Ansbacher was founded in the City of London in 1894. In the flourishing international banking environment that existed in the City at the turn of the 20th Century the company grew rapidly. By 1930, Henry Ansbacher & Co Limited was the largest trader of US securities in London and one of the United Kingdom’s largest stockbrokers.

By the 1980’s, activities had expanded into offshore banking and fiduciary operations, enhanced by the acquisition of interests in the Caribbean. Ansbacher then expanded further into the Channel Islands and Europe.

In 2004, Qatar National Bank (QNB) concluded an agreement for the purchase of Ansbacher. Founded in 1964, QNB is the largest and longest established commercial bank in Qatar. Listed on the Doha Stock Exchange, ownership of QNB is split between the government of Qatar and private sector shareholders. QNB is the principal banker to the Qatari government.
