There is a lot more to havens than crystal-clear waters and a promise of opacity

In June 2025, a deadline passed that was supposed to mark a turning point. The United Kingdom had demanded that its Overseas Territories — the British Virgin Islands, the Cayman Islands, Bermuda — establish publicly accessible registers of beneficial ownership by that date. All three missed it. A Foreign Office minister called the outcome “progress.” He welcomed the compliance of St Helena and the Falkland Islands, two territories with a combined handful of registered companies. The three jurisdictions that actually matter — that between them host trillions of dollars in offshore structures — simply carried on. The offshore finance industry, it turns out, is extremely good at absorbing pressure while changing remarkably little.

The reforms were real. The pressure was genuine. Since the 2009 G20 summit in London, governments have pushed hard for a more transparent global financial system, deploying everything from automatic information exchange to blacklists and the sweeping architecture of the OECD’s Base Erosion and Profit Shifting (BEPS) project. The 15% global minimum corporate tax under Pillar Two began applying from January 2024, with over 135 jurisdictions formally signed up.

Yet the money kept moving offshore. According to the EU Tax Observatory, $12 trillion — equivalent to roughly 12% of world GDP — was held offshore by households at the end of 2022, a figure that excludes real assets such as art, yachts, or real estate. A more recent Oxfam analysis suggests global offshore wealth reached $13.25 trillion in 2023, with as much as $3.55 trillion potentially concealed from tax authorities. These are not numbers heading in the right direction for reformers. TaxobservatoryBreezyScroll

Why Are Offshore Tax Havens Still Thriving Despite Global Crackdowns?

Offshore finance thrives because the industry does not resist change — it incorporates it. The offshore financial centres of 2025 are no longer selling secrecy as a primary product. They are selling legal compliance infrastructure, governance structures, and regulatory arbitrage that operates entirely within the letter of international rules. The crackdowns made havens evolve; they did not make them disappear.

The Core Development: Adaptation, Not Extinction

The template of the classic tax haven — a sun-drenched island, a brass-plate company, an anonymous numbered account, and an absolute refusal to answer questions — is largely gone. What replaced it is more sophisticated and, crucially, harder to attack.

The Cayman Islands offers the clearest illustration. The Cayman Islands’ Beneficial Ownership Transparency Act and its accompanying regulations came into force on 31 July 2024, replacing the previous beneficial ownership regime and creating a consolidated legal framework that, on paper, aligns with international standards set by the Financial Action Task Force (FATF). In the BVI, sweeping changes to beneficial ownership reporting came into effect on 2 January 2025, requiring entities to file details of their beneficial owners directly with the Registry of Corporate Affairs rather than with private registered agents — a structural shift in accountability that would have been unthinkable a decade ago. OgierOgier

That is the glass-half-full reading. The glass-half-empty version matters more.

Compliance and transparency, in this context, are not the same thing. Historically, beneficial ownership information in the BVI remained largely confidential, with only competent authorities and law enforcement agencies able to access beneficial ownership information — and even the July 2025 amendments merely extended access to third parties demonstrating “legitimate interest,” a term whose definition remains contested and narrow. A journalist, a civil society researcher, or an ordinary citizen cannot freely search who owns what. Ogier

Professor Jason Sharman of Cambridge, one of the world’s leading authorities on offshore finance, is blunt about the overall picture: “Offshore financial centres in general are doing fine. There is probably more money offshore than ever before — subject to the caveat that it is harder than it might seem to distinguish ‘offshore’ from ‘onshore.'” World Finance

That caveat contains a story of its own.

The Structural Shift: From Secrecy to Substance — and Why It Changes Less Than You’d Think

The OECD’s Pillar Two global minimum tax is the most ambitious piece of international tax architecture in a generation. By imposing a 15% effective rate on multinational enterprise groups with revenues above €750 million, it was designed to sever the link between where profits are booked and where taxes are paid. Many jurisdictions have taken steps to implement these rules into domestic law, with the global minimum tax starting to apply from the beginning of 2024 through the Income Inclusion Rule. OECD

Yet the architecture has a structural weakness: it targets large multinationals, not the vast majority of offshore finance activity. Private wealth held through trusts and family offices, the preferred vehicles of the ultra-rich, sits largely outside Pillar Two’s scope. Offshore structures remain useful for governance, asset protection, and operational flexibility — not just tax optimisation. Substance, transparency, and banking acceptance now play a bigger role than ever. Structures that are clear, explainable, and aligned with real activity are far more resilient under Pillar Two rules.

What this means, in practice, is that the industry shifted its sales pitch. The pitch is no longer “hide your money.” It is “structure your money correctly.” The distinction sounds lawyerly because it is — and that is precisely the point.

