The baht (; th|บาท, pronounced as /th/; sign: ฿; code: THB) is the official currency of Thailand. It is divided into 100 satang (Thai: สตางค์, pronounced as /th/). Prior to decimalisation, the baht was divided into eight fueang (Thai: เฟื้อง, pronounced as /th/), each of eight at (Thai: อัฐ, pronounced as /th/). The issuance of currency is the responsibility of the Bank of Thailand. SWIFT ranked the Thai baht as the 10th-most-frequently used world payment currency as of December 2023.[1]

The Thai baht, like the pound, originated from a traditional unit of mass. Its currency value was originally expressed as that of silver of corresponding weight (now defined as 15 grams), and was in use probably as early as the Sukhothai period in the form of bullet coins known in Thai as photduang.[2] These were pieces of solid silver cast to various weights corresponding to a traditional system of units related by simple fractions and multiples, one of which is the baht. These are listed in the following table:[3] [4] Though the coins themselves have names like: solot, siao, sik, etc, the formal division of the Thai baht (tical) is 1 baht = 8 fueang = 64 at. This means that one baht is divided into eight fueang, and each one fueang is divided into 8 at. Currently, the Thai baht do not employ the at as a subunit, but the at is the current subunit of the Lao kip.

Until 27 November 1902, the baht was fixed on a purely silver basis, with 15 grams of silver to the baht. This caused the value of the currency to vary relative to currencies on a 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.[6] Before 1880 the exchange rate was fixed at 8 baht per 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 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 World War II, the baht was fixed at a value of one Japanese yen on 22 April 1942.[7] [8]
From 1956 until 1973, the baht was pegged to the US dollar at an exchange rate of 20.8 baht = one dollar and at 20 baht = 1 dollar until 1978.[9] [10] A strengthening US economy caused Thailand to re-peg its currency at 25 to the dollar from 1984 until 2 July 1997, when the country was affected by the 1997 Asian financial crisis. The baht was floated and halved in value, reaching its lowest rate of 56 to the dollar in January 1998. It rose to 30 per dollar in January 2021.
The baht was originally known to foreigners by the term tical,[11] which was used in English language text on banknotes until the series 2 1925.[12] [13]
The currency symbol for the baht is (a latin letter B with a vertical stroke). In 1986, this symbol was given a codepoint for computer use in the Thai Industrial Standard 620-2533 (Thailand's extension of ASCII), at position 0xDF. This national standard was subsequently subsumed into international standards as ISO/IEC 8859-11 ("ISO Latin-Thai"). In turn, the ISO 8859 series were transposed into the Unicode standard,[14] where the symbol was allocated the codepoint .[15] The symbol is also used for the Panamanian balboa.[16]
In Thai usage, the baht (Thai: บาท) is legally abbreviated as Thai: บ. according to Section 7 of the Currency Act, B.E. 2501.[17]
For a time, the baht symbol was appropriated by some as a symbol for Bitcoin, a cryptocurrency. Following representations,[18] a separate code point (a latin letter B with two vertical strokes) was allocated in Unicode version 10.0.[19]
In Unicode 1.0, two codepoints were allocated to the baht, one as the currency symbol in the Thai range and one in the CJK Compatibility block as a square version of the Japanese word for "baht", written in katakana script. The CJK codepoint,, is documented in subsequent versions of the standard as "a mistaken, unused representation" and users are directed to instead.[20] Consequently, only a few computer fonts have any content for this codepoint and its use is deprecated.[21]
(The Japanese for "baht" is Japanese: {{big|'''バ''' . However, the reference glyph (㌬) and the character name correspond to Japanese: {{big|'''パ''' (from English "parts").)
Before decimalization, the Siamese government employed Chinese, Latin, Jawi (Malay), Devanagari, Khmer and Khom, Lanna, and Burmese scripts in banknotes and coins, as seen. The reason is not clear, though it is a common understanding that it is to ease the facilicitation of trade within Siam. It could also be the case that at the time, the capital, Bangkok (Phra Nakhon) was still a multi-cultural city, so as to be more inclusive, the government added various other language onto the currency - though by the second series after the decimalization in the 1900s, the currency was all but monolingual.
