What do precious metals ratios signal?

Precious metals ratios compare the prices of gold, silver, platinum, and copper to each other, providing insights into macro sentiment, inflation expectations, and industrial demand conditions. Because these metals have different demand profiles (gold is primarily monetary/safe-haven, silver and platinum span monetary and industrial, copper is almost entirely industrial), their relative prices reveal how markets are weighing financial safety versus economic growth.

The gold-silver ratio (gold price divided by silver price) historically averages around 60-70 but has ranged from below 20 to above 120. When the ratio is elevated (above 80), it typically signals extreme risk aversion, as gold's safe-haven demand outpaces silver's industrial demand. When the ratio compresses toward or below its historical average, it suggests confidence in industrial and economic expansion. The ratio spiked above 120 during the March 2020 COVID panic, then declined as the economic recovery took hold.

The gold-copper ratio (gold price divided by copper price) is closely watched as a macro indicator because it distills the tension between safe-haven flows (gold) and global growth expectations (copper). Rising gold-copper ratios correlate with falling Treasury yields, widening credit spreads, and equity market weakness. Some analysts use the gold-copper ratio as a leading indicator for the 10-year Treasury yield, arguing that the ratio captures the same growth and inflation expectations that determine long-term interest rates.

The gold-platinum ratio is another significant measure. Platinum has historically traded at a premium to gold due to its rarity and industrial demand (catalytic converters, industrial processes). When gold trades at a sustained premium to platinum, as it has since 2015, it reflects both structural challenges to platinum demand (the shift from diesel vehicles, which use platinum catalysts, to electric vehicles) and strong monetary demand for gold. For investors, extreme readings in these ratios often present mean-reversion opportunities, though the timing of reversion is inherently uncertain and ratios can remain at extreme levels for extended periods.
