The banking industry is voicing concern that tough rules for capital and liquidity proposed by the Basel Committee on Banking Supervision would have unintended consequences. "Most of what is proposed is sensible, but our biggest concern is has anybody done the holistic analysis. If you look at parts of the proposals, they put buffers on buffers," said Pat Newberry, a financial-services expert at PricewaterhouseCoopers. "There is a very serious risk the proposals overdo the requirements. That is a big macroeconomic gamble to take. Our view is there will be changes."
