Current Market Outlook

The market is pricing a 50% chance that month-over-month CPI in November 2026 exceeds 0.4%. This is a coin flip. The market sees the outcome as perfectly balanced, with no clear edge in either direction. For context, the November 2025 CPI print came in at 0.3% month-over-month, and the trailing 12-month average through late 2025 was around 0.25-0.3%. So the 0.4% threshold sits above recent trend, but not dramatically so.

Key Factors Driving the Odds

Three things explain why this market is stuck at 50%.

First, November is a notoriously volatile month for CPI. Seasonal adjustments for holiday spending, energy price swings, and end-of-year inventory sales create noise. Over the past decade, November CPI has exceeded 0.4% in four years and stayed below in six. The data is genuinely split.

Second, Fed policy uncertainty. By November 2026, the Fed will have had two years to respond to whatever inflation trajectory emerged from 2024-2025. If rate cuts happened aggressively in 2025, the lag effect could push November 2026 CPI higher. If rates stayed elevated, inflation could be subdued. The market has no consensus on where rates will be, so the CPI outcome remains a toss-up.

Third, energy base effects. Oil prices were relatively stable in late 2025. Any supply disruption from Middle East tensions or a hurricane season that hits Gulf production could spike energy costs directly into the November calculation. The 0.4% threshold is low enough that a 5-10% oil price jump alone could push CPI over the line.

What Could Change These Odds

Watch the October 2026 CPI release on November 12, 2026. If October comes in above 0.4%, the market will likely shift toward Yes, as momentum carries into November. If October is soft, say 0.1% or negative, the odds will drop toward 30-35%.

The Fed's September 2026 rate decision is another catalyst. If the Fed cuts rates, traders will price in higher inflation risk and push the November CPI contract up. If the Fed holds or hikes, the opposite.

Finally, the November 2026 election results matter. A new administration could mean new fiscal policy. Markets will adjust expectations for inflation based on the winner, though the direct effect on November CPI is limited since the month starts just after election day.
