What Is Trade?

Trade is the voluntary exchange of goods or services between different economic actors. Since the parties are under no obligation to trade, a transaction will only occur if both parties consider it beneficial to their interests.

 

Trade can have more specific meanings in different contexts. In financial markets, trade refers to purchasing and selling securities, commodities, or derivatives. Free trade means international exchanges of products and services without obstruction by tariffs or other trade barriers.
