Definition

Exchange Rate Dirty Float, also known as a managed float, refers to a system of exchange rate management where the value of a currency is largely determined by market forces, such as supply and demand, but is occasionally influenced by a country’s central bank or monetary authority to stabilize or guide the currency’s value. This type of intervention can be carried out through various means, including buying or selling currencies in the foreign exchange market or adjusting interest rates.

Examples

  1. China: The Chinese Yuan operates under a dirty float system where the People’s Bank of China occasionally intervenes to manage its value within a certain range.
  2. India: The Reserve Bank of India periodically engages in currency intervention practices to ensure that the Indian Rupee remains stable.
  3. Brazil: The Brazilian Central Bank often steps in to manage the Real’s value against major currencies to prevent excessive volatility.
