Everything you need to know about the September 12 German court decision that could rock the entire world

The eurozone is running out of bailout cash, and the German Constitutional Court now holds the fate of Europe in its hands.

The European Financial Stability Facility, the original euro area bailout fund established in the summer of 2010, is down to about €248 billion of lending capacity left after existing bailouts for Greece, Portugal, and Ireland are accounted for.

Spain and Italy – the next two countries expected to be in line for a bailout – could have combined financing needs as large as €703bn over the next two years, according to Citi estimates, dwarfing the existing capacity of the EFSF.

Those huge numbers underscore the need for the additional firepower of the European Stability Mechanism, the new bailout fund expected to replace the EFSF and make available hundreds of billions of euros in additional lending capacity to struggling member states.

However, the ESM has still yet to be ratified, which has many counting chickens before the eggs have hatched, so to speak.

The 16 judges that sit on the Federal Constitutional Court of Germany need to sign off on the fund's constitutionality in order to make the fund operational – and the Court is widely expected to do just that when they deliver a ruling on ESM ratification on September 12. (more)
