(WP 2025-02) How Does the FOMC Form Forecasts? An Adaptive Learning Approach Utilizing SEP Data

This paper examines how FOMC participants construct their Summary of Economic Projections (SEP) forecasts. FOMC expectations are assumed to contain two components: (1) an endogenous part that follows an adaptive learning model and (2) an exogenous part defined as sentiment (waves of optimism and/or pessimism). The results include key policy takeaways. The forecasts of FOMC members are responsive to new economic information. Their sentiment about future GDP growth and inflation also displays persistence and is correlated with each other. Moreover, FOMC participants rely more on their endogenous/learning model to form expectations. However, sentiment plays a larger role during and around recessions.
