Results of fractal analysis of currency exchange rate fluctuations in several groups of countries with different financial and economical systems during the period 1995-2000 are presented. We demonstrate that the C. K. Peng’s detrended fluctuation analysis can be used as a sensitive tool for identifying inflation trends and revealing unstable regimes in currency dynamics over broad range of temporal scales. The developed quantitative criteria allow to characterize the efficiency of the governmental monetary control under the conditions of economic crises and crashes of international and domestic monetary systems.
