What is the 'cash paradox' in the Indian economy? Examine why rising digital transactions have not led to a proportional decline in cash in circulation.

The 'cash paradox' describes the co-existence of two apparently contradictory trends in India — a rapid expansion of digital payments alongside a continuing rise in currency in circulation (CIC). The paradox, on closer examination, is largely apparent rather than real.

The paradox stated

• UPI transaction volumes grew about 22.5% year-on-year in August 2026, with value up roughly 20%, yet CIC has not contracted correspondingly [3].
• RBI Deputy Governor Shirish Chandra Murmu holds that this is "no paradox": cash performs a dual role — a medium of transaction and a store of value — while digital modes substitute only the first [3].

Why CIC has not fallen proportionally

• Store-of-value demand: high-denomination notes are held as savings rather than spent, so hoarded cash is insulated from any shift in payment habits [1].
• Precautionary motive: RBI's Benchmarking India's Payment Systems records surges in cash demand during uncertainty — natural disasters and the COVID-19 pandemic [1].
• Structural cash dependence: the informal sector, agricultural trade, daily wages and thin-margin rural retail still settle largely in cash.
• Composition of digital growth: UPI has mainly displaced small-value person-to-person and person-to-merchant payments; high-value and unrecorded transactions remain cash-based.
• Measurement limitation: India's CIC-to-GDP ratio is high though CIC per person is low, which is why RBI itself calls CIC a sub-optimal indicator of actual cash payment usage [1].
• Policy design: zero MDR since January 2020, enabled through Section 10A of the Payment and Settlement Systems Act, 2007 and Section 269SU of the Income-tax Act, 1961, made digital acceptance frictionless without withdrawing the underlying demand for cash [2].

Thus the paradox dissolves once the two functions of money are separated — digital adoption is best judged by transaction volume and value, not by notes outstanding. Going forward, sustaining the less-cash economy will depend on calibrated pricing, such as the merchant-borne 0.4% MDR on high-value payments effective 15 October 2026 [3], and on measuring success through payment data rather than currency stock — advancing the Digital India goal of an inclusive, low-cost payments ecosystem.
