1. Introduction: “Taiwan Contingency” Is Not Only an Invasion Scenario

In public discourse, “a Taiwan crisis” is often equated with a full-scale PLA assault.
However, national-security professionals define a Taiwan contingency far more broadly as:

Any event—military, economic, political, informational, or hybrid—that significantly undermines Taiwan’s security and could draw in the United States, Japan, and regional actors.

This report organizes ten plausible scenarios across multiple domains to illustrate how a crisis could realistically unfold.

Scenario 1: Limited Military Clashes (Localized Kinetic Engagement)

Overview
Small-scale military incidents occur in the Taiwan Strait or surrounding airspace—missile shots near Taiwan, naval skirmishes, or warning shots between fighter jets.

Key Features

Duration: days to weeks
China demonstrates coercive intent without committing to escalation
Both sides attempt to contain escalation
Markets react sharply; military scope remains localized

This is one of the more plausible short-term scenarios.

Scenario 2: Seizure of Outlying Islands (Gradual Encroachment Strategy)

Overview
PLA forces move against offshore islands such as Kinmen or Matsu, which are far closer to mainland China than Taiwan proper.

Key Features

Avoids immediate U.S. military entanglement
Tests international response
If global reaction is muted, Beijing may escalate pressure toward Taiwan proper

This represents a stepwise approach rather than all-out war.

Scenario 3: Full-Scale Invasion of Taiwan Proper (Worst-Case Scenario)

Overview
A coordinated campaign involving missile strikes, cyberattacks, air operations, naval blockade, and amphibious landings aimed at capturing major cities like Taipei and Kaohsiung.

Key Features

Requires extreme levels of preparation, logistics, and political risk
Would almost certainly trigger U.S. and Japanese intervention
Devastating global economic impact—particularly on semiconductors
Low probability in the near term given China’s current capabilities and economic conditions

This is the “Hollywood scenario,” but not the most realistic in the next several years.

Scenario 4: Maritime Blockade or Quasi-Blockade

Overview
China imposes a de facto blockade under the guise of “maritime security operations” or “military exercises,” severely restricting Taiwan’s shipping routes.

Key Features

No direct attack on Taiwan territory
Major disruptions to energy imports and export logistics
Immediate global shock due to halted TSMC shipments
Hard for the U.S. to ignore, yet ambiguous enough to delay escalation

This is considered one of the most strategically potent levers for Beijing.

Scenario 5: Cyberattacks on Critical Infrastructure

Overview
Coordinated attacks target Taiwan’s power grid, telecom networks, financial systems, and government platforms.

Key Features

“Silent contingency”—no physical confrontation
Highly deniable; attribution is difficult
Often paired with disinformation to magnify chaos
May serve as a prelude to more coercive actions

This scenario is widely assessed as high-probability.

Scenario 6: Large-Scale Information and Psychological Warfare

Overview
China intensifies cognitive warfare aimed at dividing Taiwanese society and eroding trust in democratic institutions.

Key Features

Narratives such as “The U.S. will not defend Taiwan” or “Resistance is futile”
Social-media manipulation, propaganda, and influence campaigns
Objective: weaken morale and political cohesion
No bullets fired, but long-term strategic impact is profound

Many analysts consider this the most consequential non-kinetic threat.

Scenario 7: Political Subversion or Internal Destabilization

Overview
Efforts to promote pro-Beijing parties, co-opt local elites, interfere in elections, or orchestrate political crises.

Key Features

Appears “legal” or “democratic” from the outside
Creates internal paralysis or a shift toward pro-Beijing policies
Difficult for foreign governments to counter
Low-cost, high-impact strategy for Beijing

A political takeover without firing a shot is arguably Beijing’s ideal outcome.

Scenario 8: Economic Coercion and Dependency Strategy

Overview
China leverages trade, tourism, finance, and supply-chain dependency to force political concessions.

Key Features

Targeted sanctions on Taiwanese industries
Restrictions on imports/exports or investment approvals
Gradual shift toward a dependency-based “economic unification”
Hard to classify as a crisis, yet strategically corrosive over time

This scenario is already unfolding at low intensity.

Scenario 9: Escalation Triggered by Accident or Miscalculation

Overview
A collision, misinterpretation of radar signatures, or accidental missile launch triggers retaliatory actions from both sides.

Key Features

Neither side intended war
Domestic politics and national pride make de-escalation difficult
Echoes Cold War incidents involving U.S.–Soviet forces
Crisis stability depends on hotline reliability and leadership decision-making

This scenario highlights the inherent danger of high-tempo military operations.

Scenario 10: Spillover from Broader U.S.–China Confrontation

Overview
A crisis originating outside Taiwan—South China Sea, East China Sea, Middle East, or cyber domain—intensifies U.S.–China rivalry and elevates military posture around Taiwan.

Key Features

Taiwan becomes a “secondary battlefield”
U.S. deployments increase due to global tensions
China responds with counter-deployments near the Strait
Misunderstandings or standoffs escalate into a localized crisis

This is an indirect but very plausible pathway to a Taiwan emergency.

Summary: Probability Landscape Across the 10 Scenarios

Most likely in the near term

Scenario 5: Cyberattacks
Scenario 6: Information warfare
Scenario 8: Economic coercion

Moderately plausible

Scenario 1: Limited military clashes
Scenario 2: Outlying island seizure
Scenario 4: Blockade
Scenario 9: Accidental escalation

Low probability but maximum impact

Scenario 3: Full-scale invasion
Scenario 10: Global U.S.–China confrontation spilling into Taiwan

Conclusion

“Taiwan contingency” does not equate solely to a PLA amphibious assault.
Rather, it encompasses a spectrum of gray-zone, hybrid, political, and economic pressures—many of which can escalate without warning.

Understanding these ten scenarios allows policymakers, corporations, and investors to:
