Basel II is a set of rules that could change how banks are regulated and managed globally. A survey found that over 90 countries plan to adopt Basel II, but many supervisors will need more training. Implementing Basel II could cause disagreements between countries on how to regulate banks with operations in multiple places. In some countries, the new rules might not work well with their current banking practices, which could harm their economies. The changes from Basel II could also affect international trade in banking services.
