The current crisis surrounding the Taiwan Strait did not emerge overnight. Its roots trace back to the founding of the People's Republic of China in 1949 and the Kuomintang government's retreat to Taiwan, resting on the structural contradiction of a 77-year 'unfinished civil war'.
During the Cold War, the Taiwan Strait experienced three crises (1954-55, 1958, 1995-96). In each instance, U.S. military intervention or deterrence prevented escalation. The Third Taiwan Strait Crisis of 1995-96, in particular, was triggered by President Lee Teng-hui's visit to the U.S., leading China to conduct missile exercises and the U.S. to deploy two aircraft carriers in response, an event with many similarities to the current situation.
However, what fundamentally distinguishes the 2026 crisis from the past is the structural change in the military balance. In 1996, the Chinese Navy was merely a brown-water navy (coastal navy) and lacked the capability to counter U.S. aircraft carrier strike groups. Yet, over the past 30 years, China has consistently increased its military spending by over 7% annually, with its publicly announced defense budget reaching approximately $233 billion in 2025 (estimated to be effectively $350-400 billion). Through the establishment of a three-aircraft-carrier system, mass production of Type 055 destroyers, and deployment of DF-21D/DF-26 anti-ship ballistic missiles, China has established an A2/AD (anti-access/area denial) strategy, successfully dramatically raising the cost of U.S. military intervention around Taiwan.
This shift in military balance fundamentally altered the political calculus of the Xi Jinping administration. Having secured an unprecedented third term at the 22nd National Congress of the Communist Party of China in October 2022, Xi Jinping positioned Taiwan's unification as central to the 'great rejuvenation of the Chinese nation' and explicitly stated that he would 'not renounce the use of force.' At the Second Session of the 14th National People's Congress in 2024, the 'historic mission of national reunification' was re-emphasized, functioning not merely as rhetoric but as a policy commitment.
Several direct triggers contributed to the intensification of military pressure in early 2026. First, Taiwanese President Lai Ching-te, who took office in May 2024, has shown a stance emphasizing Taiwan's sovereignty even more strongly than his predecessor, Tsai Ing-wen. Second, the United States accelerated arms sales to Taiwan from late 2025 into 2026, supporting the strengthening of asymmetric capabilities. Third, Japan is advancing the reinforcement of its Nansei Islands defense, effectively institutionalizing its involvement in a Taiwan contingency. These developments are perceived by Beijing as 'gradual independence,' providing a pretext for increased military pressure.
The geoeconomic context is also crucial. Taiwan, centered around TSMC, accounts for approximately 65% of the world's advanced semiconductor manufacturing, and instability in the Taiwan Strait would have a devastating impact on global technology supply chains. While the Biden administration's CHIPS Act is progressing in building a domestic semiconductor manufacturing base in the U.S., TSMC's Arizona factory will not be fully operational until 2028 or later, meaning dependence on Taiwan has not yet been resolved. This 'silicon shield' — the argument that Taiwan's semiconductor industry acts as de facto deterrence — could paradoxically make Taiwan a target for military adventurism. This is because it creates an incentive for China to achieve unification before it achieves semiconductor self-sufficiency.
From the perspective of international order, Russia's invasion of Ukraine (2022) has had a dual impact on the Taiwan situation. On one hand, it demonstrated international rejection of changing the status quo by force, which has a deterrent effect on China's military actions. On the other hand, it exposed the limits of sanctions against Russia and 'sanctions fatigue' in the West, increasing the risk that China might judge the economic costs to be manageable. Furthermore, the diversion of U.S. military resources due to the war in Ukraine raises questions about the credibility of deterrence in the Indo-Pacific.
The 2026 Taiwan Strait crisis indicates that the accumulation of these structural changes is approaching a critical point. This is not merely the potential for a regional conflict, but a situation that tests the very foundation of the post-World War II international order — particularly the prohibition of changing the status quo by force and the free trade system.
The delta: China's military pressure has qualitatively transformed from 'periodic shows of force' to 'normalized coercion.' The increase in activity in early 2026 is not merely a quantitative expansion but signifies the establishment of a 'new normal,' combining the display of combat capabilities with psychological pressure, as seen in the deployment of aircraft carriers east of Taiwan and the increased frequency of joint landing exercises. In response, the U.S.-Japan alliance has also shown a qualitative shift in the form of enhanced readiness, indicating that the spiral of conflict is becoming entrenched at a higher level.
🔍 Between the Lines — What the News Isn't Saying
The biggest focus that official reports don't convey is that the true purpose of China's intensified military pressure is not Taiwan's unification itself, but rather the maintenance of Xi Jinping's domestic power base. Amidst an economic slowdown following the real estate bubble collapse and deepening youth unemployment, as the Communist Party's pillar of legitimacy—the 'promise of prosperity'—wavers, the nationalist narrative of a 'mission of unification' serves to bolster the regime's cohesion. Another reality that governments publicly deny is that U.S. 'strategic ambiguity' is no longer functioning adequately as a deterrent, and a shift towards 'strategic clarity' is being discussed behind the scenes among stakeholders. While maintaining ambiguity has the advantage of lowering the cost of consensus-building within alliances, the balance between this benefit and the risk of allowing China to miscalculate that the U.S. 'might not intervene' is rapidly eroding.
NOW PATTERN
Spiral of Conflict × Overextension of Power × Alliance Fissures
In the Taiwan Strait, the 'spiral of conflict' acts as a dominant dynamic, with military signaling exchanges creating a self-reinforcing escalation cycle. Simultaneously, China's 'overextension of power' and 'alliance fissures' within Western alliances are reducing the predictability of the situation.
