The stagnation in economic growth is a problem of developed market economies. Its cause may be a lack of demand caused by the phenomenon of deflation.

The evolution of the exchange rate CZK/EUR is being analysed on the one hand, and on the other the developments in the GDP, exports and imports, and their relationships, using the sensitivity rate, regression analysis and comparison of standardized values within 20 quarterly periods in 2010-2014. The results show that after CNB intervention, there has been a noticeable growth in GDP, while exports grew with a higher dynamics than imports
