The Overnight Rate

Decided on Thursday

The hike got priced before the inflation number printed. Here is what today's release has left to decide.

FRIDAY, SEP 11, 2026Issue 003

If something cannot go on forever, it will stop.

Herbert Stein, chairman of the Council of Economic Advisers, 1986

The inflation number lands at 8:30 this morning. The decision it was supposed to inform got made yesterday afternoon.

Who pays: diesel

Diesel is not a household purchase for most people, which is why a 24.1% monthly jump reads as somebody else’s problem. It moves freight. Freight is inside the price of everything that arrives at a grocery store on a truck, which is nearly all of it.

The lag is weeks, not days. So yesterday’s producer number is really a preview of what you pay in October, and the Fed knows it, which is most of why the hike repriced before anyone saw a consumer number.

Threshold, 8:30

Consensus is 3.4% (Kiplinger). As of this morning, Polymarket has 3.3 at 30% and 3.4 at 48%, so 78% of the money sits on one of those two, and either is a Friday. That split has swung around all week without changing the answer.

Here is what changed since yesterday. With the hike already in the sixties, a hot print no longer decides anything; it confirms. What is still live is the second hike. A 3.5 or higher, 18% of the money, and I would expect the two-or-more market to move first and September to go from likely to settled. A 3.2 or lower, about 9%, is the only outcome left that can still surprise anyone, and it would put the hold camp back in a room they were escorted out of on Thursday.

I score it at 8:31, with this paragraph quoted, so nobody has to trust my memory of what I expected.

The Bug Report

First Friday column. One ticket. Our own miss goes first.

TOR-0002
Expected:        "The print decides how loud the answer is."
                 The Overnight Rate, Issue 002, Sept 10
Actual:          The hike repriced 52 to 64 during Thursday, on producer
                 prices and energy, with CPI still unprinted.
Severity:        Medium. A reader who took that line literally and waited
                 for Friday watched a twelve point move without him.
Owner:           The Overnight Rate
Odds at filing:  Sept 16 hike 64% (Polymarket, Thursday evening)
Status:          Won't fix. The threshold held. The assumption that the
                 consumer print was the only live input did not.

The FOMC dots miss, the energy-as-tailwind miss, and this morning’s CPI ticket stay on the backlog until /bugs is live.
