I'm increasingly partial to the argument that increases in the fed funds rate will do little to lower inflation, and may be counterproductive.
- AI investment is unlikely to slow because interest rates are slightly higher
- Energy is highly inelastic and rate changes can't alleviate the current supply shock
- Higher rates hurt supply-side solutions in housing, energy, autos, and other capital intensive industries
- Higher borrowing costs raise business operating expenses, some of which is passed along to consumers
- A large percentage of debt is fixed-rate, dampening the feedback loop but hurting new homeowners, small businesses, and investment
- An economy increasingly dominated by services is less sensitive to rate changes
- This century has repeatedly demonstrated how blunt interest rate policy can be, both in stimulating inflation when it's low and suppressing it when it's high

There are many details from the Federal Reserve IG report that didn't make it into our story:
For example, its building renovation includes underground space equivalent to 9 football fields. Underground construction is expensive but there are height limits in DC. (p. 18) 1/x

The latest Orange Book is out @theterminal!
The major macro themes from the latest earning season:
-Tariff refunds juicing earnings (may turn to headwinds next season)
-Half of S&P 500 companies mentioned some form of shortages (we identified those).
-Truck-driver shortages have raised freight rates, which in turn is driving up cost of moving physical goods
-the AI super investment cycle has left almost no parts of the economy untouched.
-US is going through a manufacturing boom.

I have a very-out-of-consensus view: The Federal Reserve is unlikely to raise interest rates this week.
My baseline:
1. As demonstrated in the July Federal Open Market Committee (FOMC) meeting, the center of gravity of the committee was to hold, not to hike.
2. Several FOMC members seem to share the view of Governor Barr, who said: “At the September FOMC meeting, if trends in the data give me some confidence that inflation is moderating on a path to two percent, then I think we can take a bit more time to assess our policy stance. However, if inflation appears not to be moderating sufficiently, then I think we should act decisively to raise rates.”
So the question is whether the August CPI report moved the center of gravity of the FOMC from holding to hiking.
It is certainly possible that it did, and I wouldn’t be shocked if the Fed does raise rates this week. But my expectation is that the Fed will hold.
Five points:
1. A HIKING CYCLE IS DIFFERENT THAN A ONE-AND-DONE HIKE
The Fed rarely does one-and-done hikes. So the right question is not, “Should the Fed raise rates next week?” Instead, the right questions are: “Should the Fed begin a hiking cycle next week?” and/or “Should the Fed do a one-and-done hike, which the Chairman will have to explain as a one-and-done hike?”
Viewed this way, the odds of a hike next week should be a lot lower than the 87 percent current priced in by the bond market.
The August CPI report might have been enough to move some FOMC members from favoring holding to favoring a one-and-done hike. But the August report would have had to have done a lot more work to move the center of gravity from holding to a *hiking cycle*. (More on the August CPI report below.)
Moreover, a one-and-done hike is unlikely due to Chairman Warsh’s approach to communications, which suggests that he would not be eager to explain why the Fed did its first one-and-done hike in decades.
I very well might be wrong. It is worth noting that Governor Waller, who is very influential with other committee members, might have signaled support for a one-and-done hike when he said the following on September 3rd: “If there is evidence that progress toward two percent inflation reversed in August, a small adjustment in our stance would help ensure that it resumes.”
2. NOT ROCKING THE MARKET IS A REAL CONCERN
Not rocking the market by holding is an argument that many analysts take seriously. If the Fed does hike, then the desire to avoid the market reaction that would follow from holding could be the decisive factor behind the hike.
* But the bond market thinks there’s a 75 percent chance of two or more hikes in 2026. So a one-and-done hike would still go against the overwhelming consensus of the market, and a one-and-done hike would still find the Fed rocking the market by going against its pricing.
* If Chairman Warsh is looking for an opportunity to signal to the market that the Warsh Fed is different than its recent predecessors, then this is that opportunity.
3. WAS THE AUGUST CPI REPORT THAT TROUBLING?
* Based on the August CPI, I'm expecting August monthly core PCE inflation to have accelerated a bit relative to the June and July. But even so, I expect August monthly core PCE inflation to be around 3.1 percent annualized. I am expecting the August six-month change in core PCE to be around 3.2 percent annualized.
I am guessing that the majority of the FOMC would view this as evidence of ongoing disinflation (3.1 < 3.2). Or, if not, I am guessing at least that the majority would not view it as evidence of reacceleration that requires a hiking cycle to begin this week. Instead, I suspect that they would prefer to see how the next few months of data unfold.
* I suspect that the August CPI print did not change the view of the center of gravity of the committee that, without higher energy prices and tariffs, underlying inflation would be closer to 2.5 percent than to 3 percent. For example, the August CPI report did not show strong evidence of inflation creeping into core services (at least relative to July). In August, core services CPI printed at 3.0 percent over the year. In July, the same measure was 3.0 percent.
So if in July you thought that the economy was experiencing some disinflation, and that above-target inflation was largely driven by supply shocks, then the August PCE report we are likely to get would likely not be enough to move you off that view.
4. FINANCIAL CONDITIONS ARE TIGHTENING
Over the past couple weeks, financial conditions have tightened, which Chairman Warsh and others on the committee could argue is doing the work that a potential increase in the funds rate was meant to do.
5. TO BE CLEAR, I WOULD RAISE RATES
To be clear, my core argument is that not enough has happened since the July FOMC meeting that views should move in either direction. In July, if you thought that the federal funds rate was too low, then you should still think the federal funds rate is too low. And in July, if you thought the federal funds rate was at the appropriate level, then you should still think it is at the appropriate level.
My own view is that the federal funds rate is too low and that the Fed should increase the funds rate this week. I would have voted for a rate hike in July (and earlier; I was opposed to the cuts in 2025).
The center of gravity of the FOMC has not agreed with that throughout 2026 — including as recently as July. I suspect the data that have come in since the July meeting have not changed their view. I am expecting the Fed to hold this week, though I would not be shocked if I turn out to be wrong.

