This is a detailed case study of the IMF, which Strange uses to back up her warning that there can be no justification for an analytical division between the economic and the political. She argues that the IMF can only be understood within its international political context, and suggests that any institutional changes will reflect the continuing development of the international economy. It is important to recognise that the US is its chief initiator of policy and influence, both directly through its constitutionally predominant position in the organisation and through its wider impact on the international environment in which the IMF operates. Although not a full argument for structural power, this article recognises that relational power is insufficient to fully explain power relations within the IMF.
