What is Exchange Rate and How It Works!

Understanding Exchange Rates: From Fluctuations to Profit Margins

At first glance, exchange rates might seem straightforward. They’re just the value of one currency compared to another, right? But in reality, they’re much more complicated than that.

When you’re exchanging money, you’ll find that the rate offered can vary widely between different providers. And to make things even trickier, these rates can change frequently, making it hard to know what you’re really getting.

Why are there so many different rates out there? 

Let’s break it down.

Exchange rates are not just important for individuals traveling or studying abroad. They also have a big impact on entire countries’ economies and global trade. These rates change based on the supply and demand for a specific currency. If lots of people want to buy it, its value goes up. But if there’s too much of it floating around, its value drops.

On a larger scale, the demand for a currency is affected by how confident investors and businesses feel about a country’s political and economic future. 

A strong, stable economy will drive rates up, while uncertainty can cause them to fall.

Exchange rates can be either fixed or floating. Most major countries have floating rates, which means they change with the market. But some countries choose to fix their rates to another currency, like how Bulgaria’s currency is pegged to the Euro.

Comparison of Different Exchange Rates

Exchange rates can vary significantly between different exchange services, and it is essential to compare rates and fees before making an exchange. 

Sell/Buy Rate

The sell rate is the rate at which a currency is sold, while the buy rate is the rate at which a currency is bought. 

For example, if you want to exchange 1 USD to EUR, the sell rate might be 0.94 EUR, and the buy rate might be 1.0646 EUR. This means that if you sell 1 USD, you will receive 0.94 EUR, and if you buy 1 USD, you will pay 1.0646 EUR. 

The difference between the sell and buy rate is known as the spread, which is a profit margin for the exchange service.


The spread is the difference between the buy and sell rate. 

For instance, if the sell rate for 1 USD is 0.94 EUR and the buy rate is 1.0646 EUR, the spread is 0.1246 EUR. This means that for every 1 USD exchanged, the exchange service earns a profit of 0.1246 EUR.


Commission is an additional fee charged by some exchange services for processing the exchange transaction. 

For instance, an exchange service might charge a commission of 1% for exchanging 1000 USD to EUR. This means that for every 1000 USD exchanged, the exchange service earns a profit of 10 EUR.

Cross Rate

A cross rate is the rate at which one currency is exchanged for another currency without involving the domestic currency. 

For instance, if the exchange rate for 1 USD to EUR is 0.94 and the exchange rate for 1 EUR to GBP is 0.8629, the cross rate for 1 USD to GBP is 0.8097. This means that 1 USD can be exchanged for 0.8097 GBP.

Mid Market Rate/Interbank Rate/Spot Rate

The mid-market rate, also known as the interbank rate or spot rate, is the rate at which banks exchange currencies with each other. This rate is the midpoint between the buy and sell rates on the global currency markets and constantly fluctuates.

For instance, the mid-market rate for 1 USD to EUR might be 0.939750, which means that 1 USD can be exchanged for 0.939750 EUR. 

The mid-market rate is the only real exchange rate, and anything else is simply a number made up by the banks, including their slice of profit.

Why do exchange rates fluctuate by providers?

Well, each service wants to make money, so they add their own fees and charges on top of the mid-market rate. Some might claim to have no commission, but they still make money by adjusting their rates.
