No, Ambedkar did not propose a Bitcoin-like currency

It began as a passing remark in a discussion on X Spaces, barely two minutes long, and many have latched on to it since. The claim is that Dr B. R. Ambedkar, in The Problem of the Rupee: Its Origin and Its Solution (1923), proposed a currency of fixed supply, and that this was the original Bitcoin-like proposal, made more than 80 years before Satoshi Nakamoto. Nothing more detailed has been offered; fixed supply is the whole of the case. It is an attractive story. An economist trained at Columbia and the London School of Economics anticipates the central idea of the best-known monetary experiment of our time.

The story has a real textual anchor, and it should be stated fairly. In his preface Ambedkar notes that most critics of the Indian system wanted to stabilise the rupee by making it convertible into gold. He thought a far better way would be “an inconvertible rupee with a fixed limit of issue” (Ambedkar 1923, p. vi). The last sentence of the book repeats the formula in capital letters (p. 303). A reader who stops there may be forgiven for hearing an echo of 21 million coins.

The trouble begins when one keeps reading. The limit Ambedkar wanted applied to one coin, the silver rupee, inside a system whose gold and paper money could both expand. Why he wanted it, who was to enforce it, and what was to circulate beside it bear only a limited resemblance to Bitcoin. And the principle he relied on was not his invention. Ambedkar says so himself.

What Ambedkar actually proposed

The Problem of the Rupee is a history and critique of Indian currency policy from 1800 to the early 1920s, written under the supervision of Professor Edwin Cannan of the London School of Economics. Its target is the gold exchange standard. Under that system the silver rupee was a token: a coin whose face value was held above the worth of its metal. The background was the fall of silver. From 1873 the gold price of silver declined and the rupee’s sterling exchange fell with it, from an average of about 22d. in 1874–75 to under 17d. in 1891–92. That raised the cost of the Government’s gold payments and deranged its budgets (pp. 91–94, 114). In June 1893, to arrest the fall, the Indian mints were closed to the public’s free coinage of silver (pp. 146–147). The Government, however, kept the power to coin rupees on its own account (pp. 148–149), and the Fowler Committee later endorsed its doing so according to the requirements of the public (p. vii).

Ambedkar’s complaint is that this left the quantity of money to official discretion, and gave the issuer a financial interest in using it. Because a rupee passed for more than its silver cost, each rupee coined brought the Government a profit, which economists call seigniorage. He argues that prices in India rose after the closure, and rose more than gold prices did (pp. 251–252), and that a gold reserve built out of those profits could grow only when more rupees were coined (pp. 235–238). The profits were a standing temptation. In 1907, he notes, they were spent on extending the railways (p. 303).

His remedy is stated most compactly in the plan he put before the Royal Commission on Indian Currency and Finance on 15 December 1925 (Ambedkar 1925, Q. 6097). It had four parts:

1. Stop the coinage of rupees by closing the mints to the Government, as they already were to the public.

2. Open a gold mint to strike a suitable gold coin.

3. Fix a ratio between the gold coin and the rupee.

4. Make neither convertible into the other, and let both circulate as unlimited legal tender at the ratio fixed by law.

The fourth point can look contradictory. Inconvertible here means only that the Government would be under no obligation to exchange rupees for gold on demand. The legal ratio was to be held by keeping rupees scarce, not by a promise to redeem them, which is how he understood the French and American silver coins to have kept their value (1923, pp. 285–286, 290–294).

Two features of this plan decide the present question.

Only the silver rupee coin was to be fixed. Gold was to be coined at an open mint and to flow in and out of the country freely (1923, p. 294; 1925, Q. 6075, 6097). Paper notes were to continue. He told the Commission that the rupee would be fixed in limit while notes stayed fully convertible, and that the fiduciary issue could be extended against commercial paper to meet seasonal demand (Q. 6108, 6253–6254). The note issue was given no fixed numerical ceiling. It was left to the Government’s discretion, with convertibility as the restraint on the issuer (Q. 6116, 6255). When the chairman raised the danger of contraction, Ambedkar answered that a fall in prices could be guarded against by increasing the paper currency (Q. 6084). This is a gold standard with an elastic, convertible note issue and a frozen stock of token coin. It is not a fixed money supply.

The aim was stable prices, and the quantity served that aim. The preface insists that nothing will stabilise the rupee unless its general purchasing power is stabilised (p. vi). The final chapter promises that with rupee coinage stopped, prices would be steadier and the exchange secure (p. 297). Before the Commission he said the unit should be stable in terms of commodities (Q. 6071–6072). He did not claim perfection for gold; perfect stability of value, he concedes, is only an ideal (p. 255). The size of the rupee stock followed from that aim. How many rupees should be melted, he says, depends on the gold value the rupee is meant to have; the stock should be kept below the minimum the public will always demand, so that scarcity holds it at par (1923, pp. 293–294). In 1925 he agreed that part of the gold standard reserve could be used to call in rupees and not reissue them (Q. 6099–6100).

