Copper / Gold Ratio vs. 10-Year Treasury Yield (Growth vs. Safe Haven)
Jeffrey Gundlach Macroeconomic Growth Proxy: Cyclical Industrial Demand vs. Monetary Safe-Haven Hoarding (1995–2026)
The scaled Copper/Gold ratio (Copper $/lb divided by Gold $/oz multiplied by 1,000) stands at 1.538, while the 10-Year US Treasury yield trades at 4.67%. Historically popularized by DoubleLine, this ratio serves as a pure market-based barometer of cyclical economic growth versus defensive monetary hedging. A ratio of 1.54 historically correlates with a 10Y Treasury yield near 3.85%, indicating benchmark yields currently carry an 82 bps term-premium/fiscal risk markup.

1. The Mechanics of the Copper/Gold Barometer
Copper is the preeminent cyclical industrial commodity, embedded across electrical grids, housing, automotive manufacturing, and renewable energy infrastructure. Its price rises during periods of accelerating industrial production and capital investment. Conversely, gold possesses negligible industrial utility, trading primarily as a non-debasable store of value, safe-haven liquidity reserve, and monetary hedge. The ratio between the two separates economic growth momentum from monetary debasement.
2. Empirical Co-Movement with Nominal Treasury Yields
For nearly thirty years, DoubleLine Capital's Jeffrey Gundlach popularized the observation that the Copper/Gold ratio tracks the US 10-Year Treasury yield with remarkable statistical precision. When cyclical demand outpaces monetary fear (ratio rising), bond yields rise as inflation and growth expectations firm. When fear eclipses industrial activity (ratio falling), safe-haven bond buying compresses benchmark yields.
3. Modern Divergence: The Fiscal Term Premium
In 2024–2026, the Copper/Gold ratio dropped to 1.54 even as nominal 10-Year yields remained stubbornly elevated near 4.67%. This gap of over 80 basis points indicates that Treasury yields are no longer solely driven by cyclical real GDP growth expectations; rather, unprecedented peacetime US fiscal deficits, heavy debt issuance auctions, and sovereign supply indigestion are keeping long-term yields elevated above their traditional cyclical anchors.
