Despite surging in 2025, gold remains a minor component of major commodity baskets, highlighting its distinct function as a monetary asset separate from industrial commodities and impacting investor strategies.
Gold’s place in broad commodity baskets remains surprisingly small, even after a year in which the metal surged and traders watched index rebalancing closely. The S&P GSCI gives gold a 7.2% weight, while the Bloomberg Commodity Index places it at 14.9%, a structure that reflects futures-market liquidity and production data more than gold’s role as a monetary asset. That distinction matters because gold’s market is not driven the same way as oil, copper or wheat, and its value is shaped far more by its above-ground stock and its appeal as a store of wealth.
The mismatch is especially clear when set against the size of gold trading itself. The World Gold Council says the global market averaged $373 billion in daily trading volume in 2025, with a large share taking place over the counter and much of the rest through futures. By contrast, commodity index methodologies lean heavily on exchange-traded contracts and annual output, which works well for industrial raw materials but tends to miss the scale and structure of gold ownership.
That helps explain why gold often behaves differently from the rest of the commodity complex. World Gold Council data for 2025 shows investment demand made up a large share of total gold demand, alongside jewellery and central bank buying. In other words, when economic stress rises or monetary confidence weakens, demand for gold can strengthen even as industrial commodities soften. Bloomberg’s 2026 commodities outlook suggested industrial metals may have a stronger year than precious metals, backed by supply deficits, infrastructure spending and power demand from artificial intelligence and data centres, reinforcing the idea that commodities and gold are serving different portfolio roles.
The return gap between physical gold and futures-based commodity funds also highlights the cost of using the wrong instrument for the job. Commodity ETFs usually track futures, which must be rolled forward as contracts expire. In contango, when later-dated futures cost more than near-dated ones, that process creates a persistent drag known as negative roll yield. Industry research cited by GoldSilver said physically backed gold products delivered far stronger returns in 2025 than broad futures-based commodity funds, which captured only a fraction of gold’s rally.
Recent market activity underlined how much the weighting decision can matter. Bloomberg reported in January that gold steadied as traders positioned for annual commodity index rebalancing, with passive funds selling precious-metals futures to match new target weights. S&P Dow Jones Indices and Bloomberg also disclosed 2026 rebalancing changes, with gold’s weight adjusted again, showing that even when precious metals gain ground, they remain a modest part of the broader commodity universe. For investors, the lesson is simple: a commodity ETF is not a substitute for owning gold directly. It offers exposure to the business cycle and inflation sensitivity, but physical gold in allocated storage is designed for monetary protection, liquidity and long-term purchasing power.
