An Austrian Lens: ZiGDTDF and the Mirage of Forged Steadiness

By Jabulani Simplisio Chibaya

HARARE – THE Reserve Bank of Zimbabwe (RBZ) has launched the ZiG Denominated Term Deposit Facility Bill (ZiGDTDF) — a new savings instrument promising positive returns and currency stability. But what would the great thinkers of the Austrian School of Economics make of it? And what does it mean for the “mufana” selling tomatoes in Mbare, the teacher waiting for her salary in Bindura, or the small business owner in Bulawayo struggling to keep prices steady?

A Familiar Promise in New Packaging

Walk through any Harare kombi rank on a Monday morning and you will hear the same conversation that has echoed across decades of Zimbabwean life: “Ndeipi wangu munyika umu? Mari yedu icharamba yakasimba here?” — What is happening in this country? Will our money remain strong?

That anxiety is not irrational. It is the lived product of a monetary history that has destroyed savings, wiped out pensions, and forced an entire generation to think in US dollars, rand, and mobile money rather than trust any domestic currency. Now, the RBZ is asking Zimbabweans to trust again — this time through an instrument called the ZiG Denominated Term Deposit Facility Bill, or ZiGDTDF, introduced in the February 2026 Monetary Policy Statement and now operationalised through a public invitation for investors.

The facility promises that after investing ZiG for 90 days, the RBZ will return the principal plus the interest. It targets individuals (minimum ZiG500,000), corporates (minimum ZiG1,000,000), and banks (minimum ZiG10,000,000). The RBZ points to inflation now below 5% since January 2026 and surveys showing Zimbabweans are keeping ZiG in bank accounts longer as evidence that the timing is right.

But Austrian economists — a school of thought that has spent over a century analysing exactly this kind of central bank monetary engineering — would counsel deep caution. Their warnings are not abstract academic exercises. They speak directly to why the Mbuya (grandmother) who buried US dollars in a tin under her bed in 2008 made a more rational economic decision than any number of government economists predicted she would.

Böhm-Bawerk and the Time Value of Real Savings

The Austrian tradition begins with Eugen von Böhm-Bawerk, the nineteenth-century Austrian economist who developed the theory of capital and interest. His central insight was deceptively simple: interest rates reflect society’s genuine time preferences — the degree to which people actually prefer consuming now versus saving for the future.

When Zimbabweans choose to keep ZiG in a bank account for longer, as the RBZ’s own ZiG Perceptions and Confidence Survey II notes, that is a genuine signal of changing time preferences. People are making a real economic choice to defer consumption. That is healthy and organic.

But the ZiGDTDF does something different. It does not simply allow that organic savings behaviour to flow naturally through the capital markets. Instead, it channels it through the RBZ itself — the same institution that issues the currency. The RBZ becomes the intermediary between the saver in Chitungwiza and the capital that could fund a new factory in Msasa. Böhm-Bawerk would have recognised this as a fundamental distortion of the capital structure. The interest rate offered is not discovered by borrowers and savers interacting voluntarily in the market. It is set administratively by the same authority that controls the money supply. That is not a savings culture. That is a managed one — and managed things break in ways that organic ones do not.

Mises, the Interest Rate and Malinvestment

Ludwig von Mises, the titan of twentieth-century Austrian economics and author of Human Action, built on Böhm-Bawerk to develop what became the Austrian Business Cycle Theory. Its essence is this: when a central bank artificially manipulates interest rates — keeping them lower than what genuine savings would justify — entrepreneurs receive false signals. They invest in projects that appear profitable on paper but are unsupported by real savings in the economy. The inevitable result is malinvestment: capital poured into ventures that cannot be sustained once the monetary stimulus is removed.

Think of the construction boom of the 2000s in Zimbabwe, or the proliferation of import businesses during the multi-currency era that flourished not because of real productivity gains but because of favourable exchange rate arbitrage. When the conditions shifted, those businesses collapsed — not because of bad management, but because they were built on distorted price signals.

