The benchmark 10-year U.S. Treasury yield is facing renewed downward pressure from one of the oldest cross-asset signals – the copper-to-gold ratio.

After dropping to 0.11 (multiplied by 100), the ratio has briefly surged higher before continuing the downtrend. Although the signal is not as clean as it once was, a sharp turn might indicate a brief drop in the 10-year yield.

Still Has a Pulse

Beyond the trading floors, the short momentum potential got academic backing too. Professor Dror Parnes from Texas AM University found that this ratio often contains short-term predictive information for the 10-year Treasury yield, typically over lags of one to five days.

The research found the relationship is strongest when markets aren’t overwhelmed by crisis shocks – explaining the decoupling in the aftermath of the COVID-19 intervention. In quieter regimes, the ratio and the 10-year remain coordinated.

The current setup is notable as a prolonged compression in the ratio might suggest the 10-year yield has overshot, leaving room for – at least a temporary pullback. The 10-year chart itself shows a rising wedge forming – a pattern that typically breaks to the downside.

Physical Scarcity and Monetary Scarcity

The ratio’s low reading does not necessarily mean copper is weak. The red metal has rallied sharply, supported by power-grid investment, AI data centers, defense demand and mine-supply constraints. Sprott Asset Management analyst Jacob White said forces beyond the traditional business cycle are reshaping the market.

"Copper is breaking away from the traditional industrial cycle," White wrote.

But gold has risen faster. Spot bullion has traded above $4,500 an ounce, supported by central banks buying roughly 1,000 tons annually, sovereign debt concerns and investors fleeing currency debasement.

Gold’s marginal buyers are typically investors and not manufacturers. Higher prices may curb jewelry demand, but they do not necessarily reduce demand from institutions seeking a monetary hedge.

However, a copper rally still has an industrial ceiling. The industry is fighting back with product redesigns, aluminum substitution, and increased recycling efforts. Gold lacks such constraints, and that asymmetry has kept the ratio depressed.

Treasury Buybacks Add Pressure

Near-term catalysts are also stacking up. The recent Treasury intervention shows how far the administration is willing to go to keep yields under control.

Treasury Secretary Scott Bessent has made clear he is watching the benchmark rate closely. "My job is to be the nation’s top bond salesman, and Treasury yields are a strong barometer for measuring success in this endeavor," he said last November. He has also said he wants the 10-year yield to carry a "3" handle.

At the same time, copper’s acute squeeze is easing. London Metal Exchange on-warrant inventories surged by more than 50% in three days, while the cash-to-three-month backwardation collapsed from extreme levels.

"The deliveries alleviate the fears of extreme nearby tightness for now, and LME inventories will be closely watched for signals on price movements," Benchmark analyst Albert Mackenzie said.

Trading the Compression

The key takeaway is that, after a preferably one more push higher – when the rising wedge breaks, the yields might compress toward policy-preferred levels of 4%.

Gold may continue to outpace copper as falling real yields reduce bullion’s opportunity costs. If the yield decline persists, mining majors or broad vehicles such as VanEck Gold Miners ETF (NYSE:GDX) offer leveraged exposure.

Key watchpoints include LME warehouse flows, Treasury auction tails and central-bank reserve accumulation.
