Depending on the type and depth of such shocks, they become politically generated shocks and, in particular, affect the monetary sphere. The article investigates three types of politically generated shocks and their impact on the monetary sphere. It has been found out that the shocks generated by political populism are characterized by fiscal domination in the economy, the use of monetary measures in the budget deficit financing. Shocks arising after the use of international sanctions against certain countries have an external origin and primarily cause the increase in national exchange markets volatility. On the whole, macroeconomic and, especially, monetary instability is the result of the great shocks for the economy, the depth and duration of which are determined by the nature of the crisis, particularly, when country participates in the military conflict. The aforementioned types of politically generated shocks are analyzed based on the experience of countries such as Argentina, Turkey, and Ukraine, which at one time introduced the regime of inflation targeting in monetary policy, but were forced to modify it influenced by political and economic instability.

The main purpose of the empirical analysis is to determine the current trend of the USD/UAH exchange rate (is it random or permanent), indicate the presence of seasonality in foreign exchange rate dynamics and evaluate its sensitivity to external shocks. Three hypotheses are tested using several methods of time series analysis (autocorrelation analysis, ADF, Phillips-Perron and Granger tests), including a trend-season model using a time series of one variable (ARMA), a multifactor VAR-model, impulse functions. The results show that, the movement of the hryvnia exchange rate against the US dollar is a stochastic process. Its trend has a random component and tends to change sharply over time. Moreover, exchange rate fluctuations are seasonal. It depreciates in the first and second quarters, and strengthens in the third and fourth. Some macroeconomic indicators cause a positive or negative reaction of the USD/UAH exchange rate. This indicates that today the Ukrainian foreign exchange market is relatively efficient, but stable, since its reaction to external shocks is short-term, insignificant and tends to fade out. Although the findings are controversial, they support the generally accepted view that the exchange rate formation is a multifactorial process that depends on several macroeconomic factors. However, high volatility and random walk specification indicate that it is almost impossible to predict its future value at this time.
