This paper evaluates the macroeconomic effects of macroprudential policy measures consisting of changes in loan-to-value ratios in the euro area. The analysis is carried out within a fully structural, multi-country model, that prominently includes nancial frictions and a banking sector. Our main findings suggest that a permanent LTV tightening in a small euro area economy leads to a long-run decline in lending to the private sector. The short-run impact depends crucially on the policy design, being less pronounced when the measure is phased-in. This is consistent with policy goals of curbing credit growth but avoiding an abrupt immediate contraction in lending. A policy measure introduced at the euro area level implies larger long-run e ects but the short-run recessionary impact is attenuated by the monetary policy response.
