The Bank of Thailand (BOT) will introduce new polymer 50- and 100-baht banknotes on November 21. These notes use specialized plastic material that resists moisture and dirt. This makes them much more durable than paper notes, offering a cleaner and longer-lasting option.
The 20-baht polymer note, released earlier, has lasted up to eight years—about four times longer than paper notes. The polymer 50- and 100-baht notes are expected to reduce the need for replacing banknotes by about 350 million pieces each year, saving costs, conserving resources, and benefiting the environment.
The new notes keep the same design as the current paper versions but add improved anti-counterfeiting features. The transparent window is visible from both sides, and the notes include embossed numerals and colour-shifting inks. These advanced security features help prevent counterfeiting.
To support those with visual impairments, the notes feature Braille-style markings indicating the denomination. They also have raised clear strips along the edges for easier identification.
Starting November 21, people can withdraw the new polymer notes at commercial banks and specialized financial institutions. The 100-baht polymer note will be available at ATMs and cash deposit/withdrawal machines (ATM/CDMs). Both denominations are compatible with vending machines.
The existing paper 50- and 100-baht notes will continue to circulate and remain valid for all transactions.
