LONDON/NEW YORK, March 29 (Reuters) - Expectations that European Union efforts will ease Greece's sovereign debt crisis lifted the euro on Monday and cleared a path for gains in global equities.
The European Union, European Central Bank and International Monetary Fund last week moved to create a safety net for Greece, seeking to persuade markets that the country's bonds and those of other peripheral euro zone economies would not default.
The euro, which has been battered by the crisis, rose about a quarter percent against the dollar <EUR=> to $1.3446. It also gained against the Swiss franc, Swedish crown, Japanese yen and British pound.
"The EU agreement on Greece instilled some confidence, and we are seeing a degree of a relief rally although a modest one," said Lee Hardman, economist at Bank of Tokyo-Mitsubishi UFJ.
"Greek yields are still elevated, and Greece is not out of the woods yet by any stretch of the imagination."
Greece remained in focus with the sale of seven-year debt seen as a barometer of demand for the country's debt.
The Greek bond was set to raise 5 billion euros, a source at one of the banks charged with selling the debt said, but could price at around 6 percent, more than twice the yield that Germany pays on its debt. [

U.S. government debt prices declined slightly as improvements in the U.S. economy and brightening prospects for Greece lessened the appeal of Treasuries as a haven from risk. Benchmark 10-year Treasury yields rose 0.01 percentage point to 3.86 percent.
The removal of immediate worries about Greece allowed global stock markets to focus elsewhere.
