Abstract

The Covid-19 pandemic has prompted lender-of-last-resort interventions and massive asset purchases by central banks. Such responses are all the more necessary since the transmission of monetary policy to the real economy is asymmetric. Evidence suggests that the effects of an expansionary monetary policy are more limited than those of a contractionary policy. One reason lies in the existence of downward bank lending rate rigidity. Face à la pandémie de Covid-19, les interventions de prêteur en dernier ressort et les achats massifs d’actifs par les banques centrales s’imposaient d’autant plus que la transmission de la politique monétaire à l’économie réelle est asymétrique. En effet, une politique monétaire expansionniste a des effets plus limités qu’une politique restrictive, notamment en raison de la rigidité à la baisse des taux débiteurs bancaires.
