Why does the dollar fall and gold rise?
When the dollar falls, gold tends to rise, because there is a negative correlation between gold and the dollar. In other words, when the dollar depreciates, the price of gold tends to rise, while when the dollar appreciates, the price of gold may fall.
This is because the US dollar is the main currency in the international foreign exchange market, and many investors use it to buy stocks, bonds and other assets in other countries. When the dollar falls, it means that other countries' currencies are relatively more valuable, so their assets become more attractive. Investors may therefore buy stocks, bonds and other assets of other countries, which will lead to a decline in demand for gold.
However, the negative correlation of gold and the dollar is not absolute. In some cases, gold and the dollar may rise or fall at the same time, depending on the specific market conditions. In addition, other factors such as geopolitical risks, inflation expectations and monetary policy will also affect the prices of gold and dollars.
