In one respect, the EU agreement was anything but subtle. The fact that the Eurozone countries and those aspiring to join them were prepared to go ahead without the UK (and a few others) suggests that they have something serious in mind. But what – the announcement is pretty much a restatement of the Growth and Stability pact, and under present circumstances, the deficit targets can only be seen as aspirational.
Applying one of the approaches that used to be standard in Kremlinology (not necessarily a reliable one, then or now) I’m going to assume that the EU leaders are acting with some sort of coherent goal in mind and work from there. In particular, I’m going to assume that everyone who matters now recognizes the need for a big monetary expansion and the use of newly created money to resolve, or at least stabilize, the debt crisis.
There are a bunch of obstacles to this:
(i) The desire of the ECB to save face, to avoid admitting its large share of responsibility for the crisis and, if it can, to hold on to its central position and to the inflation targeting system
(ii) The belief of the German public (and some others) that they are being made to bail out a bunch of feckless Southerners, rather than (the reality) saving French and German banks from the consequences of their bad decisions, and preserving the European economy on which the Germans depend as much as anyone else from the disastrous regulatory failures of the Euro-elite, including the ECB, European Commission, financial regulators and so on
(iii) the problems with EU treaty amendments requiring unanimous consent
