Mumbai: The Reserve Bank of India (RBI) is once again considering the introduction of polymer currency notes as part of efforts to reduce long-term printing costs and improve the durability of banknotes in circulation. The proposal has reportedly been discussed during recent RBI board meetings held in Patna and Mumbai, signalling renewed interest in a move that was previously tested but never implemented on a large scale.
The renewed focus on polymer notes comes amid persistent challenges related to currency printing expenses and the rapid deterioration of paper notes due to heavy circulation and diverse climatic conditions across the country.
Why RBI is considering polymer notes
Polymer banknotes are made from a specialised plastic substrate rather than traditional paper. They are widely regarded as more durable, cleaner and resistant to moisture, dirt and wear and tear.
These characteristics make polymer notes particularly suitable for countries with humid climates and high cash usage. Although polymer notes cost more to produce initially, their longer lifespan reduces the need for frequent replacement, potentially resulting in substantial savings over time.
The RBI’s latest review is reportedly being driven by data indicating that the cost of maintaining India’s vast currency circulation system remains significant despite fluctuations in annual printing expenditure.
Currency printing remains expensive
According to RBI annual report data, expenditure on printing currency notes rose to Rs 6,372 crore in FY25 before declining to Rs 4,875 crore in FY26.
While the reduction offers some relief, printing costs remain a substantial burden. An exceptional spike was recorded in FY17 when expenditure reached Rs 7,965 crore following demonetisation and the introduction of new currency notes.
Experts point out that printing costs are only one aspect of the challenge. A significant portion of resources is spent replacing damaged, soiled and worn-out notes that are withdrawn from circulation each year.
The recurring replacement cycle has prompted policymakers to explore alternatives that could extend the usable life of currency notes and improve operational efficiency.
High circulation drives note replacement
Data on note disposal indicates that high-value and frequently used denominations account for the largest share of currency withdrawn from circulation.
In FY26, approximately 598.3 crore pieces of Rs 500 notes and 581.1 crore pieces of Rs 100 notes were removed from circulation due to wear and damage. These figures underline the scale of currency replacement required annually and the associated costs involved.
Since polymer notes generally remain in circulation much longer than paper notes, they could help reduce the volume of replacement printing required each year.
Global adoption of polymer currency
Several countries have already adopted polymer banknotes either fully or partially. Australia pioneered the technology and has completely transitioned to polymer currency. Other major economies, including Canada and the United Kingdom, have also embraced polymer notes because of their durability and enhanced security features.
Polymer banknotes often incorporate advanced anti-counterfeiting measures, making them more difficult to forge than traditional paper currency.
Despite the growing global trend, many countries, including India, continue to rely primarily on paper-based banknotes.
India’s earlier experiment
India first experimented with polymer currency in 2012 through a pilot project. However, the initiative did not progress beyond the testing stage, and paper currency continued to dominate circulation.
The reasons for the limited rollout included logistical challenges, production considerations and the need for further evaluation of costs and operational feasibility.
With the RBI now reviewing the proposal again, the discussion has regained momentum. The combination of rising maintenance costs, frequent note replacement and successful international examples has strengthened the case for polymer currency.
Focus on long-term efficiency
If implemented, polymer notes could represent a significant shift in India’s currency management strategy. Beyond reducing replacement costs, they may improve note quality, durability and security while helping the RBI manage the country’s large cash-based economy more efficiently.
Although no final decision has been announced, the renewed discussions indicate that policymakers are exploring long-term solutions to make currency circulation more sustainable and cost-effective.
