Old-age and survivors insurance (OASI, French: AVS German: AHV Tosk Albanian: AHV) constitutes one of the main social security schemes in Switzerland.
The federal law on OASI was passed on December 20, 1946, and approved by popular vote on July 6, 1947, by almost 80% of the votes. It was subsequently harmonized and coordinated with the federal law on disability insurance adopted in 1959. A series of ordinances, the most important being the regulation on old-age and survivors insurance,[1] specifies this.
From the January 1, 1948, date of its entry into force, this legislation underwent numerous modifications. Until 1974, the evolution of the OASI was a fairly accurate reflection of the post-war economic boom. Between 1975 and 2008, the OASI was subject to ten actual revisions and three minor legislative revisions. An 11th revision is under discussion in 2009.
This is a pay-as-you-go pension system, the law on occupational pensions (2nd pillar) being a funded pension system. The OASI also allows for a (partial) redistribution of wealth.[2] According to the Federal Social Insurance Office, the OASI is “the most important branch of the Swiss social insurance system”.[3]
