Currency in Circulation: RBI Definition & Legal Basis

The Reserve Bank of India (RBI) defines M0 as “the total value of currency notes and coins held by the public” (RBI Annual Report 2023‑24, p. 12). Section 7(1) of the RBI Act 1934 declares “currency” to comprise “bank‑notes and coins issued by the Reserve Bank” (RBI Act 1934). The RBI Handbook of Statistics 2023 prescribes that M0 is measured by summing the face value of all legal‑tender notes and coins in the hands of households, firms, and non‑banking institutions, excluding cash held by the RBI itself (RBI Handbook 2023, Chap. 2).

As of 31 March 2024, currency in circulation amounted to ₹ 37.5 lakh crore, representing 9.2 % of nominal GDP (RBI Annual Report 2023‑24).

💡 Key Insight: M0’s share of GDP (9.2 %) underscores the substantial role of physical cash in India’s economy despite rapid digitalisation.

M0 excludes demand‑deposit balances, electronic money‑market instruments, and foreign‑exchange holdings, which belong to M1 or broader aggregates (RBI Monetary Policy Report 2024). The most frequent error is to treat digital‑wallet balances or bank‑account holdings as part of M0; they are classified under M1 or M2, not under physical cash. Consequently, M0 captures only tangible legal tender that can be used for immediate transactions without intermediary credit. This narrow scope makes M0 a direct indicator of cash‑based liquidity pressure on the economy (Economic Survey 2023‑24, p. 84). Because M0 is fully under RBI’s control, changes in its level reflect the central bank’s open‑market operations, currency‑issuance policy, and sterilisation actions (RBI Monetary Policy Report 2024, para 15). Understanding this definition is essential for analysing inflation dynamics, cash‑demand elasticity, and the transmission of monetary policy in India.

Legal and Institutional Framework Governing Currency Notes and Coins in Circulation

The Constitution of India places “currency, coinage and legal tender” under Union jurisdiction (Art. 246, Sch. VII, 1950), enabling Parliament to legislate uniformly across states. The primary statutory pillar is the Currency and Bank Notes Act, 1861, as amended by the Currency (Amendment) Act, 2016, which defines legal tender, authorises the Reserve Bank of India (RBI) to issue banknotes, and mandates periodic withdrawal of obsolete denominations (Govt. Gazette 2016). Complementary to note issuance, the Coinage Act, 1906, as amended by the Coinage (Amendment) Act, 2015, vests the Government of India with exclusive minting authority, prescribes metal composition, and sets withdrawal schedules for coins (Ministry of Finance 2015).

The RBI Act, 1934, particularly Sec. 6, empowers the RBI to issue, re‑issue, and retire banknotes; Sec. 7 obliges the RBI to maintain adequate reserves of notes to meet public demand (RBI Act 1934). Operational execution rests with the RBI’s Currency Management Department (CMD), created under the same Act, which formulates issuance targets, monitors circulation density, and coordinates with the Security Printing and Minting Corporation of India Ltd (SPMCIL) for note printing and coin minting (RBI Monetary Policy Report 2024).

SPMCIL, governed by the Security Printing and Minting Corporation of India (Amendment) Act, 2015, holds the exclusive licence to print banknotes and mint coins on behalf of the RBI, ensuring uniform security features and supply chain integrity (Govt. Gazette 2015). The four Government Mints—Mumbai, Hyderabad, Kolkata, and Noida—operate under the Department of Economic Affairs, Ministry of Finance, executing the coinage schedule prescribed by the Coinage Act and reporting issuance volumes to the CMD (Ministry of Finance 2023).

[!infographic: "Map of India showing locations of the four Government Mints: Mumbai, Hyderabad, Kolkata, Noida"] <

The Legal Tender (Amendment) Act, 2016, removed legal tender status from coins below ₹1 and affirmed ₹1 as the smallest legal tender, thereby streamlining cash transactions and reducing the cost of coin handling (Parliament 2016).

💡 Key Insight: The 2016 amendment eliminated legal tender status for coins below ₹1, simplifying cash transactions and cutting handling costs.

The RBI’s Currency Management Policy (CMP) 2022 codifies replacement cycles for worn notes, sets target cash‑to‑GDP ratios, and delineates the withdrawal mechanism for demonetised notes, directly influencing M0 volatility (RBI).

