NEW YORK, March 11 (Reuters) - The dollar rose against the euro on Thursday after seeing a smaller-than-expected U.S. trade deficit, with trading volatile as investors first drove up the euro on increased risk appetite then sold the currency after it failed to break recent ranges.
The U.S. trade deficit shrank to $37.29 billion in January from a revised $39.9 billion in December, government data showed. For details, see [
]. Economists were expecting a deficit of $41 billion.A separate government report showed the number of U.S. workers filing new applications for unemployment insurance were slightly higher than expected last week, hinting at a slow labor market recovery. [
].The Swiss franc fell after the Swiss National Bank said it would act "decisively" to counter any excessive rise in the Swiss franc.
"Initially there was a knee-jerk reaction to the better-than-expected U.S. trade report," said Michael Woolfolk, BNY Mellon currency strategist. "What is good for the U.S. is good for risk appetite. Now, there is not enough juice in the report to test the upside range" on the euro.
In early New York trade, the euro was down 0.2 percent at $1.3626 <EUR=>. The session peak was $1.3687 with a low of $1.3620.
Woolfolk said the euro is stuck in a range of $1.3500 to $1.3700.
Greece may also have been weighing on the euro after German Chancellor Angela Merkel said the first priority for Greece was to win back the confidence of financial markets, and the debt-stricken country's first steps were a positive start.
"Confidence in the markets and in the euro can only be regained when Greece itself makes (Greece) work," Merkel said. [
]"There's a perception that the Greek austerity plan is only a temporary pause on sovereign debt risk, and there's concern that there could be problems in Portugal, Spain, Ireland," said Michael Malpede, market analyst, Easy Forex, Chicago.
"We'll continue to see very choppy trade action today, as there's no real incentive to go either way," Malpede said. "If anything, traders appear to have a preference to sell the euro on rallies."
