Despite the rapid growth of digital payments, India's physical currency circulation is still increasing at a double-digit pace. RBI Deputy Governor Shirish Chandra Murmu stated the central bank is launching trials for polymer-based ₹10 and ₹20 notes to improve durability and reduce long-term costs, starting in early fiscal year 2027-28.
India is experiencing a unique economic trend where the rapid adoption of digital payment methods has not slowed the public's demand for physical cash. According to RBI Deputy Governor Shirish Chandra Murmu, currency in circulation is continuing to grow at a double-digit rate, creating a complex forecasting environment for the central bank.
This persistent need for cash is particularly visible in rural regions, among older citizens, and within the small business sector. The high volume of banknotes—currently estimated at roughly 176 billion in circulation—places a significant burden on the central bank to manage production, distribution, and the replacement of soiled currency. Currently, the RBI manufactures between 28 billion and 30 billion new banknotes annually, while simultaneously disposing of approximately 21 billion damaged or soiled notes each year.
The Shift Toward Polymer Banknotes
To manage the high logistical and production costs associated with this massive volume, the RBI is exploring more durable alternatives to traditional paper notes. The central bank has announced a pilot project to introduce polymer-based currency for lower denominations. Specifically, the government has approved field trials for 1 billion banknotes each of the ₹10 and ₹20 denominations.
The RBI is currently initiating the procurement of polymer substrates and will conduct rigorous testing to ensure these notes perform well under India's varied climatic and usage conditions. These pilot notes are expected to enter circulation at the start of the 2027-28 fiscal year, provided that the initial trials and operational assessments are successful. During this trial phase, both the new polymer notes and the existing paper-based currency will remain in circulation concurrently.
Why This Matters for the Economy
The continued reliance on cash presents an ongoing challenge for the RBI in terms of currency management and cost efficiency. Polymer notes are generally more expensive to produce initially but are designed to last significantly longer than traditional paper currency. By increasing the lifespan of banknotes, the RBI aims to reduce the frequency of replacement and lower the overall cost of maintaining the currency supply.
For the economy, this move signifies an adaptive approach by the central bank. While digital infrastructure continues to expand, the RBI is acknowledging that physical cash remains a vital component of the Indian transaction ecosystem. Investors and market observers should monitor the success of these trials, as a positive outcome could lead to a broader rollout of polymer currency across higher denominations in the future. The ability of these notes to withstand heavy usage will be a key factor in determining if this transition helps the central bank successfully lower the long-term cost of maintaining the nation's cash supply.
