Stock market open today, and the latest inflation print is the driver: the Consumer Price Index rose 0.4% in October while Wall Street priced a December rate hike at 100%. That leaves stocks facing a cleaner policy signal but a tighter borrowing-cost path.
October CPI and Wall Street
0.4% in October translates into an annualized pace of about 4%, well above the 3.7% rate in September. The move pushed analysts to expect the U.S. Federal Reserve to keep pressure on inflation rather than pause after its September increase of 25 basis points (hundredths of a percent).
100% odds for a December hike come from the FedWatch tool at CME Group, which tracks futures pricing in the 30-day Fed Funds Futures market. If that pricing holds, borrowers are looking at another step-up in rates before year-end, and equity valuations face the same discount-rate pressure that has already shaped this rate-hiking cycle.

Federal Reserve pricing
25 basis points is the size of the September move, and it matters because markets are treating that hike as the floor, not the ceiling. The odds of additional hikes in January 2027 and April 2027 are also rising, which tells traders the October CPI reading did more than nudge expectations; it reset the path for the next several policy meetings.
20% is the scale of the S&P 500 bear-market decline tied to the Federal Reserve's last rate-hiking cycle, a reminder that tighter policy can hit stock prices long before it hits the broader economy. That history does not guarantee a repeat, but it is the benchmark Wall Street is using as it recalculates earnings and valuation multiples after the October inflation data.

Inflation, oil, and costs
86 per barrel is where West Texas Intermediate traded on Nov. 11, down from $113 in April and up from $57 at the start of 2026. Energy costs feed into transport and goods pricing, so a firmer oil market keeps the inflation mix sticky even when headline readings move only modestly month to month.
25% of the world's seaborne oil crosses the Strait of Hormuz each day, so any disruption in that route can ripple into fuel and freight costs fast. The U.S. and Iran have been at war since February, and Saudi Arabia and Yemen are also locked in an ongoing conflict, which keeps energy traders watching the supply side while inflation stays elevated.

October 2025 gap
October 2025 brought a separate problem: the Bureau of Labor Statistics did not publish inflation data because of the government shutdown. That gap helps explain why a single 0.4% monthly reading now carries so much weight for traders, who are using the released October data to infer the pace of the next Fed move instead of waiting for a smooth run of reports.
4% annualized inflation is the number now shaping the trade, and it leaves consumers and businesses facing the possibility of higher rates before the year ends. The open issue is not whether the market has moved on the data; it has. The question is how much another hike would change borrowing costs if the Fed follows through in December.
