In 1964 it was decided to separate the Banking Services from the Worms & Cie partnership. Banque Worms & Cie was launched on 31 December 1964. Worms & Cie was now purely a holding company, owning three independent companies involved in ship building, maritime and coal services, and banking. In September 1965, an agency named Permal International Inc. was established in New York. In June 1966, Worms & Cie signed a cooperation agreement with
Paribas that lead to the Paribas subsidiary Banque Foncière du Maroc and the Banque Ottomane Maroc concentrating their banking activities with Worms & Cie (Maroc). A cooperation agreement was signed with
Crédit du Nord in December 1966. On 30 March 1967, the Banque Worms & Cie general partnership become Banque Worms SA, a public limited liability company with Raymond Meynial as chairman and Robert Dubost as general manager. In April 1970,
Crédit du Nord and Banque Worms took cross-shareholdings. Louis de Fouchier, president of Crédit du Nord, sat on the board of Banque Worms and Robert Dubost sat on the board of the Crédit du Nord. On 17 April 1967, the
Bank of London and South America (BOLSA) and the
Bank of Scotland acquired a 10% stake in Banque Worms. Meynial arranged to merge Sofibanque-Hoskier and the Banque Industrielle de Financement et de Crédit (BIFC) with Banque Worms effective retroactively to 1 January 1967. Capital was increased and new shares were purchased by Bolsa, Bank of Scotland, and the
Hessische Landesbank Girozentrale. Banque Worms now had agencies in Marseilles, Lyon, Lille,
Le Havre,
Montpellier,
Nice and
Toulouse. A subsidiary, Société Méditerranéenne de Banque, was located in
Ajaccio and
Bastia. The North African subsidiary, Worms and Cie-Maroc, joined forces with the Banque industrielle de l'Algérie et de la Méditerranée (BIAM) in
Algiers and the Banque d'Escompte et de Crédit à L'industrie (BECI) in
Tunis. The
Philadelphia National Bank acquired just over 7% of the capital of Banque Worms as of 27 June 1968. Reciprocal arrangements were made with Crédit Industriel et Commerce and its entire group,
Crédit Commercial de France, Crédit du Nord and the
Banque de l'Union Parisienne allowing Banque Worms customers to make withdrawals from branches of these banks across France. Banque Worms continued to make investments in areas such as real estate finance, canning, oil transport and petrochemicals. In April 1969, the bank established a subsidiary in
Geneva, Switzerland, named Banque Worms et Associés (Genève) SA. On 15 December 1970, the bank's shares were floated on the
