Q4 Survey of professional forecasters was released Monday. Growth is expected to accelerate without the yield curve inverting and triggering Sam’s rule.

The path to unemployment can be explained in terms of Sam’s rule.

This suggests that Sam’s rule triggers in July, although the interpolation procedure makes precise month timing tricky.
Interest rate forecasts are for a peak in the fourth quarter of 2023.

For Q4 2023, the 10-year forecast is 4.6%, compared with the 3.9% forecast in the last survey (August). Peak rates are postponed from the third quarter of 2023 to the fourth quarter of 2023.
