GS Paper 3 Currency Management, RBI Policy, Digital vs. Physical Cash Economy - Currency Management, RBI Policy, Digital vs. Physical Cash

UPI processed more than 24,000 crore transactions last year, yet the value of currency in circulation also kept climbing, crossing Rs 41 lakh crore. Two numbers that should be moving in opposite directions are rising together and the RBI's new push for polymer banknotes is a direct response to that contradiction.SUMMARY: The RBI's currency printing arm, Bharatiya Reserve Bank Note Mudran Private Limited (BRBNMPL), has invited global Expressions of Interest for polymer substrates with embedded security features, its most concrete step toward polymer banknotes since the idea was first floated in 2009. The move targets lower denominations, especially Rs 10 and Rs 20 notes, which see the highest handling frequency and replacement costs. It comes even as UPI processed over 24,000 crore transactions in FY2025-26 and currency in circulation simultaneously touched Rs 41.68 lakh crore, a pattern the RBI itself calls the "currency demand paradox."

Summary

The RBI's currency printing arm, BRBNMPL, has invited global Expressions of Interest for polymer banknote substrates, its most concrete step toward plastic currency since the original 2009 proposal, with bids due August 18, 2026.

Polymer notes last 2.5-4 times longer than cotton-paper notes but cost 30-60% more to produce, with lower denominations like ₹10 and ₹20 likely to see the first rollout given their high replacement frequency. The move comes despite India's "currency demand paradox" — cash in circulation has grown past ₹41.68 lakh crore even as UPI processes over 24,000 crore transactions annually — raising questions about the economic case for large-scale polymer adoption amid volatile petrochemical prices.

WHY IN NEWS FOR UPSC & STATE PCS

BRBNMPL's Expression of Interest, with bids due by August 18, 2026, marks the first serious administrative movement on polymer currency in over a decade after the original 2012 pilot in five cities was shelved. RBI Governor Sanjay Malhotra confirmed last month that polymer currency is again under active consideration, reviving a debate about whether investing in more durable physical cash makes sense at a moment when digital payments dominate retail transactions.

Standard News

Who Actually Needs Rs 10 and Rs 20 Notes to Last Longer

The aggregate story is UPI's triumph - 24,000 crore transactions, 85% of retail digital payments. But zoom into which notes the RBI is actually targeting for polymer substitution and the story changes completely: it's Rs 10 and Rs 20 notes, not the Rs 500 note that dominates value in circulation.

Who Is Still Handling These Notes Every Day Rs 10 and Rs 20

notes are the currency of the vegetable vendor, the auto fare, the tea stall, the informal daily-wage transaction - exactly the segment of the economy where UPI penetration remains thinnest, either because of poor rural digital connectivity or because small daily cash transactions don't route through a QR code.

These are also the notes that get handled most, get soiled fastest and cost the RBI disproportionately to keep replacing. The currency demand paradox isn't a mystery once you separate value from volume: Rs 500 notes dominate the value of currency in circulation, but Rs 10 and Rs 20 notes dominate the physical wear-and-tear cost, because they pass through the most hands in the informal economy that UPI hasn't fully reached.

The Real Trade-Off the RBI Is Weighing This is

why polymer makes narrow economic sense even in a UPI-dominated economy: it isn't a bet against digital payments, it's a bet on reducing the lifecycle cost of serving the cash-dependent segment that digital payments haven't yet absorbed.

But the mechanism has a real vulnerability - polymer substrate is derived from polypropylene and India imports roughly a fifth of its domestic polypropylene needs. West Asian volatility that raises crude prices flows directly into the cost of a note meant to save money, precisely for the lowest-income cash users this policy is meant to serve.

If petrochemical prices spike, the RBI's durability bet could turn into a cost bet that undermines its own logic, particularly for denominations already operating close to face value on production cost. The exam-relevant insight: the "digital versus cash" framing misses the actual question.

This isn't paper versus polymer as a binary choice - it's whether India can make its shrinking-but-still-essential cash economy, concentrated in the informal sector and low denominations, cheaper to serve without exposing that population to global petrochemical price risk.

Quick Facts

  • Polymer banknotes last 2.5 to 4 times longer than cotton-paper notes but cost 30-60% more to manufacture. India's currency printing cost was Rs 4,875 crore in FY2025-26 and the country destroys 20-24 billion soiled notes annually under its Clean Note Policy.

    UPI accounted for 85% of retail digital payments in FY2025-26. Currency in circulation rose from about Rs 16-17 lakh crore a decade ago to over Rs 41 lakh crore in FY2025-26, even as the currency-to-GDP ratio has stayed above 11% since bottoming at 8.7% during 2016-17 demonetisation.

Environment - River Interlinking, Rehabilitation, Forest/Tribal Land Displacement Mannu Yadav clutches her Aadhaar card as she speaks, because it is the only document she has to prove she exists in a place where, according to the official survey records, she does not. Her husband drowned in the Ken decades ago; the compensation register that is supposed to recognise her family has no line for her at all.SUMMARY: Construction on India's first inter-basin river-linking project, the Rs 44,605-crore Ken-Betwa Link, has entered a decisive phase, forcing nearly 2,000 families across 10 villages in Madhya Pradesh to relocate before the Daudhan dam's reservoir submerges their land. Official data shows rehabilitation is close to complete - Chhatarpur district has disbursed roughly Rs 750 crore and released over 96% of rehabilitation payments. Yet dozens of families in Daudhan, Palkhua and Sukwaha say they were never counted in the survey, leaving them without compensation and unable to prove, on paper, that they belong to the villages they are being asked to abandon. Environment - Wildlife Conservation vs. Hydroelectric Development, EIA Adequacy How does a critically endangered species, one with fewer than 250 individuals left on Earth, get left out of the very environmental assessment designed to catch exactly this kind of risk? The answer, for the white-bellied heron, comes down to where officials drew a line on a map.SUMMARY: The Forest Advisory Committee under the Union Environment Ministry has granted in-principle clearance to the 1,200-MW Kalai-II hydroelectric project on the Lohit River in Arunachal Pradesh, which will fell more than 33,000 trees. The project's environmental impact assessment did not include the white-bellied heron, a critically endangered species of which the Lohit basin holds an estimated 70% of India's entire population. State officials told the Forest Advisory Committee the bird was excluded because it had not been recorded within the project's narrow "diversion area." The Committee's clearance permits compensatory afforestation in Madhya Pradesh, more than a thousand kilometres from the Lohit basin.

Domestic Reform as Shock Absorber in Indian Foreign Policy Why do 1990-91 and 2026 keep rhyming so closely - a Gulf shock, a collapsing anchor power, a foreign policy establishment more sentimental than strategic?
