There are buildings whose ultimate owners cannot immediately be identified. Companies that report billions of dollars in profits in countries where they employ remarkably few people. Fortunes administered in one jurisdiction, legally held in another and invested in a third. Capital that crosses several borders without its ultimate beneficiary ever having to move.

None of this necessarily requires breaking the law.

That is precisely what makes the phenomenon so difficult to understand and regulate. The global economy has gradually developed a sophisticated collection of legal and financial instruments capable of separating the legal ownership of an asset from its economic control, management, location and taxation. These instruments facilitate investment, protect certain forms of wealth and make complex international transactions possible. They can also conceal beneficial owners, artificially transfer profits, remove income from the tax base or obscure the origins of criminal proceeds.

Capital does not have to become invisible to escape scrutiny. Sometimes, it merely has to become legally difficult to trace.

The amounts involved are considerable. In its State of Tax Justice 2024 report, the Tax Justice Network estimated that international tax abuse costs governments approximately $492 billion annually. Of that total, roughly $348 billion was attributed to multinational corporate profit shifting and $145 billion to offshore tax abuse involving private wealth. These are model-based estimates, not an inventory of judicially established tax offences, but their scale illustrates the magnitude of the problem.

The OECD reveals another striking imbalance. Its Corporate Tax Statistics 2025, drawing on country-by-country reporting for the 2022 financial year from more than 8,700 multinational enterprise groups, show that investment hubs accounted for approximately 18% of reported foreign profits but only 4% of employees and 12% of tangible assets. Median profit per employee reached $85,000 in these jurisdictions, compared with $18,000 elsewhere.

These disparities do not automatically demonstrate fraud. They nevertheless reveal a fundamental separation between the places where economic activity takes place, where profits are recorded and where taxes are paid.

The question is therefore no longer simply where money is located. It is how the law allows its economic identity to be transformed.

Ownership Is No Longer Self-Evident

In its simplest form, ownership appears easy to establish. An individual owns a company, which holds assets, receives income and pays taxes. The owner appears in corporate registers, the company in financial statements and its earnings in tax returns.

International finance has made this representation increasingly inadequate.

A company may belong to a holding company, itself owned by another corporation whose shares are administered by a fiduciary or incorporated into a trust. Voting rights may be separated from dividend entitlements. One individual may control an asset without appearing as its immediate legal owner. Another may be designated as the owner without exercising genuine decision-making authority.

Four concepts must therefore be distinguished: legal ownership, economic entitlement, effective control and beneficial ownership as defined under applicable transparency rules.

These categories may coincide. They may also be distributed among several individuals or entities.

Consider a building purchased for €40 million in a European capital. The property register identifies a domestic company as its owner. That company is held by a Luxembourg holding company, itself controlled by an entity incorporated in another jurisdiction. At the top of the structure sits a trust whose assets are administered by a professional trustee for the benefit of several individuals.

Such an arrangement may serve entirely legitimate purposes: succession planning, bank financing, investor pooling or wealth management. It may also complicate the identification of the person exercising ultimate control if information is not properly collected, verified and made accessible.

The multiplication of legal entities does not necessarily make the owner unknowable. It makes identification dependent on cooperation among corporate registries, banks, tax administrations and judicial authorities.

That dependence is where opacity begins.

Shell Companies: The First Layer of Invisibility

A shell company is often imagined as a fictitious business established on a tropical island. The reality is more complex.

A company may be legally incorporated, maintain a bank account, own investments and comply with its formal obligations while conducting very limited operational activity. Asset-holding companies and special-purpose vehicles are common in real estate transactions, project finance, securitisation and corporate acquisitions.

Their existence is not inherently suspicious.

The difficulty arises when their actual economic purpose cannot be established, when their management is purely nominal or when they are used to insert layers between an asset and its true controller.

One company may own another, which owns a third. At each level, publicly accessible records may reveal only the immediately preceding legal owner. Identifying the ultimate beneficial owner then requires tracing the entire chain, sometimes across jurisdictions with different disclosure requirements.

Professional directors, nominee shareholders, private agreements and share classes carrying different voting and economic rights can add further complexity.

A professional director is not necessarily an unlawful nominee. But when the person named in official documents is not the individual actually issuing instructions, formal transparency may become misleading.

The Financial Action Task Force, or FATF, regards the misuse of legal persons and legal arrangements as a major vulnerability in the fight against money laundering, corruption and terrorist financing. Its Recommendations 24 and 25 require countries to ensure that competent authorities can obtain adequate, accurate and up-to-date beneficial ownership information.

