Since the early 2000s, financial operators have been increasingly stimulated to seek new clients and additional investment opportunities in port infrastructures. Initially, they emerged as key players orchestrating big financial deals in the sector. Later on, they also became active investors in ports and related infrastructures. This chapter aims at identifying the intrinsic characteristics, objectives and global strategies of various types of financial operators, including investment banks, private equity funds, sovereign wealth funds and state-owned enterprises, pension funds and insurance companies, and investment holding companies, as well as multilateral financial institutions and development banks. In particular, by scrutinizing their strategic objectives and related implementation mechanisms, we focus on the temporal and spatial breakdown of their investments in cargo terminals and ports.
