You're right about the coming inflation. It's quite scary in Warsaw
Poland has itself to blame, though I can appreciate the politics.
1) The main driver of inflation, across the board - regardless of industry - is energy prices. Nobody held a gun to Poland's head when it came to reducing purchases of Russian energy. Great virtue signaling, but you didn't have even a 1/10th of the resources the Germans had to address the issue.
2) One thing which could have significantly depressed prices for key food items in Poland, is if you opened your market to Ukrainian agri-produce. Of course, this would come at the price of the destruction of your own agriculture industry (something many countries did, perhaps not as rural in demographic profile as Poland).
3) Idiots have been appointed by PiS into the economic bloc of the cabinet, as well at the Central Bank. Main criteria seems to be loyalty to Chairman Kaczynski's unorthodox views on how markets work.
4) Being on the Zloty, in times like these, is of course a much more probable way of ending up with high inflation, than being on the Euro.
Setting price controls, as Jon wants, is rarely a good solution. Key word - rarely. Those rare cases where it sort of, maybe, potentially works - are almost all cases where prices are set higher than would otherwise exist in the market - not lower. This is normally done to benefit a thin cohort of farmers, at the expense of the rest of the population. Price controls in the other direction, are great at putting people out of business.
