The Swiss franc fell against all of its most-traded counterparts on speculation the central bank sold the currency to stem its advance. The dollar gained versus the euro, erasing earlier losses as traders closed their bets against the greenback on speculation the Swiss National Bank intervened. “Official names and SNB came in to the market heavily,” said Sebastien Galy, a currency strategist at BNP Paribas Securities SA in New York. “They intervened on a trade-weighted basis, buying dollar-Swiss and euro-Swiss.” The franc depreciated as much as 1.6 percent to 1.5287 versus the euro before trading at 1.52 at 8:11 a.m. in New York, compared with 1.5017 yesterday. The Swiss currency slid as much as 2.1 percent to 1.0908 against the dollar, from 1.0667. The declines were the biggest since March 12, when the Swiss National Bank said it intervened. An SNB spokesman, Nicolas Haymoz, declined to comment on whether the banks took action in foreign-exchange markets today. Basel, Switzerland-based Bank for International Settlements spokeswoman Lisa Weekes also declined to comment. The U.S. currency advanced 0.4 percent to $1.4016 against the euro from $1.4027 yesterday. The dollar gained 0.3 percent to 95.50 yen from 95.22.