The problem is not the existence of an intermediary company. It arises when that company ceases to be an organisational instrument and becomes an obstacle to identifying who actually exercises power.

Trusts, Foundations and Ownership Without an Apparent Owner

The trust is among the most characteristic instruments of this separation.

Rooted in common-law legal traditions, it generally involves a settlor who transfers assets into the arrangement, a trustee who administers them under applicable rules, and beneficiaries who may receive economic advantages.

The settlor, trustee, beneficiaries and, where applicable, protector may reside in different countries. Their respective powers and economic rights depend on the trust deed, governing legislation and arrangements actually implemented.

Trusts serve genuine purposes. They can organise complex inheritances, protect vulnerable individuals, manage family wealth and separate personal assets from business interests.

But they can also make ownership difficult to reconstruct.

The settlor's identity does not always establish who exercises control. The trustee may legally hold assets without being their economic beneficiary. Beneficiaries may be defined as a class or possess conditional entitlements.

Private foundations and other wealth-management arrangements can pursue comparable objectives through different legal mechanisms.

It would be incorrect to claim that such structures inherently escape disclosure obligations. Anti-money-laundering rules and international tax-reporting frameworks increasingly require the identification of several categories of persons connected to trusts.

The real question concerns enforcement: who collects the information, who verifies it, who may access it and how quickly can it be obtained when an investigation crosses multiple borders?

Modern opacity does not always depend on the absence of documentation. It may result from documentation being scattered across jurisdictions.

Tax Havens Are Not All Islands

The Cayman Islands, Bermuda and the British Virgin Islands occupy a prominent place in the popular imagination of offshore finance. Yet reducing the offshore system to a handful of island territories would fundamentally misunderstand its architecture.

Tax and regulatory competition also operates at the heart of major economies.

Luxembourg hosts numerous cross-border holding and investment structures. The Netherlands has historically played a major role in international dividend, interest and royalty flows, although its anti-abuse rules have been strengthened. Ireland has established itself as a European centre for technology and pharmaceutical groups. Switzerland retains a central position in international wealth management. Singapore and the United Arab Emirates have developed into major platforms for capital, regional headquarters and financial services.

In the United States, states such as Delaware offer particularly attractive corporate-law infrastructure, without implying that companies incorporated there automatically enjoy tax exemptions or complete anonymity.

These jurisdictions are neither legally equivalent nor interchangeable. Some attract corporate headquarters and intangible assets; others specialise in investment funds, private wealth, financing vehicles or holding companies.

The term tax haven itself encompasses several different realities: low or zero taxation, preferential regimes, confidentiality, flexible corporate law, extensive tax-treaty networks and the ability to host structures with limited economic substance.

An advantage may derive from a reduced tax rate, but also from how income is classified, how treaties apply or how particular entities are treated under different legal systems.

There is consequently a geography of production and another geography of ownership.

The first can be measured through factories, employees, ports, offices and infrastructure. The second through holding companies, shareholdings, intellectual-property rights, contractual arrangements and financial flows.

The two geographies no longer necessarily overlap.

Profits Travel More Easily Than Factories

It is within multinational corporations that this separation produces some of its most measurable consequences.

A factory must be built somewhere. It employs workers, consumes electricity, imports components, uses roads and occupies physical territory. Its material existence cannot easily be relocated.

Accounting profit, by contrast, depends partly on how revenues and expenses are allocated among the group's legal entities.

Transfer pricing is the principal mechanism governing that allocation. It determines the terms under which companies belonging to the same group exchange goods, services, financing or intellectual-property rights.

The internationally recognised standard is the arm's-length principle: related-party transactions should reflect conditions comparable to those that independent enterprises would have agreed under similar circumstances.

Implementation becomes difficult when the assets involved are unique, comparable transactions are scarce or economic functions are distributed across multiple countries.

Consider an industrial company generating €500 million in annual revenue in a country where the corporate income-tax rate is 30%.

Before certain intragroup expenses, its taxable profit would amount to €80 million, producing a theoretical tax liability of €24 million.

Now suppose the company incurs €20 million in brand royalties, €15 million in management fees and €10 million in interest payments to related entities.

Its taxable profit falls to €35 million, and the corresponding tax liability to €10.5 million.

The difference amounts to €13.5 million.

This is an illustrative calculation, not evidence of an unlawful tax saving. If the services are genuine, the financing economically justified and the prices consistent with the arm's-length principle, the expenses may be legitimate. Interest deductions may also be subject to specific statutory limitations.

