Takeaway
StoneX analyst Bruno Santos argues diesel is the squeeze point of the current refining crisis: roughly 14% of global refining capacity was offline in September — about double the ~7% seasonal norm — and the regions hit hardest, Russia and the Gulf, are predominantly middle distillate exporters. With US refiners already running flat out, the heating oil crack over Brent above $100/bbl for the first time ever, and US diesel stocks below the five-year average, the presenter sees tightness persisting — the DOE reportedly expects US diesel inventories under the five-year minimum for much of 2027.
What the presenter said
- ~14% of global refining capacity was offline in September versus roughly 7% normally seen at this time of year; unplanned outages accounted for about 50% of the total offline capacity [00:24, 00:38]
- Russia is the biggest contributor to unplanned outages — Ukrainian attacks took more than half of the country's processing capacity offline [00:42]
- Moscow has banned diesel exports; per the presenter, the ban runs until at least the end of October, with an extension into early 2027 already approved [00:52]
- Saudi Arabia and Kuwait experienced unplanned shutdowns following Iranian and Houthi attacks [01:10]
- Asia added scheduled maintenance: China had more than 3 million b/d offline and has suspended product exports this month to rebuild its own stocks [01:25, 01:35]
- Because Russia and the Gulf export mainly middle distillates, diesel has borne the brunt of the supply loss [01:43]
- US refiners are maximising middle distillate output on exceptional margins [02:21]; the heating oil crack spread over Brent went above $100 a barrel for the first time ever [02:31]
- Heavy exports drained US diesel stocks — September inventories at ~108 million barrels versus a ~120 million-barrel five-year average [02:38] — and the DOE expects them to stay below the five-year minimum for much of 2027 [02:53]
- On US export-ban talk: the White House denied preparing a 90-day diesel export ban, and the presenter sees the focus on voluntary restraint and measures such as expanding biodiesel sales rather than a government-imposed ban [03:13]
Trade ideas
None stated — no actionable trade was put forward in the video. The market view instead: an exceptionally tight middle distillate complex, driven by outages concentrated in key exporting regions, record distillate cracks, and US inventories already below the five-year average with a DOE-projected stock deficit into 2027. The horizon discussed is medium term, and the overall tone is mixed rather than a one-way directional call.

Risks and what would invalidate this
Risks named in the video (framed as factors sustaining the squeeze): - Continued Ukrainian attacks on Russian refineries - Continued Iranian and Houthi attacks on Middle Eastern refineries, plus uncertainty over the stability of refinery production in the region - A prolonged Russian ban on diesel exports - US diesel inventories remaining below the five-year minimum for an extended period
No price-based invalidation levels were given — with no trade proposed, the presenter offered no stop or reversal criteria.
