Its membership in the euro currency union hanging in the balance, Greece continues to receive billions of euros in emergency assistance from a so-called troika of lenders overseeing its bailout. But almost none of the money is going to the Greek government to pay for vital public services. Instead, it is flowing directly back into the troika’s pockets, the International Herald Tribune reported.

Greece's radical left party has upended the country's politics with an idea as simple as it is seductive: Athens can renege on the deals it made in exchange for a bailout, and still remain in the euro. Greece's future, and possibly that of Europe's monetary union, may depend on how many Greeks buy into the idea, The Wall Street Journal reported. The Coalition of the Radical Left, known as Syriza, is competing with Greece's conservative New Democracy to become the biggest party in Parliament in June 17 elections that could send further shock waves through Europe.

Greece handed 18 billion euros (14.39 billion pounds) to its four biggest banks on Monday, the finance ministry said, allowing the stricken lenders to regain access to European Central Bank funding. The long-awaited injection - via bonds from the European Financial Stability Facility rescue fund - will boost the nearly depleted capital base of National Bank, Alpha, Eurobank and Piraeus Bank.

European officials are stepping up contingency planning for a possible Greek exit from the euro zone, even as Europe's leaders struggled to overcome differences on how to resolve the currency bloc's crisis at a summit meeting, The Wall Street Journal reported. Emerging from Wednesday night's informal European Union summit, Italian Prime Minister Mario Monti said most leaders had backed issuing common debt, or euro-zone bonds, to help support troubled members. But Germany and others opposed them and demanded Greece do more.

Worries that Greece might default on its debts or even leave Europe’s currency union have deepened since May 6, when Greeks voted in shocking numbers for a left-wing party willing to tear up Greece’s $170 billion international bailout agreement, the International Herald Tribune reported. These days, even though 80 percent of Greeks say they want to stay with the euro, talk of “drachmageddon” can be heard in conversations all around Athens — in executive suites, at mom-and-pop shops and even in nightclubs.

There has been no official announcement. No terms or conditions have been disclosed. But Greece’s banking system is being propped up by an estimated €100bn or so of emergency liquidity provided by the country’s central bank – approved secretly by the European Central Bank in Frankfurt. If Greece were to leave the eurozone, the immediate cause might be an ECB decision to pull the plug. Extensive use of “emergency liquidity assistance” (ELA) to help banks in the weakest economies has been one of the less-noticed features of the eurozone crisis.

As Greece girds for elections next month that could lead to its exit from the euro zone, economists are acknowledging an unsettling reality: No one knows what the bill will be, The Wall Street Journal reported. A wide range of potential price tags has been reported, anywhere from €150 billion to €1 trillion euros ($1.27 trillion). But none of these are comprehensive, nor are they meant to be—they don't, for instance, weigh the cost of an exit against the cost of avoiding one.

A Greek exit from the euro zone could expose the European Central Bank and the currency bloc it seeks to protect to hundreds of billions of euros in losses, landing Germany and its partners with a crippling bill, Reuters reported in an analysis. A Greek departure would take Europe into uncharted legal waters. The size of the burden other euro zone states could bear gives them a powerful incentive to keep Greece in the currency club.

The European Central Bank has reacted to uncertainty over Greece’s future in the euro zone by excluding four of the country’s banks from its regular liquidity-providing operations, The Globe and Mail reported. The move raises the pressure on Greece to stick to its international bailout by highlighting the risk that euro zone central bankers could pull the plug on its financial system. It reflected ECB fears that a planned recapitalization of Greece’s banks could be delayed.

Greece's future in Europe's common currency was in doubt after a last-ditch effort to form a new government failed and the country's political turmoil sparked a dramatic increase in bank withdrawals, The Wall Street Journal reported. After a week of fruitless negotiations, Greece's political parties couldn't agree on a governing coalition, leaving the country in political limbo until new elections next month. The delay could deprive Athens of badly needed international aid and deepen Greece's economic depression.
