Jet arbs swing open as regrades fall; NWE CIF diff up over $20/mt, but the cap is now in sight
- Last call status: correct. Last week’s commentary and Thursday’s podcast argued the Singapore regrade would need to decline from here to reopen the arbs, with more positivity in European jet pricing in the short term. Both have played out: USGC and Singapore regrades have declined over the past three or four days, extending a move Carrie Ho’s Asia update already captured in the week to 22 July, with the Singapore regrade down $5.19/bbl w/w to -$3.82/bbl.
- August’s NWE jet CIF differential has jumped by over $20/mt over the same period. The events set out by June Goh and Aaron Kildow’s content today are key here: Lloyd’s of London reportedly withdrawing war cover for Saudi-linked vessels, Yanbu barrels facing a forced reroute north up the Red Sea via Sumed or Suezmax transit, and only a handful of tankers now crossing Bab el-Mandeb, with the Suez Canal Authority raising surcharges on top.
- These occurrences have combined with weakening in both the HOGO and the jet and GO e/w spreads to open up pretty much every major jet arb into Europe. Michael Ryan’s TC11 note corroborates the direction of travel: Ulsan jet arbs into Los Angeles are shut across August and September, leaving Europe as the destination pulling Eastern barrels.
- This should be enough to cap further gains in the NWE jet CIF differential in the medium term at least. Though much of it depends on a resolution to the Middle East conflict, which continues to affect exports through the Strait of Hormuz and Bab el-Mandeb.
- The impending end of European peak summer jet demand, at the end of August or start of September, would remove the demand pillar underneath the current differential independently of anything happening on the supply side.

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.
