Judging from the global economic situation, the world economic growth rate may rebound slightly this year, but the overall recovery is weak. The volatility of international financial markets and commodity markets has intensified, and non-economic factors such as geopolitics have a greater impact, and there are still many uncertain factors. With the strengthening of the US dollar, the prices of commodities such as gold, non-ferrous metals and oil are all running at a low level, and the low operation of gold prices will become the "new normal" in the next few years.
