Also found in: Dictionary, Financial.
a kind of capitalist bank specializing in financing and long-term lending to different sectors of the national economy, mainly industry, transport, and trade. Investment banks have become greatly developed particularly during the era of imperialism. The investment banks create their resources basically by offering their own stocks and bonds in the money market. With the development of state-monopolistic capitalism in a number of capitalist countries (including West Germany, Japan, Italy, and Turkey), state investment banks have been founded that derive their funds or capital from the state budget.
