The rise and fall of gold price in London and the changing trend of gold price are the result of the joint action and comprehensive game of many influencing factors in the market, which is quite complicated but also particularly simple. As far as a single factor is concerned, there are four main factors that affect the trend of gold prices:

1, the trend of the dollar. The exchange rate of US dollar is one of the important factors that affect the fluctuation of gold price. Usually, the trend of the dollar and the trend of gold are negatively correlated. However, they are all "hard currencies" in the world, buying dollars in times of peace and prosperity and buying gold in times of war and danger. If you take gold, you will give up the dollar, and if you take the dollar, you will give up gold. This means that if the dollar is strong and there is a great chance of appreciation, people will definitely like it more. When the dollar weakens in the foreign exchange market, the price of gold will strengthen.

2. In times of war and political turmoil, gold has always been regarded as a safe-haven investment. One of the reasons is that in times of war and political turmoil, the increase in demand for gold will stimulate the price of gold to rise.

3. World Financial Crisis When the financial system of the United States and other western countries is unstable, world funds will be invested in gold, and the demand for gold will increase, and the price of gold will rise. At this time, gold played the role of a financial refuge. On the contrary, when the financial system is stable, investors' confidence in gold will be greatly reduced, which will lead to a decline in the price of gold.
