* Euro hurt by reports Greece wants safety net renegotiated
* US stocks little changed on Greece, interest rate outlook
* Treasuries prices rise as higher yields draw investors

NEW YORK, April 6 (Reuters) - The euro fell broadly on Tuesday and U.S. stocks were little changed, pressured by rekindled fears about Greece's finances and prospects of higher interest rates in the United States.
European shares hit an 18-month closing high, reacting to recent U.S. strong economic data in the first trading day since Thursday after the long Easter holiday weekend.
Commodity-related shares rose on higher prices of raw materials.
Jitters about Greece resurfaced following 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 report, 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 [

"This shows the debt crisis has intensified there, and I think there is frustration that there is not more of an agreement about how to deal with Greece and concern that the solution is dragging out."
On Wall Street, bank shares rose on positive comments from brokers, helping to offset worries about the impact of rising Treasury yields. Mortgage rates are pegged to yields of the benchmark 10-year Treasury note.
"Holding stocks back is a big surge in the 10-year yield, and people may be expressing some concern on how the impact may be on the housing market," said Peter Jankovskis, co-chief investment officer at OakBrook Investments LLC in Lisle, Illinois.
"We have seen some good signs of progress in terms of economic recovery and growth, but now we're starting to see some potential roadblocks coming into play."

EURO SINKS
The worries about Greece caused a sell-off in the euro <EUR=>. The single European currency was down 0.88 percent against the dollar at $1.3364, after hitting a session low of $1.3357, the lowest in more than a week.

Benefiting from rising oil prices, the Canadian dollar <CAD=D4> broke parity with the U.S. dollar for the first time since July 2008, rising to C$0.9999 per U.S. dollar.
U.S. Treasury prices rose as a recent sharp rise in yields attracted buyers. The benchmark 10-year U.S. Treasury note <US10YT=RR> was up 7/32 in price, with the yield at 3.9584 percent, easing from 3.99 percent late on Monday.
