Playing the Ratio Game: Gold and Silver

March 16, 2020

Gold price has surged to multi-year high recently, generating massive interest in this investment amidst market uncertainties and low interest rates. This article will give you an appreciation of gold and silver, and the gold/silver ratio.



Known as the “Crisis Commodity” for its ability to retain value during financial and geopolitical uncertainties, gold has appreciated in value over the past one year.

However, gold has a less popular sister known as “silver”. As prices of gold and silver tend to move in tandem, potential investment opportunities arise when silver prices differ significantly from that of gold.



Apart from gold, silver is another metal that could provide protection in times of uncertainty. Here are some reasons why you can also consider silver for investment.

  • Silver can provide some inflation hedge in the long run. However, do take note that the precious metals market does not always track inflation well in the near term.
  • Silver is more affordable as its price is much lower than gold.
  • Silver’s metallic characteristics make it a key component in industrial uses such as solar panels. The growing concern for global warming and push for renewable energy sources could lead to an increased demand for silver.
  • Price of silver is affected by supply and demand. Silver is rarely found alone and more commonly found in ores that contain lead, copper, gold and other metals, which are also commercially valuable. In 2018, copper, zinc and lead form about 61% for silver mine production by source metal. (see Figure 1 below from Statista). When the economy starts to slow down, the production for copper, zinc and lead also decreases, indirectly reducing the supply for silver. The difference between supply & demand can lead to price appreciation of silver.

  • There is potentially a higher appreciation value of silver in times of economic uncertainty as compared to gold – this can be explained by the gold/silver ratio which will be discussed later.

We can use the gold/silver ratio to explore possible investing or trading strategies. We can see from Figure 2 that the gold/silver ratio ranges from around 31.6 to 100. A high gold/silver ratio means that the value of gold is relatively expensive as compared to silver and vice versa.


Gold/Silver Ratio Investing Example

When you notice that the gold/silver ratio is higher as compared to historic averages, you can consider purchasing silver. When the ratio is lower as compared to historic average, you might wish to consider getting into gold instead. Using this process, you can continue to build up your inventory of gold and silver over time. This strategy may take a couple of years but is useful if you are intending to hold precious metals commodities in your portfolio. Of course, some people prefer to trade instead.
