The Bank of Thailand will issue two commemorative 100-baht banknote designs honoring Queen Sirikit the Queen Mother and Princess Bajrakitiyabha. Each design will have 10 million notes, available at face value from 21 December 2026 through designated Thai financial institutions.
The notes’ fronts match the current 17th Series 100-baht polymer banknote. Their reverses depict royal duties and initiatives, with fluorescent features visible under ultraviolet light.
Mr. Vitai Ratanakorn, Governor of the Bank of Thailand (BOT), announced that the Bank of Thailand has graciously been granted Royal Permission to issue commemorative banknotes in remembrance of Her Majesty Queen Sirikit The Queen Mother and Her Royal Highness Princess Bajrakitiyabha Narendiradebyavati Kromluangrajasarinisiribajra Mahavajrarajdhita. The commemorative banknotes are intended to express profound sorrow and honor their enduring benevolence and contributions to the Thai people and the nation, while providing the public with an opportunity to obtain the banknotes as keepsakes.
The BOT has produced two designs of commemorative banknotes in a denomination of 100 baht, with 10 million notes issued for each design. These commemorative banknotes will be available for exchange at their face value from 21 December 2026 onwards, at any commercial banks, the Government Savings Bank, the Bank for Agriculture and Agricultural Cooperatives, the Government Housing Bank, and the Islamic Bank of Thailand.
Regarding the designs, the front side of the commemorative banknotes is identical to the current 17th Series 100-baht polymer banknote currently in circulation. The reverse side features images depicting royal duties and initiatives undertaken for the well-being of the Thai people and the nation, reflecting memorable moments that remain cherished by the Thai public. The two commemorative banknotes also feature special fluorescent elements that glow under ultraviolet light in colors and patterns distinct from those of circulating banknotes.
