The European common currency advanced slightly against the dollar on hopes Greece will receive a second bailout that would make the debt-mired nation avoid default, as euro zone officials said on Thursday Greece's bailout will be ready for approval on Monday.

Greek Finance Minister Evangelos Venizelos said Greece had fulfilled the two demands of the EU and IMF to secure the second bailout. He said the Cabinet outlined how to fill a 325 million euro gap of budget cuts for the current year, while both leaders of Greece's biggest political parties signed written commitment to adopt austerity measures on Wednesday.

Also, three euro zone officials said the ECB is swapping Greek bonds with new ones in order not to bare losses in a debt restructuring condition.

However, investor's vibes are mixed as some are optimistic that Greece will receive the second aid package after fulfilling all requirements asked by euro area finance ministers, while others are still worried that there may be other impediments that would prevent delivering the aid to the debt-mired Greece.

There are worries that Greece may break its vows like what happened several times since the eruption of the debt crisis more than two years ago and especially that a debt restructuring deal has to be also approved in line with the aid package.
