As Eurozone finance ministers on Tuesday prepare to gather for a meeting to discuss Greece's bailout, some officials are once again holding out on approving much needed funds to help the financially-troubled country pay off its debts. Regardless of their reasons, the idea of limiting aid to Greece is different today from previous years and shouldn't even be an issue, given how increasingly vulnerable Europe's economy has become.

The architecture of Greece's series of bailouts in 2009, 2012 and 2015 was conceived by the 'Troika,' which includes the European Union Commission in Brussels, the International Monetary Fund in Washington and the European Central Bank in Frankfurt.

The marriage of these vastly different organizations that created the EU-IMF bailout was only ever a civil ceremony-- not a match made in heaven. Back in 2012, French President Nicholas Sarkozy railed privately against German Chancellor Angela Merkel's plan to bring the IMF on board to bailout Greece.

Needless to say, this dysfunction has not improved. Earlier this month, a leaked letter from IMF Managing Director Christine Lagarde warned Greece's creditors to restructure Athens' loans, or the Fund would no longer participate in any future rescue package. Another internal IMF discussion hinted at provoking a crisis to force the EU's hand and compel Eurozone leaders to undertake yet another significant restructuring of Greek debt. Lagarde and the IMF clearly view Athens' debt position as unsustainable, with sporadic threats of default interspersed with regular bailouts by the EU and IMF. For the Fund, this merely reinforces the widespread perception of financial instability in Europe, while contagion always threatens to spill over into global markets.

The notion of the IMF's non-participation in the bailout program, especially today, remains an empty threat. Lagarde and German Chancellor Angela Merkel know full well the panic that would ensue on global markets, already rattled by the prospect of a Brexit, anaemic global growth and weak US jobs figures, if the Fund were to withdraw entirely.

This comes as Greece tries to meet a June 7 deadline to repay 299 million euros to the IMF, a relatively small sum. But from this point onwards, the trickle turns into a tsunami, with over 18 billion euros in repayments due in 2016. In June and July alone, over 11 billion euros falls due. In order to access funds secured in the EU's third bailout package from last July, Athens needs to deliver more structural reforms.