Chinese: c=圓|p=yuán|labels=no (Thai: บาท): This character was use during the times of Rama IV to represent baht, though this was phased out by another character which is in partially and informally used today. The only occurrence of this character was in Rama IV's banknote series.
Chinese: t=銖|s=铢|p=zhū|labels=no|first=t (Thai: บาท): This character was in use from 1868–1925 officially on banknotes to represent baht. It is still in use today unofficially to refer to the Thai baht in general, as in Chinese: 泰銖 or Chinese: 泰铢.
Chinese: t=錢|s=銭|p=qián|labels=no|first=t (Thai: สลึง): This character was in use from 1851–1908 officially on banknotes and coins to represent salueng.
Chinese: c=方|p=fāng|labels=no (Thai: เฟื้อง): This character was in use from 1851–1908 officially on banknotes and coins to represent fueang.
The notation for these chinese character are written like they are in Thai, though there is a caveat: it is written right to left, as was the convention back then, so one baht is written Chinese: 圓壹 or Chinese: 銖壹, if there are smaller units involved the notation can write like such: Chinese: 方銭參圓壹 for one baht, three salueng, and one fueang.
Cowrie shells from the 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.[22] [23] Denominations issued included,,,,,, 1,, 2,, 4,, 8, 10, 20, 40 and 80 baht in silver and,,,, 1,, 2 and 4 baht in gold. One gold baht was generally worth 16 silver baht. Between 1858 and 1860, foreign trade coins were also stamped by the government for use in Thailand.
Photduang, a form of currency used during the Sukhothai period, was characterized by its longer legs, which created a larger and wider hole in the middle. These coins were primarily made of silver and featured a cut across the front of each leg. This cut served a dual purpose: it authenticated the money and allowed for the quality of the silver to be tested. Over time, as the Sukhothai Kingdom declined and became a vassal state of Ayutthaya—which was established as the capital in 1350—the design of photduang evolved. The coins became rounder with shorter legs, and the central hole, while still present, grew smaller. By the end of this era, the hole disappeared completely. The cuts on the legs also reduced in size and were eventually replaced by a small elliptical nick, known as "Met Kao San," on one side of the coin.[24]
The Thonburi period (1767–1782) and the Rattanakosin period, beginning in 1782, adopted the photduang design from the late Ayutthaya period. The coins from these periods had no central hole, and the legs were even shorter. A key difference was that Thonburi photduang lacked the elliptical nick, whereas the Rattanakosin coins reintroduced this feature, similar to the Ayutthaya coins. Photduang from these later periods typically featured two stamped marks: the dynasty mark on top and the king's personal mark on the front part. The dynasty mark often symbolized the kingdom's ruling dynasty, while the king's personal mark represented the reigning monarch.
The markings on photduang coins varied across different periods. During the Sukhothai era, some coins bore no marks, while others had up to 11. This variation was because, at that time, individuals and merchants could produce their own money. However, from the Ayutthaya period onward, the production of photduang was monopolized by the government, making it easier to identify coins from each era. Ayutthaya photduang typically bore two marks: the dynasty mark, which could be a spoked wheel symbolizing the "Wheel of Law" from Buddhist teachings or the Chakra (Vishnu's weapon), represented by a pattern of 8 dots surrounding a central dot. The king's personal mark varied with each ruler and included symbols such as a conch shell, a Garuda bird (khrut), an elephant, and an anchor, each symbolizing different aspects of the king's reign or divine associations.

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.[27] [28]
In 1860, modern-style coins were introduced. These were silver 1 sik; 1 fueang; 1 and 2 salueng; 1, 2, and 4 baht; with the baht weighing 15.244 grams and the others weight-related. Tin 1 solot and 1 at followed in 1862, with gold, 4, and 8 baht introduced in 1863 and copper 2 and 4 at in 1865. Copper replaced tin in the 1 solot and 1 at in 1874, with copper 4 at introduced in 1876. The last gold coins were struck in 1895.

