Some commentators have said that in a crisis stronger coordination between monetary and fiscal policy is desirable, even if it comes at the expense of reducing the independence of monetary policy. The opposite is actually true. Especially in a crisis the responsibilities for monetary policy and for fiscal policy have to remain quite separate.
The reason is that it is precisely during a crisis that the fiscal authorities try to push the central bank towards solving the fiscal problem through the inflation tax. However, the central bank is protected from this pressure by its statutes and the rules it adopts for the conduct of monetary policy.
