Adjustment of fiscal policy to the conditions of the national economy performance in the EU, and in the monetary union in not too distant future, requires the creation of a certain margin of freedom resulting from the shape of public finance. Such a margin means that fiscal deficit is considerably below 3% of GDP. In view of the difficulties the Polish public finance was exposed to in recent years, especially in the period of Poland's accession to the EU and considering many macroeconomic risks involved, it would not be the best move to artificially (i.e. at any price) accelerate Poland's entry to ERM2 and to the monetary union.
