Final answer:
Currency kept at an artificially high exchange rate is controlled by the central bank and is part of the monetary base, which includes currency in circulation and bank reserves. Central banks may intervene in the exchange rate market, purchasing foreign currencies to maintain their currency's value, though this has an opportunity cost. Various strategies can be employed by governments to manipulate their currency's value, with potential consequences like inflation.
Step-by-step explanation:
The currency mentioned is one that is kept at a high artificial exchange rate and is overvalued. This type of currency is controlled by the national central bank. Such currencies are often part of the monetary base which includes both the currency in circulation and bank reserves held in vaults. However, only the portion that is in circulation is counted in the money supply.
Central banks may intervene in the exchange rate market to maintain the value of their currency. They may create and sell their own currency in order to purchase foreign currencies such as U.S. dollars or euros, which are then held as reserves. While these reserves are necessary to maintain the pegged or controlled exchange rate, they come with an opportunity cost and central banks may be reluctant to increase such reserves indefinitely.
When a government seeks to manipulate the value of its currency, it can pursue various strategies such as changing interest rates, altering trade incentives, and directly intervening in exchange rate markets. Such interventions may serve short-term economic objectives, but they also risk causing imbalances like those experienced in countries with hyperinflation due to excessive money printing to finance budget deficits.
