Ten Percent, Once, Without Warning – Part 2

A ten percent capital levy, imposed once and preferably without warning - what the International Monetary Fund calculated in 2013 has historical precedents. From Germany's Weimar Republic and the 1952 postwar wealth levy to Cyprus's banking crisis, government intervention in private wealth is far from hypothetical. Concrete political resolutions and legislative proposals have also emerged in Germany. Yet the IMF itself warned about the consequences. Michael Hollister examines why one-off wealth levies repeatedly return to the political agenda despite their historical failures - and the two obstacles that have prevented their widespread implementation.

Ten Percent, Once, Without Warning – Part 1

Part 1 reconstructed the International Monetary Fund’s 2013 calculation – approximately 10 percent of net wealth to return eurozone debt ratios to their pre-crisis levels – and showed that conditions are more strained today than they were then: higher global debt, a shrinking German economy, and a loosened fiscal regime. The decisive question remained unanswered: Was this calculation an isolated case, or does the state regularly resort to this instrument in exceptional circumstances? The answer begins not in 2013, but long before.

It Has Happened Before – More Than Once

A one-time wealth levy is not a thought experiment without precedent. It is a recurring instrument of the state in exceptional circumstances – and the Fund itself pointed to historical examples in its material.

Michael Keen expressly named those cases. Britain considered a capital levy after the Napoleonic Wars and again after World War I, when war debts had become crushing, although it was not implemented there. Germany resorted to one after World War I, and Japan after World War II. In German history, the line extends from the 1913 defense contribution through the 1919 Reich Emergency Levy to the 1952 Equalization of Burdens levy – which the Bundestag’s Research Services list as 1 of 3 historical examples of a wealth levy and classify as the only such levy imposed under the Basic Law to date.

The Reich Emergency Levy of 1919 is instructive because it demonstrates what can become of such a measure. The Weimar Republic imposed it to shoulder the burdens of war, but the inflation that followed ultimately devalued both the levy and the underlying debt. Keen himself identifies this pattern: Where capital levies were attempted, they were often preceded by prolonged debate and capital flight, accompanied by inflation that eroded the debt problem on its own. In other words, a state considering a capital levy has historically had 2 ways to rid itself of debt: It can take wealth from those who possess it, or allow monetary depreciation to consume it. Both ultimately strike savers, only in different ways.

The only case Keen regards as successful is Japan after World War II. The levy was imposed there in 1946 by the occupying power – and it worked for precisely that reason: It was largely free of democratic constraints, came as a surprise to those affected, and did not damage confidence in future Japanese governments because the occupation stood outside the normal political order. As Keen expressly stated, it was the exception, not the rule.

The 1952 Equalization of Burdens levy is the most immediate German blueprint. Introduced under Konrad Adenauer and collected until 1976, it amounted to 50 percent of wealth but was payable in installments over roughly 3 decades – an annual burden of approximately 1.67 percent, with substantial exemptions. It financed the consequences of the war and compensated displaced people and those whose homes had been destroyed by bombing. This was an instrument that the Federal Republic actually used and that remained in operation for a generation. The fact that it existed and functioned changes the nature of the debate: This is not a fantasy, but a tool bearing signs of previous use. Yet the other half of the historical record also matters, and Keen emphasized it: Capital levies were often considered, rarely imposed, and almost never successful. We will return to that in the counterargument.

The Quiet Return – London and Brussels

The idea did not disappear after 2013. It returned with the next major emergency, the COVID-19 pandemic – not at the fringes, but at the center of the debate.

In the United Kingdom, an independent Wealth Tax Commission placed the instrument back on the agenda in December 2020. Its recommendation was that if the government needed additional revenue to cover the costs of the pandemic, a one-time wealth levy would be preferable to other tax increases. A 5 percent levy on individual net wealth above £500,000, according to the calculation, could raise approximately £260 billion. It could alternatively be paid in installments over several years, at roughly 1 percent annually for 5 years. The commission’s rationale followed exactly the old logic: If a one-time levy arrived unexpectedly and credibly remained a one-time event, it would cause little behavioral distortion and would therefore be an efficient way to raise revenue. This was the same condition that had stood at the center of the discussion in 2013 – this time formulated not by the IMF but by a commission convened specifically for the issue.

