An exchange rate is a rate at which one currency will be exchanged for another currency and affects trade and the movement of money between countries.
Exchange rates are impacted by both the domestic currency value and the foreign currency value. In July 2022, the exchange rate from U.S. Dollars to the Euro was 1.02, meaning it takes $1.02 to buy €1.
Key Takeaways
An exchange rate is a rate at which one currency will be exchanged for another currency.
Most exchange rates are defined as floating and will rise or fall based on the supply and demand in the market.
Some exchange rates are pegged or fixed to the value of a specific country's currency.
Exchange rate changes affect businesses by changing the cost of supplies that are purchased from a different country, and by changing the demand for their products from overseas customers.
The exchange rate between two currencies is commonly determined by the economic activity, market interest rates, gross domestic product, and unemployment rate in each of the countries. Commonly called market exchange rates, they are set in the global financial marketplace, where banks and other financial institutions trade currencies around the clock based on these factors. Changes in rates can occur hourly or daily with small changes or in large incremental shifts.
An exchange rate is commonly quoted using an acronym for the national currency it represents. For example, the acronym USD represents the U.S. dollar, while EUR represents the euro.To quote the currency pair for the dollar and the euro, it would be EUR/USD. In the case of the Japanese yen, it's USD/JPY or dollar to yen. An exchange rate of 100 means that 1 dollar equals 100 yen.
How Exchange Rates Fluctuate
Exchange rates can be free-floating or fixed. A free-floating exchange rate rises and falls due to changes in the foreign exchange market.A fixed exchange rate is pegged to the value of another currency. The Hong Kong dollar is pegged to the U.S. dollar in a range of 7.75 to 7.85. This means the value of the Hong Kong dollar to the U.S. dollar will remain within this range.
Exchange rates have what is called a spot rate, or cash value, which is the current market value. Alternatively, an exchange rate may have a forward value, which is based on expectations for the currency to rise or fall versus its spot price.
Forward rate values may fluctuate due to changes in expectations for future interest rates in one country versus another. If traders speculate that the eurozone will ease monetary policy versus the U.S., they may buy the dollar versus the euro, resulting in a downward trend in the value of the euro.
Exchange Rate Example
A traveler to Germany from the U.S. wants 200 USD worth of EUR when arriving in Germany. The sell rate is the rate at which a traveler sells foreign currency in exchange for local currency. The buy rate is the rate at which one buys foreign currency back from travelers to exchange it for local currency.
If the current exchange rate is 1.05, $200 will net €190.48 in return.
In this case, the equation is: dollars ÷ exchange rate = euro
$200 ÷ 1.05 = €190.48
After the trip, suppose €66 is remaining. If the exchange rate has dropped to 1.02, the change from euros to dollars will be $67.32.
€66 x 1.02 = $67.32
The Japanese yen is calculated differently. In this case, the dollar is placed in front of the yen, as in USD/JPY.
The equation for USD/JPY is: dollars x exchange rate = yen
If a traveler to Japan wants to convert $100 into yen and the exchange rate is 110, the traveler would get¥11,000. To convert the yen back into dollars one needs to divide the amount of the currency by the exchange rate.
$100 x 110 = ¥11,000.00
-or-
¥11,000.00/110= $100
How Do Exchange Rates Affect the Supply and Demand of Goods?
Changes in exchange rates affect businesses by changing the cost of supplies that are purchased from a different country, and by changing the demand for their products from overseas customers.
What Is the FOREX?
The forex market, or foreign exchange market, allows banks, funds, and individuals to buy, sell or exchange currencies. The market operates 24 hours, 5.5 days a week, and is responsible for trillions of dollars in daily trading activity as traders look to profit by betting that a currency's value will either appreciate or depreciate against another currency.
What Is a Restricted Currency?
