The central bank can never make any ex ante commitment itself in relation to an announced fiscal policy. It can never react mechanistically to a given budgetary policy. Therefore, the so-called policy mix should be the result of the ECB’s monetary policy aimed at maintaining price stability and fiscal policies in compliance with the Stability and Growth Pact.
In the context of this Pact, EU governments have agreed to reduce their government budget deficits to close to balance or even to create surpluses in the medium term. Should ministers refrain from speaking about monetary policy in public? My own preferred answer to this question, whatever it might be, is largely irrelevant.
