NEW YORK, April 6 (Reuters) - The euro fell broadly on Tuesday as worries about Greece's finances resurfaced, and two major U.S. stock indexes rose as minutes from the U.S. Federal Reserve's latest meeting eased concerns over rising interest rates.
The jitters about Greece spurred safe-haven demand for U.S. Treasuries and also drove gold to a one-month high as investors sought safety.
Crude oil hit an 18-month high as prices inched toward $87 a barrel on continued optimism over the economic recovery.
Concerns that the Greek financial crisis is far from over increased on reports that Athens wants to amend a deal struck at a European Union summit last month to bypass a contribution from the International Monetary Fund, which could impose tougher conditions in exchange for aid.
A Greek Finance Ministry source denied the reports, but yields on the country's 10-year bonds <GR10YT=TWEB> rose above 7 percent for the first time since the end of January, according to Tradeweb. For details, see [

Wall Street initially dropped on the Greek woes and also on speculation that U.S. policy makers could raise interest rates earlier than expected after a batch of positive economic data in recent days.
Those fears faded in the afternoon after the release of minutes from the Fed's last policy meeting signaled that the U.S. central bank could maintain ultra-low interest rates for even longer than investors have anticipated if the economic outlook worsens or inflation drops. [
]"I think the interpretation is rates are going to stay low and that's giving the impetus to the market to move higher," said Kurt Brunner, portfolio manager at Swarthmore Group in Philadelphia.
"Couple that with what appears to be continued healing ... and it seems that at least right now, it's the best of all worlds," he added.
The benchmark S&P 500 and the Nasdaq both closed higher, though the Dow industrials finished slightly lower.
The Dow Jones industrial average <

European shares hit an 18-month closing high, on the first trading day after Friday's release of strong U.S. economic data, even as gains were capped by doubts on Greece's ability to emerge from its fiscal crisis. European markets were closed on Friday and Monday for the Easter holiday.
