Seigniorage (from the Old French seigneur, "lord") originally referred to the fee a feudal lord charged for minting coins from a subject's bullion. In modern usage it describes the revenue an issuing authority captures when the face value of the money it creates exceeds the resource cost of producing and distributing it.
There are two main forms economists distinguish:
- Monetary seigniorage: the real resources a government acquires by printing new base money. If a central bank issues a $100 bill costing roughly $0.17 to produce (a figure regularly cited by the U.S. Federal Reserve for its highest-denomination notes), the gap is captured by the state.
- Fiscal or opportunity-cost seigniorage: the interest the central bank earns on the assets it holds against non-interest-bearing liabilities (cash in circulation). The Federal Reserve, for example, remits its net earnings to the U.S. Treasury each year; the European Central Bank distributes monetary income to national central banks of the Eurosystem under Article 32 of the ESCB Statute.
Seigniorage matters in international relations for several reasons. The "exorbitant privilege" — a phrase attributed to French finance minister Valéry Giscard d'Estaing in the 1960s — refers to the seigniorage and financing advantages the United States derives from the dollar's role as the dominant reserve currency, since foreigners hold large quantities of non-interest-bearing or low-yielding dollar claims.
For developing economies, heavy reliance on money creation to finance deficits — sometimes called the "inflation tax" — has historically produced hyperinflation, as in Weimar Germany (1923), Zimbabwe (2007–2009), and Venezuela (2016 onward). Dollarized economies such as Ecuador (since 2000) and El Salvador (since 2001) explicitly forgo seigniorage in exchange for monetary credibility.
Seigniorage is also central to debates over central bank digital currencies (CBDCs), stablecoins, and cryptocurrencies, which redistribute or contest the traditional monopoly of states over money issuance.
Example
In 2023 the U.S. Federal Reserve remitted billions less to the Treasury than in prior years because rising interest paid on bank reserves cut into its seigniorage income.
Frequently asked questions
They are related but distinct. Seigniorage is the revenue from issuing money; the inflation tax is the erosion of the real value of existing money balances when issuance causes inflation. Heavy seigniorage financing typically produces an inflation tax.
