(1) Dollars and gold

The impact of the dollar on the gold market is mainly in two aspects. One is that the US dollar is the quoted currency in the international gold market, so it is negatively related to the price of gold. Assuming that the value of the gold price itself has not changed, the price of the gold price will rise if the dollar falls. On the other hand, gold is an alternative investment tool for dollar assets. In fact, in the years before 2005, one of the main factors for the continuous rise of gold prices was the sharp decline of the US dollar for three consecutive years. According to the statistics of the historical data in the past 30 years, the negative correlation between the US dollar and gold is about 80%. From the data of the past ten years, as shown in the following figure, from the correlation chart of the US dollar and gold from 1995 to 2003, it can be seen that the relationship between the US dollar and gold is approaching-1%. Therefore, when we analyze the trend of gold price, the change of US dollar exchange rate is an important reference.
