It is therefore premature to draw strong conclusions, but a few observations may be useful. First, a small point of measurement. In most modern economies, the share of GDP accounted for by services generally has long been growing as agriculture and manufacturing get (relatively) smaller. It would not be surprising for the finance sector to be part of that.
The European leaders agreed that the fiscal rules have to be tightened since their application in practice had proven to be too weak. They agreed, secondly, that macroeconomic imbalances should be addressed earlier and more effectively. The crisis demonstrated that sound public finances are a necessary, but not sufficient condition for financial and economic stability.
