The year-on-year decline in the Syntec Index in August 2026 is an unusual development. It does not necessarily mean that individual salaries have fallen overall. The index is based on payroll costs and workforce levels from a panel of companies, using a 12-month rolling calculation. This change should therefore be interpreted with caution.
