ITALIAN INSTABILITY: Investors feared the possibility of a financial crisis in Italy, the third largest economy in Europe, as well as the possibility that elections in the fall could become a referendum on Italy's use of the euro.

That means that avoiding a new euro crisis largely hinges on the hope that Italy's populist politicians don't mean what they say and won't engage in budget-busting spending if they win a new election, expected as soon as September. The dollar rose to 108.24 yen from 109.37 yen. In recent weeks, the picture has changed: the euro has lost about 7 percent since mid-April and dropped to levels not seen in 10 months as attempts to form a government in Rome floundered, thrusting Europe into crisis once again.
Economists, including at the European Central Bank, have used the price of credit default swaps on government debt in euros and dollars to gauge whether investors were betting on a country leaving the euro zone.
