Key Technical Takeaways

  • The Gold-to-Silver Ratio is simply gold's price divided by silver's, showing how many ounces of silver it takes to buy one ounce of gold.
  • A ratio climbing into the high 80s or 90s has historically flagged silver as cheap relative to gold, often preceding a move back toward the long-run average near 65.
  • A ratio dropping below 50 has historically coincided with strong industrial-driven silver rallies that outpace gold.
  • One common relative-value approach is a paired long-silver, short-gold position sized in equal dollar amounts, aiming to profit from the ratio reverting rather than from either metal's outright direction.

The Gold-to-Silver Ratio (GSR) measures the relative value between gold and silver. It tracks how many ounces of silver buy one ounce of gold, highlighting market mispricings.

1. Calculating the Ratio

The formula is simple: Gold Price per Ounce / Silver Price per Ounce. For example, if Gold (XAU/USD) trades at $1,800/oz and Silver (XAG/USD) trades at $22.50/oz, the ratio is 80.0.

That means 80 ounces of silver equal one ounce of gold.

2. Key ratio bands

When the ratio climbs above 85, historically into the high 80s or 90s, silver is cheap relative to gold, and capital often flows back into it, pulling the ratio toward its multi-decade average of 65. A reading below 50, usually seen during strong industrial rallies, means the opposite: silver is expensive relative to gold. A ratio between 60 and 75 sits in a more normal band, reflecting balanced industrial demand and steady central bank accumulation.

3. Trading Strategy

Traders execute relative value trades by buying XAG/USD and shorting XAU/USD in equal dollar amounts when the GSR reaches upper Bollinger Bands on weekly charts. This hedges dollar risk while capturing ratio mean-reversion.

Frequently Asked Questions

A range of roughly 60 to 75 has historically reflected balanced industrial demand and steady central bank gold accumulation, though the long-run average has shifted over different decades.

Not on its own. A high ratio flags silver as historically cheap relative to gold, but the actual reversion can take weeks or months, so it's typically combined with technical confirmation rather than traded in isolation.

CFTC Rule 4.41 & Risk Disclosure Regulatory Notice

CFTC Rule 4.41 & Risk Disclosure: Hypothetical or simulated performance results have certain inherent limitations. Unlike an actual performance record, simulated results do not represent actual trading. Also, since the trades have not actually been executed, the results may have under-or-over compensated for the impact, if any, of certain market factors, such as lack of liquidity. Trading forex and commodities on margin carries a high level of risk and may not be suitable for all investors.
