As flagged in our preview, the BLS did not publish 12-month changes for most series this time, because it collected no October 2025 data during last year's government shutdown.
Core Hit the Number Waller Named
The core reading matters more than usual this month. On Monday, Fed Governor Christopher Waller said a 50-basis-point hike at the December 8-9 meeting "should be considered" if October core CPI came in "around 0.3% or higher again," according to FXStreet's summary of his remarks. He said he would back at least a quarter-point hike even if the data improved. FXStreet reported that futures priced 0% odds of a half-point move before he spoke, and that December hike odds had risen to 84.2% on Monday.
A 0.3% core reading is exactly the level Waller described. That doesn't mean the committee will move by 50 basis points, but it does mean a bigger hike is now a live question for rate markets rather than a fringe one.
Where the Extra Tenth Came From
The BLS breakdown points to food and services rather than gasoline:
SPY Stayed Inside Its Same-Day Straddle
On Monday's close, SPY's November 10 $753 straddle cost about $6.08 on Cboe midpoints, roughly 0.81% of the $752.69 close, with breakevens near $746.90 and $759.10. In the first minutes after the release, Yahoo Finance premarket data showed SPY falling from about $753.40 at 8:29 a.m. ET to $749.92 at 8:30 and $749.67 at 8:38, about 0.4% below Monday's close.
That is a move in the right direction for put holders but well short of the straddle's lower breakeven so far. If SPY opens around that level, the same-day straddle would be worth roughly its intrinsic value of about $3.30 plus whatever time value is left, compared with the $6.08 paid. That gap is the CPI event premium leaving the options. Live quotes are on Cboe's SPY page.
Longer expirations carry less of that premium per day. The November 12 straddle priced about 1.31% on Monday, so a 0.4% drop eats less of its value, but it also keeps exposure to whatever follows the open.
Rate-Sensitive Growth Took the Bigger Hit
The reaction was larger outside the S&P 500. Yahoo Finance showed QQQ at $672.03 at 8:38 a.m. ET, about 1.1% below its $679.35 close, and the small-cap IWM about 0.7% lower at $280.47 from $282.51. TLT, the long-Treasury ETF, slipped about 0.4% to $81.64 from $81.96, consistent with higher yields. Nasdaq-100 futures were already down about 0.4% before the data, according to Quartz.
For options traders, that spread matters. A hot inflation print tends to hit long-duration growth stocks and small caps harder than the broad index, so the same headline can produce very different outcomes in SPY, QQQ and IWM contracts.
