Ludwig von Mises and Monetary Theory¶

Ludwig von Mises (1881–1973) was an Austrian-born economist and, alongside Carl Menger and Friedrich Hayek, one of the central figures of the Austrian School. His 1912 book The Theory of Money and Credit is the school's foundational text on monetary economics specifically, and it is the source of the regression theorem, a piece of monetary theory that comes up constantly, and is frequently misapplied, in debates about whether Bitcoin can function as money. This chapter covers Mises's actual arguments, separate from later Bitcoin-era reinterpretations, which are addressed directly in Austrian Economics and Bitcoin.

Building on Menger¶

Mises accepted Carl Menger's account of money emerging from the market's spontaneous ranking of goods by saleableness, and set out to extend it: if money's value today depends on people expecting to exchange it for goods tomorrow, and that expectation depends on today's exchange value, where does the chain of expectations originate? Money can't simply be valuable "because it's money", that would be circular reasoning, explaining money's value by assuming money's value.

The regression theorem¶

Mises's answer is that the value of money today must be explained by tracing it backward through time: people value money today partly because of what money could buy yesterday, whose value was in turn explained by what it could buy the day before that, and so on. This chain cannot regress infinitely. Mises argued it must terminate at a specific historical point: the moment a good was valued purely for its non-monetary use (as a commodity with direct utility, for gold, its use in ornamentation and, in some contexts, tools) before it began being used as a medium of exchange at all.

"Before an economic good begins to function as money it must already possess exchange value based on some other cause than its monetary function. But money that already functions as such may remain valuable even when the original source of its exchange value has ceased to exist." Ludwig von Mises, The Theory of Money and Credit, 1912

This is why Mises argued that a good cannot become money "in one step" simply by declaration. Its acceptance as money has to build historically on a prior, non-monetary exchange value that gave people an initial reason to want it, before the self-reinforcing saleableness dynamic Menger described could take hold. Once a good is established as money, Mises noted, its exchange value can persist even after the original non-monetary use becomes irrelevant to most holders (as has arguably happened with gold, whose monetary and store-of-value demand today vastly exceeds its industrial and ornamental demand), but the initial bootstrapping required that non-monetary starting point.

Why this theorem became central to Bitcoin debates¶

Because Bitcoin has no significant non-monetary use (a bitcoin cannot be used as jewelry, an industrial input, or consumed in any way independent of its function as a transferable, scarce digital asset) critics have argued, citing the regression theorem directly, that Bitcoin cannot, by Mises's own logic, acquire monetary value: there is no non-monetary "anchor" good in Bitcoin's history for the value chain to regress back to. This argument was made prominently, for example, in a widely discussed 2011 article by economist Robert Murphy weighing Bitcoin against the regression theorem, and has been a recurring point of internal debate within Austrian-influenced Bitcoin commentary ever since.

Defenders of Bitcoin's compatibility with the regression theorem have offered several counterarguments, covered in more depth in The Regression Theorem and Austrian Economics and Bitcoin: some argue Bitcoin's early "non-monetary" value came from its use as a novel technological curiosity and a speculative bet on the network's future usefulness, functionally serving the same bootstrapping role Mises describes even without physical utility; others argue the regression theorem, developed to explain money's emergence from a pre-existing barter economy, does not straightforwardly apply to a good introduced into an economy that already has an established money (fiat currency) against which the new good can be directly priced and exchanged from day one. This book presents both sides as a live, unresolved dispute rather than declaring a winner. Precisely because it is a dispute about how to correctly apply Mises's own framework, not a dispute about what Mises himself wrote.

Other contributions relevant to this book¶

Mises's broader body of monetary work, beyond the regression theorem, includes arguments this book covers in other chapters:

Austrian business cycle theory, developed with Hayek, arguing that credit expansion by banks and central banks below the market's "natural" interest rate distorts investment decisions and produces unsustainable booms followed by necessary corrections. See Central Banking and Monetary Policy.
The economic calculation problem, argued most fully in Mises's 1920 essay "Economic Calculation in the Socialist Commonwealth," contending that rational economic planning requires market prices (themselves dependent on money and exchange) to compare the relative value of different uses of resources, which a centrally planned economy without genuine market pricing cannot replicate. This argument is about central economic planning broadly, not specifically about monetary systems, but is frequently cited alongside Mises's monetary work as part of the same intellectual project: understanding what decentralized, price-based coordination accomplishes that centralized control cannot.

Common misconceptions¶

Mises never wrote about Bitcoin, digital currency, or computer networks. He died in 1973, over three decades before Bitcoin's whitepaper. Every application of his regression theorem to Bitcoin is a later interpretation by subsequent writers, and this book treats it as such throughout.

The regression theorem is not a claim that money must always remain tied to a commodity forever. Mises explicitly allowed that money could become fully detached from its original non-monetary source of value over time (as he argued had already happened, to a degree, with some historical currencies), the theorem concerns money's origin, not a requirement for its perpetual backing.
