The US deal was thrashed out by Treasury Secretary Henry Paulson and Federal Reserve chairman Ben Bernanke after five days of unprecedented-turmoil that included the collapse-of investment bank Lehman Brothers, the rescue-takeovers of fellow Wall Street giant Merrill Lynch and, in Britain, of Halifax banking group HBOS, and the nationalisation of insurance giant AIG. Its disclosure-last Friday led initially to euphoria on the markets but this was quickly swept away when it emerged that many US politicians were unhappy about saddling the taxpayer with a vast burden of debt. There were also objections to the bankers who made bad loans being let off the hook by a government rescue.
