Should I add a broad commodities fund to protect against inflation?

A broad commodities fund holding energy, metals, and agricultural futures can hedge against surprise inflation because commodity prices often rise when inflation does, and they behaved that way during the 2021 to 2022 inflation spike. But commodities are volatile, produce no income, and have delivered poor long-term returns compared to stocks. Futures-based commodity funds also face roll costs and can carry complex tax reporting, sometimes via a Schedule K-1. If you want an inflation hedge, TIPS or I-bonds from the U.S. Treasury are more direct and less volatile for most people. A small commodities allocation of a few percent can add diversification, but treat it as portfolio insurance, not a wealth builder, and understand you may hold it through long stretches of losses.
