The global economy is huge and it is not easy to manage. It would be impossible to actively manage everything and anything happening in the market. Currency Manipulation makes managing the global economy much easier. In order to know how to manipulate the exchange rate, you need to know what the exchange rate actually is.Currency manipulation is the act of changing its value against other currencies instead of leaving it free to fluctuate based on market dynamics. This can be done by fixing the exchange rate or deliberately increasing or decreasing its value.This practice is usually frowned upon since it results to an artificial distortion in currency prices. In fact, it is considered an illegal practice based on US laws and international agreements.
