The Indian government has approved the Reserve Bank of India’s (RBI) proposal to introduce polymer banknotes in ₹10 and ₹20 denominations for field trials, marking a major step towards testing plastic-based currency in the country.
Under the proposal, the RBI will introduce 1 billion ₹10 polymer banknotes and 1 billion ₹20 polymer banknotes, taking the total planned field trial to 2 billion notes. The move is aimed at evaluating the durability, security and performance of polymer currency under real-world conditions before any decision is taken on wider circulation.
The government approval was disclosed in Parliament by Minister of State for Finance Pankaj Chaudhary, following an RBI proposal for the field trials.
What are polymer banknotes?
Polymer banknotes are made from a thin, flexible plastic substrate rather than the traditional cotton-based paper used for Indian currency.
They are designed to withstand more physical wear and exposure to moisture than conventional paper notes.

Polymer notes have already been adopted by a number of countries around the world, particularly for denominations that experience heavy circulation.
Why India is testing polymer currency
The main objective of the Indian trial is to determine whether polymer notes can provide a longer usable life, particularly in lower denominations.
₹10 and ₹20 notes are frequently exchanged in everyday transactions, meaning they can experience considerable physical handling.
The government and RBI will therefore be able to assess how polymer notes perform under actual circulation conditions before deciding whether they should be introduced more widely.
Earlier government discussions on polymer currency have also identified extending the life of banknotes, particularly lower denominations, as a primary objective.
Why ₹10 and ₹20 notes were chosen
Lower-denomination notes generally circulate more frequently than higher-value banknotes.
A ₹10 or ₹20 note can pass through numerous hands during everyday transactions, making durability particularly important.

Replacement requirement
If polymer notes prove significantly more durable, the RBI could potentially reduce the frequency with which worn-out lower-denomination notes need to be replaced.
2 billion polymer notes will be tested
The field trial involves a substantial number of banknotes.
| Denomination | Polymer notes planned |
|---|---|
| ₹10 | 1 billion |
| ₹20 | 1 billion |
| Total | 2 billion |
The combined face value of the trial notes would be ₹30 billion, or ₹3,000 crore.

↓

↓

The face value represents the amount represented by the notes, not the cost of producing them.
This is a field trial, not a nationwide replacement
The government approval does not mean existing paper ₹10 and ₹20 notes will immediately disappear.
The purpose of the exercise is to test polymer currency in circulation and assess its performance.
A decision on regular issuance would depend on the outcome of the field trial. This approach is consistent with India’s earlier attempts to evaluate polymer banknotes before making a broader policy decision.

What will the RBI evaluate?
The field trial can help authorities assess several aspects of polymer currency.
These include:
- Durability
- Resistance to moisture
- Physical wear and tear
- Security features
- Public handling
- Machine compatibility
- Sorting and processing
- Printing quality
- Circulation behaviour
- Overall operational costs

Final policy decision
The real-world trial is important because laboratory testing alone cannot fully replicate the conditions banknotes face during everyday circulation.
Polymer notes can be more durable
One of the biggest potential advantages of polymer currency is durability.
Traditional paper banknotes can become dirty, torn or damaged after extensive circulation.
Polymer substrates are generally more resistant to water and physical wear.

↓

Potentially longer circulation
A longer lifespan could potentially reduce the frequency of replacement.
Water resistance is another advantage
Polymer banknotes are generally more resistant to water than conventional paper notes.
This could be particularly useful in a country with diverse climatic conditions, including areas with heavy rainfall and high humidity.
A banknote that remains usable after exposure to moisture could potentially remain in circulation for longer.
Security features could improve
Polymer banknotes can incorporate security features that are difficult to reproduce using conventional printing techniques.
These may include transparent or semi-transparent elements, specialised windows and other features designed to make authentication easier and counterfeiting more difficult.

Greater counterfeiting resistance
However, polymer does not make a banknote impossible to counterfeit.
Counterfeiters can also adapt to new technologies, meaning security systems need to evolve continuously.
Polymer notes are already used internationally
Polymer banknotes are not a new technology.
Several countries have introduced them for selected or all denominations.
Australia was an early major adopter of polymer currency, and the technology has since been used in various countries.
The experience of other central banks can provide useful information for India’s own trial.
India has considered polymer currency before
The current initiative is not India’s first attempt to explore polymer banknotes.
The government had previously decided to introduce 1 billion polymer ₹10 notes on a field-trial basis in five cities.
An earlier plan identified Kochi, Mysore, Jaipur, Bhubaneswar and Shimla as trial locations because of their varied geographical and climatic conditions.
The earlier initiative was intended to determine whether polymer notes could extend the life of lower-denomination currency.

The latest proposal therefore represents a renewed and expanded effort.
Why the earlier trials mattered
India’s varied geography makes currency durability a particularly important consideration.
A banknote can experience very different conditions depending on where it circulates.
For example:
Coastal region
High humidity
vs.
Dry region
Dust + heat
vs.
Mountain region
Cold + moisture
Testing polymer notes across different conditions can help the RBI determine whether they offer consistent advantages over paper currency.
Potential reduction in replacement costs
If polymer notes last significantly longer, the RBI could potentially reduce the frequency with which worn-out notes are removed from circulation and replaced.
This could create savings in:
- Printing
- Transportation
- Storage
- Sorting
- Destruction of damaged notes
- Distribution of replacement currency
However, polymer banknotes can also have higher production costs, meaning the overall economics will depend on their useful life.
Higher initial production cost
↓
Longer circulation life
↓
Fewer replacements
↓
Lower replacement frequency
↓
Potential lifecycle savings
The field trial will help determine whether those potential savings justify the transition.
The environmental question
Polymer currency also raises environmental considerations.
Unlike cotton-based banknote paper, polymer notes are made using plastic-based material.
This means authorities need to consider what happens to worn-out polymer notes at the end of their circulation life.
Potential recycling and disposal processes will therefore be important parts of assessing the technology.
The RBI had previously examined environmental impacts and carbon footprints associated with polymer versus paper currency during earlier evaluations.
Polymer does not necessarily mean India’s paper currency will disappear
The introduction of polymer notes would not automatically mean that all Indian banknotes will become plastic.
The RBI could choose to use polymer only for selected denominations if the technology proves advantageous.

