NEW YORK, May 26 (Reuters) - The euro fell to a record low against the Swiss franc on Thursday on worries that Greece was again teetering on the brink of financial crisis, driving a bid for safe-haven U.S. government bonds.
Comments from Eurogroup President Jean-Claude Juncker rattled markets and raised doubts about whether the International Monetary Fund would release Greece's next round of financial assistance at the end of June. [ID:nLDE74P1HC]
After initially wobbling over the Greece worries, U.S. stocks squeezed out modest gains, but U.S. crude oil fell more than 1 percent on disappointing U.S. economic growth and jobs data.
Still, the euro zone sovereign debt fears stuck with investors.
"There has been a lot of back and forth between the EU and the ECB on IMF aid to Greece, and that does not help the euro at all," said Kathy Lien, director of currency research at GFT Forex in New York.
The latest U.S. economic data underscored the view that the country's recovery has hit a rough patch.
The U.S. economy grew at an annual 1.8 percent rate in the first three months of this year, the Commerce Department said, unchanged from an earlier estimate and weaker than most forecasts.
A separate report from the Labor Department showed the number of Americans claiming unemployment benefits unexpectedly rose last week by 10,000 to 424,000. For details, see [ID:nN26233734]
