NEW YORK, June 24 (Reuters) - The dollar rose against the Swiss franc on Wednesday as traders reported the Swiss National Bank was intervening in the market by selling the Swiss currency for dollars and euros.
The dollar was the biggest beneficiary of the intervention reports, on which the SNB declined to comment.
"It appears they have stepped up the aggressiveness of their intervention," said Marc Chandler, global head of currency strategy at Brown Brothers Harriman, in a note.
"Although actual confirmation remains elusive, it appears that the SNB or through a multilateral institution, are on the bid rather than just accepting offers."
The dollar, however, pared gains after a government report showed U.S. durable goods orders unexpectedly rose 1.8 percent in May.
The data provided further evidence that the battered economy was finding its feet and eroded safe-haven demand for the greenback.
"Definitely a big surprise for the market and we're seeing dollar selling across the board except against the yen," said Brian Kim, currency strategist at UBS in Stamford, Connecticut.
"The data is another positive sign for the U.S. economy and people may be revisiting the 'green shoots' theory once again," he added.
In early New York trading, the dollar hit a high of 1.0910 francs from around 1.0660 francs before the reports emerged. The dollar was last up 1.3 percent at 1.0813 francs, up 1.4 percent on the day.
Traders cited the SNB buying dollars around 1.0880 francs. Earlier, market players cited the Bank for International Settlements buying euros on behalf of the SNB around 1.5125 francs, after it was seen in the market earlier at around 1.5010/15 francs. The BIS declined to comment.
The euro extended gains to rise as high as 1.5288 francs, its highest in more than two months, from around 1.5010 francs before the intervention reports. It was last at 1.5192, up 1.2 percent.
The euro last traded down 0.2 percent at $1.4052, while the dollar was up 0.1 percent at 95.28 yen.
Market participants awaited an announcement by the Federal Reserve's policy-setting Federal Open Market Committee at the end of its two-day meeting, at about 2:15 p.m. EDT (1815 GMT).
The Fed is widely expected by economists to leave the benchmark federal funds rate at almost zero. Investors will focus on what the Fed says about the economic outlook and its debt-buying program.
