The '''baht''' ({{IPAc-en|b|ɑː|t}}; {{lang-th|บาท}}, {{IPA-th|bàːt|pron}}; sign: '''฿'''; [[ISO 4217|code]]: '''THB''') is the official [[Finance:Currency|currency]] of Thailand. It can be divided into 100 ''satang'' ({{lang|th|สตางค์}}, {{IPA-th|sà.tāːŋ|pron}}). The issuance of currency is the responsibility of the Bank of Thailand. [[Organization:Society for Worldwide Interbank Financial Telecommunication|SWIFT]] ranked the Thai baht as the 10th-most-frequently used world payment currency as of December 2023.<ref>[https://www.swift.com/file/58686/download?token=4V_STiPJ] {{Webarchive|url=https://web.archive.org/web/20190422163705/https://www.swift.com/file/58686/download?token=4V_STiPJ|date=2019-04-22}}[https://www.swift.com/file/56351/download?token=pg_59sd1 RMB Tracker February 2019] {{Webarchive|url=https://web.archive.org/web/20190422163642/https://www.swift.com/file/56351/download?token=pg_59sd1|date=2019-04-22}}</ref>

== History ==

The Thai baht, like the pound, originated from a traditional unit of [[Physics:Mass|mass]]. Its currency value was originally expressed as that of [[Chemistry:Silver|silver]] of corresponding weight (now defined as 15 grams), and was in use probably as early as the [[History:Sukhothai Kingdom|Sukhothai]] period in the form of bullet coins known in Thai as ''phot duang''.<ref>{{cite web |title=Thailand Commemorative Bullet Coins (112) |url=https://coincoin.com/I112.htm |website=Scott Semans World Coins |access-date=25 October 2018 |archive-url=https://web.archive.org/web/20171111111216/http://www.coincoin.com/I112.htm |archive-date=11 November 2017 |url-status=dead }}</ref> These were pieces of solid silver cast to various weights corresponding to a [[Physics:Thai units of measurement|traditional system of units]] related by simple fractions and multiples, one of which is the ''baht''. These are listed in the following table:<ref>{{cite web |url=http://www.chiangmai-chiangrai.com/siamese_money.html |title= The History of Siamese Money |access-date=2018-10-25|date=2010-06-16|website= Welcome to Chiangmai & Chiangrai |archive-url  = https://web.archive.org/web/20110928105132/http://www.chiangmai-chiangrai.com/siamese_money.html |archive-date = September 28, 2011 |url-status= dead |df= mdy-all}}</ref><ref>{{cite web |script-title=th:เหรียญกษาปณ์ของไทย |trans-title=Coins of Thailand |url=http://www1.mod.go.th/heritage/nation/krasab/index1.htm |website=Ministry of Defense of Thailand |access-date=15 October 2011 |language=th |archive-url=https://web.archive.org/web/20120204133229/http://www1.mod.go.th/heritage/nation/krasab/index1.htm |archive-date=2012-02-04 |url-status=dead }}</ref>

Until 27 November 1902, the baht was fixed on a purely silver basis, with 15&nbsp;grams of silver to the baht. This caused the value of the currency to vary relative to currencies on a [[Chemistry:Gold standard|gold standard]]. From 1856 to 1864, the values of certain foreign silver coins were fixed by law, with 5 baht = 3 Spanish dollar = 7 Indian rupees.<ref>{{cite web |script-title=th:รัชกาลที่ 4 รับสั่งทำ "เหรียญกระษาปณ์" รับมือการค้ากับต่างชาติ |trans-title=King Mongkut ordered the production of western style coins as the response to the rising trades with foreigners|url=https://www.silpa-mag.com/history/article_29937|website=Silpa Watthanatham Magazine|date=27 March 2019|access-date=22 November 2020|language=th|archive-date=21 November 2020|archive-url=https://web.archive.org/web/20201121204620/https://www.silpa-mag.com/history/article_29937|url-status=live}}</ref> Before 1880 the exchange rate was fixed at 8 baht per [[Finance:Pound sterling|pound sterling]], falling to 10 to the pound during the 1880s.

In 1902, the government began to increase the value of the baht by following all increases in the value of silver against gold but not reducing it when the silver price fell. Beginning at 21.75 baht per [[Finance:Pound sterling|pound sterling]], the currency rose in value until, in 1908, a fixed peg to the British pound sterling was established of 13 baht per pound. This was revised to 12 baht in 1919 and then, after a period of instability, to 11 baht in 1923. During [[Social:World War II|World War II]], the baht was fixed at a value of one [[Finance:Japanese yen|Japanese yen]] on 22 April 1942.<ref>{{cite web |script-title=th:กฎกระทรวงการคลัง ออกตามความในพระราชบัญญัติ เงินตราในภาวะฉุกเฉิน พุทธศักราช 2484 (ฉะบับที่ 3) |trans-title=Ministry of Finance Regulation issued according to Currency during the Emergency Situation of BE 2484 (Issue No. 3)

