A large share of world container traffic passes through or near the Taiwan Strait, and commercial shipping reroutes quickly around declared restrictions. The mechanism was observed in August 2022; what a sustained interference would cost is an unconfirmed scenario.
Rédigé pour le travail sur le risque géopolitique et l’exposition économique : il retrace un mécanisme, pas une vue de marché.
Comment lire les degrés

Une étape ne peut jamais recevoir un degré de confiance plus élevé que l’étape dont elle dépend : une conséquence ne peut pas être mieux établie que sa cause. Cette règle est appliquée lors de la construction du site, et non à la main — une chaîne qui l’enfreindrait ferait échouer la construction au lieu d’être publiée.
- Déclencheur
Une activité militaire de routine menée dans des eaux qui portent une part substantielle du transport maritime commercial mondial, avec des restrictions annoncées périodiques
- Actif, itinéraire ou région touchésConfirmé
The waters around Taiwan carry a substantial share of global container traffic, including much of the trade between East Asia and both Europe and North America. Taiwan's own trade is entirely seaborne or airborne. The same corridors carry the undersea cables serving the island. Commercial and military traffic occupy the same water continuously, which is the structural fact this chain rests on.

- Perturbation opérationnelleConfirmé
In August 2022, exercises following the Pelosi visit included announced closure areas around Taiwan. Commercial traffic routed around them within days. No vessel was interfered with and the restrictions were short-lived, but the commercial response was immediate and did not wait for any assessment of whether the risk was real. Coast guard patrolling and inspection around Kinmen since February 2024 has applied a law-enforcement framing to presence in contested waters, without extending to vessels bound for Taiwan's main ports.

The exposed quantities are transit time, freight rates and war-risk insurance premiums, and they do not all move together. Rerouting east of Taiwan or through the southern channels adds days and fuel cost rather than making voyages impossible, which is why disruption here expresses itself as a price rather than as a stoppage; that response is fast and is documented, and in 2022 it followed the announcement rather than any verified risk. Insurance behaves differently. Marine hull war-risk cover reprices when the Joint War Committee — the Lloyd's and London company market body that maintains the Listed Areas — adds a water, at which point standing war clauses trigger cancellation-and-reinstatement mechanics and premiums are negotiated per voyage as a percentage of hull value. That did NOT happen in August 2022: Taiwanese waters were not listed at all, and no listing has been recorded since. So insurance is a threshold instrument rather than a continuously sensitive one, and the threshold has not been crossed. For Taiwan itself there is no rerouting option, because the destination is the island.

- Portée économique plus largeScénario non confirmé
What sustained interference would cost is not documented and Vigil does not assert it. Named as worth watching rather than asserted: the 2022 episode lasted days and involved no interdiction, so it establishes that the commercial response is fast and says nothing reliable about what a longer or more intrusive restriction would do. The firmer observations are narrower — the response is driven by announcements rather than by verified risk, third-party vessels are affected identically to Taiwanese ones so any measure internationalises itself immediately, and Taiwan's own trade has no alternative routing. Vigil publishes no cost, duration or volume estimate for any scenario.

Secteurs et produits exposés
Nommés sous forme de libellés simples plutôt que d’un vocabulaire contrôlé, afin que cette liste ne puisse pas s’écarter des noms de produits de base que la section économie du module utilise déjà.
Ce qui reste inconnu
- Insurance pricing is commercially negotiated and only partially visible in published market data.
- The 2022 episode was short and involved no interdiction, so it does not support inference about sustained interference — which is why the final step is graded as an unconfirmed scenario.
- Vigil publishes no cost, duration or volume estimate for any scenario, and the absence is deliberate.
- Attribution for the cable incidents has not been established in any case.
Lectures que les éléments permettent aussi
- Commercial rerouting during the 2022 exercises can be read as evidence of coercive economic effect, or as routine risk management that would follow any announced restriction anywhere in the world. Both are consistent with the observed behaviour, and the distinction matters for how much the episode tells us.
- Stable freight and insurance conditions in ordinary periods can be read as the market judging the risk low, or as the market not pricing tail risk at all until it is imminent. The two imply very different behaviour at the point of any change.
