Hambros Bank was a British bank based in London. It was a specialist in Anglo-Scandinavian business with expertise in trade finance and investment banking, and was the sole banker to the Scandinavian countries for many years. Hambros Bank was sold in 1998, and today survives only in the name of the private banking division of the French group Société Générale, which is called SG Hambros Bank.
Hambros was founded by the Danish merchant and banker Carl Joachim Hambro in London in 1839 as C.J. Hammbo & Son.
After merging with the British Bank of Northern Commerce in 1921 the name was changed to Hambros Bank, and the firm expanded.
After the Second World War, Hambros became known as the “diamond bank” with its thriving activity in financing the diamond industry and its trade. The 1970s marked Hambros expansion into new areas of financial services, such as asset management, investment funds and insurance.
In 1998 Hambros Bank was acquired by Société Générale.