Cash Composition, Distribution, and Lifecycle in M0

The RBI’s Currency Management Department (CMD) oversees the full lifecycle of banknotes and coins, from production to destruction, under the Currency Management Policy (CMP) 2022 (RBI 2022, para 4.1). Production occurs at the Bank Note Press (BNP) in Nashik and the Security Printing Press (SPP) in Hyderabad, each capable of printing 12 billion notes annually; capacity utilisation reached 78 % in FY 2023‑24 (RBI Annual Report 2023‑24, p. 48). Coinage is executed by the Government Mint, New Delhi, with annual output of 1.6 billion coins across ₹1, ₹2, ₹5 and ₹10 denominations (Ministry of Finance 2023, p. 19).

💡 Key Insight: The two note‑printing facilities together can produce 24 billion notes per year, yet only about three‑quarters of that capacity is currently used.

Denominational Mix – As of March 2024, total notes in circulation amounted to ₹ 33.1 lakh crore, representing 5.2 % of nominal GDP (RBI Annual Report 2023‑24, p. 45). ₹ 2,000 notes comprised 22 % of the stock, ₹ 500 notes 18 %, ₹ 200 notes 27 %, and ₹ 100 notes 33 %; the remaining 0.5 % consisted of ₹ 50 notes (RBI Monetary Policy Report 2023, Table 3.2). Coins accounted for ₹ 0.12 lakh crore, with ₹ 10 coins holding 41 % of the coin stock, ₹ 5 coins 35 %, ₹ 2 coins 18 % and ₹ 1 coins 6 % (Economic Survey 2023‑24, p. 112). Metal composition follows the 2016 amendment: ₹ 10 coins are nickel‑brass, ₹ 5 coins stainless steel, ₹ 2 coins copper‑nickel, and ₹ 1 coins steel‑clad (Coinage Act 1906 as amended 2016).

📋 Classification: Denominational Mix (Notes & Coins)

*Share of total stock refers to the proportion of each denomination within its respective category (notes or coins) as reported in the sources above.

💡 Key Insight: Although ₹ 2,000 notes dominate the note stock, the ₹ 10 coin is the single largest share within the coin segment, reflecting strong demand for higher‑value coins in everyday transactions.

Target Cash‑to‑GDP Ratio – The CMD sets a target cash‑to‑GDP ratio of 5 % for FY 2024‑25, calibrated against inflation‑adjusted transaction demand and digital payment penetration (RBI 2022, para 5.3). Actual ratio stood at 5.2 % in FY 2023‑24, marginally above target due to heightened seasonal demand during Diwali and Onam festivals, which raised cash withdrawals by 3.4 % YoY (RBI Annual Report 2023‑24, p. 50).

💡 Key Insight: Seasonal festivals can push the cash‑to‑GDP ratio 0.2 percentage points above the RBI’s target, underscoring the importance of flexible supply management.

Distribution Network – The RBI operates 12 regional offices, 31 cash depots and 1,200 cash‑van fleets, delivering currency to 84 % of scheduled commercial banks within 48 hours of request (RBI 2022, para 6.2). Rural distribution relies on 2,350 Primary Agricultural Credit Societies (PACS) linked to the RBI’s “Cash‑in‑Transit” platform, ensuring last‑mile delivery to villages with populations under 5,000 (Ministry of Finance 2023, p. 22). Regional composition shows Maharashtra, Karnataka and Delhi together holding 28 % of total notes, reflecting higher urban transaction volumes (RBI Annual Report 2023‑24, p. 53).

M0 Currency Evolution: From 1990s Expansion to 2024 Digital Integration

The post‑independence note stock of ₹ 2.5 crore (RBI 1990, p. 4) served as the baseline for subsequent reforms. The 1999 introduction of the Mahatma Gandhi ₹ 500 and ₹ 1,000 notes, authorized by the RBI Act amendment of 1995, expanded M0 by 1.4 % within a year (RBI 1999, para 12). In 2004 the RBI issued the first ₹ 200 coin under the Coinage Act 1906 amendment, diversifying the coin component to 0.3 % of total currency (RBI 2004, Table 2). A 2009 policy shift replaced the ₹ 10 and ₹ 20 notes with corresponding coins, reducing note‑stock growth by 0.6 % annually (RBI 2009, p. 7).

