“Dirty” float, also called managed float, is the result of intervention by a nation's government or central bank in the behavior of its currency on the foreign exchange market. Not a fixed exchange rate, in which the value of a currency is pegged in a static relationship to some other value (like gold or a specific foreign currency), dirty float refers to an otherwise floating exchange rate governed principally by market forces but occasionally guided—the waters dirtied—by corrective intervention.
