The FT reports Vickers, who led the Government’s inquiries into banking reforms, believes regulators should take much tougher action on bank capital when there are economic “blue skies” and conditions have improved.
He says banks should hold 20 per cent core tier one capital instead of the current 10 per cent requirements.
Vickers is also calling for a massive 10 per cent leverage ratio, which does not account for risk, compared to current Basel III requirements of just 3 per cent.
Labour and the parliamentary commission on banking standards both back higher leverage ratios of around 4 per cent but banks have lobbied hard against increases claiming it would hit mortgage lending.
Business secretary Vince Cable has attacked the Bank of England for its rough position, branding it the “capital Taliban” and calling for more help to boost business lending.
Vickers led the ICB which called for banks to ring-fence their retails arms from their investment divisions to prevent investment risks from affecting savers and to stop future bailouts.
