The Ottoman Bank opened a branch in Beirut immediately after its creation in 1856. It was reorganized in 1863 as the Imperial Ottoman Bank, known by its French acronym BIO for Banque Impériale Ottomane. In the 1890s, the BIO was instrumental in developing the Port of Beirut and the Beirut-Damascus railway and extensions in Syria.[2] The branch was initially located inside Khan Antoun Bey in the Beirut Souks; in 1892 it moved to a new building on place des canons, now Martyrs' Square; and in 1906 to another new building in Western architectural style on the waterfront at the northern end of the street later named Allenby Street, while the previous location was repurposed as the Khedivial Hotel.[3] The former two venues were destroyed during the Lebanese Civil War and not rebuilt during postwar reconstruction, while the latter was replaced before the war by the high-rise office building known as One Allenby Street.

Following Ottoman defeat during World War I, the territories of what later became Syria and Lebanon were ruled by the Occupied Enemy Territory Administration that brought together France, the UK and the Hashemites. The French authorities desired to control monetary policy in the territories they administered.

Building at 16, rue Le Peletier in Paris, the bank's head office from 1919 to 1927

In response to this new environment, the BIO decided in late 1918 to form a French bank, initially named Banque de Syrie and headquartered in Paris, in which the BIO initially retained 94.45 percent ownership.[4] The new bank held its constituent general meeting in Paris on 2 January 1919.[5] In March 1920, the French authorities granted the new bank the privilege to issue currency notes. The BIO, by then controlled by the Banque de Paris et des Pays-Bas (BPPB), transferred to the new entity its existing branches in Aleppo, Alexandretta, Beirut, Damascus, Hama, Homs, Sidon, Tripoli and Zahlé, a transaction that was only completed in late 1921.

The formalization in 1923 of France's Mandate for Syria and Lebanon led to the bank's first name change to Banque de Syrie et du Grand-Liban, on 5 March 1924. It eventually adopted the name Banque de Syrie et du Liban on 23 May 1939. It kept operating during World War II despite the breakdown of communication between occupied France and its Levantine mandate territories following the Syria–Lebanon campaign of June–July 1941.[5]

The bank opened new branches in Latakia in the early 1920s, Antioch in 1925, Deir ez-Zor in 1930, and by 1937 also had branches in Aley, Idlib, Qamishli, As-Suwayda, and Tartus. It also had a representation in Marseille at the Ottoman Bank's branch.[6] Its Parisian head office was initially at 16, rue Le Peletier, in a building acquired by the Banque de l'Union Parisienne in 1913,[7]^: 40 and next door to the BIO's older affiliate the Banque Franco-Serbe (est. 1910). It moved on 16 May 1927 to 12, rue Roquépine.[5] In 1939, Türkiye annexed the Hatay State, including Alexandretta (now İskenderun) and Antioch (now Antakya). Later on the BSL also opened branches in Daraa, Al-Hasakah, and Raqqa in Syria, as well as Baalbek and Tyre in Lebanon.[5]

The Lebanese pound was introduced in 1939 as a separate currency from the Syrian pound, following on earlier introduction of Syrian pound notes that included a mention of Lebanon but were interchangeable with other Syrian pound notes.[8] Even so, the two currencies, both issued by the BSL, remained pegged to a reference currency (the French franc until 1941, then the British pound) and thus to each other until in 1948, after the two countries' independence.

In 1953, the Second Syrian Republic authorities withdrew the BSL's issuance privilege of the BSL, which after a three-year transition was taken by the newly established Central Bank of Syria in 1956. Later in 1956, all BSL operations in Syria were nationalized in the aftermath of the Suez Crisis, and taken over by the state-owned Commercial Bank of Syria.[9]

In Lebanon, the country's central bank, the Banque du Liban, was formed in 1963 from the issuance-linked operations of the BSL.[10] The BSL's commercial operations were taken over by a new Lebanese entity controlled by the BPPB, the Société Nouvelle de la Banque de Syrie et du Liban (SNBSL), created on 2 April 1963, and kept operating under that brand for half a century.[11] In the process of separation, the SNBSL secured ownership of the recently constructed BSL head office building on rue Riad El-Solh in downtown Beirut, with financing from the BPPB-controlled Ottoman Bank. The modern building, which had been built in the early 1950s and inaugurated in 1955, hosted both organizations until the inauguration of the Banque du Liban's own new head office in late March 1964.[12][13]

The SNBSL kept operating during the Lebanese Civil War.[11] In 1987, the BPPB, by then known as Paribas, sold its majority stake to Lebanon's El-Khoury family group. Its head office building on rue Riad El-Solh was restored in the 1990s from wartime damage. On 4 July 2012, the SNBSL was rebranded as BSL Bank.[14]
