Jamie Dimon, chairman of JP Morgan Chase, has warned American investors should be more worried about the risk of default of the state of California than of Greece's current debt woes.

Mr Dimon told investors at the Wall Street bank's annual meeting that "there could be contagion" if a state the size of California, the biggest of the United States, had problems making debt repayments. "Greece itself would not be an issue for this company, nor would any other country," said Mr Dimon. "We don't really foresee the European Union coming apart." The senior banker said that JP Morgan Chase and other US rivals are largely immune from the European debt crisis, as the risks have largely been hedged.

California however poses more of a risk, given the state's $20bn (£13.1bn) budget deficit, which Governor Arnold Schwarzenegger is desperately trying to reduce. More here.  The Pew study "The Trillion Dollar Gap" is here.
