1944. The history of the dollar pegged to gold can be traced back to the signing of the Bretton Woods Agreement in 1944. According to the agreement, the dollar is linked to gold, and the fixed price of gold is $35 per ounce. The US government guarantees that foreign central banks can exchange dollars at this price, and vice versa. This system is called "BrettonWoodsSystem" and lasts until 197 1. President Nixon of the United States announced the cancellation of the direct exchange relationship between the US dollar and gold, that is, the "yellow gold standard system", which is also the basis of the current international monetary system. Therefore, it can be said that the historical period of the dollar pegged to gold is from 1944 to 197 1 year.
