The '''Brunei dollar''' (sign: '''B$''', [[Social:Malay language|Malay]]: ''ringgit Brunei'', [[ISO 4217|currency code]]: ''BND''), has been the [[Finance:Currency|currency]] of the Sultanate of Brunei since 1967. It is normally abbreviated with the [[Finance:Dollar sign|dollar sign]] '''$''', or alternatively '''B$''' to distinguish it from other dollar-denominated currencies. It is divided into 100 ''sen'' (Malay) or ''[[Finance:Cent (currency)|cents]]'' (English). The Brunei dollar is issued by the Brunei Darussalam Central Bank.

Under a Currency Interchangeability Agreement in 1967, the Brunei dollar is interchangeable with the [[Finance:Singapore dollar|Singapore dollar]] at par. As such, the Brunei dollar is accepted in Singapore as "customary tender"; likewise, the Singapore dollar is accepted  in Brunei.<ref name="Monetary Authority of Singapore">{{Cite web |last=Monetary Authority of Singapore |title=The Currency Interchangeability Agreement |url=http://www.mas.gov.sg/en/Currency/Currency-Interchangeability-Agreement-with-Brunei.aspx |url-status=dead |archive-url=https://web.archive.org/web/20121025000510/http://www.mas.gov.sg/en/Currency/Currency-Interchangeability-Agreement-with-Brunei.aspx |archive-date=25 October 2012 |access-date=23 October 2012}}</ref>

==History==


Early currency in Brunei included [[Biology:Cowrie|cowrie]] shells. Brunei is also famous for its bronze teapots, which were used as currency in barter trade along the coast of northern Borneo. The Spanish-American silver dollar brought over by the Manila galleons was in wide use for Brunei's international trade from the 16th to 19th centuries; the 19th century Straits dollar was itself derived from the same coin.

Brunei issued [[Chemistry:Tin|tin]] coins denominated in pitis in [[Engineering:Islamic calendar|AH]]1285 (AD1868). These were followed by a one cent coin in [[Engineering:Islamic calendar|AH]]1304 (AD1888). This cent was one hundredth of a Straits dollar.

As a protectorate of {{wipe|United Kingdom}} in the early 20th century, Brunei used the Straits dollar from 1906, the Malayan dollar from 1939 and the Malaya and British Borneo dollar from 1953 until 1967, when it began issuing its own currency.

The Brunei dollar replaced the Malaya and British Borneo dollar in 1967 after the formation of Malaysia and the independence of [[Place:Singapore|Singapore]]. Until 23 June 1973, the [[Finance:Malaysian ringgit|Malaysian ringgit]] was exchangeable at par with the Singapore dollar and Brunei dollar. The Monetary Authority of Singapore and the Brunei Currency and Monetary Board (now the Authoriti Monetari Brunei Darussalam (Monetary Authority of Brunei Darussalam)) still maintain the exchangeability of their two currencies. The dollar is accepted as "customary tender" in Singapore according to the Currency Interchangeability Agreement,<ref name="Monetary Authority of Singapore" /> although it is not legal tender there.

===History of coins used in Brunei===
Coins were used in Brunei from the 10th century. The Straits dollar was also used in Brunei from 1906.

Due to the close ties between {{wipe|China}} and Brunei, the first type of coins used in Brunei were Chinese coins. This was initially called ‘Pitis’. They were later known as ‘Kue’ when local ‘Pitis’ were introduced.<ref name="Star">{{Cite web |title=Brunei History seen through its coinage |url=http://www.bt.com.bn/features/2007/08/12/brunei_history_seen_through_its_coinage |url-status=dead |archive-url=https://web.archive.org/web/20120722215741/http://www.bt.com.bn/features/2007/08/12/brunei_history_seen_through_its_coinage |archive-date=22 July 2012 |access-date=25 January 2012 |publisher=Brunei Times}}</ref><ref name="Coinage">{{Cite web |title=Brunei's currency notes before 1967 |url=http://www.bt.com.bn/classification/life/2007/06/30/bruneis_currency_notes_before_1967 |url-status=dead |archive-url=https://web.archive.org/web/20140108170730/http://www.bt.com.bn/classification/life/2007/06/30/bruneis_currency_notes_before_1967 |archive-date=8 January 2014 |access-date=2 September 2013 |df=dmy-all}}</ref> The local ‘Pitis’ coins had ‘Sultanate of Brunei’ stamped in front of the coin and the royal umbrella was imprinted at the back. These were issued from the 16th to the 19th century. Previous Islamic coins were also called the ‘Pitis’.<ref name="Bk2" /> Another type of coin that was used in Brunei were ‘Duit besi’ (which roughly translates to ‘Iron money’). Iron was considered valuable those days that it was used as money. 100 one-square inch pieces were valued at 1 dollar.<ref name="Coinage" />

The last coin to be issued before the introduction of the Straits Settlements currency was the ‘Duit Bintang’, otherwise known as the ‘Star coin’ or the 'Star Cent'.<ref name="Star" /> It is called the Star coin because of the star imprinted on the obverse of the coin. It was minted in Birmingham, {{wipe|England}}, in 1887.<ref name="Star" /> It was made from [[Chemistry:Copper|copper]].

