In a dual exchange market, one exchange rate is free and controlled by the market forces while the other exchange rate is controlled by the government through foreign exchange intervention or foreign exchange control. The definition of dual currency market is that there are two exchange rates, one of which is the free rate, which is not controlled by a bank or other financial institution, and the other is controlled by the government or central bank. The purpose of foreign exchange intervention or foreign exchange control is to ensure stability in the foreign exchange market and to ensure that this free rate is demanded on the foreign exchange market. Moreover, to protect foreign investment and maintain our foreign trade balance, we must protect ourselves from the forces of supply. Foreign exchange markets are necessary because we have to acquire local currency before we can trade with another country.

The dual currency market is a type of financial market in which two or more currencies are traded. This type of market is typically found in developing countries that have an unstable national currency, but it can also exist in countries with stable national currencies. The existence of the dual currency market creates a divergence between trading rates for different currencies, leads to increased volatility, and affects the exchange rate between the two currencies.

The dual currency market is a type of economic system where businesses and individuals are allowed to buy goods and services with the use of more than one type of currency.

It is a market where there are two or more currencies being traded. It helps to have this kind of market, and many countries where there is a rather unstable national currency prefer this kind of system.
