During World War II, Great Britain and the United States tried to deal with the problem of an international agreement on money. The two countries tried to set up a formal system that everyone would use to exchange money between countries. The system they set up is usually called the Bretton Woods System. (20) The system got this name from the town in New Hampshire in the United States where the international agreement was signed.
The Bretton Woods Agreement was signed in 1944. When it was signed, it seemed to be a good system.
The Bretton Woods Agreement had two main parts. The first part concerned exchange rates. (21) All of the countries that signed the agreement promised to regulate their exchange rates. The countries promised not to change their exchange rates too often. This was a very important part of the agreement. It helped to stabilize the international finance system. The second part of the Bretton Woods Agreement concerned a currency fund. The fund was supposed to help countries that needed currency. (22) All the countries contributed some of their currency to the fund. They could borrow the necessary currency from the fund. This helped all of the member countries to do business with each other. This second part of the agreement was called the International Monetary Fund.
