With 10 days left within the Third Quarter, plainly a number of people have been obsessing in regards to the varied GDP Now forecasts. The considering is the info will influence how the FOMC will decide whether or not we get extra fee will increase or if it’s larger for longer, and even probably reflecting a 2024 recession and Fed fee cuts.
Now Casting was first developed by the Federal Reserve Financial institution of Atlanta to offer a real-time estimate of GDP development for the present quarter. It makes use of (13 or so) inputs1 to extrapolate a tough approximation of financial development. The NY Fed subsequently added its model, as did different regional Fed banks.
Whereas these varied Now Casting websites are helpful as thought workouts, we run the danger of taking them too actually. The outcomes from these vary from being pretty correct, often being off just a little to being wildly incorrect.
That is the character of the beast.
As we progress deeper into the three-month quarter, increasingly more knowledge turns into accessible. As GDP Now updates its mannequin with the most recent knowledge, it turns into extra correct. By the point the quarter ends, GDP Now could be fairly good — the typical error is about 0.5% factors, plus or minus.