The preface also floats a bolder variant: melt the rupees, sell the silver, and fill the gap with inconvertible paper. Ambedkar calls it sound but does not press it (pp. vi–vii). Even there the paper would sit beside gold as legal tender, and he adds that the resulting arrangement would conform to the principles of the English currency system (p. vii). The Commission did not take up his plan. Its 1926 report recommended a gold bullion standard under which gold was not to circulate as money, together with a new central bank, the future Reserve Bank of India (Federal Reserve Bulletin, September 1926, pp. 657–664; Reserve Bank of India, chronology).

Four places where the comparison breaks down

The current claim of “Bitcoin-like” has to mean something, and Bitcoin is defined by its founding documents. The 2008 paper is titled Bitcoin: A Peer-to-Peer Electronic Cash System. The problem it sets out to solve is double-spending: how to stop a digital coin being spent twice without a trusted third party to check. Its answer is a peer-to-peer network that timestamps transactions by proof-of-work (Nakamoto 2008). Its eight references are to cryptography, computer science, and probability theory. No economist is cited.

The white paper does not specify the 21-million limit or set a price-stability target. It does discuss coin issuance, which it compares to gold mining, and an eventual shift to funding by transaction fees once a predetermined number of coins has entered circulation (Nakamoto 2008, §6). The limit itself came with the software. Announcing the first release on 8 January 2009, Nakamoto wrote that total circulation would be 21,000,000 coins, created as rewards for the nodes that produce blocks (Nakamoto 2009a). The reward halves every 210,000 blocks, roughly every four years (Bitcoin v0.1.5 source). A month later he named the root problem with conventional money as the trust it demands: in central banks not to debase it, and in banks to hold and move it (Nakamoto 2009b).

The claim rests on fixed supply alone, so that test comes first. The other three show how little else the two schemes have in common.

What is capped. Bitcoin caps its native unit, which is the base money of its own system. Ambedkar caps a subsidiary token coin and leaves his base money, gold, uncapped, together with a convertible note issue that has no fixed numerical ceiling. The thing he fixes is not the base of his system, and limiting one component of a currency is not the same as limiting the supply of money.

What it is anchored to, and what it is for. Ambedkar’s rupee is defined by a legal ratio to gold. Scarcity is his instrument for holding that parity and, through it, for steadier prices, so the quantity of rupees follows from a price target. Bitcoin has no fixed gold or fiat redemption parity, and its design documents set no price objective. Its quantity is given and its price is left to the market.

Who enforces the limit. Ambedkar’s limit is a legal prohibition laid on a state mint and backed by legal-tender law. He cites with approval a Government despatch of 27 April 1859 which held that restriction of issue must be imposed by law, and by Parliament (1923, p. 299). His money remains the state’s money, struck at the state’s mint and circulating at the state’s ratio. Bitcoin exists in order to have no central issuer and no trusted third party. Ambedkar wanted to bind the sovereign. Nakamoto wanted to do without one.

How scarcity is produced. Ambedkar would stop new coinage at once and, if need be, shrink the existing stock. Bitcoin replaces discretionary central issuance with issuance governed by its protocol, through rewards to the miners who produce valid blocks.

If a state-issued, legal-tender silver coin whose further minting is forbidden, circulating beside freely coined gold, is “Bitcoin-like”, then so was the French five-franc piece of the 1880s. Which brings us to the question of priority.

Not the first, by his own account

The claim of priority fails on the testimony of the book itself. Cannan, who supervised the work, wrote its foreword. He summarises the plan just as above: no further enlargement of the rupee issue, the mints open to gold, and in time a currency of gold coins beside a fixed stock of rupees. He then observes that it follows European precedents. Keeping a mass of full legal-tender silver in circulation beside gold after the mints had been closed to silver involved no new principle, he writes, because France, Germany, and the United States had already done it (Cannan 1923, p. xii).

Ambedkar agrees. In his final chapter he points to the French five-franc piece and the American silver dollar: unlimited legal tender, not convertible into gold by law, and needing no convertibility because their quantity was strictly limited (pp. 285–286, 290–291). He describes the Indian system of the 1890s as approximating to the Bank Charter Act of 1844, with the rupee issue limited and gold unlimited (p. 279). And he presents his plan as a return to what the Government of India had itself proposed in its despatch of 3 March 1898, which contemplated melting rupees to contract the currency (pp. 292–294). No reader of the book can come away thinking the idea began with its author.

The lineage is long and well documented, in theory and in practice.

• 1821, Ricardo. In the chapter on currency and banks in the third edition of his Principles (first published in 1817), David Ricardo argued that paper money need not be payable in coin to keep its value. “By limiting its quantity”, it would exchange at the value of the coin it replaced. His concern was to regulate the quantity by reference to a metallic standard, not to freeze it for ever, and he recommended convertibility as the practical check on issuers (Ricardo 1821, ch. 27).

