The three-month average of the Chicago Fed National Activity Index (CFNAI) is expected to decline to +0.10 in tomorrow’s update for June, according to The Capital Spectator’s median econometric forecast. The projection is moderately below the previously released +0.18 reading for May, which reflected above-average economic growth relative to the historical trend. Only values below -0.70 indicate an “increasing likelihood” that a recession has started, according to guidelines from the Chicago Fed. Based on today’s estimate for June, CFNAI’s three-month average is expected to remain at a level that’s historically associated with growth, and at a moderately above-trend pace.

Here’s a closer look at the numbers, followed by brief definitions of the methodologies behind The Capital Spectator’s projections:

VAR-4A: A vector autoregression model that analyzes four economic time series to project the Chicago Fed National Activity Index: the Capital Spectator’sEconomic Trend & Momentum Indexes, the Philadelphia Fed US Leading Indicator, and the Philadelphia Fed US Coincident Economic Activity Indicator. VAR analyzes the interdependent relationships of these series with CFNAI through history. The forecasts are run in R with the “vars” package.

VAR-4B: A vector autoregression model that analyzes four economic time series to project the Chicago Fed National Activity Index: US private payrolls, real personal income less current transfer receipts, real personal consumption expenditures, and industrial production. VAR analyzes the interdependent relationships of these series with CFNAI through history. The forecasts are run inR with the “vars” package.

ARIMA: An autoregressive integrated moving average model that analyzes the historical record of the Chicago Fed National Activity Index in R via the“forecast” package.

ES: An exponential smoothing model that analyzes the historical record of the Chicago Fed National Activity Index in R via the “forecast” package.
