Seaborne Trade Nowcast

AIS is complete-observation. When customs authorities publish import statistics 4-8 weeks after the month, we already have the arrivals. This board reads country × segment monthly arriving deadweight as an import-intensity proxy — a relative index, because a downsampled trail can't recover absolute cargo tonnage per hull, but consistent under-counting keeps the trend honest.

Regime = percentile of the country's own last-24m distribution: booming ≥85 · building 60-85 · steady 30-60 · cooling <30. The current UTC month is deliberately dropped from the published head — partial data would tilt every country to "cooling" against full-month baselines.

YoY reads engage as history depth passes 12 months per pair. Refreshed each daily run.
