Gold-Silver Ratio

Silver is cheap relative to gold by historical standards. Ratios above 80 are historically elevated. The ratio reached 125 in April 2020 — the highest on record since reliable modern data begins. High ratios have historically preceded periods where silver outperforms gold, though the timing of mean-reversion is unpredictable.

Silver is expensive relative to gold by historical standards. Ratios below 50 have been rare since the end of the silver standard. The 1980 low of approximately 14:1 was driven by the Hunt Brothers' attempt to corner the silver market — an extreme and non-recurring event. A ratio below 50 today would represent a historically compressed relationship.

1. Relative Supply

Gold production is approximately 3,500 tonnes per year; silver production is approximately 25,000 tonnes per year (USGS Mineral Commodity Summaries 2024). Silver is far more abundant as a newly mined metal — roughly 7:1 in annual production weight. However, the gold-silver price ratio is structurally much higher than the supply ratio because of differences in monetary status, industrial demand, and investment behaviour.

2. Industrial Demand

Approximately 50% of silver demand is industrial — solar panels, electronics, medical applications, and electrical contacts (The Silver Institute, World Silver Survey 2024). Gold's industrial use represents approximately 7–10% of total demand (WGC Gold Demand Trends 2024). Silver's industrial demand makes it sensitive to the global economic cycle in a way that gold is not — silver tends to underperform gold during economic downturns and outperform during strong industrial expansion.

3. Monetary Status

Gold is held as a reserve asset by more than 70 central banks globally, as documented in IMF International Financial Statistics. Silver is not held as an official monetary reserve by any major central bank. This difference in monetary status is the single largest structural driver of the ratio's current level relative to pre-20th century history. When both metals had legal monetary status under bimetallism, their ratio was legislated at 15:1 to 16:1 in most countries.

4. Historical Bimetallic Standard

Roy Jastram's definitive historical study "The Golden Constant" (Yale University Press, 1977; updated edition with Jill Leyland, 2009) documents the history of the gold-silver ratio across four centuries of English and American monetary history. Under bimetallism — where both metals were used as legal money — governments legislated a specific gold-silver exchange ratio, typically 15:1 to 16:1 in France and the US under the Coinage Act. The current ratio of approximately 80–90 reflects the de-monetisation of silver that was completed by the early 20th century.

What is a "normal" gold-silver ratio?

There is no single normal ratio — it has varied from ~14:1 (1980, Hunt Brothers silver squeeze) to 125:1 (2020, COVID-19 crisis). The 20-year average from approximately 2004 to 2024 is around 68:1. The ratio above 80 is considered historically elevated relative to the post-2000 era, though it has traded above 80 for extended periods.

Is a high gold-silver ratio bullish for silver?

A high ratio indicates silver is cheap relative to gold by historical standards. Historically, extremely high ratios (above 90–100) have tended to revert toward lower levels over time — meaning silver has outperformed gold after periods of very high ratios. However, the timing of this reversion is unpredictable, and silver can remain "cheap" for years. This is a relative value observation, not an investment recommendation.

Why was the ratio so low historically (15:1)?

Under bimetallism — the monetary system where both gold and silver were legal tender — most major economies legislated a specific ratio between the metals (typically 15:1 or 16:1). The US Coinage Act of 1792 set the ratio at 15:1. France's bimetallic system used 15.5:1. When silver was de-monetised in the late 19th and early 20th centuries, the legal price floor was removed, and silver's price fell to reflect only its industrial and investment demand. Roy Jastram's "The Golden Constant" (1977) documents this history in detail.

What caused the 2020 ratio peak of 125:1?

The COVID-19 crisis in March-April 2020 caused a sharp divergence: gold, as a monetary safe-haven asset, held its value relatively well as investors fled to safety. Silver, which has approximately 50% industrial demand, fell sharply as the pandemic threatened global industrial production. The combination of gold's safe-haven rally and silver's industrial demand collapse pushed the ratio to its highest recorded level of approximately 125:1 in April 2020.
