The “Viable Opposition” blog points out that the recent bull market in bonds is the third longest, measured in years, and the second largest, measured in the drop in interest rates since 1285.
While the interest rate on the 10-year treasury bond is roughly 1% higher than it was 6 months ago, this is a small rise compared to the 1.79% increase experienced over just four months in 1994. And, from 1965 to 1970, the ten year yield increased from 4.17% to 8.05%.
None of this is to predict what will happen in interest rates, just to give a sense of the scale of changes that could take place.
