Standing assessment
Current condition
Moderate confidenceAs of
No Joint War Committee listing of Taiwanese waters has been recorded, in 2022 or since; hull war-risk cover for Taiwan-bound voyages remains on standard terms.
Commercial traffic went around the announced closure areas in August 2022 within days of the announcement, on the announcement rather than on any verified risk, and the same behaviour is the documented response to each exercise since.
Latest reviewBaseline
Opened with the module's standing watch list at the Taiwan convergence pass of 28 August 2026, which separated rerouting from repricing and named the listing as the binary.
Why it matters
Two distinct behaviours, previously run together. Rerouting costs days and is reversible. Insurance repricing is slower, threshold-driven and shows what the market believes: the Joint War Committee's Listed Areas determine where hull war-risk cover must be individually negotiated, and it did not list Taiwanese waters during the 2022 crisis. The Red Sea shows what a listing does when one comes — rates moved from about 0.05 per cent of hull value to 0.5–1.0 per cent per voyage after December 2023 and transits fell sharply. That is precedent for the mechanism, not a figure transferable to Taiwan.
Why continued absence matters
The absence of a listing through the Justice Mission exercises and the record coast guard presence of 2026 is the market's own reading of the threshold, and it is recorded each review because a listing is the one commercial event that cannot be reversed by the next week's announcement.
Observables5 named · “met” describes evidence, not success
01Test
A Joint War Committee listing of Taiwanese waters
The clean binary. Any listing of the strait, the eastern approaches or the main ports as a Listed Area.
03Test
Rerouting around announced closure areas
Whether traffic diverts on the announcement, and for how long after the window closes. Fast rerouting is the established pattern; persistence past the window is the change.
04Test
Port arrivals at Kaohsiung and Keelung against the prior month
Published arrivals, read monthly, so a diversion that becomes a decline is visible as one.
05Test
Charterparty war-risk clauses naming Taiwan
Reported changes to standard clauses — a listing's commercial shadow, and sometimes ahead of it.
What would change the assessment2 thresholds · the boundaries as the record states them, none with a number
A Joint War Committee listing, or two consecutive months of quoted premiums on Taiwan-bound voyages above standard terms
Would meanmoves the market from rerouting to repricing.
A named exercise producing no rerouting at all
Would meanshows the market treating announcements as routine.
What remains unknown
- No pre-crisis premium series for Taiwan-bound voyages is published, so no multiple or percentage increase is calculated here.
- Rerouting is documented by AIS analysis and shipping reporting rather than by an official series.
Readings the evidence also supports
- The market prices Taiwan risk through charterparty clauses and freight rates rather than through the Committee's list, in which case the listing is a lagging rather than a leading marker.
Listed because the record's own assessment is not the only one its sources permit — not as a hedge on the assessment above.
