The Imperial Bank of Persia (Persian: بانک شاهنشاهی ایران, romanized: Bânk-e Šâhanšâhi-ye Irân), sometimes transcribed as Bank Shahi, was a British bank that played a central role in the financial history of late Qajar Iran, known in English at the time as Persia. The bank was legally established in London and subject to British law, with the bulk of its operations based in Tehran under a concession initially granted by the Qajar government to Paul Julius Reuter. It served as the country's main bank of issue until that role was transferred to Bank Melli Iran in 1932, and introduced European financial practices to a country in which they were previously unknown.
Following political changes in Pahlavi Iran it was renamed the Imperial Bank of Iran in 1935, then the British Bank of Iran and the Middle East in 1949 following expansion into other Middle Eastern countries. In 1952, its operations in Iran were terminated, with some of its former business restructured as Bank Bazargani. The remaining activity outside Iran was renamed British Bank of the Middle East (BBME), which in 1959 was purchased by HSBC and in 1999 was renamed HSBC Bank Middle East. Bank Bazargani in turn was reorganized in 1979 following the Iranian Revolution, to become the nucleus of Bank Tejarat.
