▸Assessment Details

Why NowMED

PLA exercises have normalized encirclement patterns and crossed the median line as a baseline. Coast Guard quarantine drills are increasingly indistinguishable from operational rehearsals.

Strategic TriggerHIGH

PLA declares an extended live-fire exclusion zone encircling Taiwan, coupled with maritime quarantine of strategic cargo.

Pressure PointsHIGH

·TSMC fabs — global semiconductor chokepoint
·Bashi Channel and Miyako Strait transit
·Submarine cables carrying Asia-Pacific data
·US treaty obligations vs strategic ambiguity

Possible ConsequencesMED

·Global tech supply chain shock within weeks
·Allied naval mobilization across the Pacific
·Sanctions regime against Chinese financial system
·Risk of accidental kinetic engagement near AOR

Market & Strategic ImpactMED

Semiconductors
Severe supply shock risk — TSMC offline ripples through global tech.
Asian Equities
Increased volatility risk; TWSE, KOSPI, Nikkei drawdown likely.
Shipping Lanes
Pacific reroutes via Lombok/Sunda; freight rates spike.
USD / JPY
Possible JPY safe-haven bid; USD firm on liquidity demand.
Gold
Potential safe-haven reaction on sustained allied mobilization.
Global Supply Chains
Likely consumer electronics and auto-sector disruption.
Defense Sector
Sustained bid on US, Japanese, Korean primes.
Escalation Probability
High risk of accidental kinetic engagement near AOR.

Escalation RiskMED

CRITICAL — kinetic risk window inside the 30-day horizon.

Alliance ReactionsLOW

·Japan invokes alliance consultations; SDF surges to Ryukyus
·Australia leans on AUKUS posture; submarine deployments accelerate
·South Korea balances exposure carefully; limited overt commitment
·EU issues sanctions framework against Chinese financial system

Watch IndicatorsHIGH

·PLA exercise duration extending past 96 hours without standdown
·Coast Guard quarantine of strategic cargo (semiconductors, LNG)
·Bashi / Miyako Strait closures to civilian traffic
·Allied naval surge into the Philippine Sea

Next MovesLOW

7 Days

·Exercise notice extends; civil aviation reroutes
·Beijing demands inspection rights on Taiwan-bound cargo

30 Days

·Selective quarantine of dual-use cargo; insurance reprices
·US-Japan-Australia naval mobilization; AUKUS posture shifts

90 Days

·Either tactical de-escalation after market shock, or hardening into a sustained quarantine regime
·Semiconductor supply chain begins permanent diversification away from Taiwan

What Invalidates This AssessmentHIGH

·Cross-strait political dialogue resumes with substance
·US-China strategic stability framework re-emerges
·Major Chinese economic crisis forcing internal focus

Final AssessmentMED

A blockade pressures Taipei faster than allied navies can respond. The clock — not the missile — is the weapon. Time-to-resupply defines the outcome.
