Key Takeaways
- • Gold has rallied more than 100 percent over the past two years (measured by LBMA Gold Price PM Index) and now trades at or near all-time highs, approximately 150 percent above its 10-year average, raising questions about valuation sustainability.
- • Global regulated carbon markets have grown into a liquid, institutional asset class with over $1 trillion in annual traded value, attracting major financial institutions and expanding coverage from global banks and research desks.
- • KraneShares' carbon ETF index (KRBN) has outperformed the S&P 500 over both the past five years and throughout 2025, demonstrating competitive return characteristics alongside portfolio diversification benefits.
- • Carbon exhibits low correlations to equities, gold, and other traditional risk assets, positioning it as a potential diversification tool similar to gold's historical role in institutional portfolios.
- • Carbon markets introduce a distinct scarcity dynamic through supply caps that tighten over time, offering different portfolio characteristics compared to traditional commodities and potentially addressing investor concerns about gold's current valuation extremes.
Summary
Gold's exceptional performance over the past two years—a rally exceeding 100 percent as measured by the LBMA Gold Price PM Index—has established the precious metal at or near all-time highs. However, this strength has created a valuation challenge: gold currently trades more than 35 percent above its 200-day moving average and approximately 150 percent above its long-term 10-year average. By multiple metrics, gold appears more extended than U.S. equities, prompting institutional investors to reassess how the asset may perform going forward and whether alternative allocations might offer comparable portfolio benefits.
According to KraneShares, global regulated carbon markets have emerged as a potential substitute allocation. The carbon market has achieved significant institutional scale, with over $1 trillion in annual traded value, increasing participation from major financial institutions, and expanding research coverage from global banking desks. This evolution has transformed carbon into a liquid, institutional-grade asset class accessible through ETF structures, comparable to how ETFs democratized access to gold exposure.
Carbon's return profile warrants attention: KraneShares reports that its carbon ETF index has outperformed the S&P 500 over both the past five years and in 2025. More importantly for diversified portfolio construction, carbon has demonstrated low correlations to equities, gold, and other traditional risk assets, reinforcing its potential role as a diversifying allocation—a characteristic historically central to gold's appeal in institutional portfolios.
The structural dynamics of carbon markets differ fundamentally from traditional commodities. Rather than relying on geological scarcity, carbon markets introduce scarcity through regulatory supply caps that tighten progressively over time. This mechanism may provide investors with an inflation-sensitive asset class and diversification benefits without exposure to the valuation extremes currently present in gold markets. As institutional allocators contend with gold's extended valuation and debate optimal portfolio hedging strategies amid equity market valuations and geopolitical uncertainty, carbon markets present an alternative institutional asset class worthy of evaluation.
