Exchange Rates: What They Are, How They Work, Why They Fluctuate? ›

There are two main —fixed and . In a fixed exchange rate system, a government or central money maintains a currency's value, allowing little to no fluctuation. In contrast, floating exchange rates are based on current supply and demand forces within the foreign market.

One of the main factors that can cause currency fluctuation is inflation. When a country experiences high inflation, its currency becomes less valuable because it can buy fewer goods and services. This makes it less attractive to investors, and the demand for that currency decreases, causing its value to drop.

What Are Exchange Rates Based on? Exchange rates for floating currencies are based on the supply and demand of one currency versus another. The exchange rates between two currencies shift as the supply and demand for each change.

Definition: Changes in Exchange Rate Explained

The 'Changes in Exchange Rate' refers to the fluctuations in the value of one country's currency, compared to that of another country. Think of it as a price - the price of a country's currency in terms of another currency.

Currency fluctuation is the changes in the value of one currency relative to another. This fluctuation results in changes in exchange rates, which determine how much one currency can be traded for another in the global market.

Foreign exchange rates are constantly changing. We update our rates at least once every business day, based on current market conditions.

When the value of a currency changes, prices for goods traded using that currency can be affected. A currency appreciation (when the value increases over time) results in a lower effective price for imported goods; currency depreciation (when the value decreases over time) translates to higher import prices.

A country's net exports or imports impact currency value and exchange rates. A domestic country that exports more goods than it imports will experience a higher demand for its currency, and thereby, will see its exchange rate increase relative to other foreign currencies.

Flexible rate of exchange is the rate which is determined by the supply-demand forces in the foreign exchange market. It is also called 'free exchange rate' or 'floating exchange rate' as it is determined by the free play of supply and demand forces in the international money market.

Overview of Exchange Rates

A higher-valued currency makes a country's imports less expensive and its exports more expensive in foreign markets.1 A lower-valued currency makes a country's imports more expensive and its exports less expensive in foreign markets.

Higher interest rates tend to attract foreign investment, increasing the demand for and value of the home country's currency. Conversely, lower interest rates tend to be unattractive for foreign investment and decrease the currency's relative value.

Technology changes that cause productivity increases in goods commonly traded between countries, called tradables, are thought to be one of those factors. Because productivity increases lead to lower production costs, the REERs would rise to maintain equilibrium.

A currency's strength is determined by the interaction of a variety of local and international factors such as the demand and supply in the foreign exchange markets; the interest rates of the central bank; the inflation and growth in the domestic economy; and the country's balance of trade.
