a supranational currency imagined by Keynes between 1940–1942 and which the UK proposed to introduce after WWII; it could then be used in international trade as a unit of account within a multilateral clearing system—the International Clearing Union—which would also have to be founded
An international fund would be created to play the role of the world's central bank and issue its currency--the bancor, as Keynes provisionally named it.
The key role played by this new international central bank – the ICU – would be to manage flows of money between states, and to use a new currency, bancor, as the relevant currency. (In other words, a neutral currency, not the currency of one imperial power.)
