This introductory article revisits cross-border shadow exchanges in a comparative perspective and reflects on their theoretical implications. It explores the diversities and complexities of shadow operations and critically examines the concept of informality that is commonly used to describe such non-state-sanctioned practices. It further underlines the key role played by checkpoint politics in border governance. Border checkpoints serve both as a state institution in regulating border crossings as well as a political site where material and power exchanges among state and non-state actors are negotiated. Such negotiation of selective passage through state-controlled gateways is often predicated upon the skilful manipulation of time and space by experienced traders and brokers.
