TheBank of England £100,000,000 note, also referred to asTitan, is a non-circulatingBank of Englandsterlingbanknote used to back the value ofScottish andNorthern Irish banknotes. It is the highest denomination of banknote printed by the Bank of England. As bothScotland andNorthern Ireland have banknotes issued by particular local banks, the non-circulating notes provide the essential link between those banknotes and the currency ofEngland and Wales, and security if a local issuing bank were to fail.
The £100 million note (nicknamed "Titan" simply because of its titanic value) backs the value of common circulating notes (£1, £5, £10, £20, £50, and £100 notes) issued by the sixcommercial banks inScotland (Bank of Scotland,Royal Bank of Scotland,Clydesdale Bank) andNorthern Ireland (Bank of Ireland,Danske Bank andUlster Bank). Themillion pound note plays a similar vital role in the British currency system.[1][2][note 1] Scottish and Northern Irish banknotes are often viewed with suspicion by businesses inEngland andWales as businesses are not always familiar with the different types of notes that are issued and may not be sure on how to check them forcounterfeiting and, therefore, do not like to accept them.[3] The backing by the £100 million notes and the £1 million notes is intended to maintain public confidence in the value the notes represent. For every pound an authorised Scottish or Northern Irish commercial bank prints and issues in the form of its own notes, it must deposit the equivalent in pound sterling with the Bank of England. If necessary, notes from a struggling Scottish or Northern Irish commercial bank could be replaced with regular Bank of England issued cash.[1][note 2]
The Bank of England prints £100 million notes internally, rather than at its normal commercial printers, for security reasons. The £100 million notes are then locked away together with other backing assets either within the Bank of England vault, or in other authorised locations, to further ensure their security as physical assets.[1][4] For even further security, £100 million notes must be signed by the existing Chief Cashier in order to become legal tender and actually be used as a backing asset for commercial banks and their notes in Scotland and Northern Ireland.[4][5]
