How Currency Exchange Rates Work
Currency exchange rates represent the price of one currency in terms of another. They fluctuate constantly based on economic data, interest rate decisions, inflation, political events, and global market sentiment. The rates in our converter reflect mid-market rates — the midpoint between what buyers and sellers are willing to trade at in the interbank market. This is the truest exchange rate available, but it is not the rate you will typically receive when exchanging money. Banks, airports, and currency services add a markup on top to make a profit.
Mid-Market Rate vs. What You Actually Get
When you exchange currency at a bank or airport kiosk, the rate you receive is typically 2–8% worse than the mid-market rate. For small amounts this difference is minor. For larger transfers — sending money internationally or converting currency for a major purchase — the spread can cost hundreds of dollars. Services like Wise, Revolut, and similar fintech platforms typically offer rates much closer to mid-market, often with significantly lower fees than traditional banks or exchange bureaus.
Best Practices for Currency Exchange
Avoid airport exchange counters — rates are notoriously bad, sometimes 10–15% worse than mid-market. Credit cards with no foreign transaction fees often give you interbank-level rates and are one of the best ways to pay abroad. If you need local cash, use a local ATM with your debit card rather than a currency exchange service. And when asked whether to pay in your home currency or the local currency while abroad, always choose the local currency — this avoids dynamic currency conversion, which adds another layer of markup.
Frequently Asked Questions
What is the strongest currency in the world?
The Kuwaiti Dinar (KWD) is consistently the highest-valued currency relative to the US dollar. 1 KWD is worth approximately $3.25 USD. This is largely due to Kuwait's oil wealth and fixed exchange rate policy.
Why do exchange rates change?
Exchange rates change based on supply and demand in global currency markets, influenced by interest rate decisions, inflation data, economic growth, political stability, and trade balances.
