The article explores connectivity from the prism of multilateral development banks. It recognises that theorising on connectivity is increasing, but as connectivity agency is less addressed, it aims to contribute to discussions on who the agents of connectivity are and how they contribute thereto. By analysing the Asian Development Bank (ADB) and the Asian Infrastructure Bank (AIIB) respectively, the article sets forth a three-dimensional agency: strategic, developmental and financial. This is in line with the multi-layered nature of the banks, which reflects the broader member states and key state interests. Next to their role as banks, they contribute to the understanding of development, in addition to which they represent key shareholder interests. The banks are both to be seen as nodes of connectivity and as active agents in realising connectivity for others.
