Medium of Exchange
The monetary function that allows people to trade through a commonly accepted intermediary instead of relying on direct barter.
Medium of exchange is the function of money that allows people to trade without direct barter.
Exchange Becomes Easier When Acceptance Is Shared
Barter requires a double coincidence of wants: each participant must want exactly what the other person offers.
A widely accepted medium of exchange separates the act of selling from the act of buying, allowing each person to trade at different times and with different counterparties.
What Is a Medium of Exchange?
A medium of exchange is something people accept not necessarily because they want to consume it, but because they expect they can later exchange it for something else.
This shared expectation allows a monetary network to form.

A trade requires each party to directly want what the other party offers.
A seller accepts the monetary medium and later uses it to buy from someone else.

An effective medium of exchange usually benefits from broad acceptance and practical transferability.
