The Reserve Bank of India (RBI) is planning field trials for polymer-based Rs 10 and Rs 20 notes to improve currency durability and security. The initiative, targeting a rollout by the next financial year, aims to address the high replacement costs of paper currency. BRBNMPL has already begun seeking global tenders for the required materials, marking a significant step in re-evaluating plastic currency adoption.
The Reserve Bank of India (RBI) is preparing to re-introduce polymer banknotes, starting with field trials for the Rs 10 and Rs 20 denominations. The government has approved a plan to issue one billion pieces of each denomination as part of a pilot project, with a wider circulation target set for the beginning of the 2027-28 financial year.
The core objective behind this shift is to increase the lifespan of currency notes. Polymer notes, made from a plastic film called biaxially oriented polypropylene (BOPP), are estimated to last 2.5 to four times longer than traditional paper notes. They are designed to be more resistant to moisture, water, and daily wear and tear. Additionally, polymer notes allow for advanced anti-counterfeiting features, such as transparent windows, which are harder to replicate.
To facilitate this move, the Bharatiya Reserve Bank Note Mudran Private Limited (BRBNMPL) has initiated global tenders to procure the specialized polymer substrate sheets. Interested suppliers have until August 18, 2026, to submit their bids. This tender process is a critical first step in determining the feasibility of the project.
While the durability benefits are clear, the transition involves significant economic and operational trade-offs. Manufacturing polymer notes is estimated to be 30% to 60% more expensive than printing traditional paper currency. For the central bank, the primary challenge will be balancing these higher initial production costs against the long-term savings gained from less frequent note replacement. Investors and economists often monitor this cost-benefit analysis, as it directly impacts the central bank's operating expenses.
This is not the first time India has explored this technology. Over the past 15 years, there have been earlier attempts to introduce polymer currency, but these projects were shelved due to technical hurdles. Past challenges included issues with ink wear, problems with ATM compatibility, and concerns regarding how the material holds up in India's diverse and often extreme climatic conditions, such as high humidity and heat.
Given this history, the current field trials are essential. The success of the rollout will depend on how effectively these new notes perform in real-world conditions during the trial phase. For now, existing paper currency will remain in circulation, as the RBI does not plan to replace the current stock immediately. The next important update for this project will be the outcome of the tender process and the results of the initial field tests, which will provide clarity on whether the project can be scaled up successfully.
