Domestic Sweet Blend

Stream Description

Domestic Sweet Crude Oil is the CME (NYMEX) benchmark conventionally produced light sweet crude offered for contract sale at Cushing, OK.

Domestic Sweet is a fully blended aggregate of many feeder streams and only begins its existence in blend tanks in Cushing, OK. It is often confusingly referenced on crude price reports as West Texas Intermediate (WTI), which in fact is one of the feeder streams to Domestic Sweet Crude Oil.

Contract quality requirements are listed in the NYMEX Rulebook Section 200.
