RBI Revives Polymer Banknote Plan After More Than a Decade

The Reserve Bank of India is once again considering the introduction of polymer banknotes, reviving a proposal that was first explored more than a decade ago, according to a report by Business Standard. The move comes at a time when the cost of printing currency notes is rising sharply and billions of soiled notes continue to be withdrawn from circulation every year.

The RBI is expected to announce a pilot project in the near future, with discussions reportedly taking place during the central bank’s last two board meetings held in Patna and Mumbai. Lower denomination notes such as the ₹10 and ₹20 are likely to be selected for the initial trial because they deteriorate quickly due to frequent circulation.

Polymer banknotes are made from a synthetic plastic substrate instead of the traditional cotton-based paper used in Indian currency. These notes are generally more durable, resistant to moisture and dirt, and can last significantly longer in circulation. Polymer notes also allow the incorporation of advanced security features, including transparent windows and complex anti-counterfeiting elements. Several countries, including Australia, Canada, the United Kingdom, and Singapore, have already adopted polymer currency successfully.

The RBI’s renewed interest is largely driven by rising printing costs and the increasing disposal of damaged notes. According to Business Standard, expenditure on printing currency notes increased to ₹6,372.8 crore in FY25 from ₹5,101.4 crore in the previous financial year. During the same period, around 23.8 billion pieces of soiled banknotes were withdrawn from circulation, compared to 21.24 billion pieces in FY24. The ₹500 denomination accounted for the largest share among the withdrawn notes, followed by ₹100 notes.

Despite the rapid growth of digital payments, India continues to witness strong demand for physical cash. Currency in circulation reportedly reached a record ₹42.86 trillion as of 15 May, registering an 11.5 per cent year-on-year increase. In the first one and a half months of FY27 alone, circulation expanded by ₹1.15 trillion.

India had earlier experimented with polymer notes in 2012 when the government approved a field trial of one billion ₹10 polymer banknotes in Kochi, Mysore, Jaipur, Bhubaneswar, and Shimla. The objective was mainly to study durability under different climatic conditions. However, the proposal was later shelved because of technological and operational challenges, particularly issues related to ATM compatibility and cash-handling systems. According to sources quoted by Business Standard, those technological limitations have now largely been resolved.

For numismatists and notaphilists, the possible introduction of polymer currency represents an important development in the history of Indian paper money. If introduced, polymer notes would become a significant transitional issue in modern Indian notaphily, much like the earlier shifts in banknote design, security features, and substrate technology. Trial issues and first releases could eventually become highly collectible pieces documenting a new phase in India’s monetary evolution.

At present, the RBI is expected to proceed cautiously through a pilot project rather than a complete replacement of paper currency. The broader rollout of polymer notes would depend on operational feasibility, public acceptance, and the overall success of the trial. According to sources familiar with the discussions, the proposal is aimed at reducing long-term production costs while extending the lifespan of notes in circulation.
