OASI/DI and the Swiss social security system

Old-age and survivors’ insurance (OASI) and disability insurance (DI), which fall under the remit of the CCO, are an integral part of the Swiss social security system. They are at the heart of the first of the three pillars set out in the Federal Constitution of the Swiss Confederation.

Illness, maternity, accidents, family allowances and unemployment also fall within the areas covered by the Swiss social security system. Shortly after OASI came into force, followed by DI in the middle of the 20th century, Switzerland began to conclude social security agreements with various countries, continually expanding its network to this day.
