Greece held a new successful auction of six-month treasury bills on Tuesday, raising 812.5 million euros (1.07 billion U.S. dollars) at a marginal smaller interest rate compared to January's similar sale, Greek Public Debt Management Agency officials announced.

The debt-laden country secured an interest rate of 4.86 percent from 4.9 percent in the previous auction on January 10 that raised some 1.625 billion euros (2.15 billion U.S. dollars). The interest rate for 26-week treasury bills stood at 4.95 percent during December's sale.

Greece pushed forward by one week Tuesday's auction, as state funds run out and international lenders press the government to step up structural reforms and introduce further spending cuts in exchange of a new aid package this winter in time to avert a Greek bankruptcy.

Athens must repay a 14.5 billion euro (19.18 billion U.S. dollars) bond on March 20 and beyond the tranches of rescue loans by EU partners and International Monetary Fund since 2010, relies on monthly treasury bills auctions.
