Referenzkurs
Referenzkurs is a term used in finance and accounting to denote a benchmark exchange rate that serves as a reference for valuing, converting, or settling financial quantities denominated in foreign currencies. It is not necessarily the live market rate but a defined rate published or determined for a specific purpose, often on a daily or contractual basis.
In practice, referenzkurs provides a consistent basis for translating foreign currency items into the domestic currency
Common sources include central banks (national or regional) and official data services that publish reference rates.
The concept is related to general terms such as spot rate, forward rate, and reference rate used
