The determinants of ASEAN-5 real effective exchange rate vis-á-vis the UK pound

Purpose – The purpose of this paper is to present an empirical analysis of long-run and short-run forcing variables of purchasing power parity (PPP) for ASEAN-5 currencies vis-à-vis the UK pound, i.e. their real effective exchange rate (REER). Design/methodology/approach – This study uses a recently developed autoregressive distributed lag (ARDL) approach to co-integration (Pesaran et al. , 2001) over the period 1991:Q1-2006:Q2. Our empirical results suggest that the foreign interest rate ( R *) and domestic money supply (M1) are the significant long-run forcing variables of PPP for ASEAN-5 REERs for the three periods. Findings – In the short-run, the variables have different impacts during the sub-periods and full period for ASEAN-5 countries. The results suggest that the domestic money supply (M1) for Malaysia, domestic interest rate and foreign interest rate ( R *) for Indonesia, domestic money supply (M1) and term of trades (TOT) for Philippines, foreign interest rate ( R *) for Thailand, and foreign interest rate ( R *) and net foreign assets (NFA) for Singapore, respectively, have the highest significant short-run forcing variable of PPP for countries REERs. Originality/value – In this respect, the outcomes can derive policy implication for the monetary authorities in these ASEAN-5 countries.
