What moved the number
- Pushes probability down
The latest reading of real GDP growth is 2.2% (2026-04), 3.90 pts below the 6.1% threshold with 6 quarters to go.
- Pushes probability down
Over the last decade, real GDP growth has typically moved 2.08 pts over 6 quarters. Closing the gap needs a 1.9-standard-deviation move.
What would change this
- If the next reading came in 0.5 pts higher (2.7%), the historical models would read about 17%.
- If the next reading came in 0.5 pts lower (1.7%), the historical models would read about 13%.
