The correlations and the influence of the monetary policy pursued by the central banks of developed countries, primarily by the Federal Reserve System (the central bank of the United States), on the economies of developing countries is a subject of research, especially since the outbreak of the last financial crisis. Decisions concerning shifts in attitudes in the monetary policy taken by the monetary authorities of the largest economies, influence investors’ behaviour. Due to globalization and financialization, short-term capital flows occur very quickly and on a significant scale. Argentina is an illustration of the consequences of monetary policy tapering by the FRS for the economy of a developing country. Argentina was supported during the period of disturbances by the International Monetary Fund. Nevertheless, it seems that this solution is insufficient in view of the globalization of the effects of the monetary policy pursued by the economically strongest countries.
