In 1908 the French state entrusted it with the management of its housing loans and the French law of 26 February 1921 authorised loans on savings funds for low-cost housing (HBM), prefiguring the first social housing (HLM). The French law of 1928, known as “Loi Loucheur”, did not change this mission, rather it strengthened Caisse des Dépôts’ role through a programme of unprecedented scale: 200,000 low-cost homes and 80,000 average rent homes.
This role of funding social housing was strengthened after the Second World War by the implementation of different regulated saving centralisation systems. Caisse des Dépôts is now a key stakeholder in social housing, also contributing to other policies in the general interest: funding of urban affairs, transport infrastructure, etc.
It is also a stakeholder in intermediary housing, a missing link designed for households which have incomes over the HLM ceiling amount, without necessarily being able to get accommodation on the free market.
