International Experience of Exchange Rate Systems

During your visits to a bank or a financial institution, you may have noticed a special counter for foreign exchange services. You may have also observed an LED screen or a notice board displaying the exchange rates for various currencies. So, who determines these rates? Well, this is where exchange rate systems come into play. Let us know what fixed exchange rate is.

Exchange Rate

Usually, exchange rates change based on the demand and supply of a currency. If you want to travel abroad, you will have to exchange your currency with your destination’s currency. This will create a demand for that foreign currency. In addition to demand and supply, governments also influence exchange rates. Let’s look at some basic exchange rate systems and how they affect the market.

Free-Floating System

In this system, currency values are purely determined by demand and supply factors in the foreign exchange market. A floating exchange rate is the currency rate between two currencies at any given time. Governments and banks do not influence the currency values in this case.

Let’s now understand how this affects a country’s trade. If a country’s currency value depreciates against other currencies, it means that they will have to pay more for imported goods. Consequently, the imported goods become more expensive. In such a case, buyers will shift to domestic goods. And the demand for the same imported goods will decrease, which converts the country’s balance of trade to a surplus. This surplus then increases the domestic currency’s value as against other currencies in the foreign exchange market.

One of the advantages of a floating exchange rate system is that it is self-regulating. The exchange market by itself controls any major changes in demand and supply. However, this system’s disadvantage is that it is unpredictable. While trading, buyers and sellers from different countries will have to also consider exchange rate fluctuations.

Managed Float System

In a managed float system, governments and banks occasionally participate in the trade of currencies in a bid to control the price of their currency. This may happen only when the governments of countries that follow a free-floating exchange rate system want to prevent sudden major swings in the value of their currencies.

For instance, if a currency’s value is increasing rapidly and there is a consequent reduction in exports, then that country’s government may then intervene to reduce its currency’s value to ensure that the trade is not affected.

Fixed Exchange Rate

Now, let’s take a look at the fixed or ‘pegged; exchange rate system. In this system, the government or the central bank of a country fixes the official exchange rate of its currency against another country’s currency or against gold. This system helps in stabilizing a country’s currency value and maintain low inflation rates. In the fixed exchange rate system, the central bank or the government of a country will buy or sell its own currency in return for the foreign currency it fixes the value to in the foreign exchange market.

The advantage of this system is that a country can remove the unpredictability factor providing more opportunities to its importers and exporters. Following a fixed exchange rate system would help in keeping the exchange rate steady. However, it would require the country to maintain large reserves of the foreign currency it pegs its domestic currency’s rate too. A disadvantage of the fixed exchange rate system is that the country will not be able to adjust its interest rates as needed.
