In a post called “Break Up the Big Banks”, Rolfe Winkler provides a nice graphic showing that the too big to fails have gotten bigger:
The big have gotten even bigger since the start of the financial crisis. At the end of 2007, the Big Four banks — Citigroup, JPMorgan Chase, Bank of America and Wells Fargo — held 32 percent of all deposits in FDIC-insured institutions. As of June 30th, it was 39 percent.
In total, they had $3.8 trillion worth of deposits as of June 30th. Compare that figure to the FDIC’s Deposit Insurance Fund, which showed a balance of just $10.4. billion on the same date.
