In this paper, we analyse the interactions between monetary and macro-prudential policies and the circumstances under which such interactions call for their coordinated implementation. We start with a review of the interdependencies between monetary and macro-prudential policies. Then, we use a DSGE model incorporating financial frictions, heterogeneous agents and housing, which is estimated for the euro area over the period 1985 -2010, to identify the circumstances under which monetary and macro-prudential policies may have compounding, neutral or conflicting impacts on price stability. We compare inflation dynamics across four “policy regimes” depending on: (a) the monetary policy objectives – that is, whether the policy instrument, the short-term interest rate factors in financial stability considerations by leaning against credit growth; and (b) the existence, or not, of an authority in charge of a financial stability objective through the implementation of macro-prudential policies that can “lean against credit” without affecting the short-term interest rate.
Our main result is that under most circumstances, macro-prudential policies have either a limited or a stabilizing effect on inflation.
