International Clearing System

What Does International Clearing System Mean?
A trading system used when a futures contract transaction is entered on an international level. It is designed to promote world trade and market efficiency. Most international clearing transactions are administered by an international clearing house.

Investopedia explains International Clearing System
For example, if a company wanted to purchase a futures contract for wheat from a foreign party, they would need to contact a clearing house, which will use the international clearing system to find another party. The other party, who will assume the opposite position (in this case, the one who is looking to sell the wheat contract) in the futures contract, will have also contacted a clearing house in their respective country, who will also use the international clearing system.
