Polymer Banknotes in India

Context

Bharatiya Reserve Bank Note Mudran Private Limited, the Reserve Bank of India's currency printing subsidiary, invited global Expressions of Interest (EoI) to procure polymer substrate sheets for a pilot rollout of ₹10 and ₹20 polymer banknotes.

Overview of Polymer Banknotes in India

Definition & Technology

• Polymer banknotes are made from Biaxially Oriented Polypropylene (BOPP) instead of traditional cotton-rag paper.
• More than 60 countries, led by Australia, use polymer currency.

Purpose

• Improve durability, cleanliness, security, and circulation life while reducing the frequency of note replacement.

Key Data & Statistics

Durability

• Polymer banknotes last 2.5–4 times longer than paper banknotes.

Production Cost

• Initial manufacturing costs are 30–60% higher than paper currency.

Cash vs. Digital Payments

• The Unified Payments Interface (UPI) processes over 24,000 crore transactions annually, yet currency in circulation exceeds ₹41 lakh crore, with the Currency-to-Gross Domestic Product (GDP) ratio remaining above 12%.

Import Dependence

• India imports nearly 20% of its polypropylene requirement.

Advantages of Polymer Banknotes

Longer Lifespan

• Resistant to moisture, dirt, oils, and tearing, making them suitable for frequently used low-denomination notes.

Lower Lifecycle Cost

• Reduced replacement frequency lowers printing, transportation, sorting, and disposal costs.

Enhanced Security

• Supports advanced security features such as transparent windows, colour-shifting inks, metallic overlays, and shadow images, making counterfeiting more difficult.

Environmental Benefits

• Longer circulation life reduces overall production and transportation, lowering lifetime carbon emissions.

Key Challenges

High Initial Cost

• Specialized polymer substrates and security features significantly increase production costs.

Petrochemical Dependence

• Polypropylene prices depend on global crude oil markets and import supply chains.

Infrastructure Upgradation

• Automated Teller Machines (ATMs), currency sorting machines, and cash vending machines require recalibration.

Growth of Digital Payments

• Increasing adoption of the Unified Payments Interface (UPI) and the Central Bank Digital Currency (e-Rupee) may gradually reduce long-term demand for physical currency.

Way Forward

Phased Pilot Rollout

• Introduce polymer banknotes in ₹10 and ₹20 denominations across different climatic regions.

Domestic Manufacturing

• Expand indigenous polypropylene refining and polymer substrate manufacturing to reduce import dependence.

Recycling Infrastructure

• Develop dedicated facilities to recycle retired polymer banknotes into industrial plastic products.

Balanced Currency Strategy

• Integrate polymer currency with expanding digital payment systems for efficient and sustainable cash management.

Conclusion

Polymer banknotes offer greater durability, stronger security, and lower long-term costs despite higher initial investment. A phased rollout, domestic manufacturing, and integration with digital payment infrastructure can help build a secure, efficient, and sustainable currency system in India.
