Marek Belk, head of Poland's central bank, says Poland should prepare for impact of a general slowdown in the eurozone. Poland's economy is expected to grow at 4% for 2011, but experience a slower rate of growth in 2012. Poland's public debt is at 55% of GDP compared to 120% for Italy. Belka said the mistakes in Italy show it is important to stay ahead of the markets. The action taken in Italy on November 14, 2011, if taken 2 months earlier would have prevented the jump in Italy's borrowing costs. Risks facing Poland come from the fact that a large proportion of the nation's banking assets are owned by banks of other European countries- as much as 70% of Poland's banking assets. As a result if these banks experience difficulties the local branches could become orphans. Belka would like to see private capital in Poland be used to bring a larger share of the banking sector back in Polish hands. Belgian and Portuguese banks are considering selling their banking operations to Polish banks, and PKO Bank Polski SA, PZU SA are possible buyers.
