This article considers the nature of the rules that would need to exist to enable a satisfactory regulatory regime for cross-border banks in Europe in the light of the present crisis. It sets out first what would need to apply in normal circumstances when banks are sound before going to consider how earlier coordinated intervention and ultimately resolution before capital is eroded can be achieved. It suggests in particular that harmonising the detail of regulatory systems would be very time-consuming but not strike at the heart of the problem which is how countries can cooperate across legal boundaries and the structure that banks would need to have to make this feasible. It concludes by exploring the institutional structures that might make this possible, suggesting that if any new European level body is needed, the most important would be a resolution agency as demonstrated by US experience.

The growth of banks operating across national borders through branches poses problems for the regulatory and supervisory authorities, which are historically organised on a national basis, particularly in relation to their responsibility for financial stability, crisis resolution, deposit insurance and other aspects of the safety net. This article compares and contrasts two solutions to these problems that are being developed: the first by the Nordic-Baltic countries for handling Nordea, which wishes to take advantage of the European Company Statute in the legal framework of the EU/EEA, and the second by New Zealand, where most of the banks are Australian-owned. The first case reflects an attempt at a joint approach and a universalist solution that seeks greater harmonisation, while the second case reflects a territorial approach and the recognition of differences. Both show that there is already a much wider problem that needs to be addressed, even when banks operate across borders through subsidiaries. Halfway houses between internationalisation and renationalisation of responsibility seem rather less plausible routes to success, even if they are couched in terms of careful memoranda of understanding.
