The Basel III rules aren’t even law yet in any country, yet bank chief executives are under pressure from investors to explain how they will deliver a commercial return on equity under the new rules by 2013/14.

Instead, they have tried to convince investors they can reach their capital and return-on-equity targets organically, through retained earnings and deleveraging.
