What moved the number
- Pushes probability down
The latest reading of real GDP growth is 2.2% (2026-04), 2.20 pts above the 0% threshold with 10 quarters to go.
- Pushes probability up
Over the last decade, real GDP growth has typically moved 3.48 pts over 10 quarters. Closing the gap needs a 0.6-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 22%.
- If the next reading came in 0.5 pts lower (1.7%), the historical models would read about 35%.
