Political Crises in Italy, US Causing Investors To Worry

Shutdown looming in the U.S., while in Italy ministers from Berlusconi's party have left the governing coalition

Deadlock in the U.S. Congress has made it increasingly possible the government will run out of money from midnight, while a split in Italy's ruling coalition has heightened the prospects of fresh elections that could delay economic reforms.

Ten-year Italian government bond yields jumped 31 basis points to 4.73 percent.

"We have a bit of a nasty combination of U.S. and Italian political problems," said Arne Lohmann Rasmussen, head of FX research at Danske Bank.
