  1. Forecasting Fed Funds Rate Group 4 Neelima Akkannapragada Chayaporn Lertrattanapaiboon Anthony Mak Joseph Singh Corinna Traumueller Hyo Joon You

  2. Background • Fed funds rate (FFR) as an instrument of control. • FFR as sign of economic strength/weakness. • FFR is at 1.25%, the lowest since 1961. • Greenspan intimates at possibility of deflation (last week). • Japanese Deflation and the Great Depression.

  3. Objectives • What will happen to the FFR given indicators such as GDP, CPI, stock market price levels, etc? • Create a distributed lag model with FFR as the dependent variable. • Provide one period ahead forecast of FFR. • And what does this forecast mean to us? • Provide economic context for the forecast.

  4. The Idea • Supposing that the Fed made its decision solely on previous FFR would be naive. • Fed’s decision on future FFR depends on existing information. • We focus on these existing information to explain FFR. • GDP • CPI • SP500

  5. Data Standardization • All data from Fred II. • Different time range and frequencies • But same time range and frequencies necessary for DL model • Lower bound set by data with the latest start (SP5000 Jan 1970) • Upper bound set by data with the earliest end (GDP Jan 2003) • Frequency set by data with lowest frequency (GDP quarterly). • Result is a shorter and less frequent data set (120 obs). • Still enough data.

  15. Summary • Standardization of data for DL modeling causes results in fewer observations. • Granger test is useful in isolating independent variables. • dlSP500 did not have AR structure. Creating the transformed dependent variable may have been more difficult. • Result is more plausible than ARMA model. • Fed funds rate will go down next quarter.

  16. What Now? • Assuming that fed funds will continue to go down, one can… • buy treasury bonds now and sell them later at a higher price when interest rate drops • simply try harder to find a job in the sluggish economy • start a business now in anticipation of next boom
