Liechtenstein fiduciary services and Swiss banks: profitability at a price

Liechtenstein has evolved into an attractive location for domiciliary and fiduciary companies since the 1920s. Although politicians in Switzerland have repeatedly voiced misgivings about this, it has also been a source of profit for the Swiss financial centre. This has resulted in a close, albeit fraught relationship between the two neighbouring states.

The close ties between the neighbouring countries of Switzerland and Liechtenstein are commonly accepted as dating back to the Customs Treaty (ZAV) of 1923, under which the two countries became one economic and customs area. However, that fails to take account of another date in their entangled relationship, which established the basis for many bilateral conflicts. 100 years ago, Liechtenstein began to move away from Austria towards a closer relationship with Switzerland. This led to a revision of the country’s Civil Code that was not fully implemented and culminated in the adoption of the Law on Persons and Companies (Personen- und Gesellschaftsrecht, PGR) on 20 January 1926.
 
The PGR plus the liberal Tax Act of 1923 made Liechtenstein an appealing destination for foreign capital, specifically through domiciliary and fiduciary companies. Domiciliary companies were companies registered in Liechtenstein which did not actually conduct business in the country, whereas fiduciary companies managed other people’s assets. These structures allowed people to hide their assets from the Swiss tax authorities and thus avoid stamp duty, a tax on certain capital and securities transactions – even though, under the Customs Treaty, the Principality had agreed to apply Swiss stamp duty legislation and have the tax collected by the Federal Administration.

The appeal of this business model was enhanced further by a special pathway to acquiring citizenship: the introduction of “financial naturalisation” in 1920 allowed people based outside the country to buy Liechtenstein citizenship. As this did not require them to be resident in the state, newly naturalised citizens were able to manage their money from home via domiciliary companies in Liechtenstein and avoid tax in their countries of origin. The capital of these Liechtenstein nationals residing abroad was managed by domiciliary companies based in the country and invested for the most part in Swiss banks, as the funds involved would have been too much for the Liechtenstein banks to handle and the Swiss financial centre enjoyed a good reputation due to its stability.
 
This led to criticism of Liechtenstein company law by Swiss officialdom, while the economic and financial centre was only too happy to make the most of the situation. Swiss banks deliberately channelled foreign clients to the domiciliary companies, which then invested the funds in the Swiss financial market. This resulted in a symbiotic relationship whereby the Liechtenstein domiciliary companies enabled their clients to save on tax and the Swiss economy profited from foreign investment capital.

Joint research

This text is the result of a collaboration between the Swiss National Museum and the Diplomatic Documents of Switzerland (Dodis) research centre and is based on the author’s Master’s dissertation on the bilateral relations between Switzerland and Liechtenstein. An edited version of the dissertation is available on the open-access publication series “Quaderni di Dodis”.
Swiss embassies and consulates were less enthusiastic about this system. They had been representing Liechtenstein’s interests abroad for free since 1919 and were therefore also in charge of processing the applications for financial naturalisation. By way of example, the envoy to Poland, Minister Hans von Segesser, expressed his misgivings about the practice in 1930, saying “in some circumstances, this could involve having to represent the interests of highly undesirable people”, such as the former Austrian-Hungarian diplomat Gerliczy, who was considered “akin to a renegade and traitor to his country” in his homeland. Nonetheless, the authorities initially declined to intervene, despite fearing the potential adverse publicity.
 
That changed in 1941 when the Federal Council complied with Liechtenstein’s long-held wish for a revision of the Immigration Police Agreement, resulting in all Liechtenstein nationals being entitled to a residence permit for Switzerland. This rapprochement was partly a way for Switzerland to further strengthen its ties with its small neighbour as the Third Reich grew increasingly belligerent. But it was also a quid pro quo arrangement whereby the Federal Council gained the right to veto any application for financial naturalisation.

Financial naturalisation was not restricted to the ultra high net worth category. In 1939, it cost about CHF 42,000, equivalent to about CHF 336,000 in 2025. Naturalisation was generally seen as a vehicle for moving capital and avoiding tax until the early 1930s. The main applicants from 1933 onwards were people from Germany, including many with Jewish roots.
Liechtenstein was eventually forced to discontinue the practice of financial naturalisation during the renewed negotiations of 1948 between the two states on how to manage immigration policing and under growing international pressure. It came to an end with the revision of citizenship law in 1960 amid rising concern over excessive immigration. However, the fiduciary business in the Principality continued to thrive as the number of domiciliary companies kept growing after the war.
 
