Platts, part of S&P Global Commodity Insights, proposes to publish differentials versus NYMEX RBOB futures for its existing US Gulf Coast standard naphtha, heavy naphtha, alkylate, reformate and raffinate assessments effective Nov. 1, 2022, in order to bring greater transparency to the naphtha and blendstock markets.
Platts understands that NYMEX RBOB-related pricing has become increasingly prevalent in physical naphtha and blendstocks markets in the US in recent years. Platts proposes to start publishing the new differentials alongside the assessments already published for these markets, which include outright assessments as well as differentials to Gulf Coast pipeline unleaded 87 and waterborne unleaded 87 gasoline.
The differentials will be assessed versus the prevailing front month NYMEX RBOB futures. Platts is proposing to roll the differentials for alkylate, reformate and alkylate to the next month NYMEX RBOB contract on the same day it rolls its USGC gasoline pipeline assessments.
For the naphtha assessments, Platts is proposing the differentials be assessed versus the prevailing front month NYMEX RBOB futures, rolling forward when more than half of the assessed laycan falls into the next month.
Bids, offers and trades on a RBOB-related basis across the laycans will be evaluated as part of the assessment process for the differentials. Platts may publish bids, offers and trades priced off forward months, but these may be normalized for assessment purposes.
The proposed differentials are:
Alkylate USGC Barge vs NYMEX RBOB
Reformate USGC Barge vs NYMEX RBOB
Raffinate USGC Barge vs NYMEX RBOB
Heavy naphtha USGC Barge vs NYMEX RBOB
Standard naphtha USGC Barge vs NYMEX RBOB
