RBI works to give banknotes a longer lease on life

The Reserve Bank of India (RBI) is actively researching methods to prolong the lifespan of banknotes, as reported in the central bank’s monthly bulletin published on Tuesday. According to RBI Deputy Governor Shirish Chandra Murmu, the bank is investigating various approaches, such as applying surface coatings to banknote substrates and employing polymer notes for lower denominations.

Murmu discussed these potential measures in an article titled "Strengthening Collaboration to Preserve Sovereignty: Collaborative Cash Ecosystems - Global Strategies to Preserve Trust and Sovereignty."

Currently, there are 176 billion banknotes circulating in India, compared to approximately 56 billion US dollar bills and 30 billion euro banknotes in circulation at the end of the previous year. The Indian government has already granted approval for the central bank to introduce polymer notes in the ₹10 and ₹20 denominations for field trials, despite initially announcing this plan over a decade ago. However, there is no intention to replace existing paper-based Indian currency with RBI plastic notes.

Murmu highlights the paradox of India's cash system, noting that currency in circulation continues to expand at double-digit rates, even as the share of cash in individual transactions declines due to the increasing adoption of digital payments. This combination makes it challenging to predict future demand, complicating planning for production and distribution capacity.

The central bank is also striving to minimize the environmental impact of the cash cycle by optimizing its distribution network for efficiency and improving the disposal process of "banknote briquettes."

When asked if the proposed RBI plastic notes would impact digital payments, Pankaj Chaudhary, Minister of State for Finance, stated that the currency proposal is still in the preliminary stage. He emphasized that any potential effects can only be evaluated after regular issuance begins. Chaudhary also clarified that physical banknotes and digital payment systems will coexist, with both remaining accessible to the public.

The government has made it clear that RBI polymer notes will circulate alongside existing paper-substrate Indian currency, with no plans to entirely replace paper banknotes with polymer-based notes.
