Frequently asked questions
How is a cross rate calculated?
Divide one currency's rate by the other's, both quoted against a shared currency. A rate of 1.30 divided by 1.10 gives a cross rate of about 1.1818.
Why use cross rates?
Not every currency pair trades directly, so a cross rate is built from each currency's rate against a major like the dollar. It reveals the implied exchange rate between the two.
What is a cross exchange rate in simple terms?
It is the rate between two currencies that share no direct quote. You take their rates against a common third currency. The tool divides one by the other to find the link. The shared currency cancels, leaving the rate between the two.
Why do I divide the two rates?
Both rates measure each currency against the same common one. Dividing one by the other removes that shared currency. What remains is the price of one currency in the other. It is the same logic as cancelling a common factor in a fraction.
What counts as the common currency?
It is the single currency that both of your rates are quoted against. Often it is a major one used widely in markets. The key is that it is identical on both sides of the calculation. If the two rates use different bases, the cross rate will be wrong.
