From the data of 30 years, the international gold-copper exchange rate is in a fluctuation range, rather than unilaterally rising or falling. In 30 years, 1 gram of gold can be exchanged for 2600 grams to 9300 grams of copper. This ratio often depends on the short-term relative increase of gold and copper prices, so it seems to fluctuate greatly. In the long run, 1 g of gold can be exchanged for about 54 12 g of copper. As of June 16, 65,438 grams of gold can be exchanged for 5,964 grams of copper, and the current ratio of gold to copper is slightly higher than the 30-year historical average.

When the international copper price enters a bull market or continues to rise, the ratio of gold to copper tends to decline, which shows that the increase of copper price is often significantly greater than that of gold. From 2003 to 2007, copper price and gold price rose at the same time, but the ratio of gold to copper continued to fall. The relative performance of international copper prices and gold prices during this period may provide some reference for now.
