Exchange rate

3 key takeaways:

• An exchange rate specifies how much one currency is worth in terms of another currency.
• Exchange rates are influenced by factors such as interest rates, inflation, political stability, and economic performance.
• Exchange rates impact international trade, investment, and economic stability.

What is an exchange rate?

An exchange rate is the price at which one currency can be exchanged for another. It is a fundamental concept in international finance, as it determines the relative value of different currencies and influences cross-border economic activities. Exchange rates are quoted as pairs, such as EUR/USD or GBP/JPY, indicating how much of the quote currency is needed to purchase one unit of the base currency.

There are two main types of exchange rates: fixed and floating. Fixed exchange rates are set and maintained by a country’s government or central bank, while floating exchange rates are determined by the market forces of supply and demand.

How do exchange rates work?

Exchange rates fluctuate based on various factors that affect the supply and demand for different currencies. Key factors include:

1. Interest Rates: Higher interest rates in a country can attract foreign capital, leading to an appreciation of the currency as investors seek higher returns.
2. Inflation Rates: Lower inflation rates typically strengthen a currency’s value, as its purchasing power increases relative to currencies with higher inflation rates.
3. Economic Performance: Strong economic growth and stability attract investment, boosting demand for the currency and causing it to appreciate.
4. Political Stability: Countries with stable political environments tend to have stronger currencies, as stability reduces the risk for investors.
5. Balance of Payments: A surplus in the balance of payments increases demand for a country’s currency, leading to appreciation, while a deficit can cause depreciation.
6. Market Speculation: Traders’ expectations about future currency movements can influence exchange rates. If traders believe a currency will strengthen, they may buy it, driving up its value.

Key features of exchange rates:

Exchange rates have several important implications:

• Trade and Investment: Exchange rates affect the cost of importing and exporting goods and services. A stronger currency makes imports cheaper and exports more expensive, while a weaker currency has the opposite effect.
• Tourism: Exchange rates influence the cost of traveling abroad. A favorable exchange rate makes travel cheaper for tourists from a stronger currency country.
• Foreign Debt: Countries with foreign-denominated debt must consider exchange rates when repaying debt. A weaker domestic currency increases the cost of servicing foreign debt.
• Inflation and Monetary Policy: Exchange rates can impact inflation and monetary policy. A depreciating currency can lead to higher import prices and inflation, influencing central bank policies.
