ARA Blenders Squeezed on Components
- Prompt spreads and cracks have strengthened across the gasoline complex, whereas deferred contracts are taking a step lower. EBOB continues to lead gains, with SING92 and RBOB following in this order.
- Prompt TA arbs (summer grades / F1) have quickly retraced following ascendant E5 barge windows despite Wednesday’s reports of PADD 1’s Monroe Trainer FCC outage extending into September, adding further pressure to a region that has an upcoming planned turnaround on the Paulsboro CDU from mid-September through mid-October.
- Extension of the Trainer FCC comes at a point of relative tightness within PADD 1 as New England and Lower Atlantic inventories reportedly built, offsetting declines in Central Atlantic stocks per the week prior’s EIA report.
- Mid-September onwards, winter specification arbs have continued to provide export margins for ARA blenders into PADD 1. Though gasoline arbs from NWE still widely favour deliveries into WAF over NYH from a marginal perspective, with heavy naphtha arbs providing more support than finished F grades.
- As mentioned within this week’s deep dive, the Gas-Nap continues to widen in NWE as components remain challenging to move via the Rhine chokepoints.
- The E5 blender margin has continued to gain within NWE, with prompt E5 margins now up to +$11.25/mt driven largely by the regional sales prices in ARA.
- Underlying blend costs have failed to see gains due to inaccessibility, with heavy reformate prices remaining elevated but flat throughout the week, while C5+ naphtha has continued to decline on the week despite closed arbs into Rotterdam.
- Despite this, naphtha exporters in Rotterdam continue to see stronger margins to send cargoes for export towards Brazil and NYH across August loaders.
- Implying that on-water Rotterdam components are finding homes elsewhere, adding further support to prompt Gas-Nap support.
- Though, this rally remains contingent upon blend margins not superseding export arbs into NYH (an additional +$5/mt at the highest compared to prompt E5 blend margins) and prompt availability of components upon Rhine navigability.

About Sparta
Founded in 2020, Sparta made waves in the commodity analytics space in March 2022 when it secured a $6m series A investment from Singular. This success then later snowballed into a further $17.5 million in a series A funding round led by the technology venture capital firm FirstMark, with participation from existing shareholder, Singular.
The platform, created by former traders Miles Moseley and Felipe Elink Schuurman, is designed to answer a common problem shared by most traders: 90% of pricing data required to make trading decisions is kept in silos and shared manually by voice, email, or chat.
Sparta breaks these existing data silos and combines the physical and paper markets to provide traders with live access to global raw prices, from futures and swaps to forward freight and physical premiums. We work with clients globally, including Philips 66, Chevron, Trafigura, Equinor and more.
