PortWatch
IMF PortWatch adds a maritime monitoring layer to the broader A1AYN data stack. The current snapshot focuses on strategic chokepoints, reference layers, and daily transit activity that can support trade-risk interpretation and logistics monitoring.
Daily chokepoint transit
Daily transit calls and estimated trade volumes across major chokepoints.
Chokepoints reference
Static reference layer for strategic maritime bottlenecks.
Ports reference
Wider port reference layer for context, mapping, and infrastructure overview.
Why this matters
PortWatch is useful as an infrastructure and logistics signal layer. It does not replace vessel-level commercial tracking tools, but it is valuable for monitoring chokepoints, transit intensity, and broader maritime pressure points that can affect trade flows and supply-chain resilience.
