Abstract: This study proposes an alternative procedure for modelling exchange rates behaviour, which is a linear combination of a long-run function and a short-run function. Our procedure involves modelling of the long- run relationship and this is followed by the short-run function. Among all the possible combination of modelling techniques, we proposed the simplest form, namely modelling the long-run function by the well established purchasing power parity (PPP) based model and setting up the short-run function based on its time series properties. Results of this study suggests that our procedure yields powerful forecasting models as they easily outperform the simple random walk model--which is rarely defeated in the literature of exchange rate forecasting--in term of out- of-sample forecasting, for all the forecast horizons ranging from one to fourteen quarters. This study provides us with some hope of achieving a reasonable forecast for the ASEAN currencies using the fundamental monetary model just by a simple adaptation.
