By MarketWatch TOKYO (MarketWatch) - The dollar rose against major rivals in Asian trading Wednesday, getting a lift on cross-trading as the euro sank to an all-time low against the Swiss franc amid ongoing fears of fallout from Greece's debt problems. The euro reportedly slid as low as 1.4232 Swiss francs on the EBS trading platform, and as low as 1.4229 francs according to FactSet data. It was recently trading at 1.4246 francs, down 0.1%. Traders say the Swiss National Bank has intervened on several occasions over the past year in an effort to slow the appreciation of the franc against the euro, but has apparently stopped doing so recently. Earlier this month, the central bank repeated a pledge to make further interventions, if needed, to prevent an "excessive" rise by its currency against the euro, surprising traders who had expected the bank to soften its stance.

The SNB's Wednesday absence in markets as the Swiss franc plunged "may well be in response to the fact that based on the U.S. Treasury's mechanistic approach to ranking currency manipulation, it is arguably the case Switzerland has a higher chance of being named a manipulator than China in the 15 April 2010 U.S. Treasury report on International Exchange rate policy," said Sue Trinh, senior currency strategist at Royal Bank of Canada, in a note to clients. Against the dollar, the euro fell to $1.3414 from $1.3512 in late North American trading on Tuesday. The British pound traded at $1.4968, down from $1.5041. The dollar index (DXY 81.11, +0.21, +0.26%) , which measures the greenback against a trade-weighted basket of six major currencies, rose to 81.231 from 80.825 late Tuesday. The dollar rose to 90.55 Japanese yen from 90.42 yen late Tuesday. On Tuesday, the dollar rose against the euro and a basket of its rivals as ongoing uncertainty over European Union aid for Greece weighed on investors' minds. See Tuesday's Currencies report.
