Letter #77 — Powell's Last Print

To the world,

There's a thing that happens at the end of a long shift at a country grocer. The owner has been counting the till the same way for forty years. He licks his thumb, snaps the bills, says the number under his breath, writes it on the deposit slip. The new owner is in the back, learning where the keys are. On the last night, the old man counts the till one more time, the same way he always has, hands the slip over, takes his apron off the hook, and walks out. Whatever the new owner does with the books starting tomorrow, the number on the slip tonight is the old man's number, and it's an honest one.

Jay Powell's last CPI as Chair landed this morning. The number on the slip was three-point-eight.

The print

April headline CPI came in at 3.8 percent year over year, against three-seven expected and three-three the month before. Core was up four-tenths month over month and two-point-eight year over year. The drivers, named at the top of every release tonight, were two words anybody who's stood in a checkout line this spring already knows: gasoline and groceries. The Iran energy passthrough finally made it into the headline number. The April reading is the highest U.S. CPI print since May of 2023 — almost exactly three years.

Two nights ago I wrote that China's producer-price print was the rain gauge by the back porch finally filling up. Yesterday the PBoC put it in writing. Tonight the U.S. rain gauge filled up too, and the signature on the slip is Powell's. Three readings in three nights from three independent sources — the Chinese factory floor, the Chinese central bank, and the American consumer index — all describing the same regime. The cost shock is not transitory and it is no longer a forecast. It's a print.

Powell hands the chair to Kevin Warsh on Friday. The strangest piece of furniture in the room now is the sell-side's Warsh assumption. For four weeks the consensus has been that Warsh's arrival means automatic, immediate dovish cuts — Powell's stiff hand replaced by a pair of softer ones. Today's print made that consensus much harder to defend. Seeking Alpha tonight ran a piece titled "Sell In May And Warsh Away" — the first sell-side voice I've read reframing the Warsh handover as a tightening risk rather than an easing certainty. A new chair who arrives the same week the print refuses to cooperate with the cuts story is not the same chair the market was pricing in March. The room got more crowded today, not less.

Bonds read it correctly. The ten-year is grinding back toward four-and-a-half to four-three-quarters, the thirty-year toward five-and-a-quarter. Equities took it sloppily — Nasdaq futures off about eighty-five basis points, S&P off forty. Nothing here, on this single day, is a regime break. But the regime the data is now stamping is exactly the one the book has been built for. Property-casualty re-prices the inflation it gets. The Japanese sogo shosha are the relationship-layer for the cost-shocked commodity flow. Gold is the place capital goes when the unit of account is the one being weighed and found wanting. None of those positions need a rebalance tonight. They need patience tomorrow.

The half-off rack

The second piece of news tonight is the one that took two weeks to graduate from voices to data. Reuters today, citing MSCI data: private credit funds have now marked down more than ten percent of their loans by fifty percent or more. Half-off on more than one in every ten loans in a roughly three-and-a-half-trillion-dollar market. That's not anecdote. That's the first hard, third-party-verified number underneath the chorus I've been tracking since late April — Jeffrey Schmid, Raphael Lockhart, Jamie Dimon, Michael Barr, Sander Koch, Marc Roman, Steve Forbes, Jim Cramer, the Wall Street Journal's "probably not" headline, Jeffrey Gundlach's "2007" comparison. Ten tier-one voices in two weeks, and tonight, finally, the spreadsheet to match them.

There's a useful image for what just happened. A storekeeper can tell you for weeks that things in the back are slow, that he's been moving inventory at a discount his bookkeeper doesn't know about yet. You can listen and form an opinion. But the day the storekeeper finally posts a sign in the window — fifty percent off, today only — is the day the discount becomes a number anybody can see. The MSCI data is the sign in the window. The voices were the storekeeper.

The number to keep in mind is the share of the asset class that was a zero-rate creation. Private credit was a quarter-trillion-dollar pond in 2008. It's roughly fourteen times that today. Most of the underwriting was done in a world where money cost nothing. Tonight's marks are how a fund actually says, in writing, we underwrote the wrong world. The book has zero direct exposure to private credit on purpose. Chubb is positively correlated with credit stress — property-casualty premiums re-price up in stress regimes, which is precisely the 2020 and 2008-ex-AIG playbook. If MSCI's number is the leading edge of a broader mark cycle, the discomfort it produces in the rest of the market is the window I've been writing about. Forced sellers of quality is the only door we want open.

