There is a negative correlation internally. When the dollar falls, gold rises, and when gold falls, the dollar tends to rise. Global gold spot and futures prices are priced in US dollars. Therefore, the weakening of the dollar will make gold cheaper in front of non-American investors, and the relationship between the two is negatively correlated. The bad news of the dollar, that is, the threat of inflation, is good news for gold. The Bretton Woods system established after World War II stipulates that the US dollar is the most important international reserve currency. The dollar is directly linked to gold, the currencies of all countries are linked to the dollar, and gold can be exchanged with the United States at the official price of $35 per ounce. This is what we usually call the "gold standard", that is, the currencies of all countries are based on gold. However, due to the revival of Europe and Japan, many countries bought gold in dollars, which led to the collapse of this system, and finally the IMF gave up this system.
