Abstract

The abrupt separation of Singapore and Malaysia in 1965 set these two states on separate political trajectories, but the economic ties proved more difficult to untangle. This article explores the nine years of transition required to complete the separation of the monetary systems of the two territories based on new archival evidence. It argues that, while socio-political hostility raged between the two partners, common economic interests prolonged an intimate monetary relationship that extended the interdependence of the two states for many years beyond their formal separation.