However, if these charges are artificially inflated, inadequately documented or economically unjustified, they can become instruments of tax-base erosion.

The distinction is essential. An intragroup transaction is not abusive simply because it reduces local profits. It becomes problematic when it fails to reflect economic reality or breaches applicable tax rules.

This mechanism helps explain how a subsidiary can employ hundreds of people, use a country's infrastructure, report substantial turnover and nevertheless declare very limited taxable profits.

The phenomenon is not confined to developing countries. Its consequences may, however, be particularly significant where corporate income tax represents an important source of public revenue and tax administrations have more limited enforcement resources.

Industrialisation can then generate employment and exports without producing tax revenues proportionate to the economic activity genuinely conducted within the territory.

Intangible Assets and the New Geography of Economic Rents

Brands, patents, software, algorithms, databases and other intangible assets have profoundly transformed international taxation.

Unlike a factory, a patent or licensing right may be legally held by an entity separate from the company manufacturing or selling the products.

A corporation may develop technology in one country, organise certain contractual rights in another and charge royalties to subsidiaries exploiting those rights elsewhere.

The legitimacy of this allocation depends on the functions actually performed, assets employed, risks assumed and applicable transfer-pricing rules. Legal ownership alone is insufficient to justify attributing all associated profits to a particular entity.

The OECD has therefore strengthened its analysis of the functions involved in the development, enhancement, maintenance, protection and exploitation of intangible assets, commonly referred to as DEMPE.

This approach seeks to align taxable remuneration more closely with genuine economic contributions.

The challenge remains considerable. How should one determine the value of a unique algorithm, a global brand or a technology for which no comparable independent transaction exists?

The answer depends on valuation models, assumptions about future earnings, functional analyses and comparisons that may themselves be disputed.

The more economic activity depends on assets that are difficult to locate and value, the more complicated it becomes to determine where profits should be taxed.

Intellectual property is therefore not merely an industrial resource. It has also become a central issue in the international allocation of tax revenues.

Debt as a Mechanism of Profit Transfer

Profits can also be shifted through financing arrangements.

A subsidiary may borrow from a related company established abroad. It pays interest that, subject to applicable rules, reduces its taxable income. The lending entity records financial income that may be subject to a different tax regime.

Such arrangements can represent ordinary financing. Multinational groups frequently centralise treasury operations to reduce costs, secure liquidity and allocate financing efficiently.

But excessive debt, abnormal interest rates or lending entities lacking genuine financial functions may trigger tax adjustments.

Tax authorities therefore seek to establish whether independent parties would have accepted comparable financing conditions, whether the subsidiary has credible repayment capacity and whether interest deductions comply with statutory restrictions.

Under Action 4 of the BEPS project, the OECD recommends mechanisms limiting net interest deductions in relation to economic earnings, subject to national implementation.

Intragroup debt illustrates a fundamental difficulty: what constitutes a deductible expense for one company is income for another. When the two operate under different tax systems, mismatches may create opportunities for tax arbitrage.

Hybrid financial instruments and hybrid entities introduce further complexity. The same payment may receive different legal or fiscal treatment in the debtor's country and the recipient's jurisdiction. Anti-hybrid rules seek to prevent these differences from producing deductions without corresponding income inclusion or duplicate deductions.

Tax engineering thus often exploits not the absence of law, but differences between legal systems.

Private Wealth: Owning Without Appearing

The mechanisms used by multinational corporations are not identical to those employed in private wealth management.

For wealthy individuals and families, objectives may include inheritance planning, international diversification, confidentiality, protection against certain legal risks or continuity of asset management.

A family may hold financial investments through a holding company, own real estate through dedicated corporate vehicles and place part of its wealth within a trust or foundation.

Confidentiality can serve legitimate concerns relating to personal security and privacy.

Yet the same instruments may also be misused to conceal undeclared assets, frustrate lawful seizure or obscure conflicts of interest.

The distinction between confidentiality and concealment depends, among other factors, on whether authorised authorities can obtain reliable information and whether reporting obligations are fulfilled.

This is particularly important for politically exposed persons, public procurement beneficiaries, executives of state-owned companies and individuals with privileged access to public resources.

Apparently private ownership may then raise questions about the origin of funds, connections to public decisions and possible unexplained enrichment.

Identifying a beneficial owner does not itself establish wrongdoing. It does, however, provide an essential starting point for investigating conflicts of interest, corruption and illicit financial flows.

When Opacity Meets Organised Crime

Money laundering pursues a different objective from tax optimisation.

