The main purpose of the research was to indicate what macroeconomic data is important for the short-term USD/PLN exchange rate volatility. The following research questions have been posed does the USD/PLN exchange rate react to the published macroeconomic data from the American economy and second could greater USD/PLN exchange rate volatility be observed during the COVID pandemic and has the war in Ukraine impacted the USD/PLN exchange rate volatility. International Foreign Exchange Market is the largest and most dynamically developing financial market in the world.

Data based on which the research was made is as follows: Consumer Price Index, Non-Farm Payrolls (NFP), Services PMI, Manufacturing PMI, Empire State Manufacturing Index or Retail Sales. The analysis of connections between the publication of macroeconomic data and the reaction of exchange rates was carried out using the linear regression model with GARCH process for the random parameter. Conclusions of this research is exchange rate volatility USD/PLN was higher after publications of the macroeconomic data from Americans economy. The strongest exchange rate reaction was after publication of data regarding inflation, Manufacturing PMI and Retail Sales. In the COVID (1.03.20—14.02.22) period we observed increased USD/PLN exchange rate volatility. Exchange rate volatility was expressly larger in the period of war in Ukraine (15.02.22 – end of experiment).