Two events in the 1970s shook the Swiss financial centre. After the Second World War, the Bretton-Woods system had ensured stable exchange rates through the gold-dollar-standard. The collapse of this system suddenly exposed many currencies, including the Swiss franc, to major exchange rate fluctuations. In 1977, it also emerged that the Credit Suisse subsidiary in Chiasso had invested undeclared Italian capital in a Liechtenstein financial company, thereby hiding the origin of the funds. The Chiasso scandal brought attention back to the scope for misconduct at the Liechtenstein financial centre.

Switzerland exercised pressure on Liechtenstein to conclude an official currency treaty. The Principality had already unilaterally introduced the Swiss franc as its national currency in 1924 without making it official by concluding an agreement with Switzerland. Bern had effectively treated Liechtenstein as part of the Swiss franc zone from then on. Switzerland threatened to withdraw these privileges unless the situation changed. Switzerland made the Currency Treaty contingent on a revision of corporate practice in Liechtenstein, i.e. Liechtenstein could only remain within the Swiss franc zone if its company law were reformed to make it more difficult to circumvent Swiss currency measures. (“La Suisse fit alors clairement savoir aux autorités du Liechtenstein que l'inclusion de la Principauté dans la zone monétaire suisse ne serait possible que dans le cas où une réforme du droit des sociétés liechtensteinois rendrait impossible ou difficile le fait d'éluder les mesures monétaires suisses.”)
 
Liechtenstein reformed its legislation and the Currency Treaty entered into force in 1980. However, the reform made little difference in practice, and the number of holding and domiciliary companies in the country continued to grow unabated between 1980 and 2000. That was because the treaty did not include control mechanisms or banking supervision by the Swiss National Bank.
 
Switzerland had another opportunity to rectify the situation about ten years later. On 6 December 1992, Switzerland opted not to join the European Economic Area (EEA); on 13 December 1992, however, Liechtenstein voted in favour of joining the EEA. This referendum result presented the Federal Administration with “numerous problems of a legal and practical nature”, given that Liechtenstein had wanted to preserve the Customs Treaty of 1923 after joining the EEA.
 
As this involved a lot of extra administration, the Federal Council was to take up “the Swiss demand to amend the duty of due diligence in a future negotiation platform to redefine the rules governing relations between Switzerland and Liechtenstein as a consequence of Liechtenstein’s accession to the EEA”. Nonetheless, the Principality opposed the tighter rules imposed on Swiss banks when handling funds following the Chiasso scandal.

As the Federal Council was very keen to push through a VAT system that included Liechtenstein by 1 January 1995, it agreed to delay negotiations on banking supervision due to time pressure, thereby making a major concession to the Principality. The Department of Finance expressed concern, stating in its submission to the Federal Council: “It is hard to see how the government of the Principality of Liechtenstein cannot accede to the Swiss proposals after the longstanding and good shared experiences with the currency and customs treaties, when we were prepared to find solutions to allow the Principality of Liechtenstein to join the EEA – an event that brings Switzerland nothing but complications”.
 
Liechtenstein thus received a reprieve from the imposition of Swiss banking due diligence requirements. It was not until the Organisation for Economic Co-operation and Development (OECD) started asking questions in 2000 and following the massive scale of tax evasion uncovered in the wake of the 2008 banking crisis that Liechtenstein – again under accumulated external pressure – reformed its banking rules.

The horse trading over the Liechtenstein Law on Persons and Companies is a good example of the two neighbours’ mutual hold on one other. Despite the power asymmetry between one small country and an even smaller one, the symbiotic relationship fashioned by recurring conflicts during the 20th century resulted in new legal ties as the mutual entanglement between the two countries became even more entangled.

Switzerland, the land of banks

Switzerland is one of the world’s leading financial centres – but how did its close association with banking evolve? The exhibition shows how deeply banking is entrenched in Switzerland’s DNA and traces the development of the banking system by displaying an impressive range of items. Jewish moneylenders, Lombardy merchants and, later, urban exchange offices laid the foundation for the modern financial centre. The exhibition goes beyond merely retracing historical developments; it also invites visitors to engage with the land of banks as it is today.
