The PRO File - Issue No. 1 - The Fed Raised Rates. The Bond Market Said it Wasn't Enough.

1 · The One Thing

On September 16 the Federal Reserve raised its benchmark rate for the first time in roughly three years. That was the headline. It was not the important part.

Over the following two weeks the bond market repriced. The ten-year Treasury yield went from 4.75% at the end of August to 5.29% at the end of September — a move of 54 basis points in a single month, to a level the United States has not seen in about two decades. Treasuries closed out one of their worst quarters in a generation.

The Fed raised rates. The bond market said it wasn't enough.

If someone asks how the market did in September, there is no honest single answer.

The Nasdaq finished the month up 1.86%. The Russell 2000 finished down 5.40%. That is a spread of more than seven percentage points between two American stock indexes over thirty days. The Dow fell 4.29%. The S&P 500, which sits between them, was down less than half a percent and tells you almost nothing about what happened underneath it.

The split was not random. Large technology companies with their own cash and little need to borrow held up. Smaller companies, which borrow more and refinance sooner, did not. Neither did the dividend-paying industrials and staples that investors had been holding as bond substitutes — when real bonds started paying 5%, those positions had to be repriced.

It is also worth noting where the month turned. The S&P peaked on September 21 and gave back about 1.5% over the final seven sessions, as the bond move accelerated.

3 · The Economic Picture

Start with the inflation report, because everything else followed from it.

The August figures, released September 11, showed headline consumer prices holding at 3.4% year over year, with energy doing most of that work — gasoline up more than 27% from a year earlier and fuel oil up over 50%. Strip food and energy out and the picture inverts. The annual core rate eased to roughly 2.4%, its lowest since early 2021, with shelter inflation continuing to moderate.

The Fed raised anyway on September 16, taking the target range to 3.75%–4.00%. The reasoning, as articulated, is that an energy shock which persists long enough stops being a relative price change and starts becoming an inflation expectation, and that the cost of finding out late exceeds the cost of acting early.

Then the bond market went further than the Fed did. Yields rose across the curve, and the long end rose most: the ten-year closed September at 5.29%, up 54 basis points on the month and 111 basis points on the year. Three things appear to be driving it — persistent inflation that is no longer obviously falling, expectations that rates stay higher for longer, and a growing unease about how much government debt the market is being asked to absorb. The third is the one that has changed most this year, and it is not a United States story.

The rest of the economy looks steadier than that would suggest. Weekly jobless claims fell for a fourth consecutive week to roughly 197,000, announced layoffs declined in September, and second-quarter GDP was revised to 2.2% growth. This is not a bond market reacting to a recession. It is one reassessing what it should be paid to lend.

Whether the Fed has this right is a genuinely open question among people who do this for a living, and we are not going to pretend otherwise.

4 · Beyond Our Borders

The bond move was not an American event. Government borrowing costs hit multi-decade highs in Germany, Japan and the United Kingdom during September, and France has become the focal point, with its government now proposing tens of billions of euros in spending cuts to settle investors down. When every developed government is borrowing heavily at the same time, they compete with each other for the same buyers, and the price of that borrowing goes up everywhere at once.

The energy picture changed shape as well, and the change matters more than the headline price. Crude supply has eased — flows through the primary corridor for seaborne crude returned to roughly pre-conflict levels by the end of the month. The shortage moved downstream. The problem now is refining capacity, not barrels: diesel prices reached record levels, Chinese refiners were reported to have halted October fuel exports, and the White House has asked European governments about releasing diesel stockpiles.

That distinction is not academic up here. Diesel is the input cost for nearly everything that moves by truck, which describes most of the goods economy in the U.P. and northern Wisconsin. Heating oil and propane follow the same refined-product market, and we are about six weeks from needing them. A family that heats with propane and drives forty minutes to anything is exposed to this in a way the national inflation rate does not capture.

5 · On the Calendar

What is scheduled next month. These are dates, not predictions.

• October 14 — September consumer price index. The first read on whether the energy pass-through is reaching core.
• Mid-October — third-quarter earnings season begins, led by the large banks.
• October 27–28 — Federal Open Market Committee meeting. No updated projections at this one.
• Throughout October — Treasury auctions. These were a formality for most of the last decade and are now worth watching, because how they are received is the clearest read on the question September raised.
• Early November — the midterm elections, which historically coincide with a pickup in volatility that has little to do with the eventual result.
• Throughout — weekly energy inventory data, with refined products now more informative than crude.

6 · How We Are Thinking About Risk

Last month these would have been hypotheticals. September turned all three into things that actually happened, which makes this a better month for learning than for acting.

CORRELATION. For most of the past two years, stocks and bonds diversified each other reasonably well. In September they did not — both fell, and they fell for the same reason. That is the specific condition under which the stock-and-bond relationship has historically broken down, and it is worth knowing whether a portfolio was built assuming bonds would cushion an equity decline. The assumption is not permanently wrong. It was wrong in September.

CONCENTRATION. A seven-point spread between the Nasdaq and the Russell in one month is the clearest illustration of this we have had in a while. When a small number of large companies carry an index, that index stops being an accurate description of the risk anyone is actually holding. Broad exposure and concentrated exposure can look identical on a year-to-date chart and behave nothing alike in a month like this one.

THE REAL RATE. This is the one that matters most, and it cuts both ways. A ten-year Treasury at 5.29% competes for a dollar in a way it has not in about twenty years, which changes the arithmetic on how much equity risk is worth taking. For someone drawing an income from a portfolio, that is not bad news — safe assets paying a real return is the environment retirees spent the last fifteen years without. It does mean that a plan built when cash and bonds paid nothing was solving a problem that no longer exists in the same form.

None of that argues for doing something dramatic. It argues for knowing, in advance and in writing, what would.

7 · What This Does Not Change

If you are a client, here is the part that matters most, and it is the same every month.

Your plan is not built on a forecast of oil prices or Fed policy. It is built on what your life costs, where the money comes from in the years when markets do nothing, and what happens to the survivor. None of those three things changed in September.

What did change is a price, and prices move. A month in which the Dow fell 4% and the Nasdaq rose 2% is a month in which almost everyone can find a number that confirms whatever they already feared. That is a reason to look at your own plan rather than at an index.

A month of unusual headlines is the wrong reason to change a structure built for thirty years of them. If something in your own life changed this month — a health event, a liquidity need, a business development, a date that moved — that is a reason to call. The news is not.

8 · The Bottom Line

The Fed moved a quarter point and the bond market moved twice as far. What the long end is repricing is not next year's inflation but the cost of lending to governments that are all borrowing at once — and that is a slower, more consequential question than any single Fed meeting.

We will tell you in January how that looked in hindsight, including the parts we read wrong.

In a month this split, the index tells you very little about your own account. If you would like to see how your portfolio actually behaved in September, that is a twenty-minute conversation and we are happy to have it.
