The institutions, services and products that comprise the financial services sector vary from country to country, but generally include the central bank; depository organizations such as banks, building societies or mortgage banks and companies; credit unions or credit cooperatives; insurance and pension funds; general financiers; cash management firms; and other engaged in financial intermediation or asset management. Financial intermediaries may themselves include securitizers, investment firms, leasing companies, hire purchase and the provision of personal and consumer credit. In some cases, a broader perspective of the financial services sector needs to incorporate not only the financial industry but also the business services that support its operation.
