Euro Group open door to an October long ordeal of market uncertainty!

The linked report from Deutsche Welle, on the outcome of yesterday's Euro Group, Ecofin meeting appears to condemn the markets to extreme instability, most probably concentrated on Europe's banks and the sovereign debt of Italy, Spain and France, throughout the remainder of October, historically always a difficult time for financial markets. The report opens with the following flat statement:

Greece will have to wait until the end of October for a decision from eurozone partners on whether they will release the next installment of its international bailout fund.

One major item was apparently agreed and supposedly resolved, that being Finland's demand for collateral on future monies sent to Greece:

The finance ministers' meeting in Luxembourg did see one success in the resolution of an ongoing debate. Eurozone ministers struck a deal on Finland's demand for collateral in exchange for participating in a second bailout for Greece.

All states sharing the euro currency will be allowed to request collateral in exchange for accepting worse interest rates on their credit to Greece.

This blog predicts, that the supposed NO stated by other small nation's will be called into question when the exact details of the reduction in interest rate accepted by the Finns becomes clear (collateralised loans normally pay a smaller return to reflect the lender's reduction of risk) and the quality of the collateral  being provided.

When the Euro Group eventually decide that Greece cannot possibly get any more cash, the only possible end result, what level will the world's markets then be at I wonder?
