USCI is the ticker symbol for the United States Commodity Index Fund, an exchange-traded fund (ETF) that tracks a broad basket of commodities. Managed by USCF Investments, the fund aims to give investors diversified exposure to the commodity markets, including energy, metals, agriculture, and livestock, through a single investment.
How USCI Works
USCI tracks the SummerHaven Dynamic Commodity Index Total Return, which takes a rules-based approach to selecting commodity futures contracts. Rather than holding a fixed set of commodities in predetermined weights (as many traditional commodity indexes do), the index evaluates 27 commodity futures markets each month and selects 14 based on signals like backwardation, a market condition where futures prices are lower than current spot prices. Commodities in backwardation have historically offered better roll returns, meaning the fund can potentially avoid some of the drag that hurts other commodity funds when they regularly replace expiring contracts with more expensive ones.
This dynamic selection process is the key differentiator. A static commodity index might hold large allocations to crude oil or natural gas regardless of market conditions. USCI rotates into the commodities showing the most favorable pricing signals each month, which can shift its portfolio substantially over time. In one month the fund might lean heavily toward agricultural commodities; in another, metals or energy might dominate.
What the Fund Holds
USCI does not buy physical barrels of oil or bushels of wheat. It invests in futures contracts, which are agreements to buy or sell a commodity at a set price on a future date. The fund rolls these contracts forward before expiration, maintaining continuous exposure without ever taking physical delivery. Between futures positions, the fund holds its collateral in Treasury bills and other short-term government securities, which generate a small amount of interest income on the side.
The 27 eligible commodities span four broad categories: energy (crude oil, natural gas, heating oil, gasoline, and others), precious and industrial metals (gold, silver, copper, aluminum), agriculture (corn, soybeans, wheat, sugar, coffee, cotton), and livestock (live cattle, lean hogs). At any given time, 14 of these make it into the portfolio.
Tax Structure and K-1 Filing
USCI is structured as a limited partnership for U.S. income tax purposes, not as a traditional fund that sends you a 1099 form at year end. Instead, the fund issues a Schedule K-1 to each shareholder. This means the fund’s income, gains, losses, and deductions flow through directly to you, and you’re responsible for reporting your share on your own tax return.
This has a few practical consequences. K-1 forms often arrive later than standard 1099s, sometimes not until March or even early April, which can delay your tax filing. The reporting itself is more complex than a simple 1099 for dividends or capital gains. If you hold USCI in a taxable brokerage account, you may owe taxes on income the fund generated even in a year when you didn’t sell any shares. Many investors hold K-1 issuing funds in tax-advantaged accounts to simplify things, though there are separate considerations (like unrelated business taxable income) that can apply to IRAs holding partnership interests above certain thresholds.
Who USCI Is Designed For
Commodity funds like USCI appeal to investors looking for diversification beyond stocks and bonds. Commodities often move differently from equities, and they can serve as a hedge against inflation since rising prices for raw materials tend to push commodity returns higher. USCI’s dynamic approach to selecting futures contracts makes it particularly attractive to investors who want commodity exposure but are concerned about the performance drag that static commodity index funds sometimes experience.
That said, commodity futures funds carry meaningful risks. Commodity prices can be extremely volatile, driven by weather events, geopolitical disruptions, supply chain changes, and shifts in global demand. The fund’s monthly rotation can help with roll costs, but it doesn’t eliminate the underlying price risk of the commodities themselves. And because the fund uses futures rather than holding physical assets, its returns won’t perfectly mirror spot commodity prices over long periods.
How to Buy USCI
USCI trades on the NYSE Arca exchange just like a stock. You can buy and sell shares throughout the trading day at market prices through any standard brokerage account. There’s no minimum investment beyond the price of a single share. Like all ETFs, you’ll pay the fund’s expense ratio (deducted from the fund’s assets, not billed to you separately) plus any trading commissions your broker charges, though most major brokerages now offer commission-free ETF trades.
Before purchasing, check the fund’s current expense ratio and recent holdings on the USCF Investments website, since the portfolio composition shifts monthly based on the index methodology. Reviewing the most recent K-1 filing timeline is also worthwhile if you plan to hold the fund in a taxable account, so you know what to expect come tax season.