Sicily has a four-legged early warning system for Mount Etna. It has a beard, it eats gorse, and it is beating several million euros of monitoring equipment by half a day.
The shepherds have known this for as long as anyone has kept goats on that mountain. The herd tells you. No drama about it, no bleating, no rearing up and pointing at the summit. They simply decline to go up the hill that morning, and if the goats will not go up, neither do you. Oldest volcano warning system in Europe. Costs nothing. Runs on scrub.
For most of history the scientific response to this has been a polite nod and a change of subject.
Then in 2011 a German turned up with a box of trackers.
Martin Wikelski of the Max Planck Institute of Animal Behaviour has an unfashionable habit of asking local people what they already know before deciding they are simple. He collared goats living year-round on the slopes and started logging where they went, and when, and how fast.
On 4 January 2012 the data went peculiar. The animals turned down the high pastures they use every day of their lives, all of them, and headed for the trees. The seismometers were quiet. The gas monitors were quiet. In a control room in Catania, a great deal of very expensive equipment was reporting a perfectly ordinary Wednesday.
That evening Etna started throwing lava and ash into the sky.
Six hours.
The same signature has now turned up before eight major eruptions, and at the extreme the goats move fourteen hours ahead of the mountain. Ahead of the tremor. Ahead of the gas. Ahead of everything the volcanologists are paid to watch.
Nobody knows how they do it. The best guess is sulphur dioxide and hydrogen sulphide venting beforehand at concentrations no human nose could ever find, which would mean the animals are smelling the future and declining to comment. Wikelski's own summary is that they know in advance, we have no idea how, but they do.
The institute says there is not yet enough data for a formal warning system. More eruptions, more animals, more species. Which is the correct scientific answer and a very funny one, since the shepherds reached sufficient confidence somewhere around the Bronze Age and have been acting on it every day since.
Rome had geese who saved the city by making a racket when the Gauls came over the wall, and honoured them for it every year afterwards.
Etna has their spiritual successors, doing the same job by refusing to walk uphill.
We have a word in English for a man who behaves like a goat. It means he eats anything, wrecks anything, and understands nothing.
The goat currently outperforms a seismograph.

