When a genie escapes from a bottle it is hard to persuade it back in again. Doubts over the future of the euro will be equally hard to bring back into control.
Even if the sizeable measures taken over the weekend at the emergency session in Brussels have stemmed the immediate rout in the market and conditions improve, this is not yet proof that the eurozone will really get to grips with its fundamental problems.
And it will take some years for the eurozone to rebuild its reputation and re-establish confidence in its future.
Mismanagement is at the heart of the crisis.
