The central bank and the US government have allocated trillion dollars to save the American banks at the peak of the crisis. All of it was justified by their size and systemic nature. Back then they were "too big to fail", because there was the risk of a chain collapse of the global financial system happening.

Now, the big banks have become even bigger, and just like some gigantic black holes, they are capable of distorting not just space and time, but the economic, financial and even legal environment as well.

Bloomberg recently wrote that the regulators in the US are investigating the potential involvement of the Goldman Sachs bank in manipulation the currency exchanges. Goldman Sachs joins other big names, such as JP Morgan, Citi, Barclays or HSBC, on the list of banks investigated for manipulating the markets. "No one has yet to been charged with any misdeeds", Bloomberg further writes.

Even though the reason behind the "intangibility" is more than obvious, a recent surprise can have unpredictable events in the near future.

At the "Global Economic Policy Forum", William Dudley, the president and executive director of the Federal Reserve Bank of New York spoke about the "unacceptable regime" of the financial institutions that are "too big too fail".

Before being brought by Timothy Geithner at the Federal Reserve, Dudley was the chief-economist at Goldman Sachs for ten years. But none of these was any surprise.

Even though he has reminded that the issue of "too big to fail" creates competition problems between the big banks on one side, and the medium and small ones on the other, by giving the former easier and cheaper access to financing, as well as through the perception at the investor level, of the implied government backstop, William Dudley spoke out against breaking up the major financial conglomerates.
