Nout Wellink, chairman of the Basel Committee on Banking Supervision, said the Basel III capital and liquidity rules for banks could be adjusted for the European sector. "What is very important is that we stick as much as possible to original proposals," Wellink said. "There might be some adjustments based on specific situations in Europe." He also said he is confident that the U.S. will adopt the rules. "I trust they will deliver, but there's always a parliament which can delay processes," Wellink said.
