Reasoning
The June 2026 SEP median for year end 2026 funds rate was 3.8 percent, representing a 40 basis point increase from the March SEP median of 3.4 percent. For the December SEP to show a higher median, the committee would need to shift expectations upward again despite currently holding rates at 3.50 to 3.75 percent since June 17. This would require either a material deterioration in economic conditions prompting hawkish revisions, or incoming data (inflation, labor market, growth) that convinces the nine participants currently above the target range to push even higher. Historical precedent suggests SEP medians show considerable stability within the same year once set, and a second consecutive 40 basis point upward shift in just six months would be unusual absent a significant economic shock. The fact that the June meeting erased prior cutting bias and held rates suggests the committee views further tightening as less likely than it did in March, making another upward revision to year end forecasts less probable.Key uncertainty
Inflation data releases between August and December 2026 could force a sharper hawkish reassessment if price pressures re accelerate unexpectedly, or conversely, the committee may have already front loaded its hawkish revision in June and subsequent data may validate that the terminal rate path sits near 3.8 percent rather than above it.
