Managed float regime is the current international financial environment in which exchange rates fluctuate from day to day, but central banks attempt to influence their countries' exchange rates by buying and selling currencies. It is also known as a dirty float.
In an increasingly integrated world economy, the currency rates impact any given country's economy through the trade balance. In this aspect, almost all currencies are managed since central banks or governments intervene to influence the value of their currencies. According to the International Monetary Fund, as of 2014, 82 countries and regions used a managed float, or 43% of all countries, constituting a plurality amongst exchange rate regime types.
