China’s coast guard has conducted repeated “law-enforcement” patrols east of Taiwan since June 2026, inspecting merchant vessels and asserting jurisdiction over waters outside Taipei’s claims, actions widely viewed as rehearsals for quarantine or blockade tactics. These operations, paired with PLA exercises emphasizing joint blockade and anti-access measures, have prompted Taiwan to run tabletop drills simulating ship inspections, seizures, and supply disruptions while accelerating defense procurement. At the same time, reduced air incursions, ongoing U.S.-China summits, and the economic costs of escalation have kept tensions below the threshold for a full maritime blockade. Traders therefore assign the “No” outcome a 96.5 percent implied probability, reflecting the view that Beijing’s current gray-zone campaign is more likely to persist than to trigger the major international confrontation a 2026 blockade would entail. Late-year diplomatic shifts or a sharp miscalculation remain the principal variables that could still alter that assessment.

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.
