A short film in the language of this site's homepage: prices as signals, in Hayek's phrase; the Austrian argument that money losing value blurs them; the Austrian account of booms and busts, as Mises and Hayek told it, and Milton Friedman's objection; what a 2 per cent target does to savings over time; and bitcoin's supply, set by rule: measured in fiat its price moves, but one bitcoin is always one bitcoin.

Module 4 of 4The Austrian critique. What does money that keeps changing do to prices, to plans and to saving? The Austrian School of economics has its own answer.
1945Prices carry information. When something grows scarce its price rises, and people who will never know why still use less of it. Friedrich Hayek called the price system “a mechanism for communicating information”.F. A. Hayek, “The Use of Knowledge in Society”, American Economic Review 35(4), 519–530 (September 1945)
The argumentAustrian economists argue that money itself has to be a steady measure for prices to work. When it loses value at an uncertain rate, a rising price might mean real scarcity, or just more money, and no one can easily tell which. The signal blurs, and plans made on it go wrong.
Mises, 1912Interest is a price too: the price of time, of having something now rather than later. In The Theory of Money and Credit (1912) Ludwig von Mises set out the beginnings of a theory of the business cycle, which Hayek developed: when banks lend more than people have saved, and interest is held below the level real savings would set, the low rate is a false signal.Ludwig von Mises, The Theory of Money and Credit (Theorie des Geldes und der Umlaufsmittel, 1912)
The boomCheap credit looks like plenty of savings. So businesses start long projects, such as factories, towers and new lines of production, more of them than real savings can finish.
The bustWhen rates rise, the projects that only paid at the low rate stop. The Austrians call them malinvestments, and the stopping is the bust. Awarding Hayek a share of the 1974 economics prize, the Nobel committee summed up his argument: monetary expansion, with lending beyond what people had voluntarily saved, could misallocate resources, above all capital.The Sveriges Riksbank Prize in Economic Sciences 1974, press release (9 October 1974)
1993Many economists dispute the Austrian account, and see other causes for booms and busts. Milton Friedman found that the size of a fall predicted the size of the recovery after it, but the size of a boom did not predict the bust that followed. That, he wrote, would cast doubt on theories that blame a deep depression on the excesses of the boom before it, naming Mises’s as an example.Milton Friedman, “The ‘Plucking Model’ of Business Fluctuations Revisited”, Economic Inquiry 31(2), 171–177 (1993)
1996The Austrian economist Roger Garrison replied that figures for total output alone cannot rule out a boom-and-bust theory. The argument continues.Roger W. Garrison, “Friedman’s ‘Plucking Model’: Comment”, Economic Inquiry 34(4) (October 1996)
Time preferenceAustrians also argue that money which keeps losing value rewards spending and borrowing over saving, and shortens the horizon of every plan. Central banks aim for a little inflation on purpose: at the 2% that the Federal Reserve, the Bank of England and the European Central Bank all target, money loses half its value in about 35 years.Federal Reserve, Statement on Longer-Run Goals (2% target); half-life ln 2 ÷ ln 1.02
BitcoinBitcoin’s supply is set by a rule that every node checks, not by a committee: never more than 21,000,000 coins. New coins go only to the miners who add each block, as payment for that work, “since there is no central authority to issue them”, as its design paper put it in 2008. Austrians call money whose supply cannot be expanded at will sound money.Satoshi Nakamoto, Bitcoin: A Peer-to-Peer Electronic Cash System (2008), section 6, Incentive
One bitcoinThe supply is fixed. Measured in fiat, bitcoin’s price moves, but one bitcoin is always one bitcoin: you don’t price bitcoin, you price things in it. Few prices are set in it yet, and keeping it safe takes care.
The Bitcoin TransitionMoney by rule, not by committee.

The Austrian School's critique of fiat money is not a political complaint. It is a technical argument about economic calculation — the ability of market participants to use prices to plan and coordinate production across time. The argument, made most clearly by Mises in 1912, is that debasement of the monetary unit makes economic calculation systematically less reliable, and that the consequences propagate through every level of the economy.

What Economic Calculation Requires

Markets coordinate production through prices. When an entrepreneur considers a new factory, a new product, or a new hire, she looks at the price of inputs, the price of competing goods, and the price of capital. These prices convey information about relative scarcity — what the market values and how intensely.

For this signalling to work, the unit in which prices are expressed must itself be stable. If the currency is losing value at an unknown rate, then changes in the nominal price level reflect a mixture of real shifts in relative scarcity and artificial shifts from monetary expansion. The entrepreneur cannot distinguish the two. Her calculations become systematically noisier, and her decisions worse.

Malinvestment and the Business Cycle

When central banks suppress interest rates below the level that would clear the market for real savings, borrowers receive a false signal that more savings are available than actually are. They begin long-term projects — factories, skyscrapers, infrastructure — that require patient capital to complete. But the patient capital does not exist. It is an accounting illusion created by credit expansion.

Eventually, the expansion slows or reverses. Interest rates normalise. The projects that were viable only at suppressed rates become unprofitable. They liquidate. This is the bust. The Austrians call the wasted projects "malinvestments" — investments that would not have been made under a sound money regime.

Every major recession since the founding of the Federal Reserve in 1913 fits this pattern. Boom, expansion, malinvestment, correction. The Great Depression, the 1970s stagflation, the dotcom crash, 2008, 2020–2022. Each preceded by aggressive monetary expansion, each followed by an attempt to paper over the correction with more expansion.

The Time Preference Argument

The final part of the Austrian critique concerns how debasement changes individual behaviour. When money loses value over time, rational actors lower their time horizons. Saving becomes irrational. Speculation becomes rational. Debt becomes rational. Long-term commitments become harder to justify.

This is not a moral claim. It is a response to incentives. Under a monetary regime that punishes saving, people save less. Under a monetary regime that rewards speculation, people speculate more. The civilisational consequences — slower family formation, shorter business cycles, more fragile capital structures — follow mechanically.

What is needed first and foremost is to renounce all inflationist fallacies. This renunciation cannot last, however, if it is not firmly grounded on a full and complete divorce of ideology from all imperialist, militarist, protectionist, statist, and socialist ideas. — Ludwig von Mises, 1923

The Bitcoin Response

Bitcoin does not refute the Austrians. It implements them. Sound money, by their definition, is money whose supply cannot be expanded at will. Bitcoin's supply cannot be expanded at will. The Austrian framework predicted the failures of fiat. It also predicted what a successful alternative would need to look like. Bitcoin satisfies those requirements.
