What Happens When the Copper-Gold Ratio Collapses?
Copper-gold ratio collapse signals growth concerns and is often called "Dr. Copper's recession warning". What happens when the industrial-to-monetary metals ratio crashes?
Trigger: Copper Price (Global) copper-gold ratio falls to multi-year lows
Current Status
Right now, Copper Price (Global) is at $12,951.35, flat +0.0% over 30 days and +0.0% over 90 days.

The Mechanics
The copper-gold ratio measures pounds of copper per one ounce of gold. Copper is the industrial-growth proxy ("Dr. Copper" for its economic PhD). Gold is the monetary and safe-haven metal. Their ratio captures the balance between growth and fear in global macro.
When copper outperforms gold, growth is strong and the economy is expanding. When gold outperforms copper (ratio collapsing), growth concerns dominate: industrial demand is weakening, recession risk is rising, or monetary policy is easing (supporting gold real-yield channel). The copper-gold ratio correlates strongly with the 10Y Treasury yield and is often cited as a macro-growth proxy.
A copper-gold ratio at multi-year lows signals broad-based growth concern. It typically precedes or coincides with Fed easing cycles, yield-curve steepening (bull steepeners), and equity market corrections. Conversely, ratio bottoms often mark recession troughs and precede equity-market rallies.
Historical Context
The copper-gold ratio hit cycle lows in early 2016 (coincident with Chinese stimulus concerns), December 2018 (Fed pause), March 2020 (COVID crash), October 2022 (hard-landing fears), and mid-2024 (growth concerns alongside AI optimism). Each low was followed by ratio expansion as either growth recovered or monetary easing supported both metals but copper benefited more from industrial demand recovery. The 2020 ratio bottom at 0.15 was followed by a move to 0.28 (87% gain) by 2022. The 1998 ratio bottom at 0.12 preceded a 200% move over two years.
Market Impact
Copper-gold ratio correlates 0.7+ with 10Y yields. Ratio collapse typically coincides with 10Y yields falling 50-150 bps. Ratio expansion historically precedes yield rises.
Ratio collapse typically coincides with equity market drawdowns of 5-20%. Growth-sector weakness (cyclicals, industrials) leads the decline. Ratio bottoms often mark S&P lows.
EEM sensitivity to copper is particularly high (Latin America, Chile, Peru). EEM underperforms SPY during ratio collapse. Recovery in the ratio typically leads EEM bounces.
China is the largest copper consumer. FXI and copper-gold ratio move closely together. Chinese stimulus announcements can drive ratio expansion rapidly.
Copper-gold ratio collapse often signals growth weakness that supports Fed easing. Historical pattern: ratio bottoms 3-6 months after Fed pivot to cuts (as easing transmits to growth).
XLI underperforms during ratio collapse. Capital goods orders weaken, industrial production stalls. Defensive sectors (XLU, XLP) outperform during the copper-gold ratio compression phase.
What to Watch For
- -10Y yield divergence from copper-gold ratio (either direction)
- -Chinese manufacturing PMI below 49
- -Copper inventories on LME rising sharply
- -Fed pivot to cuts (often coincides with ratio bottom)
- -Global PMI composite below 48 confirming industrial weakness
How to Interpret Current Conditions
Track the copper-gold ratio alongside the 10Y Treasury yield (mean-reversion trades), Chinese PMIs, and global manufacturing indicators. Ratio divergences from yields can signal either macro regime change or temporary dislocations. Combine with the ISM Manufacturing index and global PMIs for confirmation.

Frequently Asked Questions
What triggers the "the Copper-Gold Ratio Collapses" scenario?▾
The scenario activates when copper-gold ratio falls to multi-year lows. The trigger metric and its current reading are shown on this page, so the live state of the scenario is always visible rather than abstract. Convex tracks this trigger continuously and flags crossings within hours.
Which assets are most affected when this scenario unfolds?▾
The Market Impact section lists the full asset-by-asset response, but the primary affected assets include: 10Y Treasury Yield (DGS10), US Equities (S&P 500), Emerging Markets (EEM), Chinese Equities (FXI). Each asset has historically shown a characteristic pattern of response that is described in detail on the per-asset deep-dive pages linked below.
How often has this scenario played out historically?▾
The copper-gold ratio hit cycle lows in early 2016 (coincident with Chinese stimulus concerns), December 2018 (Fed pause), March 2020 (COVID crash), October 2022 (hard-landing fears), and mid-2024 (growth concerns alongside AI optimism). Each low was followed by ratio expansion as either growth recovered or monetary easing supported both metals but copper benefited more from industrial demand recovery. The 2020 ratio bottom at 0.15 was followed by a move to 0.28 (87% gain) by 2022. The 1998 ratio bottom at 0.12 preceded a 200% move over two years.
What should I watch for next?▾
The most important signals to track while this scenario is active: 10Y yield divergence from copper-gold ratio (either direction); Chinese manufacturing PMI below 49. The full list is on this page under "What to Watch For." These signals are the ones that historically preceded the scenario either resolving or accelerating.
How should I interpret the current state of this scenario?▾
Track the copper-gold ratio alongside the 10Y Treasury yield (mean-reversion trades), Chinese PMIs, and global manufacturing indicators. Ratio divergences from yields can signal either macro regime change or temporary dislocations. Combine with the ISM Manufacturing index and global PMIs for confirmation.
Is this a prediction or a conditional analysis?▾
This is conditional analysis, not a prediction that the scenario will happen. Convex describes what typically follows once the trigger fires and shows how close or far the current data is from that trigger. The page is informational; it does not constitute financial advice.
