Basel 3 changes will cost banks $770 billion, study finds

New capital requirements under the Basel 3 framework would have cost banks roughly $770 billion had they been fully implemented at the end of last year, according to a 32-page study released Thursday by the Basel Committee on Banking Supervision. The study also said that the shortfall for larger banks considered to be well-diversified and internationally active was far greater than for smaller institutions when it came to meeting new capital, leverage and liquidity ratios.
