TD Securities: CTA Buying Skew Amplifies Copper Scarcity and Price Volatility
TD Securities warns that structural copper scarcity in 2025 is being amplified by a pronounced buying skew from Commodity Trading Advisors (CTAs). Rising demand from electrification — EVs, renewable energy and grid upgrades — is outpacing supply expansion, while declining ore grades, regulatory delays and capital constraints slow new mine output. TD’s models show CTAs and other systematic trend-followers have built near multi-year high net-long positions in copper futures, triggering buy orders as prices breach technical thresholds (e.g., 20/50-day moving averages, volatility breakouts). Low exchange inventories (LME/COMEX) and backwardated curves align fundamentals with technical signals, so algorithmic buying can magnify uptrends. Risks include rapid CTA-driven unwinds if momentum reverses, which could accelerate downswings. Key monitoring points: exchange inventory levels, Chinese import and PMI data, progress on major mining projects (Chile, Peru, DRC), and technical price levels that could flip systematic flows. Traders should note heightened volatility potential, consider hedging or scaled execution strategies, and watch CTA positioning data and physical stock indicators for early signs of trend persistence or reversal.
Bullish
TD Securities highlights a convergence of strong physical fundamentals and systematic financial buying. Rising demand from electrification and constrained mine supply create a genuine bullish backdrop for copper. CTAs and other trend-following funds have accumulated large net-long positions; their algorithmic buying at technical breakpoints tends to amplify uptrends, especially when inventories are low and forward curves show backwardation. Historically, similar conditions (tight physical market + heavy trend-following flows) have produced sharp rallies in commodity prices. In the short term, this increases upside momentum and volatility — upward moves can be accelerated by algorithmic buying. In the medium to long term, sustained price strength depends on whether new mine supply, scrap recycling, or demand slowdowns emerge. A key risk is a momentum reversal: CTAs can quickly switch to selling, which would intensify declines. For traders, the net effect is a bullish bias with elevated risk of large swings; recommended actions include active hedging, watching inventory/CTA positioning data, scaling entries, and using stop strategies to manage algorithm-driven volatility.
