One world banking system, Agrees to New Global Rules for Banks

PARIS — Central bankers and regulators have reached an almost unanimous preliminary agreement on new standards to reinforce the stability of the global financial system, adding to investors’ confidence in the outlook for many banks.

Under the new requirements, banks would have to hold more in capital reserves and more cash on their balance sheets to cushion against unexpected shocks, though regulators have not specified a minimum amount.

One country — Germany — said it needed more time to negotiate accords that it believed could put some of its lending institutions at a disadvantage.

The announcement helped banking shares move higher in Europe on Tuesday. Analysts said there was relief that the measures were not as punishing as they might have been.