It involves giving an appearance of legitimacy to proceeds derived from criminal activity. Complex legal structures may help conceal their origin, movement or ultimate destination.

Traditional analysis distinguishes placement, layering and integration. In practice, these stages do not always occur sequentially or in clearly identifiable forms.

Real estate, commercial companies, investment structures and international transactions may be misused to introduce illicit funds into apparently ordinary economic activity.

For authorities, the challenge is distinguishing genuine commercial transactions from arrangements whose economic justification is fictitious or disproportionate.

The United Nations Office on Drugs and Crime has historically cited an estimated annual money-laundering range equivalent to 2–5% of global GDP. This widely repeated range is based on older and highly uncertain estimates and should not be presented as a verified current measurement.

The clandestine nature of money laundering makes reliable quantification exceptionally difficult. Nor would it be methodologically sound to add estimated laundering volumes directly to estimated tax losses: the two measures describe different phenomena, may overlap and rely on different methodologies.

What can be established is that companies, trusts and other legal arrangements can be misused to conceal individuals involved in criminal activities.

Beneficial ownership transparency has consequently become a central component of international financial security.

The Intermediaries: An Industry Built Around Complexity

No international wealth structure operates through legal texts alone.

It requires professionals: lawyers, accountants, tax advisers, banks, corporate administrators, wealth managers, trustees, registered agents and corporate service providers.

These professions perform essential functions. They ensure compliance, secure transactions, organise investment and enable companies to operate across multiple legal systems.

Their position can also place them at the centre of concealment risks.

A professional may establish a structure without adequately identifying its ultimate beneficiary, accept insufficient economic justification or fail to detect inconsistencies in the source of funds.

Know-your-customer requirements, enhanced due diligence and suspicious-transaction reporting obligations are intended to reduce precisely these vulnerabilities.

The issue therefore extends beyond the responsibility of capital owners. It also concerns the quality of oversight exercised by the institutions enabling capital to circulate.

Financial globalisation has created an entire industry of legal structuring. Regulation must ensure that this industry does not, deliberately or through negligence, provide opacity incompatible with legitimate transparency requirements.

The Panama Papers: When the Archives Exposed the System

In April 2016, an international journalistic investigation brought the Panama Papers into public view. The documents originated from Mossack Fonseca, a Panamanian law firm specialising in the incorporation and administration of offshore structures.

Coordinated by the International Consortium of Investigative Journalists, the investigation drew on 11.5 million documents representing approximately 2.6 terabytes of data. It uncovered information concerning more than 214,000 offshore entities connected to people in over 200 countries and territories.

The volume of material was extraordinary. Its significance extended well beyond its size.

The documents illustrated how legally distinct companies could be incorporated, administered and used to hold bank accounts, investments and other assets. They also exposed the role of professional intermediaries in establishing and maintaining these arrangements.

Five years later, the Pandora Papers substantially expanded the picture.

Published in 2021, the investigation was based on 11.9 million documents, totalling approximately 2.94 terabytes, obtained from fourteen offshore service providers. The material covered individuals and assets connected to more than 200 countries and territories. Among those identified were more than 330 politicians and public officials and 130 billionaires appearing on Forbes rankings.

These revelations did not establish that every individual mentioned had committed an offence. Offshore company ownership can be entirely lawful, and inclusion in leaked documents does not constitute a criminal conviction.

They nevertheless exposed a structural reality: the offshore wealth-management industry does not operate outside the financial system. It relies on specialised service providers, banking institutions, recognised legal instruments and international professional networks.

Successive investigations also demonstrated the limitations of transparency systems based solely on formal disclosure obligations. When the identity of ultimate asset owners becomes visible to the public only through massive leaks of confidential records, the effectiveness of official oversight inevitably comes into question.

The significance of these scandals lies not only in the individual conduct they revealed, but in the existence of a global infrastructure capable of separating wealth from public visibility.

Governments Confront the Mobility of Capital

Governments have gradually strengthened their instruments of financial oversight.

The first level concerns identification.

Beneficial ownership registers are intended to establish which natural persons ultimately own or control legal entities. Their effectiveness depends on disclosure thresholds, verification procedures, sanctions and the access granted to competent authorities.

A 25% ownership threshold, frequently used in certain regulatory frameworks, does not constitute a universal definition of control. An individual may exercise decisive influence through a smaller shareholding, particularly through voting agreements or special rights.

The second level concerns banking transparency.

The Common Reporting Standard, developed under the OECD, provides a framework for the automatic exchange of information on financial accounts held abroad.

