Mauritius



Political sketch

Formerly Île de France. Independent from the United Kingdom on 12 March 1968.

Mauritius was long a station on the shipping route from Europe to the Indies around the Cape of Good Hope. The Dutch were the first people to try to settle Mauritius (which they named after prince Maurice of Nassau), but they abandoned it after attempts of 1638-1658 and 1664-1710. On 20 September 1715 the French East India Company (Compagnie des Indes) occupied Mauritius, which it renamed Île de France; the French government took over administration in 1767. Sugar planting was the main industry, and the colony prospered. During the wars between United Kingdom and France, Île de France was a threat to British shipping. In 1810 the British captured the island, and kept it under the terms of the Treaty of Paris in 1814. The customs, laws, and language remained French, but the name Mauritius was reinstated. The British abolished slavery in 1835 and the slaves were replaced by Indian laborers. In the late 1800s Mauritius declined because of competition from beet sugar, a malaria epidemic in 1866-68, and the opening of the Suez Canal in 1869. The Suez Canal provided a more direct shipping route from Europe to the Indies. During the First World War, sugar prices rose and the economy prospered, but the economy went into depression in the 1930s, leading to labor unrest in 1937. Mauritius became from the United Kingdom on 12 March 1968. After independence, Mauritius initiated a successful program to develop a textile export industry; it has since moved into more sophisticated industries and tourism to further diversify the economy. Mauritius has remained democratic since independence.



Wars since 1500

Napoleonic Wars, 1810; Second World War, 1939-1945 (no battles, but affected by danger to shipping; also, Mauritius involved as a launching point for the British invasion of Madagascar).



Convertibility

The sterling area:

On 2 August 1914, soon after the First World War began, the United Kingdom issued a proclamation imposing a one-month moratorium of payment for bills of exchange accepted before 4 August; an act of 3 August 1914 gave legislative sanction to the proclamation. The moratorium was subsequently extended for a month and ended on 4 November 1914. Legally the pound sterling remained convertible into gold and could be exported, but the risk to shipping from German submarines made the cost of shipment prohibitive, so the United Kingdom was in effect off the gold standard. The British government refused to include private shipments of gold in its war-risk insurance scheme. After the war, the export of gold was prohibited from 1 April 1919 under regulations that were given statutory form in 1920. On 28 April 1925 the government announced that the act would not be renewed when it expired on 31 December 1925. On 13 May 1925 the United Kingdom resumed the gold standard.

The United Kingdom abandoned the gold standard on 21 September 1931. The currencies of British colonies were almost all linked to the pound sterling through currency boards; being on a sterling-exchange standard rather than a gold-exchange standard, they followed the pound sterling off gold. Over the next few years, some former British colonies (Australia, New Zealand, South Africa) and other countries that had important trade links with the United Kingdom switched from gold to the pound sterling as their official or actual anchor. The result was termed the sterling area. The United Kingdom imposed exchange controls on 4 September 1939, the day after entering the Second World War. Most countries that were not current or former British colonies soon left the sterling area. Among the remaining countries, both current- and capital-account transactions were free of restrictions within the sterling area, but were restricted in dealings with outside countries. After the Second World War, the United Kingdom returned to the gold standard under the Bretton Woods system. It removed exchange controls on 15 August 1947, but reimposed them on 20 August 1947 after suffering a large loss of foreign reserves. Sterling had a dual exchange rate from 1961 until the United Kingdom abolished exchange controls. The sterling area remained in existence because sterling was not fully convertible. It began to crumble after the United Kingdom again abandoned the gold standard on 23 June 1972. By January 1973 the sterling area had shrunk to the British Isles and a few small British colonies; even Hong Kong had abandoned sterling as its anchor currency. The United Kingdom abolished exchange controls on 24 October 1979, ending the sterling area.

Mauritius alone:

Mauritius left the sterling area on 23 June 1972.

Its notes were called récépissés de la Compagnie des Indes (East India Company receipts, issued from 1719-1729), billets de boutique (store currency, issued 1736), and billets de caisse (cash notes, issued in 1737, 1741, and 1761). The first coins were issued by the company in 1723 for Mauritius and Réunion jointly.

The company's notes had depreciated to one-third of their face value. Government notes were issued in 1766, July 1768, September 1771-1772, and June 1778 (Mazard 1953: 41; Zay 1892: 254). Leduc (1965: 40) also mentioned an issue of 1775.

Notes were almost not used after October 1795. There was an unsuccessful attempt in 1796 to issue a new currency supposedly based on tax revenue, mandats gagés sur les impositions, but it was unsuccessful.

A new governor withdrew government notes at a rate of 2,000 local paper livres = Spanish silver $1 shortly after arriving in 1803.

free banking one note-issuing bank Mauritius Commercial Bank Limited (1963: 4) The Bank of Mauritius (headquarters Port Louis, Mauritius) opened in Port Louis. It was the first bank in Mauritius. It was familiarly known simply as the Bank of Mauritius. Details of its operations are scarce. Apparently stockholders had unlimited liability. I classify this as an episode of free banking because although only one bank existed, there were apparently no strong legal barriers to establishing rivals.

It was the first bank to be durable. The second bank to be durable, the Mauritius Commercial Bank (headquarters Port Louis, Mauritius), opened in Port Louis on 1 September 1838 (Mauritius Commercial Bank 1963: 7). (The authorizing legislation was Mauritius, proclamation of 6 July 1838, reprinted in Mauritius Commercial Bank 1963: Appendix II). The other bank to issue notes was the Bank of Agriculture (headquarters Port Louis, Mauritius). The government issued $1 notes through the banks to remedy a shortage of coins (Mauritius, Ordinance No. 10 of 1842, cited in [Lagesse 1988?]); the banks were prohibited from issuing notes under $5.

