DSW

Cushing has done it again! The all-important hub in central Oklahoma is once more broadening the range of crude oils it handles, this time by figuring out how to receive and blend the quirkiest of domestic oils: yellow wax crude from Utah’s Uinta Basin. Better still, the blending can create a fully compliant Domestic Sweet (DSW), the crude quality deliverable on the CME/NYMEX futures contract usually referenced as West Texas Intermediate (WTI). In today’s RBN blog, we discuss how it works and what it means for Uinta producers, waxy crude marketers, refiners and Cushing itself. 

CME’s NYMEX light sweet crude oil contract in Cushing, OK, is not West Texas Intermediate — WTI. Instead, it is Domestic Sweet — commonly referred to as DSW — with quality specifications that are broader and generally inferior to Midland-sourced WTI. In fact, pristine Midland WTI delivered to Cushing sells at a reasonably healthy premium to DSW. That difference in specs, and the fact that the quality of DSW is considerably more variable than straight-as-an-arrow Midland WTI, makes most purchasers of exported U.S. crude (and many domestic refiners too) strongly prefer the more quality-consistent Midland WTI grade. For that reason, when Platts set out to allow U.S. light crude to be delivered as Brent, it said that only Midland WTI will qualify. Consequently, a marketer cannot take delivery of a NYMEX-quality barrel at Cushing, pipe it down to the Gulf Coast, and deliver it to a dock for export if the ultimate destination of that barrel is to be reflected in the Brent price assessment. The implication? There are now effectively two U.S. crude oil benchmark grades, each of which is valued differently, priced differently and used by different markets. Is this a big deal for the valuation mechanisms for U.S. crude oils, or just a minor quirk in oil-market nomenclature? We’ll explore that question in today’s RBN blog.
