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.

如何解讀等級
- 已證實 有來源記錄其已經發生。
- 合理可信的曝險 Vigil評估為很可能的機制；尚無其已經發生的紀錄。
- 未經證實的情境 因為值得觀察而列出。並非斷言。
一個步驟的等級永遠不能高於它所依賴的步驟：結果的確立程度不能高於其原因。這項規則在本網站建置時強制執行，而非以人工套用 — 違反它的鏈會導致建置失敗，而不會被發布。
- 觸發因素
在承載世界商業航運相當比例的水域中進行的例行軍事活動，並伴隨定期宣布的限制
- 受影響的資產、路線或地區已證實
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.

- 營運中斷已證實
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.

- 曝險的產業或商品已證實
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.

- 更廣泛的經濟意義未經證實的情境
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.

曝險的產業與商品
以一般標籤命名，而非受控詞彙，因此這份清單不會與本模組經濟部分已使用的商品名稱產生偏差。
仍然未知的事項
- 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.
證據同樣支持的其他解讀
- 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.
