Direct Answer
Section 22:Sole right to issue bank notes in India.
Section 25:Dictates the design, form, and material (e.g., polymer) of notes.
Section 26:Legal tender character of notes.
Concept
Section 25 of the Reserve Bank of India Act, 1934, governs the design, form, and material of bank notes, requiring the Central Government’s approval based on the RBI Central Board’s recommendation
What quantity of polymer banknotes for each of the approved denominations has the government cleared for the initial field trials?
Direct Answer
1 billion pieces each
Concept
The field trial scale has been explicitly set at one billion pieces for each of the selected denominations (βΉ10 and βΉ20) to ensure a sufficiently large sample size across diverse conditions
Volume Calculation for Trial:Step 1: βΉ10 Denomination = 1,000,000,000 (One Billion) pieces.Step 2: βΉ20 Denomination = 1,000,000,000 (One Billion) pieces.Total Output: 2 Billion polymer notes will be injected into the trial ecosystem.
What is co-circulation?
Direct Answer
Co-circulation is the monetary policy strategy where newly introduced polymer notes will be accepted as legal tender simultaneously with the existing paper substrate-based notes
Concept
| New Polymer Notes | Active | Field Trial Phase |
| Existing Paper Notes | Active | Continued Regular Circulation |
What is the difference between Traditional Notes and Polymer Notes?
Direct Answer
Traditional Notes:Made of 100% cotton comber. Highly porous, absorbs moisture and dirt easily, leading to rapid deterioration.
Polymer Notes:Made of non-porous plastic film. Repels water and dirt, significantly extending the lifespan by 2 to 6 times.
Concept
Polymer banknotes are manufactured using a clear, non-porous plastic film (typically biaxially oriented polypropylene), fundamentally replacing the traditional cotton-paper mix
The field trials for the newly approved polymer banknotes are strategically planned across specific cities in India.
What is the primary scientific rationale for selecting these diverse locations?
Direct Answer
To evaluate the substrate's resilience across drastically different climatic and geographic zones
Concept
The RBI conducts currency field trials in cities representing diverse climatic zones to scientifically measure how environmental stress (heat, humidity, dust) affects the physical degradation of the new substrate
| High Humidity (Coastal) | Testing resistance to moisture absorption and fungal growth. |
| Extreme Heat (Arid) | Testing thermal stability to ensure the plastic film does not warp or melt. |
| Dust/Pollution (Urban) | Evaluating ink adhesion and smudge resistance on the non-porous surface. |
What is the difference between Cotton-Paper Limitations and Polymer Advantage?
Direct Answer
Cotton-Paper Limitations:Paper is fundamentally opaque. Creating a "window" requires physically punching a hole and gluing a plastic patch over it, creating a structural weakness.
Polymer Advantage:The base material is already clear plastic. The "window" is simply a designated area where the opaque base ink layers are intentionally omitted during printing.
Concept
A transparent window is a see-through section of a polymer banknote created by leaving a portion of the clear plastic substrate completely unprinted, serving as a highly effective anti-counterfeiting measure
What is the primary economic driver for replacing cotton notes with polymer?
Direct Answer
The primary economic driver for replacing cotton notes with polymer is the "lifespan multiplier"βthe extended duration the note can remain in active circulation before becoming unfit due to soiling or tearing
Concept
Cotton (1x)~1 YearPolymer (2.5x to 4x)~2.5 to 4 Years
What is end-of-life processing?
Direct Answer
End-of-life processing refers to the protocol a central bank follows when a banknote is deemed "unfit" for circulation and is permanently withdrawn and destroyed
Concept
| Cotton-Paper | Industrial Shredding | Compressed into solid blocks (briquettes) used for industrial heating or landfill. |
| Polymer | Granulation and Melting | Recycled into plastic pellets used for manufacturing items like compost bins and plumbing fittings. |
What is the difference between 1988 and 1996?
Direct Answer
1988:Australia issues the world's first polymer note (a $10 commemorative note for the bicentenary).
1996:Australia becomes the first country to transition entirely to polymer for all denominations.
2026 (Present):India initiates formal, large-scale field trials to test the viability of joining over 60 other nations using polymer.
Concept
The Reserve Bank of Australia (RBA), in collaboration with the Commonwealth Scientific and Industrial Research Organisation (CSIRO), invented and issued the worldβs first polymer banknotes
What is the difference between Kochi & Bhubaneswar and Jaipur?
Direct Answer
Kochi & Bhubaneswar:Tests extreme coastal humidity and moisture resistance.
Jaipur:Tests resilience against extreme arid heat and dust accumulation.
Shimla & Mysuru:Tests performance in cold, hilly terrains and moderate southern climates.
Concept
The RBI intentionally avoids selecting only major metropolitan hubs, instead choosing specific tier-2 and tier-3 cities that perfectly represent India’s extreme climatic variations
What is an opacifying layer?
Direct Answer
An opacifying layer is a specialized white ink applied to the clear Biaxially Oriented Polypropylene (BOPP) substrate to create a solid, non-transparent canvas for standard currency printing
Concept
Manufacturing Sequence:Step 1: Substrate – Clear plastic film is manufactured.Step 2: Opacification – White opacifying ink is applied on both sides (intentionally leaving gaps for the transparent security windows).Step 3: Printing – Traditional offset and raised intaglio inks are applied to the now-opaque areas.Step 4: Coating – A final clear protective varnish is applied to seal the ink.
When analyzing the economic viability of replacing traditional currency with polymer banknotes, how does the cost of polymer notes compare to cotton-paper notes?
Direct Answer
Polymer notes have a higher initial printing cost but a lower overall lifecycle cost.
Concept
The economic model of currency issuance distinguishes between the “Unit Cost” (cost to print one physical note) and the “Lifecycle Cost” (cost of keeping a denomination in circulation over a decade, including replacement cycles
| Initial Unit Cost | Low (Base Baseline) | High (~1.5x to 2x more expensive) |
| Replacement Frequency | High (Every ~1 year) | Low (Every ~3 to 4 years) |
| Net Lifecycle Cost | High (Constant re-printing) | Low (Massive long-term savings) |
What is the difference between Cotton-Paper Issue and Polymer Solution?
Direct Answer
Cotton-Paper Issue:Cotton absorbs human sweat, oil, and atmospheric moisture. This softens the fibers, causing the raised ink features to flatten out and disappear after a few months of active circulation.
Polymer Solution:Plastic is entirely non-porous and rigid. It repels moisture and oils, meaning the heavily embossed tactile dots/lines retain their sharp, raised structure for years.
Concept
Tactile features are raised geometric patterns (like lines or dots) printed using heavy intaglio ink on the edges of banknotes to help visually impaired individuals feel the denomination
What is Global Warming Potential (GWP)?
Direct Answer
Global Warming Potential (GWP) is a metric used in Life Cycle Assessments (LCA) to measure the total greenhouse gases emitted from the raw material extraction, printing, distribution, and disposal of a product
Concept
| Raw Materials | High (Land use, massive water for cotton, pesticides) | Moderate (Petrochemical derivative, but lightweight) |
| Distribution | High (Heavy weight, frequent shipping for replacement) | Low (Lighter weight, fewer shipments needed) |
| End of Life | Methane emissions if landfilled; ash if incinerated | Recycled into secondary plastic goods (Compost bins) |
