an outright ban on FX mortgages should have been put in place in Poland
Basically that is the case now. Hindsight tells us foreign currency loans are a bad idea. Just as it tells us the Swiss couldn't sustain the Peg - almost nobody expected it at the time.
the foreign currency mortgage bubble was on a much higher scale than in Hungary or Rumania.
It's quite the opposite, Poland is the least affected.
For better informed people who just hoped to get rich from a buy to let flat or live in a posh one that needed a mortgage higher than they could really afford and who were aware of possible currency fluctuations, I have less sympathy - it was basically speculation.
I can't see the difference between being informed or not, someone trying to make a quick buck through speculation is entitled to and fully responsible. The law agrees, stupid people can take out loans and buy houses .. and make money on it.
