Forex cross rates are the exchange rates between two currencies that are calculated using a third currency (usually the U.S. dollar), instead of being directly quoted.
🔑 How it works:
- In the foreign exchange (forex) market, most currencies are quoted against the USD (because it’s the world’s reserve currency).
- But when you want the exchange rate between two non-USD currencies, that’s called a cross rate.
Example:
Suppose you want the exchange rate between the Euro (EUR) and the Japanese Yen (JPY):
- You know:
- EUR/USD = 1.10 (1 Euro = 1.10 U.S. dollars)
- USD/JPY = 150.00 (1 U.S. dollar = 150 yen)
- To get EUR/JPY (cross rate): $$
\text{EUR/JPY} = \text{EUR/USD} \times \text{USD/JPY} = 1.10 \times 150 = 165
$$
✅ So 1 Euro = 165 Yen.
Why it matters:
- Cross rates are important for global trade, travel, and forex trading.
- Traders use them to find arbitrage opportunities (profiting from price differences across markets).
- Businesses use them for currency conversion when dealing in two non-USD currencies.
👉 In short: Forex cross rates let you convert between two currencies that don’t have a direct quote by using a common base currency, usually the U.S. dollar.
