The portfolio balance effect and reserve diversification: an empirical analysis
(759 kB) 
Summary for non-specialists(70 kB)
The purpose of this study is to examine whether the portfolio balance effect, operating through the outstanding debts of US and euro area, and the signaling effect of sterilized intervention, operating through the relative composition of official reserves of developing and emerging countries, explain the developments of the euro/dollar exchange rate. The empirical analysis reveals that both effects are statistically significant and have the correct signs. The Clark-West testing procedure indicates that the model which relates the exchange rate to official reserves and the interest rate differential outperforms the random walk model in the forecasting accuracy.
