basis points this week to 3.97 percent, dropping below the psychologically-important 4 percent level for the first time since November. Weak economic data and growing international tensions are driving investors out of riskier sectors and into Treasury securities. This shift in investment sentiment has propelled rates lower.

Following a weak March jobs report, the 10-year Treasury yield dropped about 5 basis points. The 30-year mortgage rate fell 2 basis points to 4.08 percent. Not only did the average 30-year fixed-rate mortgage decline for the fourth consecutive week, it also fell to a new 2017 low.
