The Reserve Bank of India’s currency printing operation invites bids from manufacturers to supply polymer substrate sheets used for banknote production with incorporated security features. Bloomberg and Business Standard both report that this procurement step is aimed at sourcing the materials required for polymer banknotes, indicating progress toward a possible shift in India’s banknote manufacturing process. The bid request focuses on polymer note material suitable for printing, rather than on the banknotes themselves. Business Standard adds that the RBI has not publicly announced specific denominations or a timeline for when polymer banknotes would be introduced. Taken together, the reports describe the effort as India’s first formal procurement move related to polymer banknote technology, while leaving key implementation details—such as which note values would be converted and when—still unspecified by the central bank.
