There is a perception that, in the British banks which dominated the industry for much of the twentieth century, management accounting was limited in scope and contributed to a general inefficiency in these institutions. Various official reports published from the 1960s until very recently have reinforced this view. However, some authors have argued that the banks were more sophisticated in their management than such criticisms would imply. This paper investigates the role, development and limitations of management accounting in the sector, drawing on archival evidence and relating this to the more general development of management accounting. In advancing our understanding, evidence is found to support both views.
