Light ends stay bid as escalation broadens beyond Hormuz

Deep Dive Summary:

• Houthi forces seized Mocha on Thursday, sitting on the Bab el-Mandeb approach, putting the shorter Western routing East in question.
• A Red Sea closure would force everything onto the Cape and require a wider E/W down the curve to pay for the extra voyage time.
• The E/W has gained on the week to +$66/mt, clearing the level that keeps the arb East open on both Western routings.
• TC5 jumped to +$185/mt, back at record levels, while the MOPJ and NWE spreads both climbed above the $40s.

The week has been one of broad escalation feeding straight into naphtha structure. Houthi forces seized Mocha on Thursday, sitting on the approach to Bab el-Mandeb, the US struck three Iranian tankers in retaliation for an IRGC missile attack on two US Navy warships, Jizan was hit again, and unconfirmed reports of a strike on Saudi Arabia’s East-West Petroline circulated overnight.

Brent was pushing toward $110/bbl yesterday with Hormuz traffic still well below pre-war norm. The complex has priced it accordingly: the E/W added gains on the week to +$66/mt, the MOPJ and NWE spreads climbed above 40’s, and TC5 also jumped +$185/mt. Cracks have lagged the spreads due to crude skyrocketing.

The offsetting development is diplomatic, with Iran saying a Hormuz management deal with Oman is now days away and Gulf foreign ministers due to meet Tehran, though nothing has yet translated into a de-escalation.

The E/W at +$66/mt is now high enough to keep the arb to East open on both Western routings. Skikda economics are workable for October deliveries and the Cape of Good Hope re-routing has opened for November windows, so Western sellers no longer depend solely on Suez to reach.

The threat to that picture is the Red Sea itself. Mocha sits on the Bab el-Mandeb approach, and if the corridor closes the shorter routing East disappears, leaving the Cape as the only option and requiring a wider E/W down the curve to pay for the extra voyage time.

A Red Sea closure would also cut the reverse flow, with Red Sea barrels into NWE having been one of the few Western supply additions in recent weeks, but the bearish risk is limited.

Gasoline continues to give naphtha a firm floor despite EBOB correction. In the EoS, Singapore 92 cracks have hit 10-year highs at $30/bbl for September and $23/bbl for October, despite the diesel-mogas spread doubling to more than $40/bbl. The market is short of both diesel and gasoline, so mogas yields have to compete with diesel for barrels and blending demand stays firmly in the bid.

Pro/Nap East has deepened sharply again to -$73/mt, correcting after a brutal run higher through August as propane gives ground relative to naphtha.

That is happening despite Aramco told regular Asian customers it will not supply propane at all during the first half of 2027 on maintenance, while continuing to offer butane, which removes a structural pillar of Asian propane availability well beyond the current conflict.

For now, the deepening spread reopens the switching incentive for flexible crackers, a mild negative for Asian naphtha demand, but the forward supply picture argues that window does not stay open indefinitely.

Overall, the global light ends complex remains firmly biased to the upside. The E/W has cleared the level that keeps both Western routings open, AG freight is back at record levels, gasoline cracks are at decade highs and the escalation is broadening rather than easing.
