In association with other prominent bankers and business leaders, the Periers also engaged in the establishment of new financial institutions of the Restoration. Thus in 1818 Casimir and Scipion were among the founder-directors of the first French savings bank, the Caisse d’Épargne et de Prévoyance de Paris (No. 104, rue Richlieu). Besides the Perier bank, other investors included Jacques Laffitte (governor of the Bank of France, 1814–19) and the banks of Lefebvre, Pillet Will, and Cottier. The same five banking houses helped back the organization during 1816-20 of an important early insurance company, the Compagnie Royale d’Assurances, and in 1823 they would take part in the Compagnie des Quatre Canaux, a joint-stock company for loans to the government to improve the canal system in northern France. Perhaps a best example of the Perier bank's involvement in innovative financial ventures during the Restoration was the case of the ill-starred Société Commanditaire de l’Industrie. Conceived in 1825 mainly by Jacques Laffitte, its prospective president, this joint-stock company capitalized at 100 million francs was intended to help remedy the growing need in France for increased investment capital for large-scale projects in areas such as mining, metallurgy, canal construction and land development. It had the support of the "haute banque" and foreign banking houses. Casimir Perier and William Ternaux, France's leading woolens manufacturer, were its prospective vice-presidents. But in the end, unfortunately, the conservative Villèle ministry under Charles X refused to authorize the establishment of the Commanditaire.
