What is the Difference Between Exchange Rate and Interest Rate?
🆚 Go to Comparative Table 🆚The difference between exchange rate and interest rate lies in their definitions and their relationship with each other.
Exchange Rate:
- Exchange rates are relative and are expressed as a comparison of the currencies of two countries.
- They play a vital role in a country's level of trade and are critical to most every free market economy in the world.
- A higher exchange rate can worsen a country's balance of trade, while a lower exchange rate can improve it.
Interest Rate:
- Interest rates are the cost of borrowing money or the return on savings.
- They can often fluctuate and have a big impact on both borrowers and savers.
- The demand for money, the balance of trade between a country's imports and exports, and other factors impact interest rates.
The relationship between exchange rates and interest rates is that higher interest rates in a country can increase the value of that country's currency relative to other currencies. This is because 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 value. However, the impact of higher interest rates is mitigated if inflation in the country is much higher than in others or if additional factors serve to drive the currency down.
Comparative Table: Exchange Rate vs Interest Rate
The main difference between exchange rate and interest rate lies in their definitions and functions. Here is a table summarizing the key differences between the two:
| Feature | Exchange Rate | Interest Rate |
|---|---|---|
| Definition | The exchange rate is the cost of exchanging one country's currency for another. | The interest rate is the percentage of a loan or deposit paid or earned over a specific period. |
| Purpose | Exchange rates are used to convert one currency into another and fluctuate constantly due to market demand. | Interest rates are used to determine the cost of borrowing or the return on investment for funds. |
| Market | The foreign exchange market determines exchange rates, which are influenced by various factors such as political stability, economic performance, and market sentiment. | Interest rates are set by central banks or financial institutions and can be influenced by factors such as inflation, economic growth, and monetary policy. |
| Relationship | Exchange rates can be affected by interest rate differences between countries, as the interest rate parity theory suggests that the difference between the interest rates of two countries can influence their exchange rates. | No direct relationship exists between exchange rates and interest rates, as they serve different purposes in the financial market. |
In summary, exchange rates are used to convert currencies and are determined by the foreign exchange market, while interest rates are used to determine borrowing costs or investment returns and are set by central banks or financial institutions. Although there is no direct relationship between the two, the interest rate parity theory suggests that interest rate differences between countries can influence exchange rates.
