UBS has reduced interest rates for its staff, including retirees, with private account interest dropping from 0.3% to 0.15%. Additionally, the margin on variable-rate mortgages will increase from 35 to 45 basis points, reflecting a significant tightening of conditions amid anticipated cuts to the Swiss National Bank's key interest rate. Insiders suggest these changes were communicated informally, as the bank faces scrutiny over its pricing strategies amidst a challenging economic environment.
