Figure 2 shows that the two-year Treasury yield’s sensitivity to news was less attenuated than that of the three-month yield. For example, in 2003–04, the two-year yield closely followed its normal tendency in response to news, implying that it was relatively unaffected by the FOMC’s implicit lower bound of about 1%. Thus, it is reasonable to conclude that monetary policy’s effectiveness on the two-year Treasury yield was essentially normal in 2003–04.
