Regulatory foundations of financialisation: May Day, Big Bang and international banking, 1975–1990

From the 1970s to the 1990s there was a revolution in international financial markets, which combined the processes of financialisation and globalisation. Deregulation and financial innovation were the two underlying forces that facilitated this transformation. At the same time, distinctive national characteristics of banking structures and cultures influenced the way that financial globalisation affected the geographic distribution of financial activity. This article addresses these seismic shifts through three perspectives: changes in regulation and the geographic pattern of international banking activity, reform of the main stock markets in New York and London and the rise of financial conglomerates. It identifies complementarity as well as competition among international financial centres.
