Currency intervention

Currency intervention is when a government or bank tries to change the value of its currency in the global market. To do this, they buy and sell their currency to other countries or banks. When they buy a lot of their currency, it makes it more valuable, and when they sell a lot of their currency, it makes it less valuable. By manipulating how much of their currency is available, they can make it more or less attractive to foreign investors.