The ZiGDTDF is an Open Market Operations (OMO) instrument. Its explicit purpose is to absorb ZiG liquidity from the economy — to mop up money that the RBZ considers excess. But Mises would ask: excess by whose standard? The RBZ’s calculation of what constitutes the “correct” money supply is not a market discovery. It is an administrative judgment made by officials working with inevitably incomplete information. Every time the RBZ adjusts the quantity of ZiG through instruments like this one, it is sending a signal through the entire economy — to the hardware store owner in Gweru pricing inputs for the next quarter, to the farmer in Mvurwi deciding whether to expand, to the banker in Harare assessing loan risk. Those signals, filtered through a central planning mechanism rather than voluntary exchange, will misallocate resources in ways that may not become apparent for months or years.

Hayek’s Knowledge Problem and the Hubris of 5% Inflation

F.A. Hayek, who shared the Nobel Prize in Economics in 1974, warned about what he called the “pretense of knowledge” — the dangerous assumption that a central authority can possess enough information to manage a complex economy effectively. The RBZ’s announcement that inflation has been “sustained below 5% since January 2026” is presented as sufficient justification for launching this instrument. Hayek would have been sceptical.

Inflation statistics, as measured by official indices, cannot capture the subjective price experiences of millions of individuals operating in dispersed markets. The Mama who runs a tuck shop in Glen View knows that the cost of a 10kg bag of mealie meal moves differently from the official Consumer Price Index. The vendor at Machipisa market knows that transport costs since the ZiG introduction have varied in ways that no single statistic captures. The official 5% figure is an aggregation — useful as a rough guide, but dangerously misleading if treated as precise knowledge justifying major monetary policy instruments.

When the RBZ uses that figure as a green light for the ZiGDTDF, it is doing exactly what Hayek warned against: substituting a simplified data point for the complex, dispersed, and ultimately unquantifiable knowledge that exists in the everyday economic decisions of Zimbabweans.

Frank Shostak and the True Money Supply (TMS)

Among contemporary Austrian economists, Frank Shostak — chief economist at AAS Economics — has contributed important analytical tools to understanding monetary policy. His concept of the True Money Supply (TMS), developed in collaboration with Joseph T. Salerno, goes beyond conventional money supply measures (M1, M2) to capture the full stock of money available for immediate exchange in an economy.

Shostak’s framework would raise a specific and urgent question about the ZiGDTDF: what happens to the True Money Supply of ZiG when this instrument is operationalised? If the RBZ absorbs ZiG through 90-day deposits and simultaneously continues to issue ZiG through its other operations, the net effect on TMS may not be the stabilising contraction the RBZ intends. Shostak has consistently argued that central banks tend to underestimate the money supply they are actually creating because they do not account for all the channels through which monetary expansion occurs. The ZiGDTDF locks up existing ZiG for 90 days — but it does not prevent the RBZ from expanding the ZiG supply through other means during that same period. Zimbabweans, who lived through the era when the RBZ printed bearer cheques while simultaneously introducing savings bonds to “mop up” liquidity, will recognise the pattern.

Murray Rothbard: Sound Money Cannot Be Decreed

Murray Rothbard, author of What Has Government Done to Our Money? and arguably the most uncompromising voice in the Austrian tradition, would have delivered the bluntest verdict on the ZiGDTDF. For Rothbard, the entire premise of a central bank managing currency stability is fatally flawed — not because the people running it are incompetent, but because the institutional structure itself is incompatible with sound money.

Sound money, in Rothbard’s analysis, emerges from the market — historically from commodities like gold that have intrinsic value independent of any government decree. The ZiG is anchored to gold reserves held by the RBZ. That is, in principle, more sound than pure fiat. But Rothbard’s deeper point is about institutional trust: a currency is only as stable as the constraints on the authority that issues it. Zimbabwe’s monetary history — the Z$, the bearer cheques, the RTGS dollar, the Zimbabwe dollar 2.0, and now the ZiG — is precisely the history of those constraints failing, repeatedly, under the pressure of government spending needs.

No term deposit bill, however cleverly designed, changes that underlying institutional reality. When the government faces a fiscal crisis — a drought requiring emergency grain imports, a wage bill it cannot meet, an infrastructure project demanded by political constituencies — the temptation to expand the money supply does not disappear because there is an OMO instrument on the market. Rothbard would say: the ZiGDTDF is a policy built on the very institution whose unreliability created the need for the policy in the first place.

Joseph T. Salerno and the Regression Theorem

Joseph T. Salerno of the Mises Institute, a leading contemporary Austrian, has written extensively on the regression theorem — Mises’s explanation of how a money’s present value is always traceable back to its non-monetary use as a commodity. The ZiG derives its nominal gold backing from RBZ reserves. But Salerno would probe further: are those reserves independently audited? Are they genuinely free from the fiscal demands of the Treasury? Is the exchange rate at which ZiG is pegged to gold fixed by market discovery or administrative decree?

