The world's largest banks need to raise around €577bn in capital to comply with new global regulatory standards, the Bank for International Settlements said on Thursday.

In a survey published alongside the official texts of its new rules on capital and liquidity standards, the BIS concluded that "Group 1" banks across the world--that is those with over €3bn in capital--would need a total of €177bn in extra capital just to meet the new absolute minimum capital adequacy ratio of 4.5%.
