Silver vs Gold: Trading the Gold-Silver Ratio
One number has described the relationship between the two monetary metals for centuries. How traders use the ratio's extremes to time the white metal.
By the Pocketfolio Research Desk
The gold-silver ratio is simply the price of an ounce of gold divided by the price of an ounce of silver — the number of silver ounces needed to buy one of gold. It has been quoted since antiquity, and while it no longer enjoys official status, its extremes remain among the most watched mean-reversion signals in the commodity world.
What the ratio tells you
Over the modern era the ratio has spent much of its time between roughly 55 and 80. Readings above 80 have historically marked silver as cheap relative to gold — the March 2020 panic briefly pushed it beyond 120, an all-time extreme, before silver outperformed dramatically over the following year. Low readings, toward 40–50, have marked the opposite: silver euphoria, as in 2011.
The logic is structural. Gold is primarily a monetary asset; silver is half monetary, half industrial. In risk panics, money hides in gold first and the ratio spikes. In reflation and growth phases, silver's industrial demand kicks in and the ratio compresses.
How traders express it
The purist's trade is a pairs position: long XAG/USD against short XAU/USD when the ratio is historically stretched, betting on convergence rather than outright direction. Simpler expressions work too — overweighting silver exposure via SLV when the ratio exceeds 80, or simply using a high ratio as a quality filter that upgrades long-silver setups.
Respect the volatility difference. Silver behaves like gold with leverage: daily swings of 3% are routine, and position sizes should be cut accordingly. The ratio gives you the when. Sizing discipline still decides whether you are around to collect.
