How Currency Exchange Rates Move
An exchange rate is the price of one currency expressed in terms of another. Exchange rates are constantly moving, influenced by economic data, central bank policy, trade flows, and market sentiment.
What Moves Exchange Rates
Key drivers include interest rate differentials (higher rates attract capital), inflation differentials, trade balances, political stability, and market speculation. Central bank interventions can also cause sharp short-term moves in currency values.
Fixed vs. Floating Exchange Rates
In a floating rate system (like the USD, EUR, GBP), rates are determined by supply and demand in forex markets. In a fixed or pegged system, a government or central bank maintains the currency at a set rate against another currency or basket of currencies.
Bid, Ask, and Spread
When exchanging currency, the bid price is what a buyer will pay, and the ask price is what a seller wants. The spread (the difference between the two) represents the profit for the exchange service. Tighter spreads are typically found in large interbank transactions.
How to Get the Best Exchange Rate
Avoid airport kiosks and hotel desks, which offer the worst rates. Online services, specialist forex brokers, and bank transfers typically offer rates closer to the interbank mid-market rate. Always compare before converting large amounts.
