Definition
A medium of exchange is an intermediary instrument utilized to facilitate the purchase and sale of goods and services between parties. To be effective, it must serve as a standard of value that all transaction participants agree upon. In contemporary economies, currency acts as the predominant medium of exchange, although historically, various commodities (like gold) have filled this role.
