Jim Wiederhold: Gold, Silver Shining, but Will Industrial Metals Win in 2026?

Key Concepts

• BCOM (Bloomberg Commodity Index): A broad benchmark for commodity market performance, comprised of 25 of the most traded commodities.
• Rebalancing: The annual adjustment of commodity weights within the BCOM based on liquidity and economic significance.
• Liquidity & Economic Significance: The two primary pillars used in BCOM rebalancing, assessing trading volumes and world production respectively.
• Diversification & Continuity: Additional pillars of the BCOM methodology, ensuring a balanced and stable index.
• Stagflation: An economic environment characterized by slow economic growth and rising inflation.
• Sector Rotation: The shift in investment focus from one sector (e.g., precious metals) to another (e.g., industrial metals) based on performance and outlook.
• AI-Driven Demand: The increasing demand for energy and resources driven by the growth of artificial intelligence and data centers.
• Geopolitical Risks: The impact of global political instability on commodity supply chains and prices.

Bloomberg Commodity Index Rebalancing & 2026 Outlook

This discussion with Jim Weerhold, Bloomberg commodity indices product manager, centers on the recent Bloomberg Commodity Index (BCOM) rebalancing and his outlook for commodities in 2026. The BCOM, a benchmark comprised of 25 of the most traded commodities, undergoes an annual rebalancing in January to maintain its alignment with current market conditions.

BCOM Rebalancing Process:

The rebalancing process is rooted in four pillars: liquidity, economic significance, diversification, and continuity. The primary drivers of the recent rebalancing were liquidity and economic significance, assessed through a five-year average analysis of trading volumes and world production. Weights are initially determined with a 2/3 emphasis on liquidity and 1/3 on economic significance, then adjusted with diversification caps and floors (no single commodity exceeding 15% weight). The changes are implemented over a five-day roll period, adjusting weights by 20% daily to minimize market disruption. Governance checks and fallback mechanisms are in place to address extreme scenarios. The index aims for continuity, adapting to market changes gradually.

Impact of 2026 Rebalancing:

The rebalancing led to anticipated reductions in the weights of gold and silver due to their strong price performance in 2025, exceeding the diversification caps. However, the impact on prices was muted by continued strong demand for these precious metals, driven by tailwinds not fully detailed in the conversation. Despite predictions of volatility, the five-day roll period successfully minimized market disruption. The index has now rolled to the new target weights, but these weights can shift throughout the year based on underlying price movements. Gold and silver weights increased significantly in 2025 due to price appreciation, highlighting the dynamic nature of the index.

2026 Commodities Outlook: A Shift Towards Industrial Metals

Weerhold anticipates a potential shift in outperformance from precious metals to industrial metals in 2026. This is partially attributed to the significant gains already realized by precious metals, suggesting a potential for consolidation. More importantly, the fundamental story for industrial metals is strengthening.

Industrial Metals Landscape:

The industrial metals umbrella includes copper, aluminum, nickel, zinc, lead, and tin. Copper is highlighted due to positive supply-demand fundamentals, with forecasts from Bloomberg NEF (BNF) predicting significant deficits. New mine development can take up to 10 years, potentially leading to supply constraints as demand increases. Nickel recently experienced a price surge due to export bans imposed by Indonesia, demonstrating the impact of geopolitical factors on supply. Aluminum is also experiencing rising demand, driven by the energy transition. These metals are crucial components in renewable energy technologies, electric vehicles, wind turbines, and solar panels.

Economic Outlook & Stagflationary Risks:

The current economic environment is characterized by a “climbing the wall of worry” scenario, with both copper and gold reaching all-time highs simultaneously. This suggests a potential for stagflation – slow economic growth coupled with rising inflation. Commodities, with the highest inflation beta of any asset class, are historically strong performers during stagflationary periods, particularly industrial metals. The current economic situation mirrors patterns observed in the 1960s and 70s, with a period of low inflation followed by a significant spike.

Energy & AI Demand

Increased demand for energy, fueled by the rapid growth of artificial intelligence (AI) and the associated buildout of data centers, is expected to benefit commodities used in power generation. The expansion of AI infrastructure requires significant investment in chips, rare earth metals, and other essential materials. Increased productivity driven by AI is projected to further boost overall commodity demand.

Risks & Diversification

Geopolitical risks and weather-related events pose significant threats to commodity supply chains. The trend towards nearshoring and reversing globalization is increasing business costs and creating vulnerabilities in sourcing materials. Unprecedented geopolitical events are disrupting supply and driving up prices. Weerhold emphasizes the role of commodities as a diversifier in investment portfolios, offering uncorrelated returns to other asset classes, particularly in a potentially volatile equity market.

Notable Quote:

“Commodities use for inflation hedging typically, but also as a diversifier. So, you know, they're they're uncorrelated to other asset classes and uh you know, if people are concerned about the runup in valuations and equities, you know, now is uh at a time where people probably start considering it if they haven't already.” – Jim Weerhold

Conclusion:

The BCOM rebalancing reflects the ongoing evolution of commodity markets. Looking ahead to 2026, the outlook suggests a potential shift in leadership from precious metals to industrial metals, driven by strong fundamentals, increasing demand from the energy transition and AI, and the potential for a stagflationary environment. Geopolitical risks and supply chain disruptions remain key concerns. Commodities offer diversification benefits and a potential hedge against inflation, making them a compelling asset class for investors to consider.
