CPI Day: 82% Fed Hike Odds Hang Over S&P Rally
S&P 500 futures gain 1.56% ahead of October CPI, but Fed Governor Waller's December hike signal puts the nascent equity recovery on the line.
Key Points
- S&P 500 futures are up 1.56% to 7,517.50 heading into October CPI, but Fed Governor Waller endorsed a December rate hike just hours before the print, sending December hike odds to 82.2%.
- Markets are walking a razor's edge: headline CPI is forecast at +0.3% month-over-month — half September's 0.6% pace — but any upside surprise will collide directly with an equity market still rebuilding from last week's 4.4% single-day collapse.
- Watch the 10-year Treasury yield at 4.868% and the S&P 500's pre-November 4 level around 7,590 — a hot CPI print that pushes yields toward 5% could snap this recovery in a single session.
The number that matters most today is 0.3% — the consensus forecast for October's month-over-month headline CPI print — and whether the actual figure validates or blows up a stock market that is 1.56% higher in futures trading and desperately trying to convince itself the worst is over. With S&P 500 futures at 7,517.50 and Nasdaq 100 futures up 2.40%, the morning setup looks constructive on the surface. Beneath it, the Federal Reserve just lit a fuse.
The Fed's Problem
Federal Reserve Governor Christopher Waller threw cold water on the rally before it had time to breathe. Speaking Monday evening, just hours before Tuesday's CPI release, Waller explicitly backed a December interest-rate hike — a signal that rattled rate markets and pushed the probability of a December move to 82.2%, according to fed funds futures pricing. That is not a marginal probability. That is near-certainty, and it means the Fed has effectively pre-committed to a hike heading into the most consequential inflation print in months.
The stakes of this dynamic are hard to overstate. The Fed is not operating in a vacuum of uncertainty anymore — it has staked a position. If October's CPI comes in at or above consensus, Waller and his colleagues will look prescient, the December hike gets locked in, and the 10-year Treasury yield, currently sitting at 4.868%, has a clear path toward 5%. That yield level is not abstract. At 5%, equity valuations — particularly in long-duration growth names that dominate the Nasdaq — come under sustained mathematical pressure. The P/E compression that follows a 5% risk-free rate is not speculative. It is arithmetic.
What makes this more combustible is the sequencing. The S&P 500 collapsed 4.4% in a single session on November 4 following the US midterm elections, and as of Monday's close — after a 2.35% gain — Rabobank analysts note the index has only recovered to roughly pre-November 4 levels, up about 3% from the low. That is not a healed market. That is a market that has clawed back to even, with no margin for error walking into a potentially hawkish inflation print.
What the Data Actually Shows
The October CPI forecast calls for headline inflation to rise 0.3% month-over-month, a meaningful deceleration from September's 0.6% reading. Core CPI — which strips out food and energy and is the number the Fed actually cares about — is expected to moderate to 0.2% from 0.3%. On an annual basis, that trajectory would represent genuine progress. The problem is that "genuine progress" has been the story for six months, and the Fed is still hiking.
One of the few macro tailwinds available to equity bulls this morning is the oil complex. Brent crude futures fell 3.6% and slipped below $90 a barrel for the first time since August — a level that, if sustained, provides meaningful relief to the energy components of CPI. WTI crude was lower by 1.8%, hovering near $85.29 per barrel. Commodity disinflation of this magnitude can shave several basis points off headline CPI calculations, and it is part of why the consensus forecast is as benign as 0.3%. But headline CPI is not what the Fed targets, and energy's volatility cuts both ways — it was energy that helped push September's reading to 0.6% in the first place.
The volatility market is pricing today's event risk at approximately 0.79% for a one-day S&P 500 move, based on where VIX options are trading. That is not a large implied swing relative to recent realized moves. The VIX itself — currently at 19.92, down more than 22% from its November 5 spike to 28.36 — has collapsed with unusual speed given the structural uncertainty still present in the macro picture. Investor sentiment data confirms the unease: the AAII survey shows bullish sentiment falling to 34.1% from 37.8%, and the CNN Fear & Greed Index is registering 32, squarely in "Fear" territory. The vol market may be underpricing what a genuinely hot CPI number could do to an index that has only just crawled back to even.
What Traders Watch Next
The divergence in today's futures action is itself a signal worth parsing. At the open, Dow futures led with a gain of +1.38%, while Nasdaq 100 futures lagged at +2.40% intraday — but the Nasdaq is the most rate-sensitive of the three major indices, and its early volatility reflects exactly that sensitivity. The Russell 2000, up 1.97% in futures, is the most economically cyclical read: small caps tend to benefit from disinflation and suffer acutely when rates stay elevated, so the Russell's strength is implicitly a bet on a soft CPI print.
The chip complex is providing some of the strongest internal support to the Nasdaq this morning. Marvell Technology is up 9.49%, Micron gained 6.25%, and Intel added 5.49% in today's session — a broad-based recovery across semiconductors that partially offsets the 4.27% decline in Nvidia, which remains under pressure from a board investigation into CEO Jensen Huang that emerged last week. The divergence within chips is notable: the market is distinguishing between company-specific risk and sector-wide positioning, which suggests at least some return of discriminating capital allocation after last week's undifferentiated selloff.
After the close tonight, CoreWeave reports Q3 earnings, with analysts expecting a loss of $1.16 per share on revenue of $3.55 billion — a figure that would represent more than double CoreWeave's year-ago sales. Options are pricing a 20.89% implied swing around the event. CoreWeave carries meaningful debt and its capacity delivery timelines are under investor scrutiny, making it a cleaner read on AI infrastructure confidence than any of the mega-cap names. If CPI delivers a benign print and CoreWeave's report confirms demand momentum in AI compute, the technical setup for a sustained recovery improves materially. If CPI is hot, CoreWeave's implied move becomes directionally simple: watch the VIX at 19.92 for the first signal of how the market is interpreting the print in real time, and treat any push back above 23 as confirmation that the December hike narrative has fully repriced into equities. The specific level traders need to defend is 7,490 on S&P 500 futures — the lower bound of this morning's trading range — because a break there before CPI even drops would signal the market is not waiting to find out.
