The Caisse de garantie et d'amortissement (literally the Guarantees and Amortization Fund) was a French financial institution set up by the French Consulate in 1800 to spread the national debt. Re-formed several times between 1804 and 1811, it was finally liquidated in 1816 and replaced by the Caisse des dépôts et consignations.
