Could it be pay back time for the some of the bailed out big banks in the US?New York-based Goldman Sachs, JPMorgan Chase and Morgan Stanley are reported to have formally applied to repay the government cash they got to keep them afloat last October when the entire financial system seemed shaky following the collapse of Lehman Brothers. They would refund a total of 45 billion dollars (33 billion euros). By doing that they would not have to operate under the government restrictions that are part of Washington’s Troubled Asset Relief Programme, including limits on the bank bosses’ pay. Any early repayment needs to be approved by the US central bank, the Federal Reserve, which is the main regulator for all three banks. For that it would have to be satisfied that after repaying the bailout money the banks would have sufficient cash reserves.
