When Supply Chains Go Dark: Risks and Resilience

The London School of Economics explores the critical but under-studied phenomenon of supply chain opacity—situations where visibility and transparency are lost across logistics networks. When supply chains 'go dark,' companies and governments lose real-time insight into inventory, shipment status, and supplier operations, creating cascading vulnerabilities. This research highlights that modern supply chains are heavily dependent on continuous data flows and information symmetry; when these break down due to geopolitical events, natural disasters, cyber incidents, or deliberate circumvention, the operational and financial consequences extend far beyond the immediate disruption. For supply chain professionals, this analysis underscores the strategic importance of building redundancy into information systems and supplier networks.

Organizations relying on a single source of truth for visibility—whether through a primary logistics partner, port authority, or customs system—face asymmetric risk. The research implies that resilience in the 2020s requires not just diversified suppliers and routing options, but also decentralized information architecture and backup tracking mechanisms. Companies should audit their dependency on critical data touchpoints and consider investments in blockchain-based or multi-party information platforms that maintain visibility even when primary systems are compromised. The longer-term implication is that supply chain strategy must now incorporate 'dark scenario' planning.

Rather than assuming continuous connectivity and real-time visibility, leading organizations are building protocols for operating under information constraints. This shift reflects a maturing understanding that supply chain resilience is not purely about physical diversification—it is equally about information redundancy, governance transparency, and the ability to make decisions with incomplete data.
