Quantitative Easing and the Term Premium as a Monetary Policy Instrument
Résumé
The transmission of Quantitative Easing to aggregate macroeconomic variables through the yield curve is disentangled in two yield channels: the term premium channel, captured by a term premium series, and the signaling channel, that corresponds to the interest rate expectations counterpart. Both yield components are extracted from a term structure model and plugged into a Structural VAR with Euro Area macroeconomic variables in which shocks are identified using sign restrictions. With this set-up, I show how the central bank can use the term premium as a single monetary policy instrument to foster output and prices. However, I also show that there has been a cost channel in the transmission of QE to inflation between 2015 and 2017. This cost channel provides a new explanation as to why inflation has been so muted during this period, despite the easing monetary environment. Finally, a policy rule for the term premium is estimated.