According to figures published in 2025, 116 jurisdictions had begun exchanging information. During 2024 alone, these exchanges covered more than 171 million financial accounts representing nearly €13 trillion in assets.

The OECD has also reported that voluntary disclosure programmes and other offshore tax-compliance initiatives have generated more than €135 billion in additional taxes, interest and penalties since the international commitments to implement automatic exchange.

These figures demonstrate that transparency can produce measurable results.

They do not mean that all foreign wealth is now identifiable. Exchanged information must be properly processed, intermediary structures understood and the resulting data cross-checked against domestic tax declarations.

The third level concerns multinational taxation.

The OECD/G20 Base Erosion and Profit Shifting project seeks to limit the artificial erosion of tax bases and the transfer of profits between jurisdictions.

Its measures address transfer pricing, hybrid mismatches, interest deductibility, tax-treaty abuse and country-by-country reporting, among other issues.

Country-by-country reports allow tax administrations to examine the distribution of revenues, profits, taxes, employees and assets across the jurisdictions in which large multinational groups operate.

The underlying change is important.

A company can no longer be assessed exclusively through the isolated financial statements of its local subsidiary. Authorities increasingly need to understand that subsidiary's position within the wider multinational group.

Reporting, however, is not a substitute for enforcement. It provides the information necessary to make enforcement possible.

Global Minimum Taxation: The End of Tax Havens?

The introduction of a 15% global minimum tax for large multinational groups represents a major development in international taxation.

The Pillar Two framework, generally applying to groups with consolidated annual revenues of at least €750 million, seeks to reduce the tax advantages associated with locating profits in very low-tax jurisdictions.

Its mechanism is based on calculating an effective tax rate under common rules and, where applicable, imposing a top-up tax.

This does not mean that every company worldwide is subject to a uniform 15% tax rate, or that every euro of profit receives identical treatment.

The framework contains exclusions, adjustments, substance-based provisions and implementation mechanisms that vary across jurisdictions.

Subsequent international negotiations, including so-called side-by-side arrangements, have also made it necessary to distinguish the original design of the framework from its actual implementation.

In July 2026, the OECD published an updated economic assessment of the global minimum tax.

According to its simulations, the current framework could reduce profit shifting by between 22.6% and 44.6% compared with a hypothetical situation without the minimum tax.

Global corporate income-tax revenues could increase by approximately 3.2% to 5.4% annually.

Average effective tax rates could rise by 2.8 to 3.7 percentage points, with a larger estimated increase of 5.5 to 6.9 percentage points in investment hubs.

These figures are projections, not a record of revenue already collected.

Initial observations from 2024 suggested higher effective tax rates for affected companies, without statistically significant evidence of reduced investment or employment during that first year.

The reform may therefore diminish the attractiveness of certain tax-planning structures. It does not eliminate differences between tax systems, competition among jurisdictions or the difficulties associated with identifying beneficial owners.

More fundamentally, taxation and ownership opacity are not exactly the same problem.

Capital may be properly taxed while its ultimate owner remains difficult for the public to identify. Conversely, a fully transparent company may legally exploit differences between national tax systems.

Transparency and taxation must be considered together, but they are not interchangeable.

Host Countries: Attracting Investment Without Losing the Value

The issue becomes particularly important for economies seeking to attract foreign capital.

An international company may bring machinery, technology, access to export markets, expertise and employment opportunities.

These benefits are real, even when the parent company organises ownership and financing from abroad.

But the host government must determine how much of the value generated locally remains within its economy.

An industrial subsidiary may record substantial turnover while paying brand royalties, headquarters management fees, information-technology charges, intragroup interest and commercial commissions.

Each payment may be legitimate. Their cumulative effect can nevertheless significantly reduce locally taxable profits.

The implications extend beyond corporate income tax.

They concern foreign-exchange reserves, dividend distributions, technological dependence, local procurement and the subsidiary's ability to finance its own development.

Host countries possess several regulatory instruments: transfer-pricing documentation, scrutiny of service agreements, withholding taxes where applicable, limitations on financial deductions, beneficial ownership verification, exchange controls under national law and cooperation among tax authorities.

Advance pricing agreements can reduce uncertainty, while mutual agreement procedures between tax administrations can help prevent or resolve double taxation.

Effective regulation must nevertheless avoid two mistakes.

The first would be to treat every intragroup payment as an illegitimate capital outflow. A subsidiary may genuinely benefit from technology, branding, financing and services that it could not efficiently develop independently.

