BRUSSELS, Sept 28 (Reuters) - A capital surcharge on large banks is not expected to become mandatory in all the world's top economies, a senior regulator said on Tuesday. Leaders from the Group of 20 countries will discuss in November what extra loss-absorbing capacity "too big to fail" banks must hold but a plan for equity capital surcharges is meeting resistance in France and elsewhere.
"Details should involve appropriate tailoring for national circumstances. It may involve a different balance in different countries," UK Financial Services Authority Chairman Adair Turner told the annual Eurofi conference on EU financial regulation.
Some countries will wish to proceed with capital surcharges while other countries will opt for using contingent capital or other measures, Turner said.
"Maybe not everyone will do an equity capital surcharge but there may be a mix of other mechanisms as well," Turner told reporters after his speech.
The world's top supervisors and central bankers agreed this month that all big banks must hold extra loss-absorbing capacity beyond the Basel III global deal on tougher capital and liquidity standards for all banks.
He added that the priority now was to translate Basel III into "robust" EU law which was more important than beefing up rules for hedge funds and curbing excessive bonuses.
Turner said EU rules on bank capital should allow national regulators to go beyond the minimum requirements.
