This morning, Citigroup (NYSE: C) began its $58-billion stock swap, a move that could leave the government with a 34% stake in the bank. The country's third-largest bank plans to swap common stock for (up to) $33 billion in preferred shares and convert as much as $25 billion of preferred shares held by the U.S. Treasury into common stock. The bank believes that the swap could (emphasis on could here) make Citigroup one of the world's best-capitalized banks. The action could add up to $61 billion of tangible common equity and $64 billion of Tier-1 common equity. Citigroup had planned to take this action back in April.
