THE PANEL'S BRIEF, WRITTEN BEFORE THE OUTCOME

Panel sits at 17% that CPI >0.6% in Sept 2026, with a 35-point high, low split

The panel mean is 17% and the median is 17%, with forecasts ranging from 3% to 38%. Most records give low probabilities, clustering below 25%. The panel splits between a small group assigning up to 38% and a small group near 3%, but individual records contain no stated theses or drivers to explain their views. The single argument doing the most work is the panel's broad, low consensus probability itself.
