Seigniorage

Definition

Seigniorage is the profit that accrues to whoever issues a currency — classically, the difference between a coin's face value and its cost of production, a prerogative of monarchs and, later, states.[1] In a modern economy the concept extends to all new base money a central bank issues (cash, and central-bank reserves), for which "the cost to the state of issuing new money is only the cost of producing banknotes and coins" while the state receives the money's full face value as public revenue.[1] The reform literature covered on this page extends the term further still, to the value created when commercial banks originate new deposit money as a byproduct of lending — the mechanism described on this wiki's bank money creation page — arguing that this, too, is a form of seigniorage, currently captured privately rather than publicly.

The Reform Case: Huber & Robertson

The fullest statement of this argument is Joseph Huber and James Robertson's Creating New Money: A Monetary Reform for the Information Age (New Economics Foundation, 2000), commissioned by NEF and prefaced by Frances Cairncross. Its starting fact: "ninety-seven pounds in every one hundred circulating in the [UK] economy" is issued by commercial banks as interest-bearing deposits, not by the state as cash, and "the cost to the banks of issuing new money is virtually zero" — so "the benefits of the money system are... being captured by the financial services industry rather than shared democratically."[2]

Huber and Robertson call their reform proposal — abolishing commercial banks' capacity to create new money via lending, and vesting money creation solely in central banks acting as an arm of public finance — "seigniorage reform."[2] Under it, central banks would issue new money "as debt-free payments — outright grants" into government accounts, which governments would then spend into circulation like any other public revenue.[2] They estimate the annual scale of what is currently forgone: seigniorage revenue foregone to the UK public purse "of the order of £47bn a year," a corresponding "hidden subsidy" to commercial banks in special profits "of the order of £21bn a year," and comparable figures for the US (~$37bn in special bank profits), the Eurozone (~€58bn), and Japan (~¥1,846bn) — figures the authors put at 5–15% of annual tax revenues across the major OECD economies.[2] The mechanism they describe: a bank funding a loan with money it created costs itself nothing in interest, so its margin is "not... 5% normal profit" but "5% normal profit plus [a] 4% additional special profit" hidden from customers because "most people do not know how the system works."[2]

The Explicit Georgist Parallel

The report draws the Georgist connection itself, not as an outside inference. Its argument rests on "the principle that the value of common resources should be shared among all citizens; it should not be 'enclosed' by private interests" — a principle the authors say "also supports... the 'tax shift'... away from taxes on employment, incomes, profits and value added, and towards higher taxes or charges on energy, resources, pollution and the site-value of land."[2] Discussing the ethics of the special bank profit, the authors directly cite land economist Mason Gaffney: "In a talk in London in 1999 on land value taxation Professor Mason Gaffney... referred to the reaction of some right-wing... economists to calls for economic justice[:] 'TANSTAAFL'... As he pointed out, they are wrong. The truth is TISATAAFL (there is such a thing as a free lunch); and the important questions are WIGI (who is getting it?) and WOTGI (who ought to get it?)."[2] Applied to money issuance: "the commercial banks are now getting the free lunch; in future all citizens ought to get their share of it — as public revenue."[2] The report even floats spending the recovered seigniorage as "a national dividend or citizen's income... reflect[ing] the entitlement of every citizen to share in the monetary value of common resources" — the same commons-dividend logic behind this wiki's citizen's dividend concept, applied to money rather than land.[2]

The Organizational Heir: Positive Money

Positive Money, the UK monetary-reform campaign founded by Ben Dyson in 2010, campaigns for essentially the Huber–Robertson "sovereign money" proposal — transferring the power to create money from commercial banks to a public authority — and its broader corpus (cited elsewhere on this wiki for its bank-lending-composition research) shares Huber and Robertson's premise that commercial money creation is a publicly valuable prerogative currently captured privately.

Why It Matters to the Rent Debate — and Its Honest Limits

This is the finance-rents domain's most direct structural analogue to land rent: a scarce, sovereign-conferred privilege (money issuance) whose value, reformers argue, should be a captured public asset rather than a private windfall — the same logic this wiki applies to land, spectrum, and natural-resource rents. But the analogy should be held to the same rent-gradient honesty as any frontier claim, and it is considerably more contested than the land case:

• The "hidden subsidy" framing is advocacy, not settled economics. Creating New Money is a policy report from a reform-advocacy commission, not a peer-reviewed paper; its "special profit" estimates are the authors' own calculation (Appendix Table 4), not independently replicated, and the report itself is now a quarter-century old.
• Mainstream monetary economics offers a competing account of the same margin. Central-bank explainers of money creation (e.g., the Bank of England's McLeay, Radia & Thomas 2014, cited on bank money creation) describe banks as balance-sheet-constrained by capital and liquidity regulation, competition, and default risk — meaning the interest margin on newly created deposits compensates for risk-bearing and regulatory cost, not pure windfall. This is structurally the same dispute Cochrane raises against reading finance's income as rent: whether a margin reflects a competed-away service cost or an uncompeted rent is precisely the question mainstream and heterodox monetary economists disagree on here too.
• Full-reserve/"sovereign money" proposals have a mixed reception even among sympathetic economists. IMF researchers Jaromir Beneš and Michael Kumhof revisited a similar 100%-reserve proposal (the 1930s "Chicago Plan") in a 2012 IMF working paper and found simulated macroeconomic benefits (debt reduction, business-cycle smoothing) — but as a monetary-architecture simulation, not a validated real-world result, and the proposal remains outside the mainstream policy consensus.[3] (Kumhof separately co-authored the wiki's land-tax stimulus paper with Goodhart, Hudson and Tideman — a distinct proposal, about land taxation rather than money issuance, that should not be conflated with this one.)
• No wiki-grade empirical estimate exists for other jurisdictions or years. The £47bn/$37bn/€58bn/¥1,846bn figures are UK/US/Eurozone/Japan, circa 1999–2000, and have not been updated or cross-checked by this wiki against current monetary aggregates.
