Yield curve and monetary policy expectations in small open economies

This paper estimates a New Keynesian dynamic stochastic general equilibrium (DSGE) model in small open economies using the yield curve data as well as standard macro data. The DSGE model is estimated on the data of three inflation-targeting small open economies (Australia, Canada, and New Zealand) using Bayesian methods. We find that the long-end of the yield curve is highly correlated with the current and future short-term interest rates determined by domestic central banks. Yield curve data are particularly informative about the future stance of monetary policy in Australia and Canada in that the correlation between the model-implied monetary policy expectations and the ex-post realized policy interest rates increases when the yield curve data are used in estimation. Unlike the estimation results solely based on the macro data that imply the cental bank’s relatively strong focus on inflation stabilization, our results using yield curve information suggest that even inflation-targeting central banks have a significant concern for output stabilization. We also document that persistent domestic shocks, not foreign disturbances, drive the average level of the yield curve in these three countries
