Polymer Banknotes in India

The RBI is attempting to introduce Polymer Banknotes in India as a step towards a durable and secure currency. Read here to learn more.

The Reserve Bank of India’s (RBI) wholly-owned subsidiary, Bharatiya Reserve Bank Note Mudran Private Limited (BRBNMPL), has invited global Expressions of Interest (EoI) for the supply of opacified polymer substrate sheets with embedded security features.

The move signals the RBI’s renewed efforts to introduce polymer banknotes in India, aiming to improve the durability, security, and efficiency of currency management.

What are Polymer Banknotes?

Polymer banknotes are currency notes manufactured using Biaxially Oriented Polypropylene (BOPP), a specially engineered plastic substrate, instead of the conventional cotton-rag paper used in most banknotes.

Polymer notes were first introduced by Australia in 1988, and today more than 60 countries, including Canada, New Zealand, the United Kingdom, Singapore, Vietnam, Romania, and Mexico, have adopted polymer currency either fully or partially.

They are designed to provide:

• Longer circulation life
• Greater resistance to wear and tear
• Enhanced protection against counterfeiting
• Lower lifecycle costs
• Improved cleanliness and hygiene

RBI’s Polymer Currency Initiative

• The RBI has periodically explored the introduction of polymer banknotes to modernise India’s currency system.
• The latest initiative involves procuring opacified polymer substrate sheets embedded with advanced security features for pilot production.

Executing Agency

The project is being undertaken through:

• Bharatiya Reserve Bank Note Mudran Private Limited (BRBNMPL)

which is the RBI’s currency printing subsidiary responsible for printing Indian banknotes.

Features of Polymer banknotes

Longer Lifespan

Polymer notes typically last 2.5 to 4 times longer than conventional paper currency because they:

• Resist tearing
• Do not absorb moisture
• Remain cleaner in circulation
• Withstand repeated handling

This makes them particularly suitable for low-denomination notes that change hands frequently.

Higher Initial Production Cost

• Polymer banknotes cost approximately 30-60% more to manufacture than paper notes.
• For lower denomination notes, printing costs may account for 20-24% of the note’s face value.
• However, their longer service life substantially reduces replacement costs over time.

Cash Remains Important Despite Digital Payments

India has witnessed explosive growth in digital payments.

• UPI now processes over 24,000 crore transactions annually.
• It accounts for nearly 85% of retail digital payments.

Despite this digital revolution, India’s Currency-to-GDP ratio remains above 11%, indicating that cash continues to play an important role in the economy.

Import Dependence

• India currently imports around 20% of its polypropylene requirements, exposing polymer note production to global supply-chain disruptions and crude oil price volatility.

Advantages of Polymer Banknotes

Superior Durability

Unlike cotton paper, polymer notes:

• Resist folding damage
• Do not tear easily
• Withstand moisture, sweat, oils, and dirt
• Maintain print quality for longer periods

This significantly increases their circulation life.

Lower Lifecycle Cost

Although manufacturing costs are higher initially, fewer replacements lead to savings in:

• Printing
• Transportation
• Storage
• Currency destruction
• Distribution

This reduces the overall cost of currency management for the RBI.

Enhanced Security Features

Polymer substrates enable sophisticated anti-counterfeiting technologies that are difficult to replicate.

These include:

• Transparent see-through windows
• Colour-shifting inks
• Metallic foils
• Holographic strips
• Micro-text
• Laser engraving
• Complex optically variable devices

These features significantly reduce the risk of counterfeit currency.

Cleaner and More Hygienic

Polymer notes absorb significantly less:

• Dust
• Moisture
• Oils
• Bacteria

Consequently, they remain cleaner during circulation, improving public hygiene.

Lower Environmental Impact Over Time

Although polymer production is energy-intensive, studies by The Energy and Resources Institute (TERI) indicate that polymer notes have a lower lifetime carbon footprint because they:

• Require fewer replacements
• Reduce transportation frequency
• Lower overall manufacturing requirements

Challenges Associated with Polymer Currency

High Initial Investment

• The biggest challenge is the substantially higher production cost of polymer substrates and advanced security technologies.
• This increases the upfront expenditure for the RBI.

Dependence on Petrochemicals

Polymer notes are derived from polypropylene, a petroleum-based product.

Consequently, production costs remain vulnerable to:

• Crude oil price fluctuations
• Global petrochemical supply disruptions
• Geopolitical tensions

ATM and Banking Infrastructure Upgradation

Introducing polymer notes would require modifications to:

• ATMs
• Cash sorting machines
• Currency counting equipment
• Vending machines
• Currency processing systems

Banks and cash logistics companies may incur considerable transition costs.

Growing Digital Payments

India is rapidly adopting:

• UPI
• Aadhaar-enabled payments
• e-Rupee (CBDC)

Hence, the demand for physical currency may gradually moderate, raising questions about the long-term economic justification for large investments in polymer currency infrastructure.

Recycling Challenges

• Unlike cotton-based notes, polymer banknotes require specialised recycling facilities to ensure environmentally sound disposal after retirement from circulation.

Environmental Perspective

Compared to paper notes:

Advantages

• Longer lifespan
• Reduced paper consumption
• Lower transportation emissions
• Lower lifetime carbon emissions

Concerns

• Petroleum-based raw material
• Specialised recycling requirements
• Plastic waste management

A well-developed circular recycling ecosystem is therefore essential.

Way Forward

Pilot Introduction

Initially, introduce polymer notes only in:

• ₹10 denomination
• ₹20 denomination

These notes experience the highest circulation frequency and would generate maximum lifecycle savings.

Domestic Manufacturing

To reduce dependence on imported polymer substrates, expand India’s polypropylene manufacturing capacity under initiatives such as:

• Make in India
• Atmanirbhar Bharat

Develop Recycling Infrastructure

Establish dedicated facilities capable of recycling retired polymer notes into:

• Industrial plastic products
• Construction materials
• Utility goods

Upgrade Currency Infrastructure

To ensure smooth adoption of polymer notes, gradually modernise:

• ATMs
• Currency sorting systems
• Cash logistics infrastructure

Integrate with Digital Currency Strategy

Balance investments in physical cash with the expansion of:

• UPI
• Central Bank Digital Currency (e₹)
• Digital financial inclusion

This will help in creating an efficient and future-ready monetary ecosystem.

Conclusion

The RBI’s renewed initiative to introduce polymer banknotes represents an important step toward modernising India’s currency management system.

Polymer notes offer significant advantages in terms of durability, security, hygiene, and long-term cost efficiency, particularly for low-denomination currency that experiences frequent circulation.

While higher production costs, dependence on imported polypropylene, infrastructure upgrades, and recycling challenges remain important concerns, carefully phased implementation supported by domestic manufacturing and robust recycling mechanisms can maximise their benefits.

As India simultaneously expands digital payments and the e-Rupee ecosystem, polymer currency can complement a modern, secure, and resilient monetary framework suited to the needs of a rapidly evolving economy.