These are not merely technical questions. For ordinary Zimbabweans, they are existential. A salaried worker in Bulawayo who puts ZiG500,000 into a ZiGDTDF for 90 days needs to trust that at the end of those 90 days, the ZiG she receives back will purchase roughly the same basket of goods she could have bought today. Salerno’s framework reminds us that this trust cannot be manufactured by policy announcements. It must be earned through a sustained, credible, and independently verifiable track record of institutional restraint — something Zimbabwe’s monetary history has not yet provided.

What This Means for Everyday Zimbabweans

For the small business owner in Msasa industrial park, the ZiGDTDF presents a genuine short-term calculation: if inflation truly remains below 5% and the RBZ honours its commitments, a 90-day return on surplus ZiG could provide a modest hedge against cash depreciation. That is not nothing.

For the civil servant in Marondera whose salary arrives in ZiG and who cannot meet the ZiG500,000 minimum deposit, the instrument is simply irrelevant — a policy that, in its current structure, serves those who already hold substantial ZiG balances rather than the broad population the RBZ claims to be protecting.

For the pensioner in Harare’s eastern suburbs who remembers watching a lifetime of NSSA contributions dissolve in 2008, no 90-day return will rebuild the fundamental trust that was destroyed. For her, the Austrian economists are not theorists — they are voices describing her lived experience in academic language.

The Way Forward: Genuine Recommendations

Austrian economics is not merely a critique. It offers a coherent alternative framework. If Zimbabwe is serious about monetary stability and a genuine savings culture, the following steps are grounded in both Austrian theory and hard-won practical experience:

1. Independent Auditing of Gold Reserves. The ZiG’s credibility rests entirely on the gold reserves backing it. Those reserves must be subject to regular, independent, internationally recognised audits with results published transparently. Without this, the gold anchor is a claim, not a fact.
2. Strict Separation of Monetary and Fiscal Policy. The RBZ must be structurally insulated from Treasury borrowing. The history of Zimbabwean monetary collapse is, at its core, a history of the central bank financing government deficits. No OMO instrument can compensate for this fundamental structural weakness if it remains unaddressed.
3. Broaden Access or Abandon the Tiered Minimum. If the ZiGDTDF is genuinely about building a savings culture, the ZiG500,000 individual minimum must be dramatically reduced. A market-based micro-savings product, even at ZiG10,000, would do more to build genuine domestic currency confidence than an instrument accessible only to the already-wealthy.
4. Publish TMS Data. Following Shostak’s framework, the RBZ should publish comprehensive True Money Supply data monthly, including all ZiG-denominated instruments, deposits, and reserve positions. Transparency in the money supply is a precondition for informed economic decision-making by businesses and households.
5. Allow Market-Determined Interest Rates. Rather than administratively setting the return on the ZiGDTDF, the RBZ should allow competitive bidding to determine rates — letting the market signal what genuine savers require to willingly lock up capital for 90 days. This would produce a more accurate picture of actual time preferences in the ZiG economy.
6. Long-term: Constitutional Money Supply Constraints. Ultimately, following Rothbard’s prescription, Zimbabwe should explore constitutional or legislative caps on ZiG money supply growth tied to verifiable gold reserve growth — removing the discretionary power that has historically been abused.

Conclusion: Stability Must Be Earned, Not Announced

The RBZ’s slogan reads: “Stable. Secure. Sustainable.” These are aspirations, not achievements. The ZiGDTDF may be a well-intentioned instrument. The economists and officials behind it are, in all likelihood, genuinely trying to build something durable. But Böhm-Bawerk, Mises, Hayek, Shostak, Rothbard, and Salerno speak with one voice on the fundamental point: you cannot manufacture monetary credibility through institutional instruments alone. Credibility is the residue of restraint exercised over time, under pressure, when it was politically costly to exercise it.

Until Zimbabwe has that track record — and it is building it, slowly — every Zimbabwean who keeps a few extra rands in a sock drawer, every vendor who quotes in USD, every grandmother who distrusts the latest currency announcement is not being irrational. They are being Austrian economists, whether they know it or not.
