From Wikipedia, the free encyclopedia

In monetary economics, redenomination is the process of changing the face value of banknotes and coins in circulation. It may be done because inflation has made the currency unit so small that only large denominations of the currency are in circulation. In such cases the name of the currency may change or the original name may be used with a temporary qualifier such as "new". Redenomination may be done for other reasons such as changing over to a new currency such as the Euro or during decimalisation.

Redenomination itself is considered symbolic as it does not have any impact on a country's exchange rate in relation to other currencies. It may, however, have a psychological impact on the population by suggesting that a period of hyperinflation is over, and is not a reminder of how much inflation has impacted them. The reduction in the number of zeros also improves the image of the country abroad.

Inflation over time is the main cause for the purchasing power of the monetary unit decreasing; but there are a variety of political reasons for the government not reining in inflation or for not redenominating the currency when its value has depreciated significantly. There are some economic and social benefits of redenominating, including improved efficiency in processing routine transactions. Redenomination typically involves the substitution of new banknotes in place of the old ones, which usually cease being legal tender after the end of a short transition period.


In general, redenomination is implemented in response to hyperinflation, which progressively increases the nominal prices of products and services, decreasing the real value of the monetary unit in the local market. Over time, prices become excessively large, which can impede routine 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. Authorities may alleviate this problem by redenomination: introducing a new unit that 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 of redenominations include:

New unit = × Old unit Year
Argentine peso (ARP) = 10 000 Argentine peso ley (ARY) 1983
Argentine austral (ARA) = 1 000 Argentine peso (ARP) 1985
Argentine peso (ARS) = 10 000 Argentine austral (ARA) 1992
New Polish złoty (PLN) = 10 000 old Polish złoty (PLZ) 1995
New Mozambican metical (MZN) = 1 000 old metical (MZM) 2006
Second Zimbabwean dollar (ZWN) = 1 000 first dollar (ZWD) 2006
Third Zimbabwean dollar (ZWR) = 10 000 000 000 second dollar (ZWN) 2008
Fourth Zimbabwean dollar (ZWL) = 1 000 000 000 000 third dollar (ZWR) 2009
This table is not exhaustive.

Although the ratio is often a positive integral power of 10 (i.e., removing some zeros), sometimes it can be a×10n where a is a single-digit integer and n is a positive integer. Partial examples include

New unit = × Old unit Year
German Rentenmark = 1 000 billion Papiermark 1923
Chinese gold yuan = 3 million old yuan 1948
Chinese "silver" yuan [zh] = 500 million Chinese gold yuan 1949
New Taiwan dollar = 40 000 old dollar 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 = × 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
2nd Polish złoty = 1.8 million Polish marka = Swiss franc 1 April 1924
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 which kind of billion or 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 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.[citation needed]

New unit = × Old unit year Nature of the new unit
Turkish new lira = 1 million old lira 2005 "new" is an official designation and was 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.


All countries that previously had currencies based on pounds-shillings-pence (£sd) system (£1 = 20 shillings = 240 pence) have now adopted decimal currencies (currencies related by powers of 10), with several changing the name of the main currency unit at the same time. As of 2020, only two currencies are non-decimal, being the Mauritanian ouguiya and Malagasy ariary, with one of each divided into five subdivisory units.

Currency union[edit]

When countries form a currency 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

List of Euro redenominations[edit]

The most notable currency union today is the Eurozone. In 2002, euros in cash form were introduced.

Japanese invasion money suffered from heavy inflation. At the end of World War II governments of liberated countries and territories opted to simply declare them worthless.

In 2016, the Colombian peso was rated at around 3,000 per U.S. dollar, with banknotes up to 50,000 pesos. Instead of redenominating the currency, a new banknote design was introduced, with the last three zeroes replaced by the word "mil" (thousand), making the values easier to read.