With the introduction of the Straits Settlements currency, the previously used coins were taken out of circulation. They were, however still used with certain exchange rates.<ref name="Coinage" />

Prior to 1984, the coins were made by the Royal Mint of the {{wipe|United Kingdom}}.<ref name=":4">{{Cite news |date=29 August 1984 |title=Brunei using S'pore-made coins for the first time |pages=2 |work=Singapore Monitor |url=https://eresources.nlb.gov.sg/newspapers/Digitised/Article/singmonitor19840829-1.2.6.3 |access-date=25 May 2023}}</ref>

In 1984, Brunei Currency Board ordered four million circulation coins from the Singapore Mint.<ref name=":4" /> The circulation coins consisted of one cent coint in bronze and five, ten, twenty and fifty cents coins in cupro-nickel.<ref name=":4" /> The 50 cents has an additional security feature with a reeded edge with dots between lines at regular interval while other countries' circulation coins are mill-edged.<ref name=":4" />

===History of banknotes used in Brunei===

[[File:Straits Settlements - 1935 - $1 banknote (obverse).jpg|thumb|right|One Straits dollar banknote from 1935]]
The Straits dollar was introduced in Brunei in 1906. It was later replaced by the Malayan dollar which was introduced to British colonies and Brunei in 1939. It replaced the Straits dollar at par with a 1:1 exchange rate. The Malayan dollar was issued by the Board of Commissioners of Currency, Malaya. The board stopped issuing the Malayan dollar during the {{wipe|Japan}}ese invasion during [[Social:World War II|World War II]]. The Malayan dollar had the portrait of King George VI in front of the note.<ref name="Star" />

In 1952, the board was renamed the Board of Commissioners of Currency, Malaya and British Borneo. The board then began to issue notes to Malaya, [[Place:Singapore|Singapore]], Sarawak, British North Borneo, and Brunei in 1953. This was known as the Malaya and British Borneo dollar.<ref name="Star" /> 
In 1967, the Malaya and British Borneo dollar was replaced by three new currencies: the Malaysian dollar, [[Finance:Singapore dollar|Singapore dollar]] and the Brunei dollar, all at par.<ref name="Bk">{{Cite book |title=Basic Commerce for Brunei Darussalam |pages=22}}</ref> The Interchangeability Agreement which the three countries adhered to as original members of the currency union meant the Brunei dollar was exchangeable at par with the Singapore dollar and Malaysian dollar. This ended on 8 May 1973, when the Malaysian government withdrew from the agreement.<ref name="Interchangeability Agreement">{{cite web

The currencies of the 3 countries were interchangeable at par value under the Interchangeability Agreement until 8 May 1973 when the Malaysian government decided to terminate it. Brunei and Singapore however continue with the Agreement until the present day.

==Coins==


In 1967, coins were introduced in denominations of 1, 5, 10, 20 and 50 cents. Except for the bronze 1 cent, the coins were struck in cupro-nickel. 

In 1986, copper-clad steel replaced bronze.<ref>[http://www.finance.gov.bn/tt/EDITKKW/bcb/coins_cir_2nd.htm Ministry of Finance<!-- Bot generated title -->] {{webarchive|url=https://web.archive.org/web/20080315044719/http://www.finance.gov.bn/tt/EDITKKW/bcb/coins_cir_2nd.htm|date=15 March 2008}}</ref> Later, in 2008, the 1 cent coins switched compositions to brass.

==Banknotes==

On 12 June 1967,<ref>{{Cite book |last=Linzmayer |first=Owen |url=http://www.banknotebook.com |title=The Banknote Book |publisher=www.BanknoteNews.com |year=2011 |location=San Francisco, CA |chapter=Brunei |access-date=21 August 2011 |archive-url=https://web.archive.org/web/20150923031410/http://www.banknotebook.com/ |archive-date=23 September 2015 |url-status=live}}</ref> the government (''Kerajaan Brunei'') introduced notes in denominations of 1, 5, 10, 50 and 100 dollars. Notes for 500 and 1,000 dollars followed in 1979. In 1989, the title on the paper money was changed to ''Negara Brunei Darussalam'', the official name of the country, and the Malay term for “State of Brunei, Abode of Peace.” 10,000 dollar notes were introduced the same year. All notes bear the denomination in Malay (in both Rumi and Jawi) and in English. The English denomination appeared on the obverse below the denomination in Malay on the earlier series, but now appears on the reverse together with the Jawi.

Five series of notes have been issued. The colours of $1, $5, and $10 notes have been the same for all the series of banknotes. [https://web.archive.org/web/20041218033554/http://www.finance.gov.bn/tt/EDITKKW/bcb/notes_cir_2nd.htm]
