The implementation of the European System of National and Regional Accounts 1995 (ESA 95) at end-September 1997 resulted in the Channel Islands and the Isle of Man being treated as non-residents for statistical purposes. Following the Green Paper on Monetary Control in 1980, the islands banks had the option either to be part of the UK banking sector, or to remain outside as Other (UK) Financial Institutions (OFIs). So, prior to September 1997, some of the islands’ banking business was included in the M4 family of data, and some in domestic borrowing and lending in the National and Financial Accounts. 

Monetary Financial Institutions (MFIs) are banks and building societies (building societies comprise branches of UK building societies and appropriate territorial corporations.