The first issue of coins were commissioned by Rama IV, though it was never brought into circulation. This was one of the first attempt to replace the bullet coins, but few were ever minted without making it into circulation.[29]

The first circulating issue of the Siamese coins. This marked the start of the move away from using photduang currency. Though in this era, the photduang were still legal tender. In this series, the lower denominations were made of silver, and the higher ones were made of gold. These higher denominations were given nicknames: pot dueng, pit, and tot. Pot dueng means thirty two, as in 1/32 of a chang. The other nickname was the chinkang or one Chinese tamlueng.[30] The pit means twenty, as in 1/20 of a chang, the other name is ekkang, or one thai tamlueng.[31] The tot means ten, as in 1/10 of a chang. The coin was also called thukkang, which means two tamlueng.[32] In the lower denominations materials such as tin, copper and brass are used, since these are quite low value.

The first series to depict king Rama V, the coins of this issue were made of copper, silver, and gold. Though gold was strangely only used for the 1 fueang denomination.[33] The new shield emblem was introduced in this issue. This shield was separated into three section. Drawing from western influences, symbols within these sections represented territories Siam was controlling. The tree-headed elephant represented Siamese territory, the bottom-left elephant represented Lan Xang, and the warangka represented Siamese Malaya.

The decimalization of the Thai baht came about at the end of the 19th century. The minister of treasury, Jayanta Mongkol, the Prince Mahisara Rajaharudaya, suggested to King Rama V, that decimalization would make counting easier and further modernize Siam. Initially, there would be one superunit, chang, and one subunit, at. with the baht being in the middle. In summary, 64 at = 1 baht = 1/80 chang. In reality, this was just a simplification of the old system, which was scrapped.[34] In which, during the period of 1902–1908, Siam went back to the old system. Though in comparison, at is used as the subunit in Laos, compared to the satang in the Thai baht. The second attempt came at the end of Rama V's reign, where it was more widely accepted and put into effective use.
In 1897, the first coins denominated in satang were introduced, cupronickel, 5, 10, and 20 satang. However, 1 solot, 1, and 2 at coins were struck until 1905 and 1 fueang 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 salueng were replaced by 25 and 50 satang coins in 1915. In 1937, holed, bronze 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 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, 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.

The current coin series is the 14th issue.
In 2008, in the 13th issue, 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 3 February 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, Vajiralongkorn.

In February 2010 the Treasury Department of Thailand stated that it has been planning a new circulation 20-baht coin.[37]
See main article: Banknotes of the Thai baht. In 1851, the government issued notes for,,, 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 at 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 10 September 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,[38] with 1 and 50 tical notes following in 1918. In 1925, notes were issued in denominations of 1, 5, 10, 20, 100 and 1,000 baht with the denomination in both Arabic and Thai numerals without English text;[39] English speakers continued to refer to these as "ticals".[40]
On 27 July 2010, the Bank of Thailand announced that the 16th-series banknotes would enter circulation in December 2010.[41] [42] On 9 August 2012, the Bank of Thailand issued a new denomination banknote, 80 baht, to commemorate queen Sirikit's 80th birthday.[43] It was the first Thai banknote that featured Crane's MOTION security thread.
In 2017, the Bank of Thailand announced a new family of banknotes in remembrance of the late King Bhumibol Adulyadej (Rama IX). The notes are the same size and dimensions as the "Series 16" banknotes, with the front designs as before, but the back designs featuring images of the king's life in infancy, adolescence and maturity. The new family of banknotes were issued on September 20.[44]
In 2018, the Bank of Thailand announced a new family of banknotes featuring a portrait of the current King Vajiralongkorn (Rama X). The main colors and dimensions of the notes are the same as before, with the back designs featuring images of the Kings of Thailand from past to present.

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.

Ngoen (เงิน) is Thai for "silver" as well as the general term for money, reflecting the fact that the baht (or tical) is foremost a unit of weight for precious metals and gemstones. One baht = 15.244 grams.[68] Since the standard purity of Thai gold is 96.5 percent, the actual gold content of one baht by weight is 15.244 × 0.965 = 14.71046 grams; equivalent to about 0.473 troy ounces. 15.244 grams is used for bullion; in the case of jewellery, one baht should be more than 15.16 grams.
