Title: Follow-up to Oil & Retail from earlier — Three Quick Points Show: Paulo Macro (Substack) — paid Guest: Paulo Macro ("Cloudbear") Date: 2026-APR-21 URL: https://paulomacro.substack.com/p/follow-up-to-oil-and-retail-from Length: written post (no timestamps) Note: Back-filled post (processed 2026-JUL-07). Same-day follow-up to "Oil & Retail" (folder 2026-apr-21-followup, like the hub's 2026-jun-04-gold same-day precedent). Three points: (1) an erratum (4mmbpd x $150 = $600mn, not $750mn — point holds); (2) UCO — the 2x LEVERED LONG oil ETF (opposite of SCO) — has seen assets fall ~half to $440mn (less than half the size of the 2x short SCO), costs 8.3% to short with only 200k shares available; and both SCO and UCO are inherently short-gamma products whose inflows exacerbate the daily move into the 2:30pm NYMEX settlement (a timing mismatch vs the 4pm NAV) — likely the "someone banging the close" (rhymes with "Shmessent") that subscribers noticed. Because these funds hold not just the front month but Dec26/Jun27, their footprint on an increasingly illiquid back-of-the-strip is outsized — "why shale is not producing more: they can't hedge farther out because a giant short ETF is sitting on the curve." (3) Molecules vs paper: on the WTI May26 (K26) last trading day only ~7.5k contracts traded vs 33k on the prior (J26) expiry against similar open interest — a thin, potentially unstable expiry echoing the Henry Hub Feb2022 (NGG22) last-day tell that preceded a wild move. "If it prints there, it trades there… probably nothing but vibes." Body reproduced for personal study; Substack chrome removed, wording otherwise verbatim.
Three quick points of follow-up:
First, an erratum — I was tired when I wrote the note, in the part about Saudi exporting 4mmbpd at $150 vs 7mmbpd at $80, 4 x $150 = $600mn not $750mn obviously. Point still holds — not a hard decision.
Secondly, I completely forgot to look at UCO — the opposite of SCO, i.e. the 2x levered long oil ETF. This is stunning:
The assets in the fund have fallen by nearly half to $440mn, which makes it less than half the size of the 2x Short Oil fund… and look at the flows! And if you want to short this, it costs you 8.3% right now with only 200k shares available.
Another thought — many subscribers have noticed in recent weeks that the oil price suddenly sells off right at the NYMEX 2:30pm daily settlement. The speculation among some was maybe "someone" (rhymes with "Shmessent") was banging the close. But now we know there is an outsized shooter on the field:
The SCO (and UCO) are inherently short gamma products, so as we approach settlement each day, inflows exacerbate moves, compounded by the mismatch in timing between the 2:30pm NYMEX crude settlement and the 4:00pm NAV calculation — not unlike 2x or 3x levered single stock ETFs affecting the 4pm close in equities, except in that case there is no timing mismatch.
Also keep in mind that over the past decade the longer-dated contracts in crude oil have grown increasingly illiquid as commercial entities like airlines and shale producers stopped hedging fuel or production farther out the strip. These funds are long or short not just the front month contract but also Dec26 and June27. As a % of open interest, their footprint is outsized. So now we know why shale is not producing more — they can't hedge farther out the strip because someone — a giant short ETF — is sitting on the curve.
Finally, recall molecules vs. paper. Today is the last day of trading for WTI May26 contract (K26). The roll to June26 happened over a week ago. Going into today, there was 20k of open interest still outstanding in K26 as of last night. That may sound high, but for context the open interest on the night before the last day of trading for the April contract (J26) last month stood at 18.5k. The difference is that on the last day of trading for J26 last month, volume was 33k, giving late longs an opportunity to get flat before trading expired. Today so far we have seen 7.5k contracts traded!
I'm not saying crude is about to do something crazy in the next few hours, but I remember seeing something very similar in the Henry Hub natgas Feb2022 contract on the last day of trading while nobody was paying attention because the active NG had already rolled to the March22 (NGH22) contract. This is what Feb22 did on the last day:
…and this is what NGG22 looked like intraday on the last day of trading:
Now look at the expiring CLK26 contract intraday:
That NGG22 last day was a big "tell" for me that Henry Hub was about to do something crazy and all was not right under the covers. Henry Hub ended up doing this over the next several weeks:
Remember: if it prints there, it trades there.
Probably nothing… but still… vibes.
Stay. Frosty.
