1, the dollar rose. Gold is generally used as a reserve currency as a substitute for the dollar, and the prices of the two are in opposite directions. In other words, a stronger dollar means more room for appreciation. People usually choose to buy dollars and sell gold, and the price of gold tends to fall. If the Fed cuts interest rates and the dollar depreciates, the price of gold tends to rise.

2. Gold production has increased substantially. The price of gold is influenced by the relationship between supply and demand, and the price of gold is based on this relationship. If the output of gold increases significantly, the price of gold will be affected and fall back. On the contrary, if the output of gold decreases, the price of gold will rise.

The local interest rate has increased. Interest rates are closely related to gold. If the domestic interest rate is high, it is necessary to consider whether it is worthwhile to lose interest income to buy gold. Once the deposit interest rate is raised, the willingness to buy gold will not be so high, and the price of gold will also fall.

4. Inflation. Usually, the higher inflation in major western countries, the greater the demand for gold as a safe haven, and the higher the world gold price. Among them, the inflation rate in the United States is the most likely to affect the change of gold.

5. The economic situation is good. When the economy is prosperous and the financial system is stable, people's confidence in gold will decrease, investment demand will decrease and the price of gold will also decrease. On the contrary, because gold has the function of a fund refuge, when the world financial crisis occurs or the financial system is in turmoil, funds will be more inclined to invest in gold, and the price of gold will rise immediately.
