The global banking industry on Monday urged the Group of 20 economic powers to deliver on pledges to harmonize financial regulation, warning their commitment appears to be fraying. The Institute of International Finance said its members were "deeply troubled" by the current trend toward "increasingly fragmented financial regulation." The tendency of nations to act to protect their own financial service sectors and taxpayers against future global risk "is threatening to undo decades of cross-border cooperation," the IIF said in a statement.
