The article studied changes of the rates of selected indexes of world stock exchanges and currencies exchange rates, Bitcoin, Special Drawing Rights and USD Value from 1.01.1998 to 30.03.2018. Autocorrelation and cross-correlation functions have been calculated for daily increments (up to 6 days) and monthly (up to 12 months). It was found that the statistical parameters of the series increments were considered as acceptable. There has been no significant correlation of the delayed price increments, which may be the result of a widespread lack of acceptance of Bitcoin.
