## DataSnack's read

**A hiking Fed makes a March hold depend on how the 2026 path ends**

March matters because it shows whether the Fed's step-by-step hikes end or continue into 2027. The model's case, 49% in seven days, rests on a further hike path in the Sep-Dec decisions pulling down the hold chance.

## The numbers

- The market's number (Kalshi) now: 39% ([the market](https://kalshi.com/markets/kxfeddecision))
- DataSnack's model, seven days from now: 27%
- The market closes: 17 Mar 2027
- How it resolves: If the Federal Reserve does a Hike of 25bps on March 17, 2027, then the market resolves to Yes.
- Record: It has no graded forecasts yet; the first is graded on 12 Nov 2026.
- Replay on the last 42 days: off by 10.6 points against 12.5 points for standing still; closer on 22 of 42 days
- Fitted on 376 days of history

## How the model works

A further hike path priced into the Sep-Dec decisions market pulls down the chance the Fed simply holds in March 2027. The market's own level is the base.

- Each move in the chance of a hike-pause-hike path shifts the March hold chance by -27% in log-odds. DataSnack's author expected -30%; the data say -27% ± 0.17, fitted on the same days the replay scores. A rough rule.
