10Y T 30Y M yield spread, nyse trading volume (图)

10Y T 30Y M yield spread normally 1.6%, now 2.6% The following is a comparison between the 30 year mortgage rate and the ten year treasury yield. Usually mortgage rates follow the shorter duration Ten Year treasury yield (with a spread), because most homeowners either sell or refinance before 10 years. The period that a homeowner holds a mortgage does vary over time and that does impact the spread between the 30 year rate and the ten year treasury - so it's not a perfect relationship, but it is pretty close.