The Commissioners of Currency issued both small-denomination silver notes and large-denomination gold notes through 31 December 1877; then they ceased issuing gold notes (Mauritius, Ordinance No. 28 of 1876). It is not clear from my sources whether the currency board-like authority also had responsibility for issuing coins in this period.

The currency board apparently issued coins as well as notes. The margins the currency board maintained were originally a very wide +/-3.5% around the central rate, falling over time to +/-0.5% (Mauritius Commercial Bank 1963: 2).

fixed (as part of a currency union with Réunion), 1.5 French colonial livres = 1 French livre (livre tournois) (Mazard 1953: 40-1) In practice, often a clean? float. This was the period of French rule. France minted general issues of small-denomination coins (deniers) for its colonies in 1721 and 1722. Chalmers (1893: 361) says that "the real metallic standard of the 18th century was the Spanish [silver] dollar," also known as the piastre. Notes often circulated at a discount to gold and silver coins. By 1800 the local livre, nominally 10 colonial livres = Spanish silver $1, had depreciated to 10,000 local paper livres = $1. A new governor withdrew government notes at a rate of 2,000 local paper livres = Spanish silver $1 shortly after arriving in 1803.

The ratings established in 1810 undervalued the Spanish silver dollar relative to the Indian rupee and resulted in importation of silver rupee coins.

The Mauritius dollar was a decimal currency by this time, implies one source, though another sources places decimalization at 1876. The government withdrew its notes from circulation at the end of the period. The name for the currency came from the widely used Spanish dollar.

-31 August 1849

fixed; Mauritius $5 = UK£1 Mauritius, Ordinance No. 3, 25 November 1825, cited in Chalmers (1893: 364) The Mauritius dollar was the principal unit of account in practice, although the pound sterling was the official unit of account and Indian rupees were widely used in trade. By convention at the time, Mauritius $1 = 2 Indian sicca (Calcutta) rupees = UK 2 shillings (24 pence), though by law 2 rupees were only worth UK 1 shilling 10 pence (22 pence). Sterling coins predominated from about 1851 until the early 1860s as a result of the depreciation of gold against silver; Indian coins came back in early 1860s as gold appreciated. Mauritius was hence awkwardly caught between the gold and silver standards for the second half of this period.

The Mauritian rupee replaced the Mauritius dollar as the unit of account at a conventional rate of 2 Mauritian rupees = Mauritius $1. The Indian rupee was a silver currency at the start of this period, but on 26 June 1893 it began a transition to a gold basis. Indian government notes later became legal tender in Mauritius (Mauritius, Ordinance No. 30, published 31 July 1920, cited in [Lagesse 1988? Alluded to in Mauritius Commercial Bank 1963: 2]). The name for the currency came from the Indian rupee.

So, the exchange rate may in practice have been a band initially. Switched to the pound sterling as the anchor currency, at the prevailing cross rate with Indian rupee. This was a transition from the silver to the gold zone. Indian notes ceased to be legal tender on 1 January 1939 (Mauritius, Notice No. 39, 26 November 1938, cited in [Lagesse?]).

pegged, dual rate; official rate 13-1/3 Mauritian rupees = UK£1 consequence of Mauritius, Bank of Mauritius Ordinance, 28 September 1966, cited in Bank of Mauritius annual report, June 1968: 1 Certain capital transfers to countries outside the sterling area were channeled through the "investment currency" market in the United Kingdom,which had a floating exchange rate (IMF ARER 1969: 320, 483). Indirectly, then, there was a third exchange rate. Because it was only indirect, I count the exchange rate as dual. At independence, Mauritius took over the administration of exchange control from the United Kingdom. The dual exchange rate replaced an "indirect" dual exchange rate that had previously existed under British rule because the pound sterling had a dual rate. There was a stamp duty on capital transfers, initially 15%; later the rate was raised and lowered at various times. Gold convertibility for all countries ended in practice when the United States abandoned the gold standard on 15 August 1971. Mauritius had not yet established a gold parity. The official exchange rate with the US dollar was 1 Mauritian rupee = US$0.18, or 5.55555 Mauritian rupees = US$1 (IMF ARER 1972: 297).

This occurred shortly after the United States devalued the US dollar against gold on 18 December 1971. The second exchange rate was the stamp duty rate for capital transfers.

The pound sterling continued to be the anchor currency even after the United Kingdom floated it against gold and the US dollar on 23 June 1972.

Band width +/-2% until May 1982, +/-5% from June 1982. Devalued. The previous rate of 10 Mauritian rupees = 1 SDR continued to apply to government imports of rice and flour. The stamp duty on transfers of capital also continued.

flexible basket, dual rate Bank of Mauritius, press communiqué of 28 February 1983, reprinted in Bank of Mauritius annual report, June 1983: 57 RR: Small parallel market premium, never exceeding low double digits and then only for a few months. De facto crawling band around US dollar. Band width +/-5% to either November 1992 or January 1993 (RR apparently made a typographical error here), +/-2% thereafter. Switched to a trade-weighted basket of the currencies of major trading partners as the anchor. The government did not disclose the composition of the basket. The change in exchange rate policy was part of a broad financial liberalization.

independent float IMF ARER (1999: 566) RR: Small parallel market premium, never exceeding low double digits and then only for a few months, until data end in December 1998.
