It seems that it would take a bit longer for Europe to make Euro sustainable in the long run. There is relief seen among many after the European Central Bank claimed that it might act as buyer of last resort for the bonds of troubled euro zone members, though under some conditions; there is a lot to be done to shed all fears.

With this move, all countries that have the same currency have reached the limit where they expect institutions to be developed, which ideally should have been after Euro was launched in 1999. "There's lots of progress that you couldn't have imagined politically two years. Things are moving fast", said Diego Valiante, a researcher with the Centre for European Policy Studies, a think-tank in Brussels.

It would take some time for things to be finalized before a sigh of relief can be actually taken. Even if a recent survey of chief financial officers by BDO, an auditing and business services firm, is to be referred, there is hell lot of uncertainty involved in as far as investing in southern Europe is concerned.

There is a lot being said on such matters, but converting it into action is what is taking a lot and shows how much the system has become weak.
