Dialect as trust capital and the other national languages

Züritüütsch in private banking

Private banking is a business of trust, and trust is built in conversation. The Zurich private banks and the wealth management divisions of the large banks serve an international clientele in English, German, French, Italian, Spanish, Russian, Arabic and Chinese, yet their domestic business with Swiss clients is conducted largely in dialect. For a Swiss entrepreneur, a farmer who has sold land to a developer or a family from the Zurich Gold Coast, the relationship manager who speaks the local dialect belongs to the same world. The dialect signals shared schooling, shared military service in the militia army, shared political references and a shared understanding of discretion. Although none of this appears in any contract, it determines which bank receives the mandate and how long the relationship lasts. Economic sociology describes such shared codes as social capital: resources embedded in networks of relationships that lower the costs of cooperation because the parties can rely on common expectations.¹ In Zurich, the dialect is one of the most effective carriers of such capital.

The same mechanism works in the relationship between Swiss banks and their German-speaking clients from abroad. A German client who comes to Zurich expects to be served in Standard German, and Zurich relationship managers switch without difficulty. Their Standard German carries a Swiss accent and Swiss vocabulary, which many German clients perceive as a mark of solidity and discretion. The slight foreignness of Swiss German is part of the product. It reminds the client that the assets are held in another country with another legal system and another political tradition. Germans who work as relationship managers in Zurich often serve German clients in their own variety of the language, while Swiss colleagues serve the Swiss clientele in dialect. Although the division is fluid, it reflects a real difference in the expectations of the two groups. For Austrian clients a further nuance applies, since Austrian German and Swiss German share certain southern features that distinguish both from the German of northern Germany.

The dialect can also become a barrier. A Zurich bank that recruits relationship managers from Germany, the United Kingdom or Asia gains market knowledge and language skills but may lose the ability to serve the local clientele in the way it expects. Swiss clients sometimes perceive a Standard German-speaking adviser as a representative of a foreign institution, even when the bank is Swiss. The larger banks manage this tension by assigning dialect-speaking advisers to the domestic market and international advisers to the cross-border business. Smaller private banks and independent asset managers, which often serve a mixed clientele, need staff who can move between dialect, Standard German and English within a single day. The ability to do so has become one of the most valued skills in the Zurich wealth management labour market.

French and Italian in Zurich

French and Italian occupy a special place in the linguistic infrastructure of Zurich. They are national and official languages, and knowledge of them is expected of senior figures in the federal administration, in national associations and in the boards of large Swiss companies. In the city of Zurich, 6.1 per cent of residents aged fifteen and over named Italian and 4.8 per cent French as a main language in 2019 to 2021, figures that include many immigrants from Italy and France as well as Swiss from the other language regions.² Italian has a long history in Zurich, which received large numbers of Italian workers from the late nineteenth century and again after the Second World War. The Italian community remains the second largest foreign group in the canton after the Germans, as the migration statistics show.³

For the financial centre, French is the language of the Geneva and Lausanne markets, of the western Swiss clientele and of a large part of the Federal Supreme Court’s case law. A Zurich lawyer who litigates before the Federal Supreme Court or who advises on a transaction with a Geneva counterparty must be able to read and write French. Italian is the language of Ticino and of the Lugano financial centre, which serves a large Italian clientele. Zurich banks that serve Italian clients, and the Zurich subsidiaries of Italian banks, work in Italian. The national languages thus form a second layer of multilingualism beneath English. They connect Zurich with the other Swiss financial centres and with the neighbouring markets of France and Italy. The result is an internal diversity that neither Frankfurt nor London possesses.

The school system sustains this diversity, although with growing difficulty. The question of whether primary schools should teach a second national language or English as the first foreign language has divided the German-speaking cantons for two decades. Zurich began testing English from the first primary class in 1998 and was among the cantons that chose English as the first foreign language around 1999 and 2000, which drew criticism from other cantonal education directors. In March 2004 its education council decided to teach English from the second class from 2006/07. In the same month the Swiss Conference of Cantonal Ministers of Education agreed that from 2012/13 a first foreign language would be taught from the third class and a second from the fifth.⁴ The debate illustrates the tension between the two functions of language: English as the language of the global economy and French as the language of national cohesion. The financial centre needs both, and the research of Grin and his colleagues suggests that they are complements in economic terms.
