Is the Copper–Gold Ratio a Reliable Main Indicator on Charges?

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 truthful worth yield is beneath 2%.” Because the divergence endured 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’ concentrate on the ratio’s connection to Treasury yields, we have to perceive the market catalysts that affect this relationship, significantly the US greenback, as a result of there are indicators that the ratio’s utility might weaken underneath sure market situations.

Copper and gold are each dollar-denominated commodities that exhibit destructive correlations with the forex. Day by day knowledge 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.

Because the 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 way 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 increased.

In a Goldilocks economic system with no coverage shift, nonetheless, destructive shocks ought to gasoline flight-to-haven flows to each the greenback and Treasuries. That is what occurred in the course of the commodity rout of 2014 and 2015 and once more in the course of 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 international greenback demand pushed by geopolitical components may act as headwinds for each the greenback and Treasury securities. In “Warfare and Peace,” Credit score Suisse analyst Zoltan Pozsar mentioned geopolitical currents may scale back international reserve managers’ urge for food for greenback 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. International holdings of US Treasuries have already declined lately, and Pozsar suspects this development might persist.
