Kleptocracy (or sometimes Cleptocracy) (root: Klepto+cracy) is a form of government. It means literally "rule by thieves". It is the end-point of political corruption, where no pretence of honesty remains, and the government of a country exists solely to enrich its rulers and to perpetuate their rule.
Kleptocrats often use money laundering and anonymous banking as a way of protecting and concealing their wealth.
