Caisse des Retraites du Sénat

Caisse des Retraites du Sénat

The Caisse des Retraites du Sénat was established in 1905 to administer the retirement benefits of France's Senators. It is an autonomous legal entity, governed entirely within the Senate under the authority of the three Questeurs, who are responsible for the upper chamber's administrative and financial management. The fund receives no financial support from the French State or other public social-protection schemes; its resources come solely from Senatorial contributions, employer contributions paid by the Senate, and investment income. Asset management is split between a directly held real-estate portfolio concentrated in Paris's 5th, 6th, and 7th arrondissements and a diversified financial-reserve book. The property holdings include the Palais du Luxembourg itself, the Petit Luxembourg, the Musée du Luxembourg, and a collection of mixed-use residential and office buildings on Rue Bonaparte and Rue Garancière. The fund's investment strategy extends to private equity and venture capital, covering early-stage, expansion-stage, and late-stage commitments, typically accessed through fund structures and co-investments rather than direct majority deals. The Caisse des Dépôts et Consignations frequently appears as a co-investor and service provider on French public-pension mandates. The fund does not publish its total assets. Altss estimates AUM of roughly $2.1 billion based on the scale of its Parisian real-estate footprint and financial-reserve disclosures. The Caisse participates actively in the Association française des investisseurs institutionnels (Af2i), with its team contributing to ESG and investment-strategy working groups. As of mid-2026, the Senate continues to operate under the presidency of Gérard Larcher, whose administration oversees the fund's governance. The Caisse's structural distinction is its total institutional isolation: it is a pension scheme for a single constitutional body, funded exclusively by that body and its members, and managed inside the same building where the legislature sits. Other public schemes rely on demographic pooling or state guarantees; this one runs on Senate contributions and the rent rolls of a few dozen buildings within walking distance of the hemicycle.
