Which World Bank Group institution administers arbitration under the 1966 Washington Convention?

The World Bank Group institution that administers arbitration under the 1966 Washington Convention is the International Centre for Settlement of Investment Disputes.

ICSID was established by the Convention on the Settlement of Investment Disputes between States and Nationals of Other States. The convention created a specialized framework for resolving investment disputes between governments and foreign investors through conciliation and arbitration.

ICSID does not act like a national court, and it does not automatically hear every investment disagreement. Its jurisdiction generally depends on the consent of the parties and applicable treaty, law, or contract.

The centre is affiliated with the World Bank Group but has a distinct legal role. It is frequently confused with the International Court of Justice, which primarily handles disputes between states under a different institutional framework.
