Looking on the household debt according to the OECD data, the heaviest burden has been carried by citizens of Denmark, followed by the Netherlands, Ireland, Norway, Switzerland, Sweden, and Britain. Greeks have been slightly less indebted that Germans. Wow. This puts the discussion about debt into a different perspective.
Note that NPISH means 'Non-profit Institutions Serving Households', usually a tiny figure compared to the real household debt, of which a vast majority is mortgages.
Denmark also had a banking crisis of its own making in the recent years. It has wiped out more than 60 smaller banks, but was completely paid for by Danes themselves. No need for international assistance, no 'Troika', no publicity. Quite a boring financial crisis from the outsider's point of view.
A bubble usually entails a bust. Even in the cosy and well-managed state of Denmark.
