Investors are likely to focus on Greece as a series of meetings will be held this week with its government and other European leaders, who are expected to discuss in detail the austerity measures to be introduced in the country.

Last week Greece raised 4 billion euros ($5 billion) in a sale of three-month treasury bills that would help it pay principal bond payments of 3.2 billion euros to the ECB on Aug. 20. Domestic banks bought enough treasury bills to ensure that the government could repay the ECB without trouble.

However, Greece is not fully out of its problems yet, as the government needs to identify a further 4 billion euros of spending cuts that will be delivered over the next two years. This is part of the 11.5 billion euros of savings demanded by the Troika, consisting of the European Union, European Central Bank and International Monetary Fund, in return for more loans.

“Unfortunately, there are no easy options left and some or all of the coalition parties may have to go back on promises that they made to the electorate in order to meet the shortfall,” Ben May, an economist at Capital Economist, said.
