CRISISBOOM

Prime Minister George Papandreou has struggled to garner support for a new package of $39.5 billion in spending cuts and tax hikes demanded by the European Union and the International Monetary Fund, which last year granted his debt-ridden nation $155 billion in bailout loans.

But the measures have sparked riots on the streets of Athens and open criticism from his own Socialist lawmakers. Papandreou’s desperate efforts to form a coalition government with the opposition conservatives collapsed Wednesday, and the political crisis deepened yesterday when two of Papandreou’s lawmakers resigned. A planned Cabinet reshuffle was delayed until today, after Papandreou chaired a seven-hour emergency meeting with Socialist lawmakers to try and ease the crisis.

The party feud heightened worldwide concern that a Greek financial collapse could trigger panic elsewhere in the 17-nation eurozone — a fear that saw borrowing costs in vulnerable EU countries surge and stock markets come under pressure.

“We will prevail and we will hold on. We have as a country in the past successfully faced major crises. As hard at this struggle is, we cannot run away from our fight,’’ Papandreou told party lawmakers. “We will fight and we will win.’’

Fearing further chaos, the EU’s top financial official, Olli Rehn, indicated in Brussels that Greece will likely get its next financial lifeline next month, despite the EU finance ministers’ failure to agree on a new bailout package for the country.

Rich EU countries like Germany and the Netherlands want private creditors to share a big part of the burden of helping Greece, while the European Central Bank fears those demands could trigger a partial default that would spark panic on financial markets and pummel banks in Greece and across Europe.

Rehn, the EU’s monetary affairs commissioner, said eurozone ministers would likely agree Sunday to give Greece the next $17 billion loan from last year’s $156.2 billion package. However, the aid will only be paid if Papandreou’s government, which faces a vote of confidence within days, can get new budget cuts and privatizations through Parliament before the end of the month.

The loan would keep Greece afloat until September and give finance ministers and the ECB until their next get-together in July to resolve their differences, Rehn said.

His comments raised hopes that Greece would avoid a quick default, alleviating the selling pressure on the euro, which had earlier fallen below $1.41 for the first time in three weeks.

But fears of a second Greek bailout drove the yield on Greece’s two-year bonds above 30 percent for the first time ever yesterday and kept the 10-year equivalent near all-time highs around 18 percent.

Even if a second bailout is granted to Greece, many analysts think the road will still end in default, and some even wonder if Greece will stay in the 17-nation eurozone.

“While an additional bailout package may stave off near-term disaster, a major debt restructuring seems inevitable at some point and Greece’s future in the currency union is looking ever more doubtful,’’ said Jonathan Loynes, chief international economist at Capital Economics.

Some economists fear that a Greek default would trigger financial chaos like the Sept. 2008 collapse of the US investment bank Lehman Brothers.

“The risk of a ‘Lehman moment’ for the eurozone is increasing,’’ said Neil MacKinnon, analyst at VTB Capital.
