Abstract
The Swiss private banking sector has, in the past two decades, overcome a major change in its business environment
that reduced the number of Swiss private banks to less than half of what it was in 2008. We focus in this report
on the private banks that survived the turbulence and how they have continued to develop their business operations
after that. Due to the introduction of the Automatic Exchange of Information (AEOI) on January 1, 2017, the banks
had to reassess both the geographies in which they operate and the product/service offerings that they provide for
their clients.
By focusing on the geographic and product/service diversification strategies of the Swiss private banks, we find that
the currently highest performing Swiss private banks are those that successfully expanded their geographic footprint
while at the same time broadening their product/service offerings to address the intensifying competition. The dual
diversification strategy allowed the Swiss private banks to sustain both growth and profitability. They built scale by
establishing a presence in multiple markets worldwide while simultaneously evolving their product offerings to meet
diverse client needs–all the while maintaining operational efficiency. Our findings also show, however, that diversi fication is not a universal remedy. Private banks that did not expand geographically, but still chose to offer a broad
array of products/services, have underperformed both the more diversified and the more focused banks. At the same
time, boutique banks with a concentrated domestic presence and a narrower set of core offerings managed to retain
strong profitability.
The strategic context of 2025, with increasing global geopolitical uncertainty, amplifies the significance of these find ings. Clients are increasingly valuing regional presence alongside digital access, sustainable investment options,
and a broader range of wealth management services that go beyond traditional asset management. The banks that
have their diversification efforts aligned with these broader trends are better positioned to address these demands.
For example, those that moved early into growth markets like the Middle East or into new investment themes like
ESG investing or Cryptocurrencies are now reaping the benefits of being ahead of the curve. In contrast, banks that
have stood still have found themselves vulnerable to these changes.
In summary, we find that diversification has proven to be a double-edged sword for Swiss private banks over the past
decade. Expanding internationally and enlarging service offerings has clearly enabled scale and revenue growth
for proactive Swiss private banks, helping them capture emerging opportunities and spread risk across markets. Yet,
diversification without strategic clarity or sufficient scale would seem to have led to lower profitability. It would seem
that in order to prosper in the current climate, Swiss private banks must either commit to achieving the scale and
breadth needed to compete globally or choose a focused boutique strategy where they can be best-in-class in customer
intimacy. Striking the right balance – growing and innovating, but with prudent limits – will be critical as the industry
continues to adapt to the post-2025 landscape of global wealth management.