Why does offshore wealth keep growing despite transparency rules? Offshore finance persists because transparency frameworks and tax rules address different problems imperfectly. Automatic information exchange catches declared accounts in cooperating jurisdictions but cannot easily reach trust structures, real assets, or entities layered across multiple non-cooperating jurisdictions. Pillar Two covers large corporations but not private wealth. Each reform closes one gap and, inadvertently, signals where the remaining gaps are.

Implications: The Geography of Money Is Being Redrawn

The most consequential second-order effect of the crackdown era isn’t that offshore finance shrank. It’s that it moved — to places with better reputations, better infrastructure, and better lawyers.

Singapore is the most important beneficiary. HSBC’s 2025 Affluent Investor Snapshot, drawing on data from nearly 11,000 investors across 12 markets, confirmed Singapore’s emergence as the top choice in Asia for affluent investors opening overseas accounts, ranking alongside the United States and Hong Kong as one of the three most preferred destinations globally. Singapore is not conventionally understood as a tax haven. It has a corporate tax rate of 17%, maintains FATF compliance, and participates in automatic information exchange. It is also a jurisdiction where private wealth management operates with a level of discretion, regulatory clarity, and legal sophistication that rival jurisdictions cannot match. It combines the appearance of legitimacy with the functionality of a haven. Hsbc

The UAE is the even more striking case. According to Henley & Partners, the UAE is forecast to attract a net inflow of around 9,800 millionaires in 2025, bringing an estimated $63 billion in investable wealth, as the Dubai International Financial Centre emerges as the jurisdiction of choice for international families and corporates. The UAE’s zero income tax, residency-by-investment programmes, and modern trust law make it simultaneously a lifestyle destination and an offshore finance hub — a combination that is extraordinarily difficult for regulators to target.

Then there is the United States. South Dakota, by 2025, has accumulated trust assets running into hundreds of billions of dollars, shielded by perpetual trust laws and among the loosest disclosure requirements of any developed jurisdiction. Delaware incorporations continue to offer minimal transparency to non-US inquirers. The country that leads the charge against offshore abuse is itself, by any objective measure, one of the world’s significant offshore finance destinations. That contradiction is not lost on reformers — and it substantially weakens Washington’s moral authority when pressing smaller jurisdictions to comply.

Gabriel Zucman of the EU Tax Observatory proposed in 2024, at the G20 Finance Ministers’ meeting in Brazil, that billionaires be required to pay a minimum of 2% of their wealth in taxes annually. The proposal targets around 3,000 billionaires globally and is estimated to raise an additional $250 billion a year in revenues, primarily in the richest countries where the great majority of billionaires reside. In November 2024, the G20 leaders gave it lukewarm endorsement. The Trump administration’s posture toward global tax coordination has since complicated the picture considerably. Tax Justice Network

The Counterargument: Reformers Have Made Real Gains

It would be a mistake to dismiss the last decade of reform as theatrical. The progress is genuine — partial, incomplete, but real.

The OECD’s Common Reporting Standard, now operating across more than 100 jurisdictions, has transformed the baseline of financial transparency. Nearly 100 countries are now automatically exchanging information on accounts worth $11 trillion — a scale of data-sharing that was unimaginable before 2013. Tax authorities in France, Germany, Australia, and elsewhere have used that data to collect billions in previously unpaid taxes. Several classic bank-secrecy jurisdictions — Switzerland chief among them — have fundamentally altered their operating models. Tax Justice Network

Pascal Saint-Amans, the former director of the OECD’s tax policy division who ran much of the reform programme, has argued that the normative shift matters as much as the technical one. Before 2009, he observed, jurisdictions openly defended secrecy as a legitimate policy. Nobody defends it in those terms today.

Still, critics are right to push back on triumphalism. The Tax Justice Network estimates offshore wealth at between $24 trillion and $36 trillion when a broader range of asset classes is included, dwarfing the OECD’s narrower figure. The gap between information exchange agreements signed and enforcement action taken remains wide. And the beneficial ownership registers that do exist are frequently incomplete, filed with inaccuracies, or practically inaccessible to the investigators who most need them.

The offshore finance industry did not survive a decade of unprecedented regulatory pressure by being fragile.

Closing

The central tension in offshore finance is not between the havens and the reformers. It is between the pace of legal architecture and the velocity of capital. Regulations are drafted, debated, passed, implemented, and tested — a process that takes years. Capital moves in seconds, guided by lawyers and advisers who have read every proposed amendment before it becomes law, and who have already begun stress-testing the structures that will operate within the new rules the moment they take effect.

The crackdowns are real. So is the $13 trillion. The offshore world isn’t thriving in spite of transparency reforms — it’s thriving, in significant part, because of them. Every new compliance framework creates a premium for jurisdictions that can credibly offer both legitimacy and discretion. The more the rules tighten, the more valuable expert navigation of those rules becomes.

Opacity used to be free. Now it’s expensive, sophisticated, and dressed in a compliance report.
