The Copper–Gold Ratio and Greenback Results
Institutional asset managers use the copper–gold ratio as one of many 10-year Treasury yield’s leading indicators. Certainly, because the unfold between bond yields and the ratio widened within the third quarter of 2022, DoubleLine Capital CEO and Chief Funding Officer Jeffrey Gundlach cited the connection, observing that “the 10-year US Treasury fair value yield is below 2%.” Because the divergence persevered earlier this 12 months, the copper–gold ratio was, in Gundlach’s phrases, “screaming that the 10-year should go lower.”
Copper–Gold Ratio vs. 10-Yr Treasury Yield
However given asset managers’ deal with the ratio’s connection to Treasury yields, we have to perceive the market catalysts that affect this relationship, notably the US greenback, as a result of there are indicators that the ratio’s utility could weaken below sure market situations.
Copper and gold are each dollar-denominated commodities that exhibit detrimental correlations with the forex. Every day information from 2020 to 2023 point out a correlation coefficient of –0.10 between copper futures and the Greenback Index. Gold’s correlation with the Greenback Index confirmed a coefficient of –0.31 over the identical interval.
These metrics make intuitive sense: The greenback’s appreciation relative to native currencies ought to enhance commodity costs for non-dollar patrons. Certainly, a strong dollar has a tightening effect on world financial actions, based on Financial institution for Worldwide Settlements (BIS) evaluation. The next charts bear out this relationship.

Gold vs. Greenback Index
For the reason that greenback is a shared enter of each copper and gold valuations, the ratio of gold and copper largely neutralizes this impact as demonstrated by their –0.01 correlation with the Greenback Index. Whereas this magnifies copper’s sensitivity to financial progress, it additionally will increase monitoring error relative to such dollar-influenced devices as US Treasuries.
Treasury Yield and Greenback Valuation: Nuanced Dynamics
The correlation coefficient of the 10-year Treasury yield and the Greenback Index reached as excessive as 0.82 over our 2020 to 2023 evaluation interval. Regardless of such optimistic correlation, the greenback’s relationship with Treasury yields is far more nuanced.
Throughout an easing cycle instituted by a dovish US Federal Reserve, a weaker greenback tends to correlate with decrease Treasury yields. Conversely, a hawkish Fed must strengthen the greenback and push short- and longer-term charges larger.
In a Goldilocks economic system with no coverage shift, nonetheless, detrimental shocks ought to gasoline flight-to-haven flows to each the greenback and Treasuries. That is what occurred throughout the commodity rout of 2014 and 2015 and once more throughout the 2019 “repo crisis.” The copper–gold ratio and different dollar-sensitive metrics ought to diverge from charges given their optimistic correlation with the greenback.

Copper–Gold Ratio Is Weak to Macro Paradigm Shift
Moreover, shifts in world greenback demand pushed by geopolitical factors may act as headwinds for each the greenback and Treasury securities. In “War and Peace,” Credit score Suisse analyst Zoltan Pozsar mentioned geopolitical currents could reduce foreign reserve managers’ appetite for dollar bonds. In such a situation, a weaker greenback may co-exist with weaker Treasuries and exacerbate the divergence between the copper–gold ratio and the 10-year yield. Overseas holdings of US Treasuries have already declined in recent times, and Pozsar suspects this trend may persist.

Because the greenback and Treasuries more and more reply to world macro catalysts, the copper–gold ratio and different, much less dollar-sensitive, indicators could overlook rising drivers. And that would erode their utility as indicators.
