Keynes argued that the short-term interest rate is the main driver of the long-term interest rate on government bonds. This paper empirically models the relationship between the short-term interest rate and long-term government securities yields in Canada, after controlling for other important financial variables. The statistical analysis uses high-frequency daily data from 1990 to 2018 to examine the behavioral dynamics of the long-term interest rate. The empirical results show that the
