Probability shifts this week

October FOMC: Probability the Fed Holds at 3.75-4.00% (Oct 27-28) — 0.90 → 0.94 (+4pp)

The hold consolidated from consensus into near-certainty in the final week before the decision. Kalshi closed the week at 93.5% for the hold, Polymarket no-change at 94.5-95%, and fed funds futures at 90% (predictionmarketpicks, Polymarket); the Reuters economist poll (Oct 16-20) came in at 94 of 100 for hold with all 100 expecting a December hike (Mitrade). The posterior stops at 0.94 rather than 0.97 because the fulcrum constraint (ID 270) is unchanged: a chair who repudiated forward guidance at the IMF (Oct 16) and refused to pre-clear the meeting retains a free surprise option against a ~95% hold consensus, and his inflationary justification — the hottest CPI/PPI combination since 2022 with Brent at a six-month high near $117 — has only strengthened through the blackout (CNBC). The week's rate move worked against the hike case: money markets stopped fully pricing a 2026 hike (Newsquawk, Oct 22) after a violent one-day Treasury rally took December off full pricing on AI-credit fear, not dovish data (Newsquawk, sembr).

December FOMC: Probability of a 25bp Hike to 4.00-4.25% (Dec 8-9) — 0.72 → 0.76 (+4pp)

The December branch firmed on unanimity and energy. The survey constraint reached its extreme — 100 of 100 economists in the Reuters poll now expect a December hike, against fewer than half a month earlier — and CME priced Dec at 82.8% (Oct 20), while Polymarket closed the week at 76.5-77% for the 25bp increase with the hike-pause-hike path at 75% (ProbaView, Polymarket). The countervailing development is the pricing edge inversion: money markets no longer fully price a 2026 hike after the ~19bp one-day rally (largest since Mar 10, 2023) drove the 10-year below 5% on Oct 22 — term-premium compression and AI-credit flight-to-quality, not the policy path, are in charge of the long end (CNBC, sembr). The energy constraint (ID 15) hardened materially into the satisfaction tests: Brent settled $116.72 on Oct 24, the highest since Apr 29, up 6% on the week and more than 10% in October, on Houthi strikes on Saudi energy infrastructure, a tanker spill off the UAE coast, and Trump publicly floating another strike on Iran (Petra/Bloomberg, The Star/Reuters).

New assessments

None. Both live macro assessments were updated this cycle; no situation crossed the bar for a standalone addition. The AI-credit channel is the closest candidate — global credit spreads hit their widest since May 2025 and the CoreWeave/Meta unwind drove a flight-to-quality bid that re-priced the December hike — but it is captured as an updated constraint (ID 232) and a watch item rather than a standalone assessment; it becomes one if a specific financing failure (issuer, fund, or gate) materializes.

Resolved this week

None. Assessment 12 resolves at its decision trigger in three days (Oct 28); assessment 18 was updated this cycle and resolves at the Dec 8-9 decision. Neither meets the staleness criteria.

New constraints

None. No new constraint crossed the bar this cycle. The week's material developments (AI-credit flight-to-quality as the long-end driver; the oil complex breaking $110 en route to $117; unanimous December survey conviction) were appended to existing constraints 15, 232, 246 and 270 rather than minted as new entries.

What to watch

The October decision is three days out and the hold is no longer a forecast — it is the entire surface of the market. The asymmetry is the story: the ~5% hike tail is cheap because a chair who repudiated forward guidance has demonstrated he will not be priced, and the justification for a surprise (hottest CPI/PPI since 2022, Brent at $116.72, inflation expectations rising with the five-year breakeven at 2.47%) is stronger now than it was when he declined to act on Oct 16. The press conference matters more than the statement: a hawkish hold that keeps December alive without pre-committing is the consensus script, and any terminal-rate language on a January extension is the marginal information.

The December branch carries the positioning edge, and the margin has compressed to a single point (posterior 0.76 vs ~77% market). The new tension is inside the constraint structure itself: the same AI-credit fear that took December off full pricing in money markets is the channel that would make the hike harder to deliver if it worsens, while the energy shock is the channel that would make it too small. The November 10 CPI sits between them. The bar is the assessment's base case: core at or above +0.25% m/m locks the hike branch; at or below +0.2% m/m re-opens the hold and vindicates the money-market unwinding. The PPI margin pass-through (trade and distribution margins on AI infrastructure buildouts) is the argument that the branch holds even if gasoline annualizes out.

The long end is now trading on two non-Fed drivers that pull in opposite directions: AI-credit flight-to-quality (10-year below 5%, largest one-day drop since March 2023) and the oil complex (Brent +6% on the week, closing at a six-month high as crude held above $100). Neither is the fiscal constraint (ID 232) itself, but both feed it — and the November 4 refunding is the next structural catalyst, with the dealer survey due Oct 26 potentially signaling the issuance-mix shift (Citi's $3bn long-end cuts, possible 20-year cancellation) against a 30-year that has held between 5.29% and 5.48% through the entire week. A dovish October hold should not be expected to rally the 30-year; the fiscal constraint clears on credible inflation and supply, not on Fed policy.

The energy overlay is the binary into both the November 10 CPI and the December decision, and it has escalated rather than consolidated. Trump has moved from "off the table until the midterms" to publicly floating "another Epic Fury" with the NYT reporting strike planning and practice flights over Iraq; Iran has responded by ruling out backing down, threatening undersea cables and Gulf bases, and denying any Hormuz-reopening offer. The November 3 election remains the timing anchor — a post-midterm strike resumption is the tail that re-prices the entire hike path, and it is no longer a tail on the downside of the price curve only.
