Column: A 68% December Hike Is a Price, Not a Forecast — and It Rests on Two Prints
The market has spent a week treating a 68% probability as a plan. It is an arithmetic output of two inputs — Wednesday's ISM services prices-paid reading and the November 12 CPI — and both can move without the Committee saying a word.
There is a habit in rate markets of reading a probability as a promise. When fed funds futures price a 68% chance of a December hike, the number gets reported as though the Committee had scheduled one and left the venue to be confirmed. It has not. The October 28 statement held the target range at 3.75%-4.00%, kept the language about additional adjustment, and handed the decision to two data points that have not yet been published.
The first is Wednesday's ISM services prices-paid index. Services inflation has been the sticky half of this cycle and the survey has tracked the PCE services ex-housing series with a two-month lead for most of the past three years. The second is the November 12 CPI, which arrives five days after the November 6 payrolls and three weeks before the meeting. Between them they carry most of the information the Committee says it needs. Everything else this week — manufacturing, refunding, Michigan expectations — is context.
That is why the current pricing is unstable in a way the headline number hides. A 68% probability implies roughly two-to-one odds, but the distribution around it is not symmetric: a prices-paid print below 55 probably takes December to 40%, while a print above 60 takes it to 80% before CPI is even released. The market is not 68% confident about the economy. It is 68% confident about a survey that has not been conducted yet, and that is a different claim.
There is a reasonable case for the hawkish side that does not depend on the surveys at all. Headline inflation has been above 3.5% year over year for two quarters, the labour market is cooling from a position of strength rather than weakness — claims at 194,000, payrolls at 125,000 — and a committee that has already raised rates this year has every incentive to finish the job while unemployment is still near 4%. Holding in October and hiking in December is a coherent strategy: it preserves optionality while signalling resolve.
The counter-case is equally coherent. Real policy is restrictive, the ten-year sits well above the funds rate, and the disinflation in goods has not yet finished working through services. A committee that hikes into a slowing labour market on the strength of one survey print risks the same error in reverse that it made in 2021. Neither argument is decided by arithmetic. Both will be decided by a number published at ten o'clock on Wednesday and another published five days later — which is why the honest way to hold a 68% probability is with a hedge, not a position.

Column: Soft Landing and Stagflation Are Not Mutually Exclusive — and That Is the Real 2027 Risk
Markets are treating the post-jobs relief rally as a clean soft-landing signal, but the data increasingly describe an economy where growth is fine, inflation is sticky, and the policy rate stays higher for longer than either bulls or bears currently assume.
Column: The Oil Market's Real Shortage Is Spare Capacity, Not Barrels
With Brent above $114 the debate has fixated on geopolitics. The structural story is quieter and more durable: the world's buffer of swing supply has thinned to its lowest level in decades — and it is not coming back quickly.
Column: The Fed's Hawkish Turn Is a Supply-Shock Story, Not a Demand One
The death of the easing narrative this fall is rooted in an energy-driven supply shock, which means the Fed is tightening into an inflation it cannot directly control — a position that carries real risk for the real economy.
