India’s familiar ₹10 and ₹20 notes are set for their biggest material change in decades. The government has approved an RBI proposal to introduce one billion polymer notes in each denomination, raising an immediate question for millions of people: What will happen to the paper notes already in your wallet?

Finance Minister Nirmala Sitharaman informed Rajya Sabha that the RBI had submitted the proposal under Section 25 of the RBI Act, 1934, following its Central Board’s recommendation.

Why is India changing to polymer notes?

The main reason is durability. Lower-denomination notes change hands frequently and become dirty, torn or unfit faster than high-value notes. ₹10 and ₹20 notes together account for almost one-fourth of banknotes in circulation by number, but only around 1.3 per cent of their total value.

Polymer notes use a thin, flexible synthetic material rather than the cotton-based paper used for Indian currency. They resist moisture, dirt and routine wear better, potentially reducing replacement, transportation and processing costs over their life cycle despite a higher initial manufacturing cost.

Polymer also permits transparent windows, holographic elements and raised printing that can make counterfeiting harder. The trial will test its performance in India’s heat, humidity, dust, cash-processing machines and varied retail conditions.

International experience supports some of these advantages. Polymer notes are used in countries including Australia, Canada and the United Kingdom, where central banks have reported longer note life and improved resistance to counterfeiting. Bank of England

What will happen to existing ₹10 and ₹20 notes?

Nothing immediate. The government has explicitly stated that polymer notes are proposed to circulate alongside paper notes. There is no proposal to replace all paper currency with polymer currency.

Existing ₹10 and ₹20 paper notes will continue to be legal tender. People will not have to deposit them, exchange them at banks or spend them before a deadline. No withdrawal date, exchange window or restriction on holding these notes has been announced. The Indian Express

Damaged paper notes will continue returning through the normal currency-cleaning process: notes fit for use can recirculate, while unfit notes are removed. Polymer notes would be added gradually—not exchanged overnight for every paper note.

When will polymer notes enter circulation?

RBI Governor Sanjay Malhotra has said the central bank is targeting the beginning of the next financial year, FY2027–28, if everything proceeds according to plan. That indicates a possible rollout around April 2027, but it is a target rather than a guaranteed launch date. The New Indian Express

The RBI must procure the polymer substrate, print the notes and test cash-processing equipment and public handling. The final design, trial locations and exact launch date have not been announced.

If field trials reveal problems, the schedule could be changed or wider issuance reconsidered. India planned a smaller polymer-note experiment more than a decade ago, including ₹10 trials in cities with different climates, but it did not progress because of technical issues.

Is this another demonetisation?

No. Demonetisation means withdrawing the legal-tender status of existing currency, as happened with the old ₹500 and ₹1,000 notes in November 2016. The present decision does not invalidate any denomination.

There will be no overnight cancellation, compulsory bank deposits, cash-withdrawal restrictions or exchange queues under the plan announced so far. The value of a ₹10 or ₹20 note will remain unchanged whether it is printed on paper or polymer.

Citizens should ignore social-media messages claiming that all paper notes are being withdrawn. Unless the RBI issues a separate official notification, current paper notes remain valid. This initiative is a trial of a more durable currency material—not a recall of Indian banknotes.
