Note:    Back-filled post (processed 2026-JUL-07). Paulo argues refiner crack spreads (refinery margins) are the ignored "second derivative" that tells you what crude does next. He inverts the Covid-2020 playbook (Charlie Munger: "invert, always invert"): in March-April 2020, a >10mmbpd DEMAND shock saw cracks collapse then bounce back above $10 in the second week of April — the tell that WTI was about to collapse (and go negative on 20 April 2020). Today is the mirror image: a >10mmbpd crude SUPPLY shock, with cracks having peaked near $60/bbl on March 20th and falling for two weeks — the equivalent (but reversed) window, where instead of crude crashing, crude "moons" as demand destruction at the pump feeds back up the chain and forces any upstream product/SPR/barrel to come to market rather than shut in. He warns the "long refinery stocks" trade rhymes with being long tankers into the April-2020 supercontango. Macro/oil framework note — no individual equity tickers named. Body reproduced for personal study; Substack chrome removed, wording otherwise verbatim.

Refiner crack spreads have my complete attention here, and as is typical in the new era of speculation, pretty much nobody is paying attention, and even if they are, the market is missing some key connections.

By now many readers will tire of hearing me compare this crisis to Covid (a rolling shock from East to West), but in reverse. Same >10mmpbd crude loss, but supply shock rather than demand shock. In both cases, refinery cracks are screaming at us about what comes next, but as Charlie Munger taught us: invert, always invert. We are seeing the opposite happen, and the implication seems so obvious it makes me wonder why more people are not playing this forward (and makes me question 2+2=4).

Let's talk about Covid and the lead-up to the day that will live in infamy — 20 April 2020 — when WTI went negative and forced the US shale industry to shut in the world. As we have discussed, "Tom Hanks has Covid" on March 11th finally touched off the avalanche in risk. This was also the day crack spreads collapsed (i.e. refinery margin, shown in white). Notice WTI crude had been dropping all year from ~$60 to $30 on the day we went off the cliff (red line):

Notice how as refinery margins collapsed to ~$5-10/barrel, and then bounced around. Then beginning on April 3rd, cracks started to rise and broke back above $10 in the second week of April. This was the "tell" that crude oil was going to collapse. The worst of the demand destruction had arrived, but because shocks move from the tip of the spear (the pump) back up the chain to the wellhead, the inflection here was the moment you knew that the refinery margin was the "second derivative" that oil was about to do something truly crazy.

Fast forward to today. Again, because this is a 10mmbpd+ crude supply shock (in addition to several million barrels of products), expect the same — but in reverse. Notice where we are:

Cracks peaked near $60/bbl on March 20th and have been falling for two weeks. We are now in the equivalent window (but in reverse) of second week of April 2020, when cracks broke higher and then oil imploded. With cracks falling, we are getting into dangerous territory where crude oil doesn't crash — it moons. Chalk it up to demand destruction at the tip of the spear (rather than stabilization in April 2020 at the pump), feeding back up the chain to the wellhead (in this case forcing any upstream product anywhere — in any form or grade, no matter the owner/SPR/whatever — to come the market rather than shutting in… invert).

It's all in reverse. Only this is bigger — and more persistent — than Covid.

Think about it.

And if you really wanna analogize, I fear the same logic around outsized returns that got investors (including myself) into trouble being long tankers in the supercontango in April 2020? That's the same logic running through the long trade in refinery stocks here.

If this, then that.

Invert. Always invert.

Stay frosty… as always, kindly yours,
