One of the reasons why macroprudential tools are not always effective, could be that vulnerabilities are not necessarily driven by the credit cycles. In the cases examined, it is evident, that credit for house purchases is not always correlated with the trends in housing prices. For example, Slovenia and the Netherlands experienced a build-up in vulnerabilities in the residential real estate market without a corresponding excessive growth in housing loans. Structural factors could explain the above observation as they affect both demand and supply of housing. More particularly, Net migration and population growth are factors that have continued to put pressure on house prices in countries such as Luxembourg, which experienced net population growth of 13,6% in 2020. Countries with low vulnerabilities in the housing market, such as Greece, experienced a negative population growth. Strong preference for home ownership could also be a driving factor for the observed vulnerabilities in Luxembourg and Slovakia. Homeowners represent 92,9% of the population of Slovakia whereas in France, a country with low identified real estate vulnerabilities, homeowners represent 65,2%. From the above examples, we can conclude that in designing a macroprudential tool, idiosyncratic structural factors need to be identified and accounted for. Monetary policy also plays a role. Although macroprudential policy is the first line of defence, the ECB has recognised that Financial Stability is a precondition for price stability. It has also been acknowledged that monetary policy, can, in principle, influence asset prices such as real estate.
Simon M Potter: Discussion of “Evaluating Monetary Policy Operational Frameworks” by Ulrich Bindseil Remarks by Mr Simon M Potter, Executive Vice President of the Markets Group of the Federal Reserve Bank of New York, at the Federal Reserve Bank of Kansas City Economic Symposium “Designing resilient monetary policy frameworks for the future”, Jackson Hole, Wyoming, 26 August 2016. *  *  *  Accompanying charts can be found at the end of the speech or on the Federal Reserve Bank of New York’s website. My thoughts on implementation issues have been enriched by numerous conversations with colleagues, particularly around the current longer-run efforts in the Federal Reserve to examine implementation. Recent dialogue with Antoine Martin was particularly helpful in producing this discussion. Introduction: what do we still need to know to evaluate operational frameworks? Thank you for giving me the opportunity to discuss Ulrich Bindseil’s excellent paper, which builds on his considerable body of work in this field and provides an insightful discussion of monetary policy implementation. What makes Ulrich’s contributions notable is the unique combination of academic rigor and practical insights he brings to the topic. By distilling the key elements of his previous research into an accessible form, this article is a useful read for anyone who wants to gain a deeper understanding of the economics of monetary policy implementation, including practitioners of central bank market operations, central bank researchers, and academics.