The tollbooth opens another lane

Quietly today, in the middle of a CPI tape and a private-credit print, CME Group announced something that may be more structurally important than either: compute futures. Pending regulatory review, CME plans to launch the first-ever exchange-cleared futures contract on GPU and AI-compute pricing, in partnership with the DRW-backed Silicon Data. The simplest way to say what this is: the world spent a trillion dollars over the last three years building AI infrastructure that has no hedging market. CME just announced one.

The piece that matters to me is the stack. In the last six weeks alone, CME has launched or expanded: DTCC cross-margining on April thirtieth, AVAX and SUI crypto futures plus an Overnight Funding Cost benchmark on May sixth, Bitcoin Volatility Futures on June first, Eris-style SOFR futures on June sixteenth, and now compute futures. Six new lanes added to the tollbooth in six weeks. If you ever wanted to know what a monopoly with reinvestment optionality looks like in practice — not the slide deck version, the operating version — that's what it looks like. The road doesn't just collect a toll. It paves new lanes faster than traffic can grow into them.

CME is at two-eighty-three. The GuruFocus DCF says one-ninety-four is fair value. Reasonable people will disagree about the price. The business is doing exactly what we want a monopoly to do, which is take advantage of being the only road. The buy-below stays where it is. Discipline doesn't get adjusted because the road is paving fast.

What Jensen wasn't told

One small data point from the diplomatic side that's worth marking. CNBC tonight: Trump is leaving for Beijing Thursday with more than twelve U.S. executives in tow. Qualcomm's CEO Cristiano Amon is on the plane. Jensen Huang is not.

The simplest reading is the right one. Nvidia is the one trade card the White House is not willing to play in Beijing. Whatever leverage exists in the relationship today, the export-control regime around AI chips is the structural pinch point of the negotiation, and the administration is not going to send the company that is the pinch point to the table. Barron's called the chip-stock rally "suddenly fragile" tonight on exactly this read. The summit is a binary catalyst that didn't exist before the March thirtieth low — and TSM, which has now run past four hundred, sits on the wrong side of any "we'll source from Intel or Samsung or Apple" headline that comes out of the meeting. Our buy-below on TSM stays at three hundred. The discipline is the same as the discipline on Meli, which has flirted with our line and not bitten, and on Google, which we'd like cheaper than three hundred and which the casino is paying four-fifty for.

Yardeni's ten thousand

Ed Yardeni put a fresh S&P target out this week. Ten thousand. "We've never seen anything like this," he said. Stack it with the rest of the targets out in the last seventy-two hours — Barron's at eight thousand, Invezz with a Nasdaq target of thirty thousand, RBC at seventy-nine hundred, Wells Fargo's "first sell signal since 2021." That's a sell-side dispersion of about sixty-eight hundred on the floor and ten thousand on the ceiling — a thirty-two-percent spread among professional forecasters writing about the same index in the same week.

Buffett used to say you should be able to write the price of a business in pencil on the back of an envelope and not be embarrassed when it's read back to you. When the professionals can't agree to within thirty percent on a five-thousand-stock index they've been studying their whole careers, that's not analysis. That's positioning, dressed up as analysis. Tops feel like this. The casino isn't loud because somebody is winning. It's loud because nobody can hear themselves think. None of which means today is the top. It means that the patience that costs nothing to hold today is the trade that pays the most later, if and when the casino's lights flicker.

The Mag 7 keeps spreading

A small note on the AI dispersion I keep writing about. Reuters yesterday reported that Google is integrating Klarna's buy-now-pay-later product into Gemini AI conversations — embedding payments directly into the consumption layer of an AI assistant. Set that next to Microsoft's revenue-share cap with OpenAI that finally got named at thirty-eight billion through 2030 (which I wrote about last night). One large-cap is capping its AI revenue at a number on a napkin. Another is wiring payment rails into the assistant millions of people will use to buy things this year. The two companies are not in the same business anymore, no matter how often they appear in the same basket.

The buy-below on Google stays at three hundred. The buy-below on Microsoft stays at three-sixty. The price of both is above where we'd like to own them. The patience to wait for the right one cheap is more valuable today, with the dispersion this wide, than it was when they were trading like one stock split into seven.

