Few developments in modern economics are as intriguing as India’s evolving monetary landscape. Conventional wisdom would suggest that the spectacular rise of digital payments should steadily diminish the role of physical cash. Yet India presents a very different picture. Digital transactions have expanded exponentially, currency in circulation has continued to rise to record levels, and the overall velocity of money has remained remarkably stable.
Rather than representing an economic contradiction, these parallel developments reveal a deeper structural transformation. India is not becoming a cashless economy. Instead, it is evolving into a sophisticated dual-track monetary system in which digital payments and physical currency increasingly perform different but complementary roles. Digital platforms have become the preferred medium for everyday transactions, while cash continues to serve as a trusted store of value, a precautionary reserve, emergency liquidity and an indispensable instrument for significant segments of the informal economy.
This evolving monetary architecture deserves closer attention because it challenges several long-held assumptions about the relationship between technology, money and economic development.
Drawing upon macroeconomic indicators and the Reserve Bank of India’s (RBI) findings, the evidence suggests that rising cash demand should not automatically be interpreted as evidence of economic backwardness or an expanding shadow economy. Instead, it reflects the changing ways in which households, businesses and institutions use different forms of money in an increasingly digital economy.
A Monetary Puzzle That Becomes Clearer
Few countries have embraced digital payments as rapidly or as comprehensively as India. The Unified Payments Interface (UPI), together with internet banking, mobile wallets and debit and credit cards, has transformed the country’s payment ecosystem. Millions of transactions that once depended upon cash are now completed instantly through digital platforms.
Yet this remarkable digital revolution has unfolded alongside another equally significant trend. Currency in circulation has continued to grow steadily year after year, exceeding ₹41 lakh crore by 2025-26 compared with around ₹16-17 lakh crore a decade earlier. Meanwhile, the income velocity of Broad Money (M3) has remained broadly stable.
At first sight, these developments appear contradictory. If digital payments are steadily replacing cash, why does demand for physical currency continue to increase? If the stock of currency has expanded so substantially, why has the velocity of money not declined sharply? Does higher currency in circulation necessarily imply a growing volume of unaccounted or illicit money?
The evidence suggests otherwise. The apparent paradox disappears once we recognise that digitalisation has not eliminated the need for cash; it has fundamentally altered its economic role. Digital payments increasingly dominate transactional activity, while physical currency has assumed greater importance as a store of value, a precautionary asset and a source of liquidity during periods of uncertainty.
The Remarkable Stability Beneath Rapid Change
One of the most revealing indicators of India’s monetary transformation is the income velocity of Broad Money (M3), measured as nominal GDP divided by the total money supply. Despite enormous structural changes over the past decade, this ratio has remained strikingly stable.
According to RBI data and official national accounts, M3 velocity stood at around 1.14 in 2015-16, increased modestly before the pandemic, dipped temporarily during the COVID-19 period as precautionary savings rose and economic activity slowed, and recovered to around 1.16 by 2025-26.
Such limited variation is remarkable when viewed against the profound changes taking place across the economy. Financial inclusion expanded dramatically through Jan Dhan accounts, digital infrastructure penetrated rural India, internet connectivity widened rapidly, and digital payment volumes grew at an unprecedented pace. Yet the broad relationship between money supply and nominal economic output remained firmly anchored.
This stability carries an important implication. Monetary expansion has broadly kept pace with economic growth, suggesting that India’s monetary system has adapted successfully to technological change without sacrificing macroeconomic stability.
The Continuing Relevance of Cash
The steady expansion of currency in circulation tells an equally important story. Conventional monetary thinking might regard a more than 150 per cent increase in currency over a decade as evidence of declining financial efficiency or excessive liquidity. India’s experience points in the opposite direction.
Throughout this period, nominal GDP expanded robustly, financial inclusion deepened, bank balance sheets strengthened and digital payment volumes established global benchmarks. Cash did not grow at the expense of digitalisation; both expanded simultaneously because they increasingly served different economic purposes.
In other words, India is not witnessing a contest between paper currency and digital payments. It is witnessing a functional reallocation of monetary roles. Digital technology has become the preferred mechanism for routine transactions, while cash continues to provide resilience, flexibility and confidence in circumstances where its unique attributes remain valuable.
The temporary disruptions caused by demonetisation in 2016 and the COVID-19 pandemic further reinforce this conclusion. Demonetisation briefly compressed currency in circulation, artificially raising measured cash velocity, while the pandemic encouraged precautionary cash holdings and temporarily lowered velocity. Once these exceptional shocks subsided, the underlying monetary relationships broadly returned to their long-term trajectories, underlining the resilience of India’s evolving monetary architecture.
Digital Payments Transform Transactions, Not the Money Supply
A common misunderstanding is that the spectacular growth of UPI transactions should automatically accelerate the macroeconomic velocity of money. In reality, the standard measures of monetary velocity are not designed to capture the operational intensity of digital payment systems. They measure the relationship between the stock of money and nominal economic output, not the number of times the same deposits are transferred electronically.
