Gasoline: recovery in cracks giving market whiplash as risk priced very much back in

EPA waivers tighten Atlantic basin naphtha further as East prices back up to compensate and keep pulling barrels.

Last week we were focused on asking the question of why the market was so complacent about the imminent shortfall in products supply globally – originating in Asia but ultimately landing globally.

Gasoline cracks and structure were the strong telltale sign that something was awry on pricing, the market clearly happy to let distillates prop up refining margins and pull yields towards diesel and jet.

With the market now (correctly) pricing no quick resolution to the closure of the SoH, however, gasoline markets in the East especially have turned around and are more heavily pulling barrels out of the Atlantic Basin.

We had found what appeared to be a structural limit with E/W at +$10/bbl which had allowed ARA to almost compete into the Pricing Centre in the East. The E/W narrowed strongly on some correction to Sg92 cracks last week, but they have rallied once again now.

However, prompt E/W trading now at +$8/bbl is not the same proposition as it was before thanks to the selloff in gas-nap, raising blend costs in ARA significantly. The move in the paper arb has maintained ARA’s competitive advantage across the East of Suez, but does not make ARA workable into the Singapore Pricing Centre as it was when it was last near these levels.

(April Sg92 spread and E/W)

In the Atlantic Basin, there have been two major developments in recent days. The first is around policy developments in the US, where EPA announcements changing the nationwide RVP standards from May 1st.

Likely in large part linked to the fallout from this announcement, the April TA Arb has gathered steam and net-RVO is now trading in positive territory after having been around -17.50cpg just two weeks prior.

Nothing has changed in the competitive picture across the Atlantic Basin or East of Suez, however, with these paper arbs largely moving to compensate for a huge selloff in prompt gas-nap in Europe.

(RBOB Arbs slammed shut)

The more consequential dimension of the EPA announcement is structural rather than near-term.

Moving to a single national pool at 10psi RVP from May 1st dramatically increases the fungibility between RBOB and CBOB — with CBOB currently running ~17cpg cheaper than the screen — and the blend composition difference is not trivial: CBOB is roughly 40% alkylate and 45% naphtha versus the more reformate-heavy RBOB pool.

The extreme read from at least one physical market contact is that this is the opening move toward cancelling RBOB entirely and making the whole US market CBOB-spec on a permanent basis, which would in theory destroy the RBOB screen and shift the US blending market from a seasonal ARA dynamic to a year-round Eurograde and naphtha market.

(Houston still the cheapest source of supply into the Atlantic Basin)

The more measured view — and arguably the one more widely held in the physical market — is that the near-term production impact will be limited. We can see a reasonable uptick in volume from additional ethanol and butane in the national pool, but expect this is now largely priced in.

There are currently extremely strong incentives to maximise distillate and jet yields (not just in the US), and so we could expect that several refiners may in practice do little with the extra blending latitude, or even reduce finished gasoline output marginally vs a ‘normal’ Q2.

May RBHO Swap is currently say around the -71cpg mark, compared to -20cpg at the beginning of the month and positive territory at this time of year in the last three years.

The piece that feels most underappreciated is the naphtha implication. A meaningful shift toward CBOB specifications raises US naphtha demand sharply at precisely the moment global naphtha supply is already under acute pressure — a policy trade-off that prioritises pump affordability over feedstock availability.

The US simultaneously becomes more self-sufficient in finished gasoline, reorienting its import requirement away from finished grade barrels toward alkylate and Eurograde components, and reducing the pull on ARA reformate in the process.

The response of gas-nap this week suggests that at least European naphtha should also stand to benefit.

(TA Arb and freight)

Layered on top of this is the question of RBOB as a deliverable: millions of forward contracts are written against RBOB specifications, and if physical demand migrates toward CBOB, the screen risks becoming progressively untethered from the market it is supposed to represent — a source of real positioning uncertainty that is unlikely to resolve cleanly through Q2.
