Explanation of Double Exchange Rate System Terms

A dual exchange rate regime refers to the existence of two different official Exchange rate regimes in a country or region. In general, the official exchange rate of a country refers to the exchange rate published by the central bank, which is used to guide international currency transactions and the operation of the foreign exchange market. The dual Exchange rate regime means that there is another exchange rate system besides the official exchange rate. The exchange rate of this system is usually determined not by the central bank but by market supply and demand.

The dual Exchange rate regime usually occurs in some countries or regions with special economic systems, such as countries in the period of planned economic transition or countries with serious economic crises. Under these circumstances, the government may adopt a dual Exchange rate regime to control the operation of the foreign exchange market in order to deal with the instability of the market and control capital flows. In this way, the official exchange rate is used for normal international trade and capital flows, while another exchange rate system is used for specific economic activities or capital accounts.

Under a dual exchange rate system, the official exchange rate is often set at a lower level by the government or central bank to encourage exports and attract foreign investment. This official exchange rate is usually used for formal international trade and foreign exchange transactions, and the government or central bank will provide liquidity in the foreign exchange market to ensure the stability of the official exchange rate. However, due to the fact that official exchange rates often do not match market supply and demand, unofficial exchange rates have emerged.

Non-official exchange rates are usually freely determined by market participants based on supply and demand. This exchange rate is closer to the actual market situation, so it is more widely used in informal economic activities. Unofficial exchange rates are usually traded on the black market or through informal channels, such as foreign exchange exchanges, underground banks, etc. The formation of the unofficial exchange rate is affected by market factors such as economic conditions, political stability, capital flows, etc.

The existence of a dual Exchange rate regime often reflects the instability or immaturity of the economic system. It may lead to market distortions and unfair competition as different exchange rate systems may bring different profit margins to different participants. In addition, the dual Exchange rate regime will also increase the complexity of foreign exchange management, increase the risk of government intervention, and may lead to uncertainty about the exchange rate and distrust among investors.

The dual exchange rate system is more common in some countries in the transition period of their economic systems or where Foreign exchange controls are relatively strict. This system can help governments or central banks control the foreign exchange market, maintain the balance of payments, and maintain monetary stability. However, with economic development and the gradual relaxation of Foreign exchange controls, many countries have gradually abolished the dual exchange rate system and adopted the single exchange rate system. A single exchange rate system means that there is only one official exchange rate, which is more in line with market supply and demand, reducing the instability of the foreign exchange market and the uncertainty of capital flows.
