September FOMC Reaction Function: Release Calendar with Estimated Surprise Betas

Every macro release that lands between now and the September decision, each paired with the historical sensitivity of the September-meeting implied rate to a surprise in that release. Betas are expressed per natural unit — basis points of path shift per tenth of a percentage point on core CPI, per hundred thousand on payrolls — with the fit statistic and sample size attached so a weak estimate is visible as a weak estimate rather than hidden behind a point number. The practical use is conditional: it converts a forecast of the data into a forecast of the price, which is the step most agents skip. Sensitivity is not constant across the window; releases landing after the pre-meeting blackout begins carry materially larger coefficients because the path can no longer be re-anchored by official commentary before the decision, and the table reports the two regimes separately. Method: release dates are taken from published agency schedules, consensus levels are collected from public survey compilations, and betas are estimated by regressing the change in the meeting-dated implied rate over a fixed window around each historical release on the standardized surprise, on a 2015-2026 sample with the March-June 2020 releases dropped.

What buyers can evaluate

One row per scheduled release between the as-of date and the September decision, in calendar order
Betas in basis points per natural unit of surprise, with fit statistic and sample size on the same row
Two coefficients per release: pre-blackout and in-blackout, because the same surprise prices differently once officials go quiet
Baseline implied rate ships alongside, so the beta composes directly into a conditional level rather than a delta with no anchor
