The fact is Poland's banking system has no inherent weakness - at least compared to its Western counterparts. There is no toxic subprime debt on the balance sheets
Are you taking the piss? People took out 100% (or even 120% mortgages) in Swiss Francs and the Zloty has collapsed. A good friend of mine took a 110% mortgage back in June (i.e. 360,000zl for a 330,000zl flat) and currently has a 500,000zl mortgage 'secured' on a flat worth 280,000zl! How is that not toxic?