Exchange rates can differ within the same country. Some countries have restricted currencies, limiting their exchange to within the countries' borders and often there is an onshore rate and an offshore rate. A more favorable exchange rate can often be found within a country's borders versus outside its borders and a restricted currency has its value set by the government. China is an example of a country that has this rate structure and a currency that is controlled by the government. Every day, the Chinese government sets a midpoint value for the currency, allowing the yuan to trade in a band of 2% from the midpoint.
The Bottom Line
An exchange rate is a rate at which one currency will be exchanged for another currency. While most exchange rates are floating and will rise or fall based on the supply and demand in the market, some exchange rates are pegged or fixed to the value of a specific country's currency. Exchange rate changes affect businesses and the cost of supplies and demand for their products in the international marketplace.

What Is a Currency Peg? A currency peg is a policy in which a national government or central bank sets a fixed exchange rate for its currency with a foreign currency or a basket of currencies and stabilizes the exchange rate between countries. The currency exchange rate is the value of a currency compared to another.
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.
The exchange rate gives the relative value of one currency against another currency. An exchange rate GBP/USD of two, for example, indicates that one pound will buy two U.S. dollars. The U.S. dollar is the most commonly used reference currency, which means other currencies are usually quoted against the U.S. dollar.
These transactions mainly take place in foreign exchange markets, marketplaces for trading currencies. Currencies increase in value when lots of people want to buy them (meaning there is high demand for those currencies), and they decrease in value when fewer people want to buy them (i.e., the demand is low).
Currency valuations fluctuate constantly, driven by the flow of funds between markets. The two biggest drivers are central bank policies (interest rates set by the U.S. Federal Reserve and its counterparts in Europe, England, Japan and elsewhere); and economic growth relative to inflation.
The Kuwaiti dinar is the strongest currency in the world, with 1 dinar buying 3.26 dollars (or, put another way, $1 equals 0.31 Kuwaiti dinar). Kuwait is located on the Persian Gulf between Saudi Arabia and Iraq, and the country earns much of its wealth as a leading global exporter of oil.
In a floating regime, exchange rates are generally determined by the market forces of supply and demand for foreign exchange. For many years, floating exchange rates have been the regime used by the world's major currencies – that is, the US dollar, the euro area's euro, the Japanese yen and the UK pound sterling.
Because of the twenty-four hour global nature of currency markets, exchange rates are constantly shifting from day to day and even from minute to minute, sometimes in small increments and sometimes quite dramatically.
The Iranian Rial is considered the world's lowest currency due to factors such as economic sanctions limiting Iran's petroleum exports, which has resulted in political instability and depreciation of the currency. 2. Which currency holds the title of the highest valuation globally?
When the Federal Reserve increases the federal funds rate, it typically increases interest rates throughout the economy, which tends to make the dollar stronger. The higher yields attract investment capital from investors abroad seeking higher returns on bonds and interest-rate products.
There can be many contributing factors to a weak currency but a nation's economic fundamentals are usually the primary reason. Export-dependent nations may actively encourage a weak currency in order to boost their exports. Currencies can also be weakened by domestic and international interventions.
Typically, the least busy times of the week are Mondays, mid-week and the weekend (excluding Friday). These days have the lowest number of transfers in the week, so you might expect to see less fluctuation in the mid-market rate.
Prior to 1971, the US dollar was backed by gold. Today, the dollar is backed by 2 things: the government's ability to generate revenues (via debt or taxes), and its authority to compel economic participants to transact in dollars.
Some of the countries where a dollar is worth the most money include Mexico, Peru, Chile, and Colombia. It's possible to exchange dollars for local currency in these countries at favorable exchange rates.
Persistent changes in terms of trade (such as oil producers usually experience) and differences in fiscal policies, tariffs, and even financial development can also help explain why REERs can differ across countries.
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.
1 A lower-valued currency makes a country's imports more expensive and its exports less expensive in foreign markets. A higher exchange rate can be expected to worsen a country's balance of trade, while a lower exchange rate can be expected to improve it.
