If Jan Krzysztof Bielecki radiates satisfaction as he sits at his conference table, decorated with a bust of Adam Smith, it is because the head of Poland’s largest bank has been proved right.

His bank only offered Polish zloty loans, which left it handicapped in the fast-growing, lucrative mortgage market during Poland’s recent real estate boom.
