The euro slid against both the yen and the dollar as investors reacted badly to an unproductive European Union meeting in Poland.

A cancellation of a visit by Greek Prime Minister George Papandreou to the United States to chair an emergency meeting and a regional election defeat for Germany's chancellor Angela Merkel added fuel to an already tense euro.

After investors pushed the safe-haven Swissie up some 20 percent against the euro within the space of just a few months, on Sept. 6 the SNB implemented a cap on the franc at 1.20 per euro.

So far that ceiling has held, though some market participants have warned that a worsening of the euro zone debt crisis could lead speculators to test the SNB's resolve to defend that level.

"Euro/Swiss is glued to a reading just above 1.20. Technicals favour a higher dollar/Swiss from here," said UBS economist Reto Huenerwadel in a note.

The franc rose 0.2 percent against the dollar to trade at 1.2066 by 0738 GMT compared to the New York close.

The franc was flat against the euro.
