Swiss franc falls from 15-month high

The euro suffered its fourth weekly loss versus the dollar and yen on concern budget deficits in Greece and other European nations will hamper the region's economic recovery.

The 16-nation currency on Friday tumbled to an almost one-year low against the yen and to the weakest level in eight months versus the dollar as investors bet sovereign risk crises in nations such as Greece, Portugal and Spain will force policymakers to keep interest rates at record lows for longer.

The Swiss franc fell from its highest level in 15 months against the euro as traders speculated the nation's central bank sold the currency to curb its strength.
