International monetary and financial crises have punctuated US hegemony since 1945. With US hegemony likely to endure and crises likely to recur, we need to understand how the US reacts to such events: benevolently or exploitatively? Using a case study of US behaviour during the 1969-76 international monetary crisis, this thesis challenges narratives that interpret events in terms of the concentration or deconcentration of power in the US hegemon, and favours an explanation of US behaviours based on the interplay of US domestic politics and international security imperatives. Using a Constructivist definition of hegemony and a neoclassical realist theoretical framework, I analyse the crisis from the perspectives of the international monetary order and system, respectively. I introduce a novel division of Strange’s concept of structural power into its negative and positive components (the power to disrupt or create international structures, respectively). Using these analytical tools, I analyse documents held in the UK and US National archives, President Nixon’s White House tapes and the Bank of England archive. Key and original findings include: - US tactics veered between hegemony by consent and, when that failed to yield the desired results, hegemony through domination; - domination tactics could be brutal, as when President Nixon and his National Security Advisor, Kissinger, tried to wreck European integration by destroying its first attempt at monetary union. Their intention was to advance the US’ security agenda by weakening EEC states; - Kissinger intervened in the Committee of Twenty’s negotiations to delay agreement on international monetary reform (despite the US being on the verge of achieving its objectives) until European states had acceded to what he wanted on security in the “Year of Europe” negotiations. Delay killed US plans to return to fixed exchange rates; - hegemonic stability theory-based explanations of events are challenged by the US terminating its Bretton Woods regime, persuading follower states to introduce generalised floating and blocking international monetary reform; - structural Realist and Marxist narratives of the crisis are challenged, inter alia, by President Ford abandoning Nixon’s attempts to strengthen US hegemony in favour of a laissez-faire solution to the international monetary crisis; - the decisions creating the basis of a neoliberal international monetary order (the introduction of floating exchange rates and free capital mobility) were taken for US international security or domestic political reasons, as neoclassical realism theory would predict. These decisions had profound economic consequences, but were not taken for economic reasons.

O futuro das relações monetárias entre países é incerto. Enquanto a economia mundial há tempos tem contado com uma moeda internacional dominante, com o seu emissor desempenhando o papel de líder monetário internacional, existe uma série de fatores que coloca em cheque a continuação desse arranjo. Entre esses fatores estão a diminuição do papel dos Estados Unidos no crescimento econômico mundial, a crescente autonomia das políticas monetárias dos países emergentes e em desenvolvimento e a emergência de possíveis desafios ao dólar americano como a moeda chave de reserva internacional. A situação se apresenta por meio de um dilema quanto ao potencial futuro de um processo de cooperação monetária. Essencialmente, na ausência de um sistema hegemônico respaldado por um poder estrutural, como os países concordarão em ajustes mútuos adequados? Com essa questão em mente, esse estudo começa discutindo a cooperação monetária entre países e examina o papel do poder produtivo na coordenação de políticas. Por fim, o estudo procura testar as condições que permitem que os países designam responsabilidade por ajustes de política por meio da aplicação de tal poder. / The future of international monetary relations is uncertain. While the world economy has long relied on a dominant international currency, with its emitter playing the role of international monetary leader, there are several factors that place the continuance of this arrangement into doubt. Amongst these factors is the diminishing role of the U.S. economy in global output, the enhanced monetary policy autonomy of emerging market and developing economies, and the emergence of possible challengers to the U.S. dollar for the position of key international reserve currency. This situation presents us with a dilemma as to the future potential for monetary cooperation. Essentially, in the absence of a systemic hegemon, backed by structural power, how will countries come to agree on proper mutual adjustments? With this question in mind, this paper begins by discussing international monetary cooperation and examines the role of productive power in policy coordination. Finally, the paper looks to test for the conditions that allow for countries to assign responsibility for policy adjustments via the application of such power.
