India’s Polymer Currency Push

India is moving closer to a new currency era, bringing together banknote innovation and domestic polymer manufacturing.

The government has approved RBI’s proposal to field-test one billion ₹10 and one billion ₹20 polymer banknotes, with broader introduction dependent on successful trials.

Unlike conventional notes, polymer banknotes use security-grade BOPP (biaxially oriented polypropylene) substrates combined with specialised coatings, opacification, printing and advanced security features.

The economic advantage is durability. Polymer notes can potentially remain in circulation significantly longer, reducing replacement frequency and improving the lifecycle economics of physical currency.

RBI subsidiary BRBNMPL has already explored suppliers for security-grade polymer substrates, creating opportunities for specialised Indian manufacturers and technology providers.

If adoption expands, India could develop an integrated ecosystem spanning BOPP substrates → security coatings → printing → authentication technologies → recycling.

The larger opportunity goes beyond currency. Domestic production of security-grade specialty polymers could create a new Make-in-India polymer-security industry, reducing import dependence while building capabilities in advanced materials and secure manufacturing.
