Thesis: Helmut Creutz is right that the monetary system is a source of instability. He is wrong about where the instability comes from. Interest is the market’s price of time, and treating it as a toll levied by those who hold money mistakes a thermometer for the fever. Here’s a rebuttal of the Geldsyndrom Thesis.
What Creutz Claims
Creutz’s argument is coherent. Money, unlike goods, does not spoil, so its holder can wait while everyone else must sell. That asymmetry, he says, lets holders withhold money from circulation until they are paid a premium to release it. The premium is interest. Because interest compounds, claims on the economy grow exponentially and widen the gap between creditors and debtors. To keep the circuit running, the economy must grow without limit. The cure is a carrying cost on idle money, in the tradition of Silvio Gesell, so that hoarding stops paying and interest rates can fall toward zero.
Each step follows from the one before, which is why the book deserves a serious answer instead of a dismissal. The weak point is the first step: treating interest as a payment for releasing money.
Interest Is Not a Toll
Austrian economists, from Böhm-Bawerk through Mises and Rothbard, trace interest to time preference: people prefer a good available now to the same good available later. The Mises Institute’s account states that the social rate of time preference is what determines the pure rate of interest. Interest, on this view, exists wherever people act, whether or not money does. 
The classic thought experiment makes this concrete. Robinson Crusoe catches two fish a day by hand. To build a net, he must go without fish for a few days and live off his savings. He will do that only if the net promises more fish later than he gives up now. The extra fish is interest in kind. No bank, no cash and no hoarder is involved. If Creutz were right, interest would vanish in a barter economy, but the Crusoe case shows it would not.
Money does not create the premium. It makes it visible. When a lender hands over a hundred today for a hundred and five next year, he is not extracting ransom for escaping a hoard. He is giving up the use of that purchasing power for a year, and the borrower is paying to bring forward spending that would otherwise have to wait.
Creutz borrows from Keynes the idea that interest is a “liquidity-sacrifice premium”, and that has real force: people do value liquidity. But Austrians would say liquidity preference explains why people hold cash balances, not why the pure rate of interest exists. The rate of interest on the market is a composite that includes risk and expected price changes, which is why it can be pushed around by policy. Austrians are not unanimous here. A note in the Quarterly Journal of Austrian Economics argues that two standard defenses of the pure time-preference theory are mistaken, so the foundations are still debated within the school.
Hoarding Is Not a Leak
The second pillar of Creutz’s case is that money withheld from circulation interrupts the chain of demand. In his arithmetic, a note held for a year costs the economy all the purchases it would have financed as it changed hands.
Austrians respond in three steps. First, a cash balance is itself a good that people want. Mises’s theory of the demand for money treats it as a stock people choose to hold for the security and flexibility it gives. Holding it is a use of money, not a withdrawal from use. Second, money not spent on consumption is not necessarily withheld from investment. Saved funds are lent or invested, and the real resources they release go to capital goods. Third, when people want larger cash balances, the adjustment is a change in prices. A rise in the demand for money lowers prices until the real value of existing balances satisfies it. The Austrian objection to the Gesellian model is that it treats a shift in preferences as a malfunction.
I should grant the best form of the opposing case. In a downturn, when prices and wages adjust slowly, a sudden scramble for liquidity can cause real unemployment before prices fall. Keynes made this argument. Austrians reply that such downturns usually follow credit-fueled booms that misdirected resources in the first place, and that the cure is allowing the misallocation to be liquidated. That reply is persuasive to many, but it remains contested, and the empirical record of deflationary episodes is mixed. An honest Austrian should say the stickiness problem is real and argue about how large it is, not deny it.
Compounding Is Not Destiny
Creutz’s picture of claims growing exponentially while the economy cannot keep pace is arresting, particularly when he cites German monetary assets doubling roughly every seven years. But it conflates nominal claims with real wealth. Three things interrupt the compounding.
Loans default, and borrowers go bankrupt, which erases claims. Creditors spend and consume, and fortunes are divided among heirs and dissipated across generations. Most importantly, interest is paid out of the output that borrowed capital helps produce. A rate of return on capital is a measured productivity, not a decree. If capital is productive, compounding reflects the growth it creates. If it is not, defaults and losses correct it.