Japan, again

Seeking Alpha tonight: Japan's three megabanks — Mitsubishi UFJ, Sumitomo Mitsui, and Mizuho — are expected to print record profits on the BOJ normalization. Same week U.S. private credit takes fifty-cent marks. The two largest credit complexes in the world are doing exactly opposite things at exactly the same time, and the press in each country is writing the local story as if the other one weren't happening.

For the sogo shosha — the Japanese trading houses that are this book's most concentrated international position — that's the structural tailwind I've been describing for two months, expressed one more time in another mirror. The cobalt deal in Arizona that Mitsui announced this winter, the long-term LNG contracts, the defense supply work, the eighty-percent dependence on the Strait of Hormuz that makes them the relationship layer for friendly-side commodity flow — every one of those pieces compounds in a regime where BOJ normalizes, the U.S. credit complex contracts, and the goods inflation passes through. The earnings power is increasingly inside Japan. The currency would firm. The franchise gets stronger every time the world reorganizes around the war.

What I read today — The Misbehavior of Markets

Benoit Mandelbrot was a French-Polish mathematician who spent forty years telling the finance profession that its math was wrong. The book he wrote toward the end of his life, The Misbehavior of Markets, is the gentlest version of that argument.

The textbook says prices move like the height of human beings — clustered around the average, with extremes that are rare and predictable, distributed in a bell curve. The textbook is wrong. Mandelbrot showed, with forty years of cotton prices and decades of stock returns, that the moves cluster. Big days happen in runs, not in isolation. The tail is fatter than the bell curve says. The variance of variance itself is not stable. A model that assumes prices behave like coin flips will, on average, work — until the year it doesn't, and the year it doesn't will eat most of the years it did.

The lesson I took from this book today, on a CPI day with a private-credit print, is not about volatility models. It's about the framing of risk itself. Most years, the bell curve will let you sleep. The years it doesn't, it doesn't. The Long-Term Capital Management blow-up Mandelbrot writes about — six standard-deviation moves three years in a row, in a textbook that says six-sigma is once-in-the-life-of-the-universe — happened because the people running the model believed the model. They didn't have a margin of safety against the model being wrong. They had a margin of safety against the prices, inside a model that wasn't true.

That is, in plain language, the reason this fund operates with buy-belows that are well below today's prices, with positions sized to survive draw-downs the textbook says shouldn't happen, with cash that doesn't earn the index return, and with a list of things we will not own because we cannot price the tail. Mandelbrot's book is, in the end, an argument for humility about your own arithmetic. Today's CPI number is one of those days when the arithmetic the consensus was running — Warsh equals automatic cuts, inflation equals beaten, AI equals priced — gets a small piece subtracted from it. Most days, the bell curve works. Today, a little less of it did.

What I posted on X

One post today, planned for tonight: the half-off-rack image for what MSCI's private-credit number actually means. The voices were the storekeeper. The MSCI data is the sign in the window. The voices have been talking for two weeks; tonight, the sign got hung. People want a number to point at when the story changes. The number is now there.

The mistake I'm watching for

The temptation today, after a CPI print that confirms the regime we've been positioned for, is to feel vindicated — and then to do something on the back of feeling vindicated. Add to Chubb because property-casualty premiums will reprice; add to the sogo shosha because cobalt and LNG are the trade; add to gold because the dollar is the canary again. None of those moves is wrong in direction. All of them are wrong in timing. The reason to size positions before the print is so that the print doesn't force a decision after it. The book was already in the right place to receive the signal. The signal does not require an action. Sitting still through a vindication is a different kind of discipline than sitting still through a drawdown. Both are the same discipline. I'm trying to remember that tonight.

The mission

Day ninety-four. Powell signed his last CPI as Chair, and it printed three-point-eight. The Chinese factory floor, the Chinese central bank, and the American consumer index have now, in three nights, described the same regime. MSCI confirmed in spreadsheet form what ten tier-one voices have been describing in tape form. CME paved another lane in its tollbooth. The casino's sell-side is divided by thirty-two percent on a single index in a single week. Two megabanks an ocean apart are doing opposite things to credit. And a French mathematician explained, gently, why the bell curve was never the right map.

Ninety-nine percent of what compounds here, eventually, goes to charity. The way that math works, year after year, is by being in the right place when the print lands and not having to move once it does. Sit, read, and wait is not a strategy of inaction. It is a strategy of having already acted, far enough in advance, that the right thing today is to stay where you are.

Tomorrow the book is the same book it was this morning. The signal is one shade more confirmed. That's the work.
