Swiss pension funds faced a challenging April, with an average loss of 1.01% following a negative return of 1.46% in March. Market volatility was driven by U.S. tariff announcements and concerns over the Federal Reserve's independence, impacting various asset classes negatively. Small pension funds suffered the most, while Swiss franc bonds and real estate showed slight gains. The UBS Chief Investment Office suggests that while uncertainty has peaked, volatility may persist, with optimism for U.S. equities due to easing trade tensions and potential interest rate cuts.
