"This seriously compromises Belka's capability to hold office as the head of the central bank but if he does decide to stick around (which does seem like his stance at this point) – it will definitely be a long and complicated path to get him out of office, especially as these matters lay firmly in PM Tusk's hands in Poland and he is unlikely to officially call for the governor's resignation," Ishitaa Sharma, Citi foreign exchange strategist, wrote in a research note.
The zloty moved lower in trading Monday, ahead of an expected press conference by the Prime Minister on Monday afternoon.
In his four years in office, Belka has become one of the most important figures behind Poland's emergence as one of the most successful economies in the former Soviet bloc, and the sixth largest economy in Europe. Economic growth in the country is expected to accelerate to 3.3 percent this year. However, the country is also at risk of deflation, with inflation in May just 0.2 percent higher than May 2013. The central bank's target is 1.5-3.5 percent.
