Greece raised 1.137 billion euros ($1.280 billion) in an auction yesterday of six-month treasury bills at the same 2.97 percent interest rate it last sold them at last month, the Greek Public Debt Management Agency said. Since the last auction on Aug. 5, Athens and its international creditors agreed to a third huge international bailout for the debt-stricken country worth 86 billion euros over three years. However, there has not been a boost in investor confidence as early elections were called for Sept. 20 after Alexis Tsipras resigned as prime minister last month following a serious split within his radical-left Syriza party over the bailout. Yesterday's auction of 875 million euros of six-month treasury bills was over-subscribed by a ratio of 1.3. Athens sold 812.5 million euros of six-month bills last month. Greece has not had access to long-term capital markets since the start of its debt crisis in 2010 with the exception of two brief returns to medium-term markets.