The final decision would depend on factors such as cost, durability, security and operational compatibility.
What happens to existing ₹10 and ₹20 notes?
Existing paper ₹10 and ₹20 notes are not automatically being withdrawn because of the trial.
The polymer notes would initially be introduced for testing alongside the existing currency system.
The RBI would assess their performance before considering any broader policy change.
This means people can continue using existing valid ₹10 and ₹20 notes normally unless the RBI separately announces otherwise.
How polymer notes could affect cash handling
Banks and cash-handling companies use machines to count, sort and authenticate banknotes.
Introducing a new substrate therefore requires extensive testing.

The field trial will help identify whether existing infrastructure needs adjustments.
ATMs and cash machines may need testing
Although polymer notes are designed to behave similarly to conventional currency in many respects, their physical properties differ.
Banks and cash-processing companies will need to ensure that machines can reliably:
- Recognise polymer notes
- Count them
- Sort denominations
- Detect counterfeits
- Reject damaged notes
- Process notes at high speed
This is one reason a controlled field trial is important before a wider rollout.
What will happen if the trial succeeds?
If the trial demonstrates that polymer notes are durable, secure and economically viable, the RBI could consider expanding their issuance.
Possible future options could include:
- Regular issuance of ₹10 polymer notes
- Regular issuance of ₹20 polymer notes
- Expansion to other denominations
- Wider geographic circulation
- Gradual transition from paper to polymer for selected denominations
However, none of these outcomes is guaranteed at this stage.

Could other denominations eventually become polymer?
It is possible, but there is currently no basis to assume that all denominations will be converted.
The RBI would need to evaluate each denomination separately based on circulation patterns, production costs, security requirements and operational considerations.
Lower denominations may provide the strongest case because they tend to experience heavy handling.
What does this mean for consumers?
For ordinary consumers, the biggest potential change would be the physical feel and durability of the notes.
Polymer notes are generally smoother and more durable than traditional paper notes.
They can also behave differently when folded or handled.

Consumers would likely need some time to become familiar with the new notes if they eventually enter wider circulation.
The trial could modernise India’s cash system
India has rapidly expanded digital payments through UPI and other electronic payment systems.
However, cash remains an important part of the economy, particularly for smaller transactions.
The polymer-note initiative represents a modernisation of the physical cash system rather than a replacement for digital payments.

Both systems can continue to coexist.
Digital payments do not eliminate the need for durable cash
Even with rapid UPI adoption, physical currency continues to play an important role.
Cash is particularly relevant for:
- Small-value transactions
- Informal businesses
- Rural markets
- Areas with limited connectivity
- Situations where digital payment infrastructure is unavailable
Making frequently circulated notes more durable could therefore remain economically useful.
Why the announcement matters
The government’s approval represents a significant development in India’s currency-management strategy.
For the first time in this new trial, both ₹10 and ₹20 denominations are included, with a combined 2 billion notes planned for testing.
The move could eventually provide the RBI with evidence to determine whether polymer currency should become a permanent part of India’s banknote system.

Conclusion
The Indian government’s approval of field trials for polymer ₹10 and ₹20 banknotes marks a significant development in the country’s currency system.
The proposal involves 1 billion ₹10 notes and 1 billion ₹20 notes, or 2 billion polymer banknotes in total, with a combined face value of ₹3,000 crore.
The primary objective is not simply to make India’s currency look different.
The trial is intended to answer a practical question: Can polymer banknotes provide a longer-lasting, secure and economically viable alternative to conventional paper currency?
Lower denominations such as ₹10 and ₹20 are particularly suitable for testing because they are frequently used in everyday transactions and therefore experience substantial physical wear.
If polymer notes last considerably longer, the RBI could potentially reduce the frequency of replacement and associated currency-management requirements.
The technology could also offer advantages in terms of water resistance and the incorporation of security features.
However, polymer currency also comes with challenges.
The initial production cost can be higher than that of conventional banknotes, while the environmental impact, recycling of worn-out notes and compatibility with India’s cash-handling infrastructure will need to be considered.
The field trial is therefore crucial.
It will allow the RBI to gather real-world evidence across different conditions before deciding whether polymer currency should be introduced more widely.
Importantly, the approval does not mean India is abandoning paper currency.
Existing ₹10 and ₹20 notes will not suddenly become invalid simply because polymer versions are being tested. The polymer notes will initially be part of a trial, and any permanent transition would require a separate decision based on the results.
The initiative also highlights an interesting aspect of India’s evolving payment system.
While digital payments such as UPI are transforming how Indians transact, cash remains important for millions of people and businesses.
Modernising physical currency can therefore complement India’s digital-payment expansion rather than compete with it.
If the field trial succeeds, India could eventually move towards greater use of polymer banknotes, potentially beginning with heavily circulated lower denominations.
For now, however, the next step is testing.
The performance of the 2 billion polymer ₹10 and ₹20 notes in real-world circulation will determine whether India’s experiment with plastic currency becomes a permanent feature of the country’s monetary system.
