Introduction of New Polymer Banknotes in Thailand

13 November 2025

In November 2025, the Bank of Thailand plans to introduce new polymer banknotes in denominations of 50 and 100 Baht. This step is part of a strategy to modernize the national currency, aimed at enhancing security, durability, and convenience of use. The new banknotes, designated as B201a and B202a, are made of polymer, making them resistant to wear, moisture, and contamination. The introduction is scheduled for November 21, 2025, which will allow for the gradual replacement of paper counterparts. This initiative aligns with global trends in banking, where polymer materials are increasingly used to combat counterfeiting.
Description of the 100 Baht Banknote (B202a)
The 100 Baht banknote has the catalog number B202 (PNL) and is equivalent to approximately 3.05 US dollars. The color scheme includes red, orange, brown, and green hues. The obverse features King Maha Vajiralongkorn Bodindradebayavarangkun (Rama X) in the Royal Thai Air Force uniform, as well as the Royal Garuda emblem. Thai text complements the design, emphasizing national identity.
The reverse also features Thai text, the Garuda emblem, and portraits of previous monarchs – Rama V and Rama VI, symbolizing the historical succession of the Chakri royal dynasty. Security features include a simulated security thread with demetallized inscription "100 บาท/100 BAHT" and a watermark in the form of a shadow image of Rama X. The banknote is printed at Note Printing Works, and its dimensions are 150 x 72 mm. The use of polymer ensures high resistance to mechanical damage, which is a key advantage compared to traditional paper banknotes.
Description of the 50 Baht Banknote (B201a)
The 50 Baht denomination, designated as B201 (PNL), is equivalent to approximately 1.50 US dollars. The primary color is blue, making it easily recognizable in everyday circulation. The obverse is similar to the 100 Baht banknote: an image of King Rama X in the Air Force uniform, the Royal Garuda emblem, and Thai text.
The reverse features Thai text, the Garuda emblem, and portraits of Rama III and Rama IV, reflecting key periods in Thailand's history, particularly the country's modernization in the 19th century. Security features are similar: a simulated security thread with demetallized inscription "50 บาท/50 BAHT" and a watermark with a shadow image of Rama X. The printing is done at the same facility – Note Printing Works. The banknote dimensions are 144 x 72 mm, and the material is polymer, guaranteeing durability and protection against counterfeiting.
Conclusion
The introduction of new polymer banknotes in 50 and 100 Baht denominations on November 21, 2025, marks an important stage in the modernization of Thailand's monetary system. These changes combine traditional elements of Thai culture with modern security technologies, ensuring reliability and convenience. The Bank of Thailand encourages citizens to familiarize themselves with the new banknotes for quick adaptation. Future expansion of the series to other denominations is expected, confirming the commitment to financial innovation.