At the European level, economists Camille Landais, Emmanuel Saez, and Gabriel Zucman proposed a temporary progressive wealth tax on the richest households in 2020 to finance the costs of the common pandemic response. It was intended to cover the top 1 percent, with rising rates for the top 0.1 percent and for billionaires; in their calculation, the revenue would repay common European debt over approximately 10 years. They expressly equated the proposal’s effect with a capital levy: It would burden wealth accumulated in the past without affecting current investment and would therefore be less damaging to growth than other forms of fiscal consolidation.

What is remarkable about these more recent proposals is that they carry the same fundamental condition as the Fund’s 2013 calculation: A one-time levy works cleanly in economic terms only if it arrives unexpectedly and credibly remains a one-time measure. The surprise logic of 2013 was not an outlier. It is the standard assumption in this literature, from Washington to London and the universities of Europe.

The wave did not remain confined to think tanks and commissions. Beginning in 2022, Spain introduced a temporary solidarity tax on large fortunes exceeding €3 million. In France, a report submitted to the prime minister in 2023 proposed a temporary wealth levy of 5 percent. A European overview of extreme-wealth taxation documents both debates. The instruments differ in their details – recurrent or one-time, high or low thresholds – but the underlying pattern is the same: In the post-pandemic environment of high debt and strained public finances, several European governments and advisory bodies turned toward the capital of the wealthy.

The instrument is neither new nor confined to one political camp, and it is not exclusively European. In Italy, Giuliano Amato’s government imposed an overnight levy on bank deposits in 1992 to stabilize the budget – a measure that predated the Cypriot intervention by 2 decades. Even in the United States, where taxing the stock of wealth is traditionally regarded as taboo, Donald Trump proposed a one-time 14.25 percent levy on wealth above $10 million in 1999 to reduce the national debt. These and other historical capital levies show that anyone who regards the one-time measure as an invention of the political left misunderstands its history. Governments and advisers of widely differing political persuasions reach for it whenever debt weighs heavily and rapid revenue is needed – from conservative cabinets to social democratic party conventions, from Rome and Washington to Berlin. That does not make it harmless. It merely makes it more predictable: Whenever public coffers are empty and growth is absent, it moves into the realm of the conceivable.

When the Levy Became Real – Cyprus in 2013

It did not remain a matter of model calculations. In the same year the Fund published its 10 percent figure, a eurozone member actually seized capital directly – although in a different form. During the rescue of the Cypriot banking sector in the spring of 2013, uninsured deposits above €100,000 at the Bank of Cyprus were made to absorb losses. In the course of the restructuring, the levy on those deposits was set at approximately 47.5 percent. Deposits below €100,000 remained protected.

This was not a general wealth levy modeled on the IMF box, and the distinction matters: In Cyprus, depositors at a distressed bank were affected as part of a bank resolution, rather than the net wealth of every citizen being taxed. The precise term is creditor participation – what specialists call a bail-in. For those affected, however, it was barely distinguishable from a one-time wealth levy: A substantial portion of the capital held in their accounts disappeared from one day to the next, by decision of the institutions supporting the rescue program. It happened quickly, accompanied by capital controls that prevented the money from being moved out of the country in time – under precisely the conditions the Fund had described as prerequisites for an effective levy: by surprise and before avoidance became possible. Cyprus demonstrated that direct access to capital in the eurozone is not merely contemplated but can be implemented under certain circumstances.

And in Germany

In Germany, too, calls for a one-time wealth levy remained alive after 2013 – and extended into a governing party.

