What Is a Currency Exchange?
Let me explain what a currency exchange is: it's a licensed business where you can swap one currency for another. You usually do this over the counter at a teller station, and you'll find these spots in places like airports, banks, hotels, and resorts.
These exchanges earn their keep by charging a small fee and through something called the bid-ask spread.
You might hear them called a 'bureau de change' or 'casa de cambio.' Just don't mix them up with the foreign exchange (forex) market—that's where traders and big financial institutions handle currency trades.
Key Takeaways
As I see it, the main points are straightforward: currency exchanges let you swap currencies, and you can find them in physical spots like banks and airports, or increasingly online. Fees can vary a lot, so sometimes your credit card might cost less than dealing with adjusted exchange rates. They make money from fees and the bid-ask spread, and remember, this isn't the same as the forex market for trading currencies.
How a Currency Exchange Works
Currency exchange businesses, whether they're physical locations, online platforms, or even peer-to-peer setups, let you buy another country's currency using your own.
Take this example: if you have U.S. dollars and need Australian dollars, you take your dollars or bank card to the exchange and buy the Australian ones with them.
How much you get depends on the international spot rate, which is a daily value set by banks that trade currencies.
Charge for Service
On top of any service fee, the exchange will tweak the rate by a percentage to guarantee a profit.
Suppose the spot rate for U.S. to Australian dollars is 1.2500—that means you'd get 1.25 Australian dollars per U.S. dollar at spot. But the store might adjust it to 1.20, so you get 1.20 Australian dollars per U.S. dollar, effectively charging you 5 cents on the dollar.
Since transactions aren't at the spot rate and depend on the exchange's profit margin, you might find it's cheaper to just use ATM or credit card fees abroad instead of exchanging ahead. I advise you to estimate your trip spending and compare what you'd save with different methods.
Important Note on Currency Convertibility
You need to know that currency convertibility is key in our global economy—it's vital for international trade, finance, and commerce. If a currency isn't convertible, it creates major hurdles for trade, foreign investment, and even tourism.
Where to Find a Currency Exchange
You can find currency exchanges in all sorts of forms and places. It could be a small standalone business in a single office, or part of a chain with booths at airports. Big international banks often provide these services at their tellers.
Airports are prime spots because of all the travel— they let you grab destination currency right before you leave and swap back leftovers when you return. But heads up: airport rates are generally pricier than what you'd get at a city bank.
These days, going cashless is more common, with some banks offering cards that load multiple currencies with minimal fees. Offshore ATMs work well if you're with a global bank like HSBC, which has machines across Europe, the Americas, Asia, the Middle East, and North Africa.
Online, you'll see currency exchange services from banks, forex brokers, or other financial outfits.
Tip for Travelers
When you're traveling abroad, watch for country-specific fees. For instance, before July 2020, Cuba hit tourists with a 10% tax when buying Cuban convertible pesos with U.S. dollars.
Bid-Ask Spreads in the Retail Forex Market
As I mentioned, exchanges make money two ways: fees and the bid-ask spread. The bid is what the dealer pays for a currency, and the ask is what they sell it for.
Consider Ellen, an American heading to Europe. The quote might be EUR 1 = USD 1.30 / 1.40. The higher price, 1.40, is what she pays to buy euros. For EUR 5,000, she'd hand over USD 7,000.
Now, say Katelyn is back from Europe with EUR 5,000 to sell. She gets the bid price of 1.30, so USD 6,500. The dealer pockets USD 500 profit from the spread.
Keep this in mind: the higher price is what you pay to buy, the lower is what you get when selling.
Can I Get Foreign Currency at a Bank?
Yes, banks can often help, especially if you're a customer. At Bank of America, for example, account holders can order online and get it shipped same day.
What Is the Cheapest Way to Buy Foreign Currency?
Start with your local bank or credit union—they usually have the best rates. You might also use your credit card at a foreign ATM without transaction fees.
Can I Just Use a Credit Card When I Travel Abroad?
If your card is accepted, sure—you can use it for hotels, restaurants, and such. Check with your bank on foreign fees, though. Still, it's smart to have some cash, so plan accordingly.
The Bottom Line
In essence, a currency exchange is a business that lets you swap currencies. If you're in the U.S. heading to Europe, you'd buy euros with dollars there. They charge fees and profit from the bid-ask spread on each deal.
