For more than a century, Switzerland was synonymous with financial discretion. The Swiss Banking Act of 1934, which criminalised the disclosure of client information by bank employees, created a legal fortress around depositor privacy that attracted capital from every corner of the globe. At its peak, Swiss banks managed an estimated $7.9 trillion in cross-border assets, accounting for roughly a quarter of all offshore wealth worldwide.

Today, that fortress has been breached — but the reality of what changed, and what did not, is more nuanced than most commentary suggests.

The dismantling: 2008 to 2018

The beginning of the end can be traced to February 2009, when UBS agreed to pay $780 million in penalties and hand over the names of 4,450 American account holders to the US Department of Justice. The case shattered the assumption that Swiss banking secrecy could withstand determined enforcement by a major sovereign power. What followed was a decade of systematic erosion. In 2009, Switzerland agreed to adopt the OECD standard on exchange of information upon request, effectively ending its refusal to cooperate with foreign tax investigations.

In 2013, the Swiss parliament approved FATCA compliance legislation, requiring Swiss banks to report accounts held by US persons to the IRS. In 2014, Switzerland committed to the OECD’s Common Reporting Standard, joining the automatic exchange of financial information with over 100 jurisdictions. The first CRS exchanges involving Switzerland took place in 2018. The scale of the transition was enormous.

Between 2013 and 2018, Swiss banks processed an estimated 15,000 voluntary disclosures by foreign clients who chose to regularise their tax affairs before the automatic exchange made concealment impractical. Billions in assets were repatriated to clients’ home countries. Several smaller private banks, whose business models depended heavily on non-compliant foreign money, closed their doors permanently.

By 2020, the OECD’s Global Forum on Transparency and Exchange of Information rated Switzerland as "largely compliant" with international standards — a designation that would have been unthinkable a decade earlier. The legal infrastructure of Swiss banking secrecy had been dismantled, at least as it applied to foreign tax authorities.

What actually survived

And yet, Switzerland remains one of the world’s leading centres for international wealth management. The Swiss Bankers Association reported total assets under management of approximately CHF 8.1 trillion in 2022. If banking secrecy was the sole driver of Switzerland’s appeal, the industry should have collapsed. It did not. The reason is that Switzerland’s competitive advantages extend far beyond secrecy.

The Swiss legal system provides some of the strongest creditor protection and trust law frameworks in continental Europe. The Swiss franc is one of the world’s most stable currencies, backed by the Swiss National Bank’s conservative monetary policy and the country’s persistent current account surpluses. Swiss banks are among the best capitalised in the world, with Credit Suisse’s 2023 absorption by UBS being the notable exception rather than the rule.

Switzerland’s political stability is another factor that no regulatory change can diminish. For clients from jurisdictions with political risk — whether in Latin America, the Middle East, or parts of Asia — the Swiss combination of direct democracy, federal governance, and strict rule of law provides a level of institutional security that few other countries can match. The professional ecosystem surrounding Swiss banking is equally important.

Geneva and Zurich host concentrations of tax advisors, trust companies, family offices, and independent asset managers that rival any financial centre in the world. This ecosystem provides services — estate planning, philanthropy coordination, multi-generational wealth structuring — that are independent of banking secrecy and that continue to attract sophisticated international clients.

The privacy that remains

It is also important to understand what Swiss privacy law still protects. The automatic exchange under CRS applies to financial accounts — bank accounts, custody accounts, insurance contracts with a cash value. It does not apply to real estate holdings, art collections, tangible assets stored in freeport facilities, or corporate structures that do not themselves hold reportable financial accounts. Swiss domestic privacy protections remain robust.

Article 13 of the Swiss Federal Constitution guarantees the right to privacy, and the Federal Act on Data Protection (FADP), revised in 2023, strengthens protections for personal data held by both public and private entities. While these protections do not override international tax reporting obligations, they do provide a legal framework that limits the circumstances under which personal financial information can be disclosed beyond what is required by treaty.

Furthermore, CRS has significant limitations. It reports account balances and income on an annual snapshot basis. It does not provide real-time transaction monitoring. It does not capture the purpose of transactions or the economic substance behind account movements. A CRS report tells a foreign tax authority that an individual has an account with a certain balance in Switzerland. It does not tell them why that account exists, what it is used for, or how it fits into the individual’s broader financial architecture.

The redistribution of offshore wealth

The decline of Swiss banking secrecy did not eliminate the demand for international asset holding. It redistributed it. Assets that left Switzerland in the post-FATCA, post-CRS era did not simply return to their countries of origin. Many migrated to jurisdictions that offered the combination of stability and discretion that Switzerland had historically provided — but under a different regulatory framework.

The United States emerged as a primary beneficiary. As we analysed in our February 2024 article, the US combination of non-participation in CRS, strong domestic legal protections, and the depth of the dollar banking system made it an increasingly attractive destination for international capital. Singapore, which adopted CRS but offered its own combination of political stability, legal sophistication, and proximity to Asian growth markets, attracted another significant portion.

Dubai, with its zero-tax environment and rapidly developing financial infrastructure, captured a further share. The lesson for international structuring professionals is clear. The question is no longer "where can I hide assets?" It is "where can I hold assets in a way that is legally robust, institutionally credible, operationally functional, and compliant with my reporting obligations?" The jurisdictions that answer that question most effectively — regardless of their secrecy characteristics — are the ones that will capture the next generation of international capital.

Implications for international entrepreneurs

For the clients we serve at Fidelys Partners, the evolution of Swiss banking secrecy is not an abstract policy story. It is a practical reality that shapes how and where structures are built. Switzerland remains a viable and attractive jurisdiction for certain purposes — custody of assets, insurance wrappers, certain trust structures, and private banking relationships. But it is no longer a jurisdiction where privacy alone is a reason to place assets.

The modern approach to international structuring requires a clear-eyed assessment of each jurisdiction’s actual characteristics: its legal framework, its tax treaty network, its banking infrastructure, its reporting obligations under CRS and FATCA, its political stability, and its institutional quality. Privacy is one variable among many. In a post-CRS world, it is rarely the decisive one. At Fidelys Partners, we design structures that are built for the regulatory environment as it exists today — not as it existed a decade ago.

The era of secrecy- dependent structuring is over. The era of substance-dependent structuring has arrived.