Hard to have faith in the JOLTS data when only about 25% of firms agree to participate when the BLS asks, and only around 30% of them respond in time for the first estimate. Only healthy businesses likely opt in. The LinkUp and Indeed measures of openings, which have deteriorated slightly this year, are more credible.

Marc Andreessen on how @elonmusk works:
"He has an operating method that he's developed that I would say is very unusual by modern standards. I'm not aware of another current CEO who operates the way that he does."
"The top-line thing is this incredible devotion from the leader of the company to fully, deeply understand what the company does and to be in the trenches and talking directly to the people who do the work."
"Basically what Elon does is he shows up every week at each of his companies, he identifies the biggest problem that the company's having that week, and he fixes it."
"He does that every week for 52 weeks in a row, and then each of his companies has solved the 52 biggest problems that year."
"Someone who used to work in one of the other aerospace companies and went to work at SpaceX said... 'It's like being dropped into a shocking zone of competence.'"
"Most of us never have that experience. Most people are never in an organization where the bar is held that high."

This AI just exposed the BIGGEST legal insider trading operation in America.
A platform called GovGreed built a seven-layer machine learning system that cross-references every stock trade disclosed by every sitting politician against the bills their committees control, the campaign donations they receive, and the companies their votes directly impact.
It scored all 540 politicians currently in Congress. And the numbers are crazy:
56% of every stock purchase made by Congress in the last 16 months was on a stock directly affected by a bill the buyer later voted on. That is 6,170 out of 11,016 total purchases.
More than HALF of all congressional stock buys are on companies whose fate that same politician is about to decide.
343 of 540 Congress members actively trade stocks while holding access to nonpublic legislative information.
That is 63.8% of the entire legislature making market bets with an informational edge that would put any hedge fund manager in prison.
The AI identified 752 active "Triple Signals" in the current Congress. A Triple Signal fires when three conditions line up at once:
The politician sits on the committee controlling a bill, they traded stock in a company affected by that bill, AND they received campaign contributions from that same industry.
Bills carrying these insider indicators pass at 5.4 TIMES the normal rate.
Now look at the individual leaderboard:
- Nancy Pelosi's estimated portfolio sits at $194 million with a Greediness score of 98.1 out of 100
- Ro Khanna made 13,231 trades across 800+ different tickers
- Michael McCaul made 32,302 trades and filed 6,670 of them late
- Thomas Suozzi filed 86.4% of his trades late with an average delay of 396 days, meaning his disclosures landed over a YEAR after he made the trade
And then there is Lisa McClain, the fourth-ranking Republican in the House. She has made 1,443 trades in three years, more than 98% of all politicians tracked.
She violated the STOCK Act twice in a single year, disclosing up to $900,000 in trades months after the legal deadline. Her husband bought up to $250,000 in Elon Musk's xAI, which quietly converted into SpaceX equity before last Friday's $2 trillion IPO.
The penalty for all of this? A $200 fine.
The number of Congress members ever prosecuted under the STOCK Act since it passed in 2012? Zero.
And the cruelest part is this:
A bill to ban congressional stock trading was introduced in January 2026. It has bipartisan support. Over 80% of American voters want it passed.
But Congress is sitting on it, because the people who would have to vote yes are the same people making millions from the system staying exactly the way it is.
They write the insider trading laws, they exempt themselves from enforcement, they trade on the information those laws generate, and when they get caught, they pay a fine that is basically nothing.
The AI didn't discover anything Congress was hiding. It just organized what was already public into a pattern so obvious that nobody can pretend it isn't there anymore.
