Financialization (or financialisation in British English) is a term sometimes used to describe the development of financial capitalism during the period from 1980 to present, in which debt-to-equity ratios increased and financial services accounted for an increasing share of national income relative to other sectors.
Financialization describes an economic process by which exchange is facilitated through the intermediation of financial instruments. Financialization may permit real goods, services, and risks to be readily exchangeable for currency, and thus make it easier for people to rationalize their assets and income flows.
Financialization is tied to the transition from an industrial economy to a service economy, as financial services belong to the tertiary sector of the economy.