Where claims do grow faster than real output for long, Austrians look to credit expansion. When a central bank holds rates below what savers would otherwise supply, the signal to entrepreneurs is false. Mises Daily puts it plainly: artificial suppression of the interest rate causes malinvestment and the subsequent bust, and pushing rates down further makes matters worse. If the debt overhang Creutz describes is real, the Austrian diagnosis is that it was inflated by the policies he wants to deepen.
The Bracteate Boom and Wörgl
Creutz’s historical evidence is that medieval bracteates, thin coins periodically recalled and re-minted at a discount, produced a boom, and that the experiment at Wörgl in 1932 and 1933 showed the same effect.
Both cases raise questions he doesn’t answer. The periodic recall of coins, the renovatio monetae, was primarily a revenue device for the issuing lord: each recall was a levy on holders. Whether it also sped up circulation is plausible, but medieval Europe’s growth had many other causes, including agricultural improvement, population growth, the spread of markets and town charters. Isolating the effect of the coin is hard, and I would treat any single-cause account with suspicion.
Wörgl is better documented but narrower. It was a small Austrian town, its stamped scrip circulated for about a year, and the Austrian National Bank had the scheme halted. A short, local experiment in a depressed economy tells us little about what a permanent carrying cost would do to a whole economy’s saving and capital formation. Spending fast to avoid a fee is expected behavior. It says nothing about whether the spending was well directed.
Where Creutz and the Austrians Agree, and Where They Don’t
It would be a mistake to treat Creutz as an enemy of the Austrian tradition. He criticizes central banks, doubts their targets and cites the Bundesbank’s loss of purchasing power. On that Austrians nod. Mises and Hayek spent careers arguing that central banks cannot manage the money supply wisely, and Hayek’s 1976 Denationalisation of Money proposed letting private issuers compete.
The disagreement is over the remedy. Creutz would put money issue in public hands, more tightly controlled, and add a levy on holdings. Austrians would take away the monopoly. The cases are not symmetrical: a state that gains the power to charge people for holding money gains a powerful tool, and nothing in the history of public money suggests that tool would be used with restraint.
There is a second, sharper disagreement. Creutz holds that commercial banks lend out existing savings and do not create money. Austrians in the Rothbard and Hülsmann tradition argue the opposite: fractional-reserve banks issue money substitutes beyond the savings available, which is exactly what drives the credit cycle. Here the two sides are talking past each other, and mainstream economists, who generally describe banks as creating deposits when they lend, side with the Austrians on the mechanism if not the policy conclusion.
The Fee Is a Negative Rate
Creutz’s proposal can be judged on its own terms. A fee on idle money is a negative interest rate on cash. It makes holding money costly, so people will spend it or move it into other stores of value.
Austrians predict three effects. Saving falls, because the return on holding wealth in monetary form is cut. Consumption and speculative purchases of real assets, such as property, gold and art, rise as people look for a way to avoid the fee. And the interest rate does not disappear: it falls below time preference, which means investment is financed not by real saving but by the very distortion the school warns against.
The recent record is suggestive, not decisive. The European Central Bank took its deposit rate below zero in 2014, and several other central banks followed. Defenders say the effects were modest and the measures helped avoid deflation. Critics point to inflated asset prices and weak bank profitability. Both claims are arguable, and the episode is a policy experiment, not a clean test of Gesell’s theory.
Conclusion
Creutz sees real things: hoarding does occur in a crisis, the monetary system is distorted, and debt has outrun income in many economies. His error is to explain these by a property of money and interest, when the more economical explanation lies in the institutions that govern money. Interest is the price of time. It rises and falls with how people value the present against the future, and attempts to override it have produced the instability he deplores.
The practical takeaway is institutional, not moral. If we want money that does not distort the structure of production, we should reduce the state’s role in issuing it, not enlarge it. What would count as evidence against the Austrian view is a case where a carrying cost raised real saving and investment over many years without distorting asset markets, and so far no such case exists.
