This Policy White Paper assesses several main elements of ECB’s upcoming review of its monetary policy strategy, announced in January 2020. Four aspects of the review are discussed in detail: i) ECB’s definition of price stability and the arguments for and against inflation targeting; ii) the scope of ECB’s objectives, considering financial stability, employment and the sustainability of the environment; iii) an update of ECB’s economic and monetary analyses to assess the risks to price stability; iv) the ECB’s communication practice. Furthermore, an overview of the ECB’s monetary policy strategy and its last evaluation in 2003 is given.
We study the incidence and severity of lower-bound episodes and the efficacy of three types of state-dependent policies—forward guidance about the future path of interest rates, large-scale asset purchases and spending-based fiscal stimulus—in ameliorating the adverse consequences stemming from the effective lower bound on nominal interest rates. In particular, we focus on the euro area economy and examine, using the ECB’s New Area- Wide Model, the consequences of the lower bound both for the near-term economic outlook, characterised by persistently low nominal interest rates and inflation, and in a lasting low-real-interest-rate world. Our findings suggest that, if unaddressed, the lower bound can have very substantial costs in terms of worsened macroeconomic performance. Forward guidance, if fully credible, is most powerful and can largely undo the distortionary effects due to the lower bound. A combination of imperfectly credible forward guidance, asset purchases and fiscal stimulus is almost equally effective, in particular when asset purchases enhance the credibility of the forward guidance policy via a signalling effect.
