The ministry has existed in form since the 15th century during the Ayutthaya Kingdom. Then, the ministry was called the "Kromma Khlang" (Thai: กรมคลัง) and eventually upgraded to “Krom Phla Khlang” (Thai: กรมพระคลัง, sometimes written as "Berguelang" or "Barcelon" by foreign authors). The "Phla Khlang" or minister had wide ranging powers include those of taxation, trade, monopolies, tributes, and even foreign affairs.
Most of these features were retained during the Rattanakosin era. In 1855 King Mongkut signed the Bowring Treaty with the United Kingdom. The treaty exposed Siam to modern trade and international commerce; the king was forced to set customs duty rate at no more than three percent; the country was at a disadvantage, but international trade grew. Soon the king was forced to set up a customs house (Thai: ศุลกสถาน) and the Royal Mint to deal with new challenges.
During the reign of King Chulalongkorn (Rama V), the ministry took its present shape. The king issued a royal decree in 1873 consolidating all powers and agencies under one ministry with a more focused portfolio. He appointed one of his uncles, Prince Maha Mala Pamrabporapat as its first minister. The ministry finally came into its own in 1933 via the Civil Service Reform Act of 1933. The Royal Treasury Ministry was then changed to the Ministry of Finance which now consists of 10 departments and 14 state enterprises.
