The Second Mouse Is About to Get the Cheese

Oil plus the Macro Soft Patch — after going through "400+ charts," two actionable reads: a stagflationary soft patch (diesel above $6 at all-time highs, ISM services prices paid saying CPI "is about to pop," OBBBA stimulus rolling off, housing supply from 80-year-old Boomers not clearing at 7% mortgages) with a split Fed that will not hike into the midterms despite 88% odds priced — "makes me want to receive the 2Y and SOFR"; and in oil, ETF plumbing that says the crowd is fading the rallyBNO up 50%+ with shares outstanding falling and short interest at all-time highs (>20% of shares), borrow turning "provocative," retail still piling into SCO — so "I think oil is about to scream higher and am worried I don't own enough."

One-line take: a return-from-travel chart sweep that reprises his Jul-24 "The Second Mouse Gets the Cheese" oil call with a new layer of evidence — ETF creation/redemption mechanics. Macro: "ISM Services Prices Paid is telling us CPI is about to pop," and "the diesel national average just broke above $6 to all time highs. Diesel touches everything." Stagflation returns "with a vengeance" through a soft patch (OBBBA stimulus rolling off, housing "springing a leak" at 7% mortgages, Boomer housing stock "not clearing"), maybe "just enough Soft Patch to engineer a brief Growth Scare" — though leading jobs data says it "may not stick for long." Fed: "I have no idea," but with a split committee two months before the midterms, "do you really think Warsh is going to pick a fight with Trump by hiking?" — so "it actually makes me want to receive the 2Y and SOFR here, and also makes me uncomfortable in the long bond position": with 88% of a hike priced, "we could very well see a giant stop-out of flattener trades and the long end is going to feel it" (his bond calls "will join so many other options trades in heaven"). Oil: the "CTAs max long / beware TACO" worry is "no longer" his — managed money is far less stretched than earlier this year "~$20/bbl from new highs." The novel evidence is BNO: price +50% while AUM is only ~20% above the July lows, shares outstanding falling (11.8→10.1mm in two weeks) and short interest at an all-time high ~2.2mm shares, over 20% of shares outstanding — "rising price, rising short interest, shrinking share count — is the mechanical signature of 'the market is fading this rally'," a squeeze setup with borrow rates "starting to look…provocative." Retail's SCO (2× inverse WTI) keeps taking inflows at fresh lows and is still ~50% bigger than BNO. Vols show "no fear" of an upside skid despite Bab-el-Mandeb and six months of storage depletion; managed money % of OI has room to 2017-18 levels while Brent OI is down ~25%; respected oil traders he knows have "lightened up significantly." Verdict: "The sentiment and positioning is wrong here… I think oil is about to scream higher and am worried I don't own enough, and I'd like to think I'm pretty long."

Row-scope note. The macro half names no securities — ISM services prices paid, diesel, OBBBA, housing, jobs/PMI, the 2Y, SOFR and the long bond are not tabled (hub convention: rates and commodities get no row unless he names a vehicle). He says he wants to "receive the 2Y and SOFR" and is "uncomfortable in the long bond position" (his bond calls), but gives no instrument, so there is no rates row. In oil, WTI and Brent futures/options are his real book but are not tickers; BNO is tabled because the whole argument runs through its share count, short interest and borrow, and it is his named calls vehicle (Jul-24). ARKK is an explanatory analogy (Neutral). Apollo's Torsten Slok (quoted via Fortune) and Claude (the AI he sanity-checked the BNO mechanics with) are cited, not tabled.

2. Talking points

The chart sweep — "400+ charts" after late-summer travel

Inflation — CPI "about to pop," diesel above $6

The soft patch — stimulus roll-off plus a housing leak

Housing supply — the Boomers hold the cards

Growth — a soft patch that may not stick, but a Growth Scare window

The Fed — a split committee will not let Warsh hike before the midterms

Rates positioning — receive the front end, worry about the long end

Oil — the "CTAs max long" worry is no longer his

BNO flows — price +50%, AUM barely up, shares outstanding falling

The ARKK lesson — how ETF creations feed short sellers

The BNO glitch — falling share count and record short interest

The squeeze case — less creation capacity as a release valve

SCO — retail still selling oil through the broken product

Vol — no fear of an upside skid

Futures positioning — room to 2017-18, and a shrunken open interest

Anecdote and verdict — "worried I don't own enough"

3. In plain English

BNO — United States Brent Oil Fund Positive

BNO is a fund that tracks the price of Brent crude oil by holding near-dated oil futures. Paulo has used options on it as his main oil bet for months, and this post argues the setup has become unusually explosive.

The key is how ETFs work. When lots of people want to bet against a fund, dealers can manufacture new fund shares and lend them out to short sellers — that is what happened to ARKK in 2022. With BNO the opposite is happening: the price is up more than 50%, yet the number of shares in existence is shrinking (big holders cashing out) while the number of shares borrowed and sold short has hit a record, over a fifth of the whole fund. In other words, a lot of people are betting the oil rally fails, and they are doing it in a vehicle that is getting smaller.

If oil keeps rising, those short sellers must buy shares back — from a shrinking pool — and the cost of borrowing the shares is already climbing ("provocative"). That is the recipe for a short squeeze, where forced buying pushes the price up faster. Combine that with speculators in the futures market being far less crowded than earlier in the year, options markets pricing little risk of a jump, and storage cushions worn down, and he concludes oil is "about to scream higher." He is already "pretty long" and worried he doesn't own enough. Not financial advice, as he says.

SCO — ProShares UltraShort Bloomberg Crude Oil Negative

SCO is a fund designed to go up twice as much as oil goes down, day by day. Over longer periods it bleeds: rolling its futures costs money and daily re-leveraging erodes value when prices swing — which is why Paulo calls it a "broken retail product."

He is not recommending it; he is using it as a crowd gauge. Money keeps flowing into SCO even as it hits new lows, and the fund is still about 50% bigger than BNO. That tells him small investors and fast money are betting against the oil rally — the "consensus view" he wants to be on the other side of.
