China has intensified coast guard patrols, maritime law enforcement claims, and vessel presence east of Taiwan throughout 2026, framing these as routine jurisdiction exercises that analysts view as incremental grey-zone pressure and blockade rehearsals. However, no full quarantine or blockade of shipping has materialized, with activity remaining below the threshold of sustained interdiction. Multiple Trump-Xi summits this year, including an anticipated September meeting and APEC gathering, have coincided with reduced aerial sorties and sustained diplomatic channels that raise escalation costs. Traders assign 96.2% probability to no blockade this year because a major military move would risk direct U.S. involvement, global supply shocks, and economic retaliation while current tactics allow Beijing to normalize presence without crossing into open conflict. Late-year incidents, shifts in U.S. arms policy, or internal Chinese leadership pressures remain the primary variables that could alter the outlook before December 31.

A qualifying blockade is:
- Prevents the normal ingress or egress of foreign commercial traffic to or from Taiwan Island’s main ports or airports by threat or use of force for ≥ 24 hours.
- Covers part or whole of the main island of Taiwan (Formosa).
- Is declared and enforced, de facto (e.g., it is established that China is blocking a significant portion of foreign commercial traffic, as described above, by a wide consensus of credible reporting regardless of whether China has issued a statement or not), or China-issued navigation/airspace prohibitions covering Taiwan's main island's approach lanes that are actively enforced so that most foreign commercial access is denied.
A qualifying blockade is not:
- Military or naval exercises or drills (established with warning areas or NOTAMs that do not actively stop third-country ships/aircraft and do not materially deny access).
- Purely economic or coercive measures (e.g., sanctions, customs delays, fishing bans, cyber/GPS jamming) without physical interdiction or enforced closure).
- Weather/accident-related closures or voluntary rerouting by operators absent PRC enforcement.
- Islet-only incidents that do not involve the main island of Taiwan.
- Seizure or inspection of a single vessel/aircraft by itself, unless part of an enforced pattern that denies access as defined above.
The resolution source for this market will be a broad consensus of credible reporting.