At the beginning of the COVID-19 crisis in April 2020, former Social Democratic Party chairman Sigmar Gabriel raised the prospect of a new equalization-of-burdens measure, expressly invoking the postwar situation and the mobilization of private wealth at that time. In the same year, SPD co-chair Saskia Esken endorsed a solidarity wealth levy on the wealthiest. In 2022, Yasmin Fahimi, chairwoman of the German Trade Union Confederation, called for an equalization of burdens to finance the costs of the crises. That same year, Bremen Mayor Andreas Bovenschulte said he would welcome the issue of such a measure becoming a genuine political topic. These are not, it bears emphasizing, voices from the political fringes.

The most concrete document dates from October 2020. At the Berlin SPD state party convention on October 31, 2020, delegates adopted Motion 96/I/2020, titled “Wealth Levy for a Fairer Distribution of the Burdens of the Crisis.” Relying on Article 106 of the Basic Law, it calls for a one-time progressive wealth levy: an exemption of €500,000, a rate of 2.5 percent above that threshold, and 10 percent on wealth exceeding €25 million, with linear interpolation between the 2 rates. Owner-occupied homes serving as the principal residence would be exempt. To protect small and medium-sized businesses, company shares could also be transferred proportionately to the state so that businesses would not have to be sold to pay the levy.

The motion sets out the arithmetic behind its rationale, and the figures are revealing. Citing an estimate, it says that approximately 83,000 people in Germany owned one-fifth of the country’s total wealth – an average of roughly €31 million each and €2.6 trillion combined. The wealthiest 10 percent together held more than two-thirds of all assets, estimated at €8.6 trillion. If that wealth were correctly recorded, the levy would raise approximately €450 billion. The motion expressly states that it was intended to affect the wealthiest 10 percent of the population. Its explanation for choosing a levy rather than a recurrent tax is also notable: A wealth levy would have the advantage of causing large fortunes to be recorded again at all – a process that ceased when the recurrent wealth tax was suspended.

The same motion quotes Esken describing a one-time wealth levy as “one of the ways to put public finances back in order after the crisis.” This was not a demand from a splinter group, but one that the chairwoman of the chancellor’s party had publicly raised. The motion itself also invokes the historical precedent: Under Adenauer, a 50 percent wealth levy was introduced in 1952 and collected until 1976.

The political line is older and broader than the pandemic. In 2012, the Bundestag parliamentary group of Alliance 90/The Greens introduced a bill to impose a one-time wealth levy – Bundestag Printed Paper 17/10770 – expressly “modeled on the equalization of burdens,” at a rate of 15 percent payable over 10 years. An assessment by the German Institute for Economic Research found that the collection costs would be low, at less than 1 percent of the revenue. The Left also submitted a formal motion for a one-time wealth levy in the Bundestag, which the other parliamentary groups rejected. Across the years and several political parties, the same instrument repeatedly reappears – usually after debt has surged.

An important distinction is often blurred in public debate, and this article observes it strictly: The recurrent wealth tax, which has not been collected since 1997 following a ruling by the Federal Constitutional Court, is different from a one-time wealth levy. The first falls due year after year and taxes the same assets repeatedly; the second is imposed once, in a single operation. Anyone who conflates the 2 misunderstands both the constitutional position and the economic logic. This article concerns the second instrument throughout.

The Counterargument – and Why It Belongs Here

It would be dishonest to omit the other side. There are strong objections to a one-time wealth levy, and the sharpest comes from the Fund itself.

In 2013, Keen argued that capital levies had almost never worked historically. Governments had rarely imposed them in practice, and they had been “almost never” successful. The economist Barry Eichengreen, whose historical study Keen cited, identified only 1 successful case: occupation-imposed Japan in 1946. According to Keen, capital levies generally raised little where they were attempted because prolonged public debate and capital flight preceded them. The reason lies in the very requirement of surprise: Once citizens fear future levies, they move assets abroad, deplete them, or conceal them. The risk of further levies does not merely undermine the single measure; it damages the credibility of tax policy as a whole and discourages saving and investment. In practice, Keen concluded, a capital levy would therefore not be only mildly distortionary, but probably highly so – and that is precisely what makes it a poor instrument, however attractive the arithmetic may look on paper.

