The Bretton Woods Agreement was signed in 1944, the purposed was to prevent the currency to escape between countries, and also to limit the international speculation, thus to stabilize the international currency. Before this agreement was signed, the gold remittance standard system which was widely used since 1876 - was leading the international economy system until the First World War. In the gold remittance system, the currency was at the stable level under the support of the gold price. The gold remittance system has abolished the old time king and the ruler which depreciates the currency value unlawfully, which will lead to inflation.
But, the gold remittance standard system is certainly imperfect. Along with a country economic potentiality enhancement, it can import massive products from overseas, until it exhausts the gold reserve of certain country. It resulted the supply of the currency reduces, the interest rate raises, the economic activity will start to decline until it reaches the recession limit. Finally, the commodity price falls to the valley, gradually attracts other countries to stream in, massively rushes to purchase this country commodity. This will pour gold into this country, this will increase this country currency supplies quantity, and it will reduce the interest rate, and will create the wealth. This is so called the "the prosperity - decline” pattern and is the circulation of the gold remittance standard system, until the trade circulation and the gold freedom was broken by the First World War.
