As supervisors, we must always strive to minimize these differences and reduce burden on bankers as they conduct business across national borders. However, bankers must also realize that national boundaries still matter, and that some differences in capital requirements across countries will remain.
While there may be opportunities here and there to reduce burden through broad policy changes, generally the most productive way to address crossborder issues is on a case-by-case basis. In most cases, blanket assurances are neither feasible nor realistic.
