October CPI Arrives Without a Year Rate as December Hike Odds Hit 76%

The last inflation print before a December decision arrives Tuesday, and it does so with an unusual handicap: the October consumer price index will publish no year-on-year headline rate because of the 2025 federal shutdown's data gap, leaving monthly moves — consensus around 0.3 per cent headline and roughly 0.2 per cent core — as the market's entire decision input ahead of a Federal Reserve meeting that prediction markets now price as a 75-to-77 per cent coin-flip in favour of a hike.

The stakes are unusually high for a single monthly release. September's CPI showed a 0.6 per cent monthly rise that shocked markets and pushed year-ago comparisons to 3.7 per cent; Friday's blowout jobs report — 165,000 additions well above consensus — then repriced the December meeting from about 65 per cent hike-odds to 76.8 per cent on the CME's FedWatch futures, with Kalshi and Polymarket settling at 75.4 and 76.5 per cent respectively over the weekend.

Why this CPI has no year-on-year anchor

The missing year-on-year figure is a genuinely distorting artefact. The federal shutdown of 2025 suspended collection long enough that the Census Bureau's seasonal-adjustment machinery cannot compute a clean twelve-month comparison for October; without it, hedonic and base-effect modelling around this specific print is unavailable, and analysts will be reading headline months against a September that itself printed at an elevated 0.6 per cent. If October prints at the 0.3 per cent consensus, the implied deceleration would read as a pause in the build-up; if it prints 0.5 per cent or more, the last CPI marker before the December 8–9 meeting will have accelerated for two consecutive months.

The Cleveland Fed's five-year breakeven — 2.26 per cent — suggests the bond market expects inflation to cool regardless of what Wednesday's futures are pricing, and the Treasury curve's shape agrees: ten-year yields sat just below 4.88 per cent on Friday's close, having barely moved as equity markets bounced. That divergence between bond-market expectations and futures-predicted rate action is the underlying instrument of the CPI debate: bonds are buying the disinflation thesis, futures are selling it.

The Fed's awkward December

Federal funds already sit at an effective 3.88 per cent against a 3.75-to-4.00 target range, and the committee has spent the policy year cutting from the level that previously anchored the inflation fight to the level that may now have to anchor the inflation resume. A 25-basis-point hike on Dec 9 — the first such move after six months of cuts — would validate the Cleveland Fed's inflation data reading while risking a repeat of the 2023 mispricing that followed rate cuts too early, when momentum-driven hiring and pay re-accelerated just as the easing cycle was declared done.

Notably, the risk calculus has inverted from where the committee began the year. New York Fed's John Williams said last week that inflation is "still too high", a rare explicit signal that the committee is not done with the price-stability problem; the jobs report then gave hawks the employment-strength leg they needed to argue for action. For markets the question is narrower and binary: does this CPI marker force a dissent, or does it confirm a hike that both sets of market inputs — bonds and futures — have already been pricing for a fortnight?

What a repriced Fed path does to the world

The transmission is fastest in commodities and dollar-sensitive assets. The dollar index had its biggest one-session gain in five months on Friday's jobs print and briefly touched 102.2 by Monday morning before easing; gold held near $4,070 on Friday and rebounded over $4,100 on Monday with softer oil — both leg from relatively mild global easing optimism against a December path that is less certain to hold. For emerging-market central banks, the difference between a hike-no-hike decision in an already-priced-out policy framework is more material than the move itself: a confirmed hike supports dollar strength into the New Year and puts pressure on local-currency yields in Nigeria, Ghana and Kenya that were just beginning to stabilise.

Nigeria's policy linkage is direct but manageable. Domestic bond yields currently price naira inflation risk and the CBN's own policy path — not the Fed's — but the external leg still matters: a stronger dollar tightens trade finance, raises the cost of FX hedges and dampens portfolio appetite for frontier-market risk, a pattern Nigeria's equity market has spent this week absorbing (delivering a N3.52 trillion loss of market value in the last trading week).

The week's calendar beyond CPI

The CPI is the week's anchor but not the whole calendar. China's October trade data lands Wednesday, and market attention has shifted to the industrial capacity and consumer inflation readings released Monday that showed factory-gate inflation accelerating to 5.7 per cent — a potential cost-push signal for Western inflation that central banks have been forecasting but not yet measuring. Friday brings US producer prices, forecast at 0.4 per cent month-on-month, which — since PPI feeds through to CPI with a lag — will either confirm or refute the acceleration thesis that the CPI market is currently betting on.

Also on the calendar: UK GDP Thursday, Japan corporate goods prices and Nigeria's own November auction calendar — items that matter for each market's own rate path, but which the December Fed decision will dominate through its live impact on global discount rates.

Whatever Tuesday prints, the world has already made up its mind about the direction of the December trade — the only question is whether the Federal Reserve signs the contract in twelve days or forces the market to re-read the terms.