[[Biology:Cowrie|Cowrie]] shells from the [[Earth:Mekong|Mekong]] River had been used as currency for small amounts since the Sukhothai period. Before 1860, Thailand did not produce coins using modern methods. Instead, a so-called "bullet" coinage was used, consisting of bars of metal, thicker in the middle, bent round to form a complete circle on which identifying marks were stamped.<ref>{{cite web |url=http://www.matichon.co.th/mtc-flv-window.php?newsid=1323259839 |script-title=th:อันซีน "พิพิธภัณฑ์มีชีวิต ธนบัตรมีเรื่องราว" แห่งเดียวในประเทศไทย [Unseen living museum - Banknotes have stories from the unique museum in Thailand]|language=th |work=Matichon |access-date=8 December 2011 |archive-url=https://web.archive.org/web/20151222112321/http://www.matichon.co.th/mtc-flv-window.php?newsid=1323259839 |archive-date=2015-12-22 |url-status=dead }}</ref><ref>{{cite book|title=เบี้ย บาท กษาปณ์แบงค์ [Cowrie, Baht, Coins, and Bank] โดย นวรัตน์ เลขะกุล|first=Nawarat |last=Lekhakum|publisher= สำนักพิมพ์สารคดี [Sarakhadee Press]|language=th |date=2009}}</ref> Denominations issued included {{frac|128}}, {{frac|64}}, {{frac|32}}, {{frac|16}}, {{frac|8}}, {{frac|2}}, 1, {{frac|1|1|2}}, 2, {{frac|2|1|2}}, 4, {{frac|4|1|2}}, 8, 10, 20, 40 and 80 baht in silver and {{frac|32}}, {{frac|16}}, {{frac|8}}, {{frac|2}}, 1, {{frac|1|1|2}}, 2 and 4 baht in gold.

Rama III (1824–1851) was the first king to consider the use of a flat coin. He did so not for the convenience of traders, but because he was disturbed that the creatures living in the cowrie shells were killed. When he learned of the use of flat copper coins in Singapore in 1835, he contacted a Scottish trader, who had two types of experimental coins struck in England. The king rejected both designs. The name of the country put on these first coins was ''Muang Thai'', not ''Siam''.<ref>{{cite web|url=http://phila09-04.eurseree.com/cgi-bin/info/agora.cgi?cart_id=5286534.107769*KJ66o8&p_id=1196&xm=on&ppinc=search2|title=1835 Rama III unadopted design copper coin "Lotus - MuangThai"|access-date=2015-10-20|archive-date=2015-12-22|archive-url=https://web.archive.org/web/20151222110629/http://phila09-04.eurseree.com/cgi-bin/info/agora.cgi?cart_id=5286534.107769*KJ66o8&p_id=1196&xm=on&ppinc=search2|url-status=live}}</ref><ref>{{cite web|url=http://www.royalthaimint.net/ewtadmin/ewt/mint_web/ewt_news.php?nid=46&filename=index|script-title=th:เงินตรา|website=Royal Thai Mint|language=th|access-date=20 October 2015|archive-url=https://web.archive.org/web/20160304103729/http://www.royalthaimint.net/ewtadmin/ewt/mint_web/ewt_news.php?nid=46&filename=index|archive-date=4 March 2016|url-status=dead}}</ref>

In 1860, modern style coins were introduced. These were silver 1 sik, 1 fuang, 1 and 2 salung, 1, 2 and 4 baht, with the baht weighing 15.244&nbsp;grams and the others weight-related. Tin 1 solot and 1 att followed in 1862, with gold {{frac|2|1|2}}, 4 and 8 baht introduced in 1863 and copper 2 and 4 att in 1865. Copper replaced tin in the 1 solot and 1 att in 1874, with copper 4 att introduced in 1876. The last gold coins were struck in 1895.

=== Decimal coinage ===
In 1897, the first coins denominated in satang were introduced, [[Chemistry:Cupronickel|cupronickel]] {{frac|2|1|2}}, 5, 10 and 20 satang. However, 1 solot, 1 and 2 att coins were struck until 1905 and 1 fuang coins were struck until 1910. In 1908, holed 1, 5 and 10 satang coins were introduced, with the 1 satang in bronze and the 5 and 10 satang in nickel. The 1 and 2 salung were replaced by 25 and 50 satang coins in 1915. In 1937, holed, bronze {{frac|2}} satang were issued.

In 1941, a series of silver coins was introduced in denominations of 5, 10 and 20 satang, due to a shortage of nickel caused by [[Social:World War II|World War II]]. The next year, tin coins were introduced for 1, 5 and 10 satang, followed by 20 satang in 1945 and 25 and 50 satang in 1946. In 1950, [[Chemistry:Aluminium bronze|aluminium bronze]] 5, 10, 25 and 50 satang were introduced whilst, in 1957, bronze 5 and 10 satang were issued, along with 1-baht coins struck in an unusual alloy of copper, nickel, silver and zinc. Several Thai coins were issued for many years without changing the date. These include the tin 1942 1 satang and the 1950 5 and 10 satang, struck until 1973, the tin 1946 25 satang struck until 1964, the tin 50 satang struck until 1957, and the aluminium bronze 1957 5, 10, 25 and 50 satang struck until the 1970s. Cupronickel 1-baht coins were introduced in 1962 and struck without date change until 1982.

