Climate change, demographic winter and the search for sustainability affect the growth in the dynamics of cities. There is a constant, historical, entrepreneurial and anthropological connection between bank and city. In Italy the flight from the cities continues, but urbanization is advancing. Big cities change their skin and look forward, with the prospects of smart cities and green aspirations, of urban forests and areas to lower the pressure of the great heat. Villages in some cases gain space, in others they lose residents and entrepreneurial activities, medical and security devices. Banks follow the flow of what is happening. For ABI President Patuelli «the Special Economic Zone must be expanded to depopulated areas in the Apennines and Alps. Depopulation is a reality, but the banks leave for last».
