This chapter investigates the offshore revolution through Lloyd’s of London, an insurance firm based in the City of London, instrumental to the formation of financial petroculture. Lloyd’s took on its globally significant role because of a convergence of economic, political, infrastructural and architectural shifts. In this chapter, I trace that conjuncture as a prehistory of our volatile present, before finance gets resignified as a driver of climate catastrophe. Tracing this financial offshoring through the development of the Lloyd’s Building between 1978 and 1986, I use it to frame the convergence of finance, oil, and neoliberalism in the United Kingdom, as a way of thinking through financial centres as petrocultures.
