16 Candles - Revisiting the Argus Sour Crude Index’s Role in U.S. Crude Pricing, Refining
Update: 2025-10-02
Description
In the early 2000s, prices for West Texas Intermediate (WTI) were becoming increasingly disconnected from global fundamentals. WTI reflected conditions in the Midcontinent at the Cushing, OK, crude oil storage hub, where bottlenecks repeatedly distorted its value. In today’s RBN blog, we look at how the problem contributed to the creation of the Argus Sour Crude Index (ASCI) 16 years ago, how the index has evolved and whether it remains relevant today.
