"The crisis of 2007–9 has cast fresh light on the ascendancy of finance in recent years, a process that is often described as financialization. The concept of financialisation has emerged within Marxist political economy in an effort to relate booming finance to poorly performing production. Yet, there is no general agreement on what it means, as is shown in this article through a selective review of economic and sociological literature. The article puts forth an analysis of financialization that draws on classical Marxism while remaining mindful of the recent crisis. Financialization represents a systemic transformation of mature capitalist economies with three interrelated features. First, large corporations rely less on banks and have acquired financial capacities; second, banks have shifted their activities toward mediating in open financial markets and transacting with households; third, households have become increasingly involved in the operations of finance. The sources of capitalist profit have also changed accordingly."
