Most notably, major building societies, such as the Abbey National and Halifax, have taken advantage of changes introduced by the BUILDING SOCIETIES ACT 1986 and the FINANCIAL SERVICES ACT 1986 and have converted themselves into public JOINT-STOCK COMPANIES, setting themselves up as ‘financial supermarkets’ offering customers a banking service and a wide range of personal financial products, including insurance, personal pensions, unit trusts, individual savings accounts (ISAs), etc. This development has introduced a powerful new competitive impetus into the financial services industry, breaking down traditional ‘demarcation’ boundaries in respect of ‘who does what’, allowing former building societies to ‘cross-sell’ these services and products in competition with traditional providers such as the COMMERCIAL BANKS, INSURANCE COMPANIES, UNIT TRUSTS, etc.
Building society deposits constitute an important source of liquidity in the economy and count as ‘broad money’ in the specification of the MONEY SUPPLY. See FINANCIAL SYSTEM.
