In that context of extended need for cooperation and coordination among regulators and supervisors, my last comment is related to the levers at hand to promote trust and reliance on foreign supervisors to prevent the development of a trend towards ring fencing and the risk of market fragmentation. Let me say first that I don’t think that promoting mutual trust and reliance among supervisors can move us to a world free of ring fencing. This is because it has its root and it is the result of the trade-off each regulator and supervisor has to face, in normal time and during crisis, between the need to preserve the stability of financial intermediaries or the financial system as a whole for which it is accountable and the need to preserve their competitiveness through their integration to the global financial system. For instance, for banks with cross-border activities, regulators and supervisors need to balance requirements for pre-positioning of capital and liquidity in their jurisdiction and the need to leave to those banks enough flexibility in the management of those resources at group level. And this without mentioning the development of idiosyncratic financial stability risk which might call for macroprudential approach and specific additional capital requirements at a country level, and might add to the complexity to maintain this delicate balance.
Denis Beau: Financial supervisory and coordination - new issues and challenges  regulatory  policy  Contribution to the panel discussion by Mr Denis Beau, First Deputy Governor of the Bank of France, at the Salzburg Global Finance Forum, 22 June 2021. * * * Regulatory policy and Supervisory coordination has always been fraught with challenges. I remember panel discussions with market participants about this very topic at the BIS twenty years ago. No surprise for me that it is still a topic today, because there is a deeply rooted reason for it: the inevitable tension between market forces on the one hand, which push for a borderless financial system in many of its layers, despite step backwards, as we have seen since the Global financial crisis, and on the other hand the jurisdictions in which regulators and supervisors operate, are accountable and must discharge their obligations, which at best are regional for some and most often are national. This observation does not mean that we have not made progress in addressing this tension over the last decades. Nevertheless, I would differentiate between coordination issues to manage large-scale crisis and to prevent those crisis. Regarding the former, I think it is fair to say that the Covid-19 pandemic acted as a test of the resilience of our global coordination framework, which has improved with a strong G20 dimension after the GFC.
