The Communists took over Shanghai in 1949. HSBC continued to operate in the relative freedom of the early years of the People's Republic. However, in 1955 the political situation led the bank to scale down its operations in Shanghai. The building was handed over to the government, and HSBC rented separate offices nearby. Later in that year, the Shanghai Municipal Government moved into the building. The building's name was changed to "The People's Government of the Municipality of Shanghai Building", or "Municipal Government Building" for short. The subsidiary building housed the Municipal Archives from 1956.
