The International Monetary Fund (IMF)'s director for Europe refused to rule out Greece needing a further bailout in the future — despite the success of its bond issue earlier during the week.

"Obviously Greece has large financial obligations in the next couple of years," Reza Moghadam told CNBC from the Spring meeting of the IMF and the World Bank in Washington D.C.
"Thanks to the extension of maturities by the European partners… those obligations come in gradually and they are a long time ahead… but it is clear that Greece will continue to need to raise money either from the markets or from the official sector to continue to meet those obligations."
Reuters reported on Friday that Moghadam had told a news conference in Washington that Greece was likely to need further financial help.
"The financing needs for the next two years remain very large. There will be continued need for support," he said, according to the news wire.
Greece tapped the bond market with its first long-term issue since 2010 on Thursday. It sold 3 billion euros ($4.2 billion) of five-year debt, at a lower-than-expected yield of 4.95 percent.
The deal was more than six-times oversubscribed, attracting orders of around 20 billion euros.
