# Redenomination

Redenomination is the process of changing the face value of banknotes or coins used in circulating currency.

When redenomination occurs, financial data that spans the change must be correctly accounted for. For example, the GDP reported by the Central Bank of Nicaragua is properly documented.

## Inflationary

In times of inflation, the same number of monetary units have continually decreasing purchasing power. In other words, prices of products and services must be expressed in higher numbers. If these numbers become excessively large, they can impede daily transactions because of the risk and inconvenience of carrying stacks of bills, or the strain on systems, e.g. automatic teller machines (ATMs), or because human psychology does not handle large numbers well. The authorities may alleviate this problem by redenomination: a new unit replaces the old unit with a fixed number of old units being converted to 1 new unit. If inflation is the reason for redenomination, this ratio is much larger than 1, usually a positive integral power of 10 like 100, 1000 or 1 million, and the procedure can be referred to as "cutting zeroes".[1] Recent examples include

New unit = x Old unit year
Fourth Zimbabwean dollar (ZWL) = 1 000 000 000 000 ZWR February 2009
Third Zimbabwean dollar (ZWR) = 10 000 000 000 ZWN August 2008
Second Zimbabwean dollar (ZWN) = 1 000 ZWD (first dollar) August 2006
New Mozambican metical = 1 000 old meticais 2006
This table is not exhaustive.

Although the ratio is often a positive integral power of 10, sometimes it can be a×10n where a is a single digit integer and n is a positive integer. Partial examples include

New unit = x Old unit year
Rentenmark = 1 000 billion Papiermark 1923
Chinese "gold" yuan = 3 million old yuan 1948
Chinese "silver" yuan = 500 million "gold" yuan 1949
New Taiwan dollar = 40 000 old dollars 1949
Azerbaijani new manat = 5 000 old manat 2006
This table is not exhaustive.

Occasionally, the ratio is defined in a way such that the new unit is equal to a hard currency. As a result, the ratio may not be based on an integer. Examples include

New unit = x Old unit = Anchor currency year
Brazilian real = 2 750 cruzeiros reais = United States dollar 1 July 1994
Yugoslav novi dinar = 10~13 million 1994 dinara = Deutsche Mark 24 January 1994
This table is not exhaustive.

In the case of hyperinflation, the ratio can go as high as millions or billions, to a point where scientific notation is used for clarity or long and short scales are mentioned to disambiguate what kind of billion/trillion is meant.

In the case of chronic inflation which is expected to continue, the authorities have a choice between a large redenomination ratio and a small redenomination ratio. If a small ratio is used, another redenomination may soon be required, which will entail costs in the financial, accounting, and computing industries. However a large ratio may result in inconveniently large or small prices at some point in the cycle.

After a redenomination, the new unit is often has the same name as the old unit, with the addition of the word "new". The word "new" may or may not be dropped a few years after the change. Sometimes the new unit is a completely new name, or a "recycled" name from previous redenomination or from ancient times.

New unit = x Old unit year Nature of the new unit
Turkish new lira = 1 million old lira 2005 "new" is an official designation and has been dropped in 2009.
New Taiwan dollar = 40 000 old dollars 1949 "new" is an official designation and is still used in official documents today
Argentine austral = 1 000 Peso argentino 1985 completely new name
Yugoslav 1993 dinar = 1 million 1992 dinara 1993 no official designation
Brazilian real = 2 750 cruzeiros reais 1994 recycled unit of Brazil before 1942
This table is not exhaustive.

## Monetary union

When countries form a monetary union, redenomination may be required. The conversion ratio is often not a round number, and may be less than 1.

New unit = x Old unit year Monetary union
Danish krone = 0.5 Danish rigsdaler 1873 Scandinavian Monetary Union
Gulden österreichischer Währung = 20/21 Gulden Conventions-Münze 1858 Wiener Münzvertrag between the states of the German Customs Union and the Austrian Empire
Euro = 0.787564 Irish pound 1999/2002 Eurozone
Euro = 40.3399 Belgian or Luxembourgian francs 1999/2002 Eurozone
This table is not exhaustive.

## Decimalisation

The currency was decimalised in all countries where a pounds-shillings-pence £sd system (£1 = 20 shillings = 240 pence) was previously used. Several countries chose to change the main currency unit at the same time. By defining 1 dollar = £0.5 = 100 cents, 1 shilling would conveniently turn into 10 cents.

New unit = x Old unit year
German gold mark = 1/3 Vereinsthaler 1873
(New) Penny = 2.4 Penny 1971
South African rand = 0.5 South African pound 1961
Australian dollar = 0.5 Australian pound 1966
New Zealand dollar = 0.5 New Zealand pound 1967
This table is not exhaustive.
