- Abstract
- The 2019 revision to the Capital Requirements Directive allowed the systemic risk buffer to be applied on a sectoral basis in the European Union. Since then an increasing number of countries have implemented the new tool, primarily to address vulnerabilities in the residential real estate sector. To inform and foster a consistent understanding and application of the buffer, this paper proposes two specific methodologies. First, an indicator-based approach which provides an aggregate measure of cyclical vulnerabilities in the residential real estate sector and can signal a potential need to activate a sectoral buffer to address them. Second, a model-based approach following a stress test rationale simulating mortgage loan losses under adverse conditions, which can be used as a starting point for calibrating a sectoral buffer. Besides these methodological contributions, the paper conceptually discusses the interaction between the sectoral buffer and other prudential requirements and instruments, ex ante and ex post policy impact assessment, and factors guiding the possible release of the buffer. Finally, the paper considers possible future applications of sectoral buffer requirements for other types of sectoral vulnerabilities, for example in relation to commercial real estate, exposures to non-financial corporations or climate-related risks.

- Abstract
- Macroprudential policies since the global financial crisis have been central to safeguarding financial stability. Despite the increasing use of multiple policy instruments, a detailed understanding of interactions among them is still needed to assess how instrument combinations can enhance the effectiveness of macroprudential action. This paper proposes a conceptual framework for informing the choice of combinations of macroprudential instruments, looking at the role of micro and macroeconomic transmission channels, interactions across policy objectives, the importance of country specificities and linkages with other macroeconomic or supervisory policies. It also reviews considerations related to circumvention, leakages, time of activation and communication of policies, all of which may affect the desirability of different combinations of macroprudential instruments. The paper also discusses a possible operational use of combinations of macroprudential instruments to address selected risks and provides a rich analysis of instrument interactions within the categories of borrower-based and, respectively, capital-based measures. The paper concludes that the combinations of capital and borrower-based instruments ensures a comprehensive coverage of different systemic risks and entail important synergies.
