The yield curve inversion predictor of a recession (accurate for past 8 recessions since proposed by the guy in like 1986) may not be an indicator for the first time this time, the guy said.

The Fed is now overcommunicating in advance so much it obviates the need to even look at a yield curve (when they're basically laying out what they're gonna do). Some say.

Some say also that the absolute level of rates matters, and with interest rates at 0 what yield curve are you looking at?

Also the model was linked to inflation-adjusted yields. Inflation expectations are inverted, ie traders see inflation easing over time.
