Germany never? haha Whose banks willingly funded the insane real estate building boom (with loans denominated in CHF and JPY) based on the "convergence trade" in Hungary, Poland, Bulgaria, Romania? Yes, Austrian and German banks.
Somebody is on the hook for this madness and it's not banks in Eastern Europe because these guys have no banking industry to speak of. At the end of the food chain, it's all smart ass bankers from the EUR zone (and Russia).
Just painting a hypothetical scenario here, which is unlikely but not impossible. Let's say a Ukraine default drives Hungary and Poland into a depression, causing billions of write downs for German banks, causing nationalizations leaving the German government with billions in debt. To top it off, the German car industry gets a 75bln EUR government bailout. Good bye AAA for the Deutsche Reich.
