Understanding Exchange Rates for Business
For businesses that operate internationally, exchange rate fluctuations directly affect profitability. A UK company invoicing US clients in USD will find that a 10% USD/GBP rate change affects their effective revenue by 10% when converted back to GBP. Common strategies for managing currency risk: invoice in your home currency (transfers the risk to the customer), forward contracts (lock in an exchange rate for a future date), currency hedging through options, and maintaining multi-currency bank accounts to hold received foreign currency until the rate is favourable. For small businesses, simply invoicing in the customer's currency and converting receipts promptly at the current rate is a pragmatic approach that avoids the complexity of financial instruments.
Frequently Asked Questions
The mid-market rate (also called the interbank rate or spot rate) is the midpoint between the buy and sell rates used by banks when trading currencies with each other. It is the 'true' exchange rate with no markup. Banks, travel agencies, and exchange services add a spread on top of the mid-market rate — this is their fee. When you exchange currency at an airport or bank, the rate offered is typically 2–5% worse than the mid-market rate. Services like Wise (TransferWise) offer rates close to the mid-market rate with explicit fees, which is often cheaper than traditional methods.
Foreign exchange rates change continuously during market hours — they are literally updated every second in live trading. Our converter uses rates updated every few minutes from reliable financial data sources. For large transactions where precise rates matter, check with your bank or broker for the exact rate they will apply at the time of the transaction.
