The New York Fed Staff Nowcast has been running for over three years. Each Friday at 11:15 a.m., we publish our updated predictions for real GDP growth based on the data released each week. When the Bureau of Economic Analysis (BEA) releases the first estimate of GDP growth, we stop updating our nowcast and archive it. We maintain these archives as part of our Nowcasting Report on the New York Fed’s public website to allow users to study the features of the nowcast and its accuracy. Now, to better understand the model and its performance during different cyclical episodes, we are publishing extended historical archives of the nowcast. Doing so provides fourteen additional years of forecasts that can be used not only to evaluate our nowcast model, but also to explore daily U.S. economic history through the model’s lens.
