Indexed rent

In Swiss tenancy practice, an indexed rent clause ties rent changes to the movement of a recognised consumer price index. It is mainly used for leases of a certain minimum duration and must be agreed clearly. The clause does not allow arbitrary increases: adjustments follow the index and any contractual or legal limits. Tenants should distinguish indexed rent from changes based on the reference interest rate, cost increases or market comparisons. Formal notice requirements may still apply to rent increases.
