The United States Oil Fund, LP — trading under the ticker USO — is one of the most widely followed exchange-traded products (ETPs) offering exposure to crude oil prices. Unlike a traditional exchange-traded fund (ETF) that owns stocks or bonds, USO is a commodity pool that gains its exposure through futures contracts. It attracts attention from traders, institutional investors, and individual investors who want a convenient, publicly traded way to express a view on the direction of oil without trading futures directly or buying shares of energy companies.
Investment objective. USO seeks to have the daily percentage change in its per-share net asset value (NAV) reflect the daily percentage change in the spot price of light, sweet crude oil delivered to Cushing, Oklahoma. It does this by holding the near-month WTI crude oil futures contract traded on the New York Mercantile Exchange (NYMEX), plus interest earned on its collateral holdings, less fund expenses.
Index and strategy. The fund is passively managed and generally tracks a benchmark associated with front-month light, sweet crude oil. Because futures contracts expire, USO must continually "roll" its positions — selling the expiring contract and buying the next month's contract. Historically, the fund concentrated in the front-month contract; since April 2020 it has used a more laddered approach, holding a mix of front-month and later-expiry contracts to help manage concentration and roll costs.
Issuer and launch. USO was launched on April 10, 2006, and is sponsored and managed by USCF (United States Commodity Funds LLC), a commodity-focused product sponsor based in Houston, Texas. USCF also manages other commodity ETPs, including the United States Natural Gas Fund (UNG) and the United States Brent Oil Fund (BNO).
Portfolio holdings and allocation. USO's portfolio is dominated by near-month WTI crude oil futures contracts, typically representing the largest single position. The remainder of the fund's assets are held in cash and cash equivalents — including U.S. Treasury bills and money-market instruments — that serve as collateral for the futures positions. As a result, the fund's asset allocation is concentrated almost entirely in crude oil futures exposure and short-term fixed-income collateral, rather than equities or traditional sectors.
Expenses and structure. USO reports a net expense ratio of approximately 0.86%. It is not an investment company registered under the Investment Company Act of 1940; instead, it is organized as a limited partnership and registered as a commodity pool. This structure means shareholders typically receive a Schedule K-1, and there are different tax and regulatory considerations compared with a conventional 1940 Act ETF.
USO is followed closely because it offers one of the most direct and accessible routes to crude oil price exposure in an exchange-traded wrapper. Its ETF overview and investment strategy make it useful for hedging, tactical trading, and short-term speculation on energy prices. Investors and analysts monitor the fund as a gauge of sentiment toward global oil supply and demand, particularly around events that affect production, geopolitics, inventories, and OPEC decisions.
For traders, the fund provides liquidity and the ability to take a position without opening a futures account. Its price moves tend to reflect changes in the underlying WTI futures market, giving users a straightforward proxy for near-term oil price direction. The fund's sector exposure is intentionally narrow — essentially 100% crude oil — which can serve as a concentrated energy allocation within a broader, diversified portfolio.
USO carries several risks that investors should understand. The most significant is roll yield: when the futures curve is in contango (longer-dated contracts priced higher than the near month), the fund may lose value each time it rolls its positions, even if the spot oil price is flat. The opposite condition, backwardation (near-month contracts priced higher), can benefit the roll. Over time, this means USO can diverge materially from the spot price of oil, making it generally better suited to short-term trading than long-term holding.
Additional considerations include commodity price volatility, regulatory position limits imposed by exchanges and the Commodity Futures Trading Commission (CFTC), potential tracking error, and the fund's partnership structure and K-1 tax reporting. Because the fund is not covered by the 1940 Act, investors also have different protections than they would with a conventional registered fund. Its expense ratio is higher than many equity ETFs, which compounds the cost of holding the fund over time.

The United States Oil Fund (USO) occupies a distinctive place in the market as one of the best-known vehicles for crude oil price exposure. Its ETF overview and investment strategy — centered on rolling near-month WTI futures contracts — make it a convenient, liquid tool for short-term energy positioning, while its futures-based structure distinguishes it from equity energy funds. Investors considering the fund should weigh its concentration in a single commodity, the effects of contango and backwardation, and its commodity-pool structure before deciding how it might fit within their broader approach.
