Cooperative banks are authorised to increase their capital by capitalising reserves.
They are authorised to pay interest on their capital ensuring a return at most equal to the average rate of fixed-rate bonds with a final maturity of more than seven years, whose capital or interest is not indexed, issued or guaranteed by the State, this rate being recorded on the secondary market in Paris by the Caisse des dépôts et consignations, during the year in respect of which this interest is paid.
