ECB's Asmussen says Greece to need aid beyond 2014

The government in Athens probably won't be able to return to finance its debt on financial markets in 2015 and 2016, thus requiring another assistance program, Joerg Asmussen told German public broadcaster ZDF.

Many of Greece's partners in the 17-nation eurozone loathe granting Greece yet more funds and more long-term assistance, not least Germany's Chancellor Angela Merkel who is heading into an election year.

International creditors have kept debt-ridden Greece afloat since 2010 and have pledged rescue loans worth €240 billion ($306 billion) through 2014 because the country could no longer refinance its debt on markets. Investors demanded prohibitive interest rates from Greece as they feared the country might default on its debt.

But a much deeper than expected recession and delays in implementing austerity measures and reforms have created a new budget shortfall of some €30 billion under the current bailout program.

The finance ministers of Greece's eurozone partners, the European Central Bank and the International Monetary Fund will meet on Tuesday to decide how to plug that hole.

"Next week we should settle the financing for the years 2013 and 2014, but you have to be honest and say that we don't really expect the country to have access to markets in 2015 and 2016. That means a follow-up program would be necessary," Asmussen told ZDF.

The creditors initially hoped Greece's debt burden could be reduced to a more sustainable level of 120 percent of its gross domestic product by 2020. But Greece's debt is now forecast to hit 190 percent of GDP next year, leading creditors to propose granting the country two more years to meet the target.

Greece is heading into a sixth consecutive year of recession, which will further deteriorate its debt position measured relative to its economic output. The jobless rate hovers around 25 percent, and youth unemployment has hit 50 percent.