Digital payment platforms such as UPI do not create additional money; they enable existing bank deposits to circulate more efficiently. A single deposit balance may facilitate numerous transactions within a day while remaining part of the same measured money stock. Consequently, an explosion in digital payment volumes does not necessarily result in a corresponding increase in measured monetary velocity.
The RBI’s analytical assessments reinforce this distinction. They suggest that digital payments have largely replaced routine, low-value cash transactions without diminishing the public’s preference for holding physical currency. Instead, cash has increasingly assumed different functions—as a reliable store of value, a precautionary reserve and an important source of liquidity for households, small businesses and the informal economy. Rising household incomes, expanding financial inclusion, direct benefit transfers and the continuing importance of cash-intensive local markets have all contributed to sustained demand for currency. Digital innovation has therefore not displaced cash; it has redefined its role.
Rethinking the Relationship Between Cash and Black Money
Perhaps no misconception has proved more persistent than the belief that rising currency in circulation necessarily reflects an expanding shadow economy. Such a conclusion finds little support in the broader macroeconomic evidence.
Cash continues to possess characteristics that digital payments cannot fully replicate. It functions without internet connectivity, electricity or technological infrastructure, involves no transaction charges, provides immediate settlement and remains universally accepted. These qualities continue to make cash indispensable for millions of households, particularly in rural areas and across large segments of the informal economy.
Behavioural factors also matter. The experience of demonetisation followed by the COVID-19 pandemic strengthened the precautionary demand for cash. Many households and micro-enterprises now regard physical currency as an essential financial buffer during periods of uncertainty. In addition, government pensions, agricultural support payments and direct benefit transfers credited into bank accounts are frequently withdrawn as cash and subsequently circulate through village and local markets before returning to the banking system.
More importantly, if illicit financial activity were the principal driver of rising currency demand, one would expect significant instability in cash velocity. The evidence points in the opposite direction. Cash velocity has remained broadly stable for nearly a decade, suggesting that the expansion of currency reflects structural economic factors—rising incomes, demographic growth, expanding economic activity and rational financial behaviour—rather than a systematic increase in unaccounted wealth.
This distinction is particularly important. A higher demand for cash, by itself, should not be interpreted as evidence of more black money. Correlation should not be mistaken for causation.
Understanding the Two Measures of Monetary Velocity
A clearer understanding of India’s monetary evolution also requires distinguishing between cash velocity and the velocity of Narrow Money (M1).
Cash velocity, measured as nominal GDP divided by currency in circulation, has remained remarkably stable at around 8.3 during the past decade. This stability indicates that physical currency continues to circulate through the economy at a broadly unchanged pace despite the rapid expansion of digital payments. Far from becoming redundant, cash continues to perform stable and well-defined economic functions.
The behaviour of M1 velocity tells a different story. M1 comprises currency in circulation together with demand deposits. As financial inclusion has expanded through Jan Dhan accounts, mobile banking and greater access to formal financial services, demand deposits have grown faster than nominal GDP.
Consequently, the calculated velocity of M1 has shown a gradual structural decline.
This decline should not be viewed as evidence of weakening monetary efficiency. Rather, it reflects the success of financial inclusion and the increasing integration of households and businesses into the formal banking system. Put differently, the moderation in M1 velocity is largely a consequence of more people holding larger transaction balances within banks, not of reduced economic dynamism.
Towards a More Resilient Monetary Ecosystem
India’s evolving monetary landscape offers one of the most compelling illustrations of how technological innovation can reshape, rather than replace, established monetary institutions. The coexistence of world-leading digital payment systems with steadily expanding currency in circulation is not an economic contradiction. It is evidence of a monetary system adapting to changing needs while preserving stability.
Three broad conclusions emerge from this experience. First, the stability of Broad Money (M3) velocity indicates that monetary expansion has remained broadly aligned with the growth of nominal GDP. Second, the sustained stability of cash velocity confirms that physical currency continues to perform indispensable economic functions even as digital payments dominate routine transactions. Third, the gradual moderation in M1 velocity reflects deepening financial inclusion and the growing role of formal banking rather than any weakening of economic activity.
The broader lesson extends beyond India. As economies become increasingly digital, the future is unlikely to belong to a purely cashless world. Instead, it is more likely to be characterised by diversified monetary ecosystems in which different forms of money coexist because they fulfil different economic purposes.
India’s monetary transformation reminds us that technological progress does not necessarily render established institutions obsolete; more often, it redefines their purpose. The real story is therefore not the triumph of digital payments over cash. It is the emergence of a more resilient, inclusive and adaptive monetary architecture in which both coexist, each performing the functions it serves best. In that sense, India’s evolving dual-track monetary system may well become one of the defining monetary innovations of the digital age.
