Every serious ranking of global financial secrecy tells the same inconvenient story: the world's biggest enablers of tax avoidance and financial opacity are not small tropical islands. They are the United States, Switzerland, Singapore, Luxembourg and the United Kingdom's own financial network. On the Tax Justice Network's Financial Secrecy Index, these are consistently among the five biggest suppliers of financial secrecy on Earth. Mauritius, by contrast, sits far down the list — around the 54th spot globally, well behind Egypt, Nigeria and Kenya, let alone the traditional secrecy giants.
And yet it is Mauritius that has spent the last several years fighting to shed the "tax haven" label — lobbying the EU, negotiating with the FATF, and rebranding itself at every opportunity as an "international financial centre." Switzerland and Luxembourg, meanwhile, have worn the label for decades with something close to indifference. London barely bothers to argue.
This is not a story about who is more guilty. It is a story about who gets to write the rules — and who has to live by them.
The numbers don't support the reputation
By the technical measures researchers actually use — effective corporate tax rates, banking secrecy, beneficial ownership opacity, treaty shopping facilitation — Mauritius is not meaningfully worse than the jurisdictions that face far less scrutiny. If anything, the index data suggests the opposite: Luxembourg and Switzerland have ranked among the world's very top secrecy jurisdictions for years, described by researchers as jurisdictions that "sell secrecy services at scale" rather than places accidentally caught up in wrongdoing. The UK's own offshore network — the City of London plus Jersey, the Cayman Islands and the British Virgin Islands — has repeatedly topped the same rankings.
Mauritius was formally grey-listed by the EU between 2019 and 2021 and flagged by the FATF over anti-money-laundering gaps. It fought hard, made reforms, and was eventually removed from both lists. Switzerland and Luxembourg have never faced comparable blacklisting, despite scoring as high or higher on secrecy metrics throughout.
Why the discomfort is so unevenly distributed
Who writes the rules, and who gets judged by them. The EU, OECD and FATF are the bodies that produce the blacklists — and they are dominated by the very countries whose financial sectors would qualify for those same lists. Luxembourg is an EU member state; it is never going to blacklist itself. The UK helped design the modern anti-money-laundering architecture. Mauritius, by contrast, is a rule-taker. It gets evaluated by a system it had no hand in building.
A double standard with an uncomfortable undertone. Researchers who study these rankings have pointed out something worth saying plainly: Global North financial centres tend to get gentler language — "competitive tax regime," "wealth management hub," "financial centre" — while smaller, often non-white-majority jurisdictions doing structurally similar things get "tax haven" and "high-risk jurisdiction." The practices are comparable. The vocabulary, and the consequences, are not.
Economic dependency changes the stakes. Switzerland and Luxembourg have deep, diversified economies where financial services is one pillar among several, backed by strong currencies and, in Luxembourg's case, full EU market access. For Mauritius, offshore finance is a much larger share of GDP and state revenue. A blacklisting is an inconvenience for Zurich. It is closer to an economic emergency for Port Louis.
Historical inertia protects the incumbents. Swiss banking secrecy and Luxembourg's holding-company regime predate the modern scrutiny regime by decades. By the time the FATF, the EU and the post-2008 G20 crackdowns arrived, these jurisdictions were already too embedded in global finance to sideline without disrupting the system itself. Mauritius built its offshore sector mainly from the 1990s onward — late enough to be judged by a rulebook the older players never had to answer to when they were establishing themselves.
The India factor. Mauritius's offshore model was built substantially around treaty-based investment routing into India, formalised through a double taxation avoidance agreement. India has periodically renegotiated or threatened to renegotiate that treaty specifically because of "treaty shopping" concerns — a pressure Switzerland and Luxembourg, with more diversified and less dependency-exposed client bases, simply don't face in the same way.
Two things can be true at once
The Mauritian offshore sector's objection to the "tax haven" label is not baseless. The double standard is real, measurable, and documented by the same indices that would justify the label in the first place. Mauritius is being judged more harshly than jurisdictions that objectively do more to enable global financial secrecy.
But that does not make Mauritius innocent of the underlying practice. Resisting the label also serves to protect the very structures — low-tax treaty routing, limited beneficial-ownership transparency, an economy heavily reliant on offshore capital — that invited the label in the first place. The uncomfortable truth is not that Mauritius is falsely accused. It's that everyone named in this article is running some version of the same playbook. The only difference is who is powerful enough to have the label not stick.
