September 2024 — Fed Language Drift

September 18, 2024

On September 18, 2024, the FOMC statement scored 13.8 for commitment density and 52.0 for epistemic certainty. Against the prior meeting, commitment held roughly steady and certainty held roughly steady. The press conference scored 12.7 and 50.6 on the same two measures.

What the statement committed to

Commitment density measures how much of the statement binds the committee to action rather than describing conditions. This meeting reads 13.8, little changed from 13.6 at the previous meeting.

How certain the statement sounded

Epistemic certainty measures how much certainty the language carries relative to doubt markers (certainty − 0.5×doubt, scaled). This meeting reads 52.0, little changed from 52.2 at the previous meeting. Higher means more certainty, not more hedging.

Commitment density and epistemic certainty across the trailing meetings. Commitment rises as the language binds the committee to action; certainty rises as certainty markers outweigh doubt markers. This meeting is highlighted.
