DHAKA, Dec 02, 2025 (BSS) – Bangladesh Bank (BB) is set to release a newly designed Taka 500 banknote from Thursday as part of its ongoing "Historical and Archaeological Architecture of Bangladesh" series.   The new note, signed by Governor Dr. Ahsan H. Mansur, will initially be issued from the central bank's Motijheel office before being distributed through other branches.   The new note measures 152mm x 65mm and features a predominantly green color scheme.   The left side displays the Central Shaheed Minar, while the center background features a blooming Water Lily (Shapla) with leaves.   The reverse side showcases the Supreme Court of Bangladesh.    A portrait of the Royal Bengal Tiger, a bright electrotype '500', and the Bangladesh Bank monogram are embedded as watermarks.   To ensure authenticity, the note incorporates 10 distinct security features.   The value '500' in the top right corner is printed with optically variable ink. When tilted, the colour shifts from green to blue, revealing a diagonal '500' inside.   A 4mm wide twisted thread combines red and bright gold. Upon tilting, the red portion turns green (showing Taka 500), while the gold portion displays moving rainbow-colored bars.    A latent image of the number '500' is hidden in the green design of the bottom border, visible only when held horizontally. Additionally, a see-through image of '500' beside the Governor’s signature becomes visible against light.   The note is designed to be accessible to the visually impaired, featuring five small, raised dots on the bottom right corner. Rough intaglio printing is used for key elements, including the Shaheed Minar, the bank's name, the diagonal lines on the right, and the Supreme Court image, allowing users to feel the texture.   The note utilizes UV curing varnish on both sides, giving it a glossy feel and increased durability. Under a UV detector, the Water Lily image fluoresces magenta, and red, blue, and green fibers scattered within the paper become visible.    Micro printing of 'BANGLADESH BANK' is also present in various locations, viewable only with a magnifying glass.   Bangladesh Bank has confirmed that all currently circulating notes and coins will remain legal tender alongside the new issue. For numismatists, non-exchangeable Specimen versions of the note will be available for purchase at the Taka Museum in Mirpur.   This release follows the earlier issuance of new 1000, 100, 50, and 20 Taka notes under the same architectural series.
