Most commentators on the 1949 sterling crisis have viewed it as an episode with implications merely for the management of the British economy. This paper, based on the public records now available, discusses the impact of the crisis on British economic foreign policy. In particular it suggests that the crisis revealed deep Anglo-American differences, centring on the nature of the Marshall Plan, on the international value of the sterling area, and on the proper relationship between the United Kingdom and Western Europe, Ultimately the British succeeded in resolving these disagreements: but this triumph ironically implied both the defeat of British aims in post-war European reconstruction and a long term delusion that great power status could be maintained on the basis of a special relationship-with the United States.
