Commodities are physical goods traded in bulk — energy (oil, gas), metals (gold, copper), and agriculture (grains, livestock) — held as investments for diversification and inflation exposure. Because storing barrels and bushels is impractical, most commodity investing runs through futures, and the futures mechanics shape returns as much as the commodities themselves.
How commodity investing actually works
Futures-based exposure — the standard route for funds and indices — introduces roll yield: as contracts expire, positions roll into later months, and whether the curve is in contango (later months pricing higher — rolling costs money) or backwardation (later months lower — rolling pays) can dominate long-run returns, which is why an index fund’s return can diverge painfully from the spot-price headline. Alternatives to futures: physical holding (practical mainly for gold and precious metals, via allocated storage and bullion-backed funds — gold behaving as its own monetary asset class more than a commodity), equities of producers (adding corporate risk to commodity exposure), and managed-futures strategies trading commodity trends within hedge-fund-style mandates. The portfolio case rests on two properties with honest asterisks: inflation sensitivity (commodities respond to the same price pressures portfolios need hedging against — effective in inflation shocks like 2021–22, uncompensated drag in disinflationary decades like the 2010s) and diversification (low long-run correlation to stocks and bonds, less reliable in liquidity crises when everything sells). Structural notes for advised accounts: commodity funds using futures often run through offshore subsidiaries or issue K-1s depending on wrapper; direct exposure to producing assets — farmland and timberland, energy royalties and DPPs — is the private-markets cousin, earning operating income rather than riding price alone.
