The seemingly never-ending Greek debt crisis returned to the fore this week, with the country trying to secure a fresh tranche of bailout money to keep it financially afloat over the summer.

The Greek parliament over the weekend approved an unpopular package of pension reforms and tax hikes that is seen as taking it one step closer to wrap up the long-delayed first review of its €86 billion bailout program agreed last summer. Concluding the review is key to unlocking bailout funds, which are crucial to repay €2.3 billion ($2.6 billion) to the European Central Bank in July. Greece is also due to pay the International Monetary Fund €300 million in June.

The Eurogroup of eurozone finance ministers met on Monday to discuss Greece’s newest austerity package, and while the group welcomed the overhauls, no formal approved was granted.

The biggest problem for Prime Minister Alexis Tsipras is that key creditors aren’t content with Sunday’s measures alone. The Eurogroup is demanding more work on additionally “contingency measures” in case the bailout goes off course. Greece and the European Commission have previously opposed such demands, according to media reports.

Violence erupts as Greece passes austerity laws

Furthermore, the IMF believes that Europe is trying to make Greece reach an unrealistically high budget surplus. If Europe won’t reduce the target, IMF head Christine Lagarde said in a letter to eurozone finance ministers sent on Thursday, Greece would need to introduce austerity measures worth a further 2% of GDP.

In what is seen as a historic step in the Greek debt crisis, the eurozone finance ministers at Monday’s meeting actually talked about debt relief for the country.

Political observers are hopeful now a deal will be reached before the July debt repayment, but the stalemate is already pointing to another Greek drama this summer.

Here are the key days to watch in Greece’s debt debacle.

May 24th, Eurogroup meeting

Between now and May 24, Greece and its creditors are likely to race to reach a deal that will satisfy all sides. The May 24 meeting in Brussels, is when analysts are hopeful the bailout review will successfully wrap up and clear the roadblock for the next cash injection.

If no agreement is sealed at the late May summit, it could spell trouble for Greece and the eurozone, said Cathal Kennedy, European economist at RBC Capital Markets.

“It’s in both sides’ interests to get [a deal] as far in advance as possible [of the debt repayment] to avoid a rerun of what we saw last year, where the uncertainty and damage to the Greek economy probably had some spillover to the wider euroarea,” he said.

July 20th, ECB repayment

Crunch time.

Greece is due to pay €2.3 billion to the ECB and will struggle to find the money for it without the bailout cash. Last year, the government defaulted on an IMF loan, seriously raising concerns the country would exit the eurozone.

“The ECB is the hard deadline this year, once we start to get into 2017 we’ll get some more again, but this year it’s the ECB repayment,” Kennedy said.
