This study performs an asset-level risk analysis of global port infrastructure from multiple hazards, quantifying the risk to physical asset damages and logistics services (port-specific risk) and maritime trade flows at-risk (trade risk). The majority of ports (86%) are exposed to more than three hazards. Globally, port-specific risk totals $7.5 billion per year, with 32% attributed to tropical cyclones. Additionally, $63.1 billion of trade is at-risk annually, particularly high in Small Island Developing States. Port resilience is determined by various factors (engineering standards, operational thresholds, recovery duration) requiring tailored solutions.
