As a consequence, there was a crisis in international confidence in Greece's ability to repay its sovereign debt, as reflected by the rise of the country's borrowing rates (although their slow rise – the 10-year government bond yield only exceeded 7% in April 2010 – coinciding with a large number of negative articles, has led to arguments about the role of international news media in the evolution of the crisis). In order to avert a default (as high borrowing rates effectively prohibited access to the markets), in May 2010 the other Eurozone countries, and the IMF, agreed to a "rescue package" which involved giving Greece an immediate €45 billion in bail-out loans, with more funds to follow, totaling €110 billion. In order to secure the funding, Greece was required to adopt harsh austerity measures to bring its deficit under control. Their implementation will be monitored and evaluated by the European Commission, the European Central Bank and the IMF.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did the international banks have doubts about Greece's ability to repay?
sovereign debt