• 1844, the Bank Charter Act. The Act initially limited the Bank of England’s securities-backed note issue (the fiduciary issue) to £14 million, with provision for specified increases as other banks gave up their rights of issue. Any further notes required metallic backing (7 & 8 Vict. c. 32, s. II; s. V). It was a statutory restriction on the discretionary part of a currency, enacted 79 years before Ambedkar’s book, though not an immutable numerical cap.

• 1870s, the limping standard. The members of the Latin Monetary Union suspended the free coinage of silver one after another between 1873 and 1878. France began limiting it in 1874 and stopped coining five-franc pieces in 1876. The existing silver coins stayed in circulation as full legal tender. Irving Fisher’s 1911 treatise explains that such coins stay at par primarily because their quantity is limited, helped by their legal-tender status, by public confidence and, in the American case, by the Treasury’s duty to maintain parity. He adds that irredeemable paper can hold its value in the same way, and uses India’s closure of the mints in 1893 as a worked example (Fisher 1911, ch. VII).

• 1878, the greenback freeze. The United States Congress forbade any further retirement of legal-tender notes (Act of 31 May 1878). The measure came out of a political fight over contracting the currency, not out of a theory of fixed supply, but its effect was to fix the outstanding stock of this government paper money at a little over $346 million (Bureau of Engraving and Printing 2013).

• 1876 to 1898, India. A Bengal Chamber of Commerce resolution of 1876 and a plan associated with Colonel Smith proposed ending the free coinage of silver. The Government first saw fatal objections, then revived the idea in its despatch of 21 June 1892. The Herschell Committee approved, and the Act of 26 June 1893 carried it out (1923, pp. 145–147). In 1898 the Government went further and proposed melting rupees to contract the currency (pp. 292–293). Cannan records in the foreword that he was one of the few economists who believed, in 1893, that the method would hold the rupee at a fixed ratio to gold (p. xi).

Nor did the idea rest there. In 1984 Milton Friedman proposed freezing American high-powered money (the monetary base) outright, issuing new notes only to replace worn ones, in order to remove discretion from monetary policy altogether. The freeze applied to the base alone; he expected broader money, including deposits, to go on growing at about 3 percent a year (Friedman 1984, pp. 634–635). Even so, a frozen base goes further towards a fixed supply than Ambedkar ever did.

Against this background Ambedkar’s real contribution comes into focus. He did not discover that limitation of quantity maintains the value of money. He argued, against Keynes and the official consensus, that the closure of 1893 had been left half done because the Government exempted itself, and that the exemption had to end. That is a pointed and original argument about Indian policy. It is not the invention of fixed-supply money.

What the two do share

There is a real, if limited, analogy between what Ambedkar proposed and Bitcoin today. Both schemes seek to constrain discretionary issuance. Ambedkar distrusted the issuer: his final chapter argues that the profits of coinage tempt a government to over-issue, and it quotes Cannan on the danger of entrusting unlimited money creation to governments (pp. 297, 303). Cannan’s foreword commends the plain gold standard because administrators and legislators find it far harder to tamper with than the gold exchange standard (pp. xi–xii). Nakamoto’s complaint about central banks debasing the currency is recognisably the same sentiment.

But that sentiment is the common property of a hard-money tradition running from Ricardo, who held that neither a state nor a bank could be trusted with an unrestricted power of issue, to Friedman. If sharing it makes one a forerunner of Bitcoin, the queue is two centuries long and Ambedkar stands well back in it. His remedy, moreover, runs the opposite way. He wanted a better law to govern the state’s money. Bitcoin was designed to work with no central authority at all.

It would also be a mistake to tidy him into a modern camp. Asked in 1925, he said he was “rather in favour of falling prices” than rising ones (Q. 6089), a line that a Bitcoin enthusiast might seize on. Yet in the same sitting he said that a fall in prices could be countered by expanding the note issue (Q. 6084), and he wanted room for seasonal expansion (Q. 6108, 6254). These are the positions of a gold-standard economist of the 1920s arguing over the rupee’s ratio. They are no prophecy of digital scarcity.

The cost of the claim

The claim shatters when examined with historical reference. A currency of fixed supply? Only the token rupee was to be fixed. Gold and convertible paper notes could expand; the note issue had no fixed numerical ceiling, though convertibility constrained the issuer. Bitcoin-like? Only in a limited sense: both schemes seek to constrain discretionary issuance. That resemblance does not establish equivalence, anticipation, or influence, and the two go about it by opposite means, Ambedkar through a law binding the state’s mint and Bitcoin operates through a protocol with no central issuer. Was Ambedkar the first to suggest it? Not by his own account, nor by his teacher’s, nor by the record of the century before him.

The higher cost is to Ambedkar’s intellectual legacy. The Problem of the Rupee reconstructs a century of Indian currency policy from despatches and committee reports, takes on Keynes by name, and argues that the purchasing power of the rupee is the true test of the system. One may dispute its conclusions; Cannan did, in the foreword to the book itself (p. xi). What one should not do is honour the remarkable work by crediting its author with an invention he never claimed, in a field that did not yet exist.

Ambedkar, the economist, is best honoured by being read, not by making false and misleading claims about him.