In 1972, cupronickel 5-baht coins were introduced, switching to cupronickel-clad copper in 1977. Between 1986 and 1988, a new coinage was introduced, consisting of aluminium 1, 5 and 10 satang, aluminium-bronze 25 and 50 satang, cupronickel 1 baht, cupronickel-clad-copper 5 baht and bimetallic 10 baht. Cupronickel-clad-steel 2 baht were introduced in 2005.

In 2008, the Ministry of Finance and the Royal Thai Mint announced the 2009 coin series, which included changes in materials to reduce production costs as well as an update of the image on the obverse to a more recent portrait of the king. The two-baht coin, confusingly similar in color and size to the one-baht coin, was changed from nickel-clad low-carbon steel to aluminium bronze. New two-baht coin was the first of the new series released on February 3, 2009, followed by the satang coins in April, a five-baht coin in May, a ten-baht coin in June, and a one-baht coin in July 2009.

In 2018, the Royal Thai Mint and the Ministry of Finance issued a new series of general circulation coins, featuring the same standard specifications, but feature a portrait of its current king, Maha Vajiralongkorn.

In 1851, the government issued notes for {{frac|8}}, {{frac|4}}, {{frac|3|8}}, {{frac|2}} and 1 tical, followed by 3, 4, 6 and 10 tamlueng in 1853. After 1857, notes for 20 and 40 ticals were issued, also bearing their values in Straits dollars and Indian rupees. Undated notes were also issued before 1868 for 5, 7, 8, 12 and 15 tamlueng, and 1 chang. One att notes were issued in 1874.

In 1892, the treasury issued notes for 1, 5, 10, 40, 80, 100, 400 and 800 ticals, called "baht" in the Thai text.

On September 19, 1902, the government introduced notes which were printed by Thomas De La Rue & Company Limited, England, during the reigns of kings Rama V and Rama VI, denominated 5, 10, 20, 100 and 1000 ticals, still called baht in the Thai text — each denomination having many types,<ref>{{cite web

==== Series 1 ====
[[File:Series 1 Banknote Siam.jpg|thumb|325x325px]]
Series 1 was chosen due to the series which precedes this were non-decimal. Series 1 banknotes is the first series to be produced by Thomas De La Rue & Company Limited. In 1900, Charles James Rivett Carnac, a Royal Treasury Ministry advisor proposed that the Siamese Baht followed the issuances of banknotes followed the British standard. The banknote department was established quickly thereafter. The main characteristic of this series was that the notes are onesided and multilingual, containing Chinese, Malay (in Jawi script), and Latin script.<ref>{{Cite web |title=1st Series Thai Banknotes |url=http://www.siambanknote.com/banknote-appraisal/1st-series-thaibanknote-price.htm |access-date=2023-09-11 |website=www.siambanknote.com}}</ref> It was also the last series to use the term "tical" to refer to the Thai Baht, and the largest in term of size of circulated notes.

==Money and unit of mass==
''Ngoen'' (เงิน) is Thai for "[[Chemistry:Silver|silver]]" as well as the general term for [[Finance:Money|money]], reflecting the fact that the baht (or tical) is foremost a unit of [[Physics:Mass|weight]] for [[Chemistry:Precious metal|precious metal]]s and [[Earth:Gemstone|gemstone]]s. One baht = 15.244 [[Gram|gram]]s.<ref>[http://www.bangkokpost.com/news/local/30756/a-sure-bet-or-fool-gold "A sure bet or fool's gold?"], ''Bangkok Post'' 2010-01-10{{Dead link|date=October 2018}}</ref> Since the standard purity of Thai [[Chemistry:Gold|gold]] is 96.5 percent, the actual gold content of one baht by weight is 15.244 × 0.965 = 14.71046&nbsp;grams; equivalent to about 0.473 troy ounces. 15.244&nbsp;grams is used for [[Chemistry:Bullion#Bullion|bullion]]; in the case of jewellery, one baht should be more than 15.16&nbsp;grams.

==Exchange rates==
[[File:USD rate to THB.svg|thumbnail|Historical exchange rate of USD/THB from 1980 to 2015]]
[[File:Euro exchange rate to THB.svg|thumbnail|Historical exchange rate of EUR/THB since 2005]]
The Bank of Thailand adopted a series of exchange controls on 19 December 2006, which resulted in a significant divergence between offshore and onshore exchange rates, with spreads of up to 10 percent between the two markets. Controls were broadly lifted on 3 March 2008 and there is now no significant difference between offshore and onshore exchange rates.<ref>{{cite news | url=http://in.reuters.com/article/idINSP20869920080303 | work=Reuters | title=UPDATE 1-Onshore and offshore Thai baht converge, c.bank seen | date=3 March 2008 | access-date=12 September 2010 | archive-date=22 November 2020 | archive-url=https://web.archive.org/web/20201122120207/https://in.reuters.com/article/idINSP20869920080303 | url-status=live }}</ref>
