Exchange Rate
Forex Basics
An exchange rate is the price at which one currency can be converted into another, and it is exactly what forex traders speculate on as it rises and falls.
What is an exchange rate?
An exchange rate is simply the price of one currency expressed in terms of another. It answers a single question: how much of the quote currency does it take to buy one unit of the base currency? Every currency pair you see quoted — EUR/USD, GBP/JPY, AUD/CAD — is displaying a live exchange rate.
For example, an EUR/USD exchange rate of 1.0850 means 1 euro currently converts to 1.0850 US dollars. A minute later it might be 1.0855, meaning the euro has become marginally more expensive in dollar terms.
Floating vs. fixed exchange rates
Most major currencies — the US dollar, euro, British pound, Japanese yen, and others — trade under a floating exchange rate regime, meaning their value is set continuously by supply and demand in the open market, moving in real time based on economic data, interest-rate expectations, and capital flows. Some countries instead peg their currency to another (a fixed or pegged exchange rate), holding it at or near a set level through central-bank intervention. Floating rates are what create the price movement that forex traders aim to profit from.
Worked example
Imagine you’re planning a trip and need to convert $1,000 into euros. At an exchange rate of 1.0850 (EUR/USD), your $1,000 converts to roughly €921.66 ($1,000 ÷ 1.0850). If the rate later moves to 1.1000, that same $1,000 would only convert to about €909.09 — the dollar has become relatively stronger, buying fewer euros. This everyday currency-conversion logic is identical to what happens, at much larger scale and with leverage, inside a forex trade.
Why it matters to a trader
The exchange rate is the number every trading decision hinges on: entries, exits, stop-loss and take-profit levels, and profit/loss are all ultimately just the difference between two exchange-rate snapshots in time. Since even small moves matter, traders measure exchange-rate changes in pips rather than whole currency units, giving a consistent, granular way to talk about price action.
Quick recap
- An exchange rate is the price of one currency in terms of another.
- Floating rates move continuously with market supply and demand; some currencies are pegged instead.
- Every forex trade is a bet on how the exchange rate of a pair will change.