The second would be to assume that every contract signed between related companies necessarily reflects normal economic conditions.

The quality of oversight therefore depends on the tax administration's ability to understand the business model, the functions performed and the risks assumed by each entity.

For emerging economies, this capacity is becoming an instrument of sovereignty as important as industrial policy itself.

A country can attract factories without necessarily controlling the distribution of the profits they generate. It can receive investment while remaining legally, financially and technologically dependent on decision-making centres abroad.

The challenge is not to choose between openness and isolation.

It is to build institutions capable of converting international investment into lasting domestic value creation.

Competition Between Sovereignties

Offshore finance also thrives on differences between states.

Each jurisdiction possesses its own corporate law, tax regime, inheritance rules, reporting obligations and judicial procedures.

These differences reflect sovereign choices. They also allow investors to select legal environments suited to their requirements.

Yet when several legal systems interact, their inconsistencies can create advantages that no individual jurisdiction necessarily intended to produce.

An entity may be fiscally transparent in one country and treated as opaque in another. A payment may receive different legal classifications. A tax treaty may produce different consequences depending on residence, economic substance or the identity of the income's beneficial owner.

Anti-abuse rules seek to limit such outcomes, but they must operate within national systems that remain only partially harmonised.

A fundamental asymmetry consequently persists.

Capital can be organised globally, while tax administrations, courts and supervisory authorities remain predominantly national.

International cooperation seeks to narrow that gap. It nevertheless depends on political agreement, administrative capacity and governments' willingness to exchange information that may be commercially or politically sensitive.

Tax competition is not necessarily synonymous with concealment.

It can attract productive investment, encourage innovation and provide incentives for more efficient tax systems.

But when competition depends on inadequate transparency or arrangements lacking genuine economic substance, it can alter the international distribution of public revenues.

Jurisdictions hosting profits may collect taxes associated with economic activity substantially conducted elsewhere.

Countries providing labour, consumers and infrastructure may, in turn, recover only part of the tax base connected to that activity.

Financial globalisation thus becomes a mechanism for redistributing taxing rights across borders.

An Economy of Selective Visibility

The evolution of international regulation reveals a deeper transformation in the relationship between wealth and power.

For decades, banking confidentiality and freedom of patrimonial structuring were regarded as important attributes of international finance.

They remain legitimate when they protect privacy, secure transactions or facilitate investment.

But using those protections to prevent competent authorities from identifying ultimate owners, verifying the origins of funds or establishing tax liabilities raises a question of public interest.

Transparency does not necessarily require universal public disclosure of every private fortune.

At a minimum, it requires competent authorities to obtain reliable information promptly, verify it and use it within a framework that respects legal safeguards.

The effectiveness of the system depends less on the number of registers created than on their accuracy, interoperability and the capacity of administrations to convert information into meaningful oversight.

Money is not inherently opaque.

The structures through which it is owned, the rules governing its movement and the institutions responsible for supervising it determine how visible it becomes.

Recent reforms have begun to reduce certain areas of opacity.

Automatic information exchange, beneficial ownership requirements, country-by-country reporting and global minimum taxation all reflect a shift in international policy.

Yet the data continue to reveal a significant separation between the location of reported profits and the geography of productive activity.

Investment hubs remain jurisdictions where profits are disproportionately high relative to employment and tangible assets. International private wealth remains difficult to measure precisely. Cross-border investigations require complex cooperation, while tax rules frequently evolve more slowly than the financial arrangements they seek to regulate.

It would be excessive to conclude that financial globalisation is entirely based on concealment.

The same instruments help finance companies, build infrastructure, organise inheritance and mobilise international savings.

But it would be equally mistaken to regard opacity as a marginal accident.

It can become an economic advantage when legal complexity allows certain actors to reduce their obligations or escape scrutiny to which others remain subject.

This asymmetry reaches the foundations of fiscal sovereignty.

A state may establish tax rates, enact legislation, negotiate treaties and strengthen its administration. But if profits can be transferred beyond its effective reach, or if the ultimate beneficiary of an asset cannot be identified, its power to tax becomes partly theoretical.

The global economy has made ownership extraordinarily mobile.

It has not yet developed an equally effective capacity to establish accountability wherever that ownership travels.

Capital has therefore not truly disappeared.

It continues to finance assets, generate income, exercise rights and create obligations.

What may disappear behind companies, contracts and borders is the immediately visible connection between wealth and the person who ultimately controls it.

And when that connection is broken, the question is no longer simply who owns the money.

It becomes who still possesses the power to demand an account of it.
