Abstract

This paper investigates the response of US stock market uncertainty to monetary policy of the Federal Reserve Bank. It can be shown that monetary policy significantly Granger-causes stock market confidence. By using monthly closing prices of the VIX as a stock market uncertainty proxy and a copula-based Markov approach the stable nonlinear relation between confidence and uncertainty is demonstrated. The monetary policy effect on stock market uncertainty is therefore separable into a linear and nonlinear part.
