Swiss foundations’ assets grow by 24% in five years

The total assets of some of Switzerland’s leading foundations grew by 7.2% in 2025, which is a slight drop on 2024’s 8.1%.

This is according to new research by SwissFoundations based on data from 55 foundations with total assets of 15.1bn CHF (€16.1bn). They range from very large foundations with more than 250m CHF in assets, to others with less than 10m CHF.

The average cumulative return since 2021 is 23.9%.

Average five-year returns were even higher – an average of 29.6% – for foundations holding more than half of their assets in equities (i.e. shares).

The average foundation holds 49% of their assets in equities, with the rest in bonds (20%), real estate (16%), cash (5%) and other asset classes.

The larger foundations in the study generally had more assets in real estate and less than average in equities. Smaller foundations tended to have more in bonds, and more than twice as much (10%) in cash.

Some sustainable investments

While 80% of the organisations in the report said they included sustainability in their investment decision making, the majority of their assets were not held in sustainable funds. Of those using sustainable investments, 37% said less than 10% were in sustainable assets, and 36% between 11% and 25%.

The most common sustainability approach (used by 89%) of the sample was exclusion criteria for certain undesirable industries, followed by positive criteria (used by 73%).

Among the 11 organisations that didn’t apply sustainability criteria, the most commonly cited reasons were: concerns that it wasn’t suited to achieving their foundation purpose; lack of clarity around the issue; and concerns about a reduced financial return.