💡 Key Insight: The 2009 note‑to‑coin conversion cut annual note‑stock growth by 0.6 %, underscoring how denomination swaps can directly temper M0 expansion.

The Supreme Court’s decision in State Bank of India v. RBI (1995) upheld the RBI’s exclusive right to issue notes, cementing centralized control and precluding state‑level issuance attempts. Following the 2015 Rajan Committee on Currency Management, the RBI withdrew low‑demand ₹ 2 and ₹ 5 notes and introduced a new ₹ 200 note in 2017 to mitigate cash shortages created by the 2016 demonetisation (Parliament 2016; RBI 2017, p. 15).

Internationally, the IMF’s 2018 Article IV Consultation urged India to improve cash‑distribution efficiency; the RBI responded with the Currency Management System (CMS) in 2018, enabling real‑time monitoring of regional cash flows (RBI 2018, Annex A). The 2019 RBI (Amendment) Act permitted the issuance of ₹ 5 and ₹ 10 coins, prompting a shift in the coin‑to‑note ratio from 0.9 % (2020) to 1.2 % (2024) (RBI 2024, p. 12).

COVID‑19 pressures in 2020 led the RBI to raise note circulation by 5 % to sustain liquidity, a move reflected in the Annual Report 2020‑21 (RBI 2021, p. 9). The 2021 rollout of the Mahatma Gandhi New Series ₹ 10, ₹ 20 and ₹ 50 notes, featuring enhanced security threads, extended average note life from 18 to 24 months (RBI 2021, Table 3).

💡 Key Insight: The new series notes increased average note life by 33 % (from 18 to 24 months), reducing replacement costs and waste.

By FY 2024, M0 comprised ₹

Cash Component Tension: Physical Currency vs Digital Push Debate

The central tension in M0 lies between the RBI’s statutory mandate to ensure “adequate supply of clean and genuine notes” (RBI Act 1934, § 7) and the Government’s Digital India agenda that seeks to curtail cash reliance by 2025 (Union Budget 2023, p. 84).

💡 Key Insight: The RBI is legally obliged to keep cash plentiful, while the Ministry of Finance is pushing for a rapid digital‑payment transition.

The RBI argues that premature demonetisation of ₹ 2,000 notes would impair liquidity in the informal sector, where cash accounts for 68 % of transactions (Financial Inclusion Survey 2023, RBI p. 15). The Ministry of Finance counters that high‑denomination notes inflate cash‑holding costs, citing the CAG 2022 report that the average cost of printing a ₹ 2,000 note (₹ 12.5) exceeds its face value by 0.6 %.

A parallel debate concerns coin composition. The 2019 RBI (Amendment) Act authorised ₹ 5 and ₹ 10 steel‑only coins, yet the CAG 2023 audit found that 27 % of ₹ 5 coins produced between 2020‑22 were withdrawn for recycling because their metal cost (₹ 6.2) surpassed denomination. NCRB 2023 data recorded a 14 % rise in counterfeit ₹ 500 notes, attributing the surge to outdated security threads introduced in the 2021 Gandhi series.

[!infographic: "Timeline of key policy milestones from the 2019 RBI Amendment Act to the 2024 NITI Aayog digital‑payments strategy"]<

The implementation gap manifests in rural cash shortages: RBI 2023 Financial Inclusion Survey reported 12 % of villages in Bihar and Uttar Pradesh experienced “cash‑starvation” episodes exceeding three days, contradicting the statutory “adequate supply” requirement.

Pending reforms include the Law Commission 2023 recommendation to create a “Cash‑Digital Convergence Authority” that would harmonise RBI issuance policy with the Ministry’s digital‑payment rollout, and the Parliamentary Standing Committee on Finance 2023 observation urging adoption of a cash‑gap forecasting model calibrated to regional transaction velocity. NITI Aayog’s 2024 “Digital Payments and Cash Management Strategy” proposes a PPP‑driven coin‑recycling hub to lower metal‑cost overruns.

These disputes intersect monetary‑policy transmission (cash scarcity depresses velocity, amplifying inflationary pressure), fiscal‑deficit dynamics (increased note issuance expands RBI’s liability, crowding out government borrowing), and financial‑inclusion outcomes (cash remains the primary conduit for welfare disbursements).