The legal and political situation in Germany is also clearer than some debates suggest. A one-time wealth levy would in principle be constitutionally possible; Article 106 of the Basic Law expressly recognizes it, and the Bundestag’s Research Services have examined the conditions such a levy would have to meet. There is currently no parliamentary majority for it. The CDU/CSU and Free Democratic Party oppose this form of taxation on the stock of wealth, and even under a different parliamentary composition, forming a majority without those parties would currently be difficult. In response to an inquiry by the Alternative for Germany parliamentary group, the federal government stated that the coalition agreement provided for neither an equalization-of-burdens measure nor a wealth levy. SPD member of parliament Carlos Kasper also rejected circulating rumors of a comprehensive equalization of burdens as unfounded; he said that there was no legal basis for a wealth levy.

Both statements are true and stand side by side: The instrument is demanded across party lines – and at present it fails for lack of a majority, not because the Constitution rules it out. An honest description of the situation retains both halves rather than playing one against the other.

Who Benefits from the Calculation

The question remains why an instrument that has almost never worked historically and currently lacks a majority is repeatedly brought back to the table. The answer lies less in intentions than in the structure of the situation.

The logic of a one-time wealth levy is distributive. On 1 side stands a state that must service its debts, together with the creditors whose claims must be honored. On the other stand those who own wealth, whose capital would be drawn upon once. The levy shifts burdens from the first group to the second. That is its essence, and it explains why the demand reliably grows louder where debt is high and current revenues are insufficient – and why it encounters resistance where accumulated wealth is defended politically. Viewed soberly, the dispute over the levy is a dispute over who pays the bill for a crisis.

The conditions underlying this distributional question have not eased since 2013. Global debt is higher, the German economy is contracting, the fiscal regime has been loosened, and spending pressures are rising at the same time – from the desired level of defense capability to the social burdens of an aging society. The narrower this gap becomes, the more attractive any instrument capable of mobilizing large sums at once will appear. This is not a prediction. It is a sober description of a conflict of interests on which the reader can form an independent judgment.

One detail of the debate speaks for itself: The fact that expert opinions repeatedly examine whether a wealth levy would be constitutional and whether a majority could be found does not mean that anyone is planning one. It does mean, however, that the question remains open enough to be asked repeatedly. Instruments that no one ever intends to use are not modeled with this regularity.

Two Barriers That Still Stood in 2013

What remains is the 2013 calculation and the question it leaves with the reader. In its own material, the Fund identified not only the levy’s attraction but also the barriers on which it fails in practice. Keen named 2.

The first: Introducing a new tax takes time, and a government can scarcely do so in complete secrecy. That gives people time to move wealth abroad, deplete it, or conceal it – the capital flight that undermines the levy’s yield. The second: The risk of future levies damages the credibility of tax policy as a whole and discourages saving and investment. Together, these 2 barriers explain why the levy has almost never been imposed in the past – and why even the Fund, which supplied the figure, ultimately advised against it.

This is where Part 2 ends – and where the real question begins. Whether these 2 barriers remain as high today as they were in 2013 is not a rhetorical question. It can be answered by examining concrete infrastructure: a digital identity currently being rolled out across Europe, a digital euro in preparation, asset and account registers whose interconnection is advancing step by step, and rules that make wealth harder to move abroad. The first barrier – capital flight – depends on how easily money can still be moved to safety. The second – advance warning – depends on how quickly and unexpectedly the state could gain access. Both involve technology and law, and both are changing. Whether the barriers of 2013 are falling – and what that means for a calculation that works only if it comes as a surprise – is the subject of Part 3.
