IIIS Discussion Paper No. 404


Forward exchange rate unbiasedness hypothesis (FRUH) has been a widely researched subject for decades. Recently, the sample populations of these studies have expanded to include developing country currencies. The majority of these findings have been that forward rate biasedness is more pronounced for developed country currencies than it is for developing country currencies. One such paper (Frankel and Poonawala 2010) has further suggested that this phenomenon may contradict risk premium theory since developing country currencies are relatively more volatile. Our analysis first replicates the results of Frankel and Poonawala and then extends the study out of sample using an updated composition of currency classifications. The results of this extended period of analysis show that forward rate biasedness is less pronounced for developed country currencies than for developing country currencies and consequently does not establish grounds to challenge risk premium theory. Furthermore, our results are consistent with another branch of literature which suggests that conflicting FRUH test results may be particular to the time period examined. It is therefore possible to speculate that period-specific factors were responsible for the results found in previous research.

We look at recent evidence on whether the forward exchange rate is a good predictor of the future spot rate. We find that the evidence given to date is perhaps dependent on the time period of analysis and is not consistent across time. We also find that there is no evidence that emerging market currencies are more prone to forecast bias than developed market currencies
