The Imperial Bank of Persia was a British bank that operated as the central bank and bank of issue in Iran (formerly known as Persia until 1935) between 1889 and 1929. It was established in 1885 with a concession from the Persian government to Baron Julius De Reuter banker and businessman and Hadji Ali Akbar Tajer Shirazi.
The bank was the first modern bank in Iran and introduced European banking ideas to a country in which they were previously unknown. The legal centre of the bank was in London and whilst it was subject to British law, its activities were based in Tehran. It also had operations in other Middle Eastern countries. It was later named British Bank of the Middle East (BBME) and is now called HSBC Bank Middle East Limited.
