John Kay had an article in the Financial Times earlier in the week, and this seems to have caused quite a ripple around the blogsphere (Eurozone Watch, Economonitor, Claus Vistesen at Alpha Sources). The article was about whether or not it was technically possible for Italy to leave the Eurozone. (Update: Sebastian has a fresh post over at Eurozone Watch Blog continuing the discussion).
John Kay’s conclusion, and it is supported by a very reasoned commentary by Sebastien Dullien at Eurozone Watch Blog (welcome Sebastain and Daniela), is that there is no in-principle technical difficulty in exit. The most authoritative piece of work on this topic that I know of comes from Harvard International financial law specialist Hal Scott. The paper was written back in 1998, and was provocatively entitled “When the Euro Falls Apart“. Despite the title the paper is a tightly reasoned piece of work whose main conclusion is that not only is euro-exit technically perfectly feasibe, in fact the mechanisms which would make this possible were incorporated from the start (in particular keeping independent central banks with their own reserves). I think those who were able to think clearly back then – and were able to use some emotional intelligence – were always aware that there were question marks over Italy’s ability to go the distance.
So the problem is not a technical one. But as John Kay indicates it *is* a political one:
