Stock indices closed higher on hopes for a deal between Athens and its creditors. The next round of the debt talks has started today in Luxembourg. Greek Finance Minister Yanis Varoufakis said that Athens will not provide a new reform proposal. It is unlikely that a deal will be reached today.

The Bank of Greece said in its annual report on Wednesday that failure to reach a deal with creditors could lead to the exit from the Eurozone and to crisis in Greece.

International Monetary Fund (IMF) Managing Director Christine Lagarde said that Greece will not get extra time to repay its IMF loans.
