Inflation above expectations, employment weakening: how to read conflicting data

Two releases pointing in opposite directions

Two sets of US data for September 2026 point in different directions. On inflation: CPI rose from 3.4% to 3.7% year on year, the 0.6% monthly print was the largest in five months, core rose 0.3% on the month, and price increases were spread across a wide range of components — evidence that inflation stickiness has not cleared. On employment: payrolls added only 29,000 against a 90,000 forecast, July and August were revised down by a combined 60,000, and the unemployment rate rose to 4.2%.

Layer one: data quality and noise

Before comparing the two, look at how reliable each is. First prints of payrolls have always been revised substantially, and this release revised two months down by 60,000 in total. The participation rate rose 0.2 percentage points to 61.8%, and supply-side repair alone lifts the unemployment rate. By contrast, CPI's broad distribution across components is a more structural move that is harder to explain with any single factor.

The conclusion: employment data carries more noise, inflation data carries a more concentrated signal.

Layer two: weight inside the policy reaction function

The Fed's binding constraint is that inflation has not returned to target. At this stage, the marginal impact of inflation data on the policy path is typically larger than that of employment data. Actual market pricing confirms it: the cumulative probability of a hike before year-end has held above 85%, pricing a hold in October and a 25 basis point increase in December. Weaker employment has not yet changed that path.

Layer three: where expectations sit

The New York Fed survey shows one-year inflation expectations rising from 3.58% to 3.9%, with the three-year measure up 0.1 percentage point. Expectations are the hardest part of the reaction function to handle. While expectations are still rising, the weight of any single employment release is pushed lower still.

Layer four: when the weights would flip

If employment misses expectations for several consecutive releases while inflation expectations begin to fall, the weight shifts towards employment. Some institutional commentary also notes that the Fed may be divided on whether two consecutive meetings of action are warranted, and that rising long-end Treasury yields and a stronger dollar already constitute a degree of financial tightening. Those factors become dominant once inflation turns.

What it means for trading

While two datasets are in conflict, directional trades usually have a lower hit rate than normal while volatility runs higher. The better approach is to cut risk per trade, allow a wider stop distance, and focus observation on changes in policy pricing — the direction of pricing says more about the market's real judgement than the ups and downs of any single month's data.
