FED Paper Examines Impact of Governance Structures on CCyB Decisions
FED published a paper that examines whether governance structures for macro-prudential policies affect decisions to implement Basel III macro-prudential capital buffers. The paper presents empirical evidence that stronger governance for macro-prudential policies significantly increases the probability of using the countercyclical capital buffer (CCyB). The analysis also shows that stronger governance increases the sensitivity of this probability to credit growth, consistent with taking actions to mitigate financial stability risks.
The study finds that the probabilities of using CCyB are higher in countries that have financial stability committees with stronger governance mechanisms and fewer agencies, which reduces coordination problems. The probability of the use of CCyB by a country is even higher when financial stability committees or ministry of finance have direct authority to set the CCyB; this might be because setting the CCyB involves establishing a new macro-financial analytical process to regularly assess systemic risks and allows these new entities to influence the traditional process of writing rules. The study finds that only some of the new multi-agency committees—specifically, those with tools or those with fewer member agencies—are consistent with a functional delegation motive. While countries may prefer to create these committees mainly for improved communication, large committees or those with weak governance mechanisms may actually hinder effective decision-making.
The study also shows that the institutional arrangements and establishing clear responsibilities for new tools have a measurable effect on decisions. New authorities with tools and accountability can have a significant effect on using the CCyB. The study does not find that central banks with direct powers are more likely than independent bank regulators to use the CCyB or increase the minimum systemically important bank surcharge, although central banks are involved in multiple ways in these decisions. For the CCyB, they are the direct authority in 34 countries (wherever they are also the prudential regulator) and they make formal recommendations in five more countries. However, the study does not find a distinct effect for the central bank from the prudential regulator for any of the macro-prudential capital buffer decisions.
