USO vs USL vs BNO: Comparing Three Major Oil Exchange-Traded Products
Summary
USO, USL and BNO are all exchange-traded oil products managed by United States Commodity Funds, but they use different futures strategies.
The key distinction is:
USO
= short-dated WTI-focused exposure
USL
= diversified exposure across 12 consecutive WTI futures months
BNO
= short-dated Brent-focused exposure
That means investors can hold three products that all appear to be “oil funds” and still receive meaningfully different results.
USO vs USL vs BNO at a Glance
| Feature | USO | USL | BNO |
|---|---|---|---|
| Full name | United States Oil Fund | United States 12 Month Oil Fund | United States Brent Oil Fund |
| Benchmark | WTI | WTI | Brent |
| Futures structure | Short-dated | 12 consecutive months | Short-dated |
| Exchange | NYSE Arca | NYSE Arca | NYSE Arca |
| Main curve sensitivity | Front of WTI curve | Spread across curve | Front of Brent curve |
| Commodity pool | Yes | Yes | Yes |
How Does USO Work?
USO primarily references the near-month WTI contract and changes into the next-month contract during its five-day roll process.
That provides relatively concentrated exposure to the front of the WTI futures curve.
How Does USL Work?
The United States 12 Month Oil Fund (USL) uses a substantially different benchmark.
USCF says its benchmark consists of:
- Near-month WTI futures;
- Plus the following 11 monthly contracts.
That produces 12 consecutive futures contracts, with each contract equally weighted when calculating the benchmark's daily movement.
Why Can USL Behave Differently From USO?
Because USL spreads its exposure across the curve.
If severe contango exists mainly at the very front of the curve, USL's broader structure can reduce concentration in that particular roll relationship.
But that does not mean USL is immune to futures-curve risk.
All 12 contracts still move based on oil expectations.
How Does USL Roll?
USCF says USL's benchmark changes by rolling the relevant contract composition on one day each month.
This is another operational difference from USO's new five-day 2026 roll process.
How Does BNO Work?
The United States Brent Oil Fund (BNO) seeks daily exposure related to Brent crude.
USCF states that BNO's Benchmark Futures Contract is the near-month Brent crude contract traded on ICE Futures, moving to the next-month contract when the near month is within two weeks of expiration.
USO vs BNO: WTI vs Brent
This is fundamentally a benchmark choice.
USO
focuses on WTI-related futures.
BNO
focuses on Brent-related futures.
WTI and Brent are both major light-sweet crude benchmarks, but supply, transportation and regional market conditions can cause their prices to diverge.
USO vs USL: Short-Dated vs 12-Month Exposure
Suppose the WTI curve is:
| Month | Price |
|---|---|
| 1 | $70 |
| 2 | $74 |
| 3 | $76 |
| 4–12 | Gradually higher |
USO is concentrated closer to the first part of the curve.
USL spreads benchmark exposure across 12 months.
Their returns therefore can differ substantially even though both are broadly “WTI oil funds.”
Which Product Has More Immediate Oil-Price Sensitivity?
USO's short-dated structure generally makes it more directly exposed to movements at the front of the WTI curve.
USL distributes exposure across a broader set of expectations.
BNO provides a similar short-dated concept but for Brent.
This is a structural comparison, not a prediction that one product will always be more volatile.
Which Is Better in Contango?
There is no guaranteed winner.
A 12-month structure may reduce concentration in an unusually steep front-month roll, but the entire futures curve can also be in contango.
Investors should compare the actual shape of the curve rather than assume:
“USL automatically fixes contango.”
It does not.
Which Is Better in Backwardation?
A short-dated fund such as USO can potentially benefit more directly from strong front-end backwardation.
But actual performance depends on how the curve evolves after purchase.
A favorable curve today can disappear tomorrow.
Which Product Is More Relevant to OIL(USOON)?
USO.
OIL(USOON) is linked to the United States Oil Fund rather than USL or BNO.
Therefore:
USL performance
and
BNO performance
do not directly determine OIL(USOON).
Where RealStocks Fits
MEXC also offers RealStocks, which provides eligible users with access to real U.S.-listed securities through regulated brokerage infrastructure. MEXC states that RealStocks positions represent real shares held in the user's name and can carry associated shareholder entitlements.
Availability of USO, USL or BNO through RealStocks should be checked in the live interface rather than assumed.
Which Oil Product Is “Best”?
There is no universally best oil ETP.
The choice depends on the exposure being sought.
USO
May be more relevant when the goal is short-dated WTI futures exposure.
USL
May be more relevant when the goal is WTI exposure distributed across a broader 12-month curve.
BNO
May be more relevant when the focus is Brent rather than WTI.
FAQ
Are USO and USL the same?
No. USO is more concentrated in short-dated WTI futures, while USL benchmarks 12 consecutive WTI contracts.
Is BNO a WTI fund?
No. It references Brent futures.
Does USL eliminate contango?
No.
Which fund underlies OIL(USOON)?
USO.
Are these physical-oil funds?
No. They primarily use futures and related financial instruments.
Risk Disclaimer
USO, USL and BNO use different futures strategies and can generate materially different results. Historical behavior should not be used as a guarantee of future tracking or returns.
