The Copper–Gold Ratio and Greenback Results
Institutional asset managers use the copper–gold ratio as one of many 10-year Treasury yield’s main 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 honest worth yield is beneath 2%.” Because the divergence continued earlier this yr, the copper–gold ratio was, in Gundlach’s phrases, “screaming that the 10-year ought to go decrease.”

However given asset managers’ give attention to 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 beneath sure market situations.
Copper and gold are each dollar-denominated commodities that exhibit detrimental correlations with the foreign money. Day by 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 consumers. Certainly, a robust greenback has a tightening impact on world financial actions, in line with Financial institution for Worldwide Settlements (BIS) evaluation. The next charts bear out this relationship.

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 development, 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 should strengthen the greenback and push short- and longer-term charges larger.
In a Goldilocks economic system with no coverage shift, nevertheless, detrimental shocks ought to gas 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 disaster.” 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 Susceptible to Macro Paradigm Shift
Moreover, shifts in world greenback demand pushed by geopolitical elements might act as headwinds for each the greenback and Treasury securities. In “Warfare and Peace,” Credit score Suisse analyst Zoltan Pozsar mentioned geopolitical currents might cut back international reserve managers’ urge for food for greenback bonds. In such a state of affairs, a weaker greenback might 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 pattern could 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.
