keresztárfolyam

Keresztárfolyam refers to the exchange rate between two currencies that are not the US dollar. When a bank or financial institution needs to determine the value of one currency in relation to another, and neither is the USD, they will use a keresztárfolyam. This is typically achieved by converting both currencies into the US dollar first, and then using those US dollar values to calculate the exchange rate between the two original currencies. For example, if one wants to find the exchange rate between the Euro and the Japanese Yen, they would first find the EUR/USD rate and the JPY/USD rate. Then, they would use these two rates to derive the EUR/JPY cross rate. This method is common because the US dollar is a major global reserve currency and its exchange rates against most other currencies are readily available and frequently quoted. The resulting keresztárfolyam is therefore an indirect rate derived from two direct rates against the US dollar. Financial markets often publish these cross rates, making them easily accessible for traders and businesses involved in international transactions. Understanding and utilizing keresztárfolyam is crucial for international finance and currency exchange operations where direct quotes between the involved currencies are not always available or practical.
