Summary

USO, WTI and Brent are related to crude oil, but they are not interchangeable.

WTI and Brent are major crude-oil benchmarks.

USO is an exchange-traded commodity pool that primarily uses WTI-related futures to create oil-price exposure.

A simplified comparison is:

Feature	USO	WTI	Brent
Type	Exchange-traded commodity product	Crude-oil benchmark	Crude-oil benchmark
Listed security	Yes	No	No
Futures market	USO invests in futures	NYMEX WTI futures	Brent futures
Main reference region	U.S. product	U.S./Cushing	Global/Atlantic basin
Physical crude itself	No	Benchmark represents crude	Benchmark represents crude
Futures roll	Important to USO	Individual contracts expire	Individual contracts expire

Understanding these distinctions is essential before using USO or tokenized OIL(USOON) to express an oil-market view.

What Is WTI?

WTI stands for West Texas Intermediate.

CME describes WTI as a key global light-sweet crude benchmark with the futures contract physically deliverable at Cushing, Oklahoma.

WTI historically plays a particularly important role in:

U.S. crude pricing;
shale production;
refinery economics;
hedging.

What Is Brent?

Brent is another major global crude benchmark.

CME describes Brent and WTI as two of the key global oil benchmarks. Brent is associated historically with North Sea crude pricing and remains especially important in Europe, Africa and international seaborne oil markets.

The modern Brent benchmark basket has evolved over time and now incorporates WTI Midland into the broader assessment process.

Why Are WTI and Brent Prices Different?

Their prices can differ because of:

Regional supply;
transportation;
storage;
crude quality;
export capacity;
refinery demand;
geopolitical conditions.

Both are light sweet crudes, but they reflect different physical and trading ecosystems.

What Is USO?

USO is not another crude benchmark.

It is an exchange-traded security/commodity pool.

USO primarily uses futures associated with light sweet crude delivered to Cushing to pursue its daily investment objective.

USO vs WTI

The biggest difference is:

WTI is an oil benchmark. USO is an investment product.

WTI might trade at $85 per barrel.

USO might trade at an entirely different dollar price per share.

There is no reason those two numerical values should match.

Does USO Track WTI?

It seeks daily exposure related to WTI, but the method matters.

USO uses futures.

Therefore:

WTI spot

and

USO return

can diverge because of:

Futures basis;
Contango;
Backwardation;
Roll schedule;
collateral interest;
expenses.

USO vs Brent

USO is primarily tied to WTI-related futures rather than Brent.

A trader specifically seeking Brent-related exchange-traded exposure would be examining a different benchmark/product structure.

USCF, for example, operates BNO, whose benchmark uses near-month Brent crude futures traded on ICE Futures.

Why Does the WTI-Brent Spread Matter?

The difference between WTI and Brent can signal changes in:

U.S. supply;
international supply;
export economics;
transportation;
regional disruptions.

A widening Brent premium does not automatically mean USO should move exactly like Brent because USO's benchmark is WTI-related.

How Hormuz Can Affect WTI and Brent Differently

The Strait of Hormuz is particularly important to Middle Eastern seaborne crude flows.

Before the 2026 conflict, about 21.6 million barrels per day of oil moved through the strait in Q4 2025; EIA estimated only about 4.9 million b/d in Q2 2026.

Such disruptions can create intense pressure on international crude pricing, shipping and regional spreads.

Because Brent is an important global seaborne benchmark, its reaction can differ from WTI.
