The Mengjiang Bank, also Meng Chiang Bank or Bank of Inner Mongolia (Chinese: 蒙疆銀行), was a central bank of the Japan-supported government of Mengjiang that governed Inner Mongolia during early years of the Second Sino-Japanese War, from late 1937 to early 1941.
It was thus one of the "puppet" banks of issue established by the Japanese occupation forces, together with the Central Bank of Manchou (1932-1945), United Reserve Bank (1938-1945), Huaxing Commercial Bank (1938-1941) and Central Reserve Bank (1941-1945).[1]: 6