Intersection of Dynamics
The three dynamics of the spiral of conflict, overextension of power, and alliance fissures are interconnected in the Taiwan Strait crisis, dramatically increasing the complexity of the situation.
First, the spiral of conflict and the overextension of power are paradoxically related. The more China intensifies military pressure, the more it invites countermeasures from the international community, and these countermeasures then become pretexts for further pressure. However, simultaneously, this military escalation depletes China's economic and diplomatic resources, increasing the risk of overextension. Nevertheless, for Xi Jinping, retreat on the Taiwan issue is politically impossible, leading to a dilemma of 'unstoppable escalation' versus 'unsustainable costs.' This structure makes it difficult to predict the upper limit of escalation based on rational calculations.
Next, alliance fissures complicate the dynamics of the spiral of conflict. When allied responses are unified, China receives clear signals, enabling cost calculations. However, if there are differing levels of commitment within the alliance, China may perceive it as 'divisible,' creating an incentive for more adventurous actions. In particular, U.S. strategic ambiguity — neither promising nor denying Taiwan's defense — destabilizes the balance between deterrence and assurance. While this ambiguity is inherently designed to curb escalation from both sides, when combined with shifts in military balance and divergences within alliances, it tends to broaden the scope for miscalculation.
Furthermore, the overextension of power and alliance fissures create an 'asymmetric dilemma.' China, with its centralized decision-making structure, can act swiftly and decisively, but resource constraints lead to accumulating costs for sustained pressure. Conversely, the allied side, with its decentralized decision-making structure, can mobilize overwhelming resources but incurs high costs for consensus-building, lacking speed and consistency in response. This asymmetry favors China in short-term crisis situations and the allied side in long-term wars of attrition. Therefore, China has an incentive to create faits accomplis before its 'window' closes, which carries the risk of further accelerating the spiral of conflict.
At the intersection of these three dynamics lies the geoeconomic factor of the semiconductor supply chain. Global dependence on Taiwan's TSMC astronomically raises the cost of conflict, while also being part of China's incentive for unification. Moves towards reducing dependence on Taiwan through the U.S. CHIPS Act and Japan's semiconductor strategy could alleviate the spiral of conflict in the long term, but paradoxically, during the transition period, they may stimulate China's perception of a 'window of action,' increasing short-term instability.

2022: Nancy Pelosi's Visit to Taiwan and China's Military Exercises
Spiral of Conflict and Escalation Dynamics
Structural similarities to the present: China's large-scale military exercises triggered by Pelosi's visit to Taiwan functioned as a rehearsal for a Taiwan blockade, and subsequently, the level of military activity was permanently raised as a 'new normal.' An example of the ratchet effect of escalation — once tension levels rise, they do not easily return to their previous state.
Patterns Shown by History
The most important lesson from historical patterns is that 'the spiral of conflict has a ratchet effect.' That is, once military tension escalates, it does not easily revert to its previous level, and each crisis raises the baseline for the next. The normalization of Chinese military activities after Pelosi's visit in 2022 is precisely this case, and the intensification of military pressure in 2026 signifies further escalation from that baseline.
However, at the same time, the 1962 Cuban Missile Crisis provides an important counterexample where the spiral of conflict between nuclear powers did not lead to direct confrontation. Its success factors were the existence of back-channel diplomacy, the construction of compromise solutions that both leaders could present as 'victories,' and explicit communication to prevent accidental military clashes.
Applying this to the current Taiwan Strait, the core question for the 2026 crisis is where it falls between a 1996-style 'crisis resolvable by military demonstration' and a 1914-style 'uncontrollable escalation due to alliance chain reactions.' While China's military capabilities have improved incomparably since 1996, the logic of nuclear deterrence continues to have the effect of restraining full-scale war. This tension between 'changed capabilities' and 'continued deterrence' is the greatest uncertainty in predicting future developments.
🔮 Next Scenarios
China maintains a high level of military pressure around Taiwan but refrains from direct use of force. Throughout 2026, ADIZ incursions fluctuate between 120-180 times per month on average, and regular large-scale exercises are conducted. The United States continues arms sales to Taiwan and maintains forward-deployed forces in the Western Pacific, but provocations such as direct transits of the Taiwan Strait are managed restrictively. Japan completes the reinforcement of its Nansei Islands defense and advances the concretization of U.S.-Japan contingency plans for Taiwan. Taiwan gradually strengthens its military capabilities towards a defense budget target of 3% of GDP, accelerating the development of asymmetric capabilities (mine warfare, anti-ship missiles, drones). Economically, China's economic pressure on Taiwan continues, with expanded import restrictions on agricultural products and an increase in cyberattacks. TSMC's overseas diversification strategy accelerates, but the concentration of cutting-edge processes at its Taiwan headquarters continues. In this scenario, several 'near-miss' incidents — abnormal close approaches between Chinese and Taiwanese military aircraft, or accidental maritime contacts — occur, but both sides' escalation management mechanisms (even if limited) function, and a full-scale military conflict is avoided. By the end of 2026, a 'new new normal' is established, with tensions remaining high but stable at a manageable level.
Implications for Investment/Action: Scale and frequency of Chinese military exercises stabilize at current levels. Limited reopening of U.S.-China military hotlines. Steady implementation of Taiwan's increased defense budget. On-schedule progress of TSMC's overseas factory construction.
Some form of 'tacit understanding' regarding the Taiwan issue is reached between the U.S. and China, leading to a gradual easing of military tensions. The key to this scenario is that the deterioration of China's domestic economy deprives Xi Jinping of the leeway for external adventurism, creating a situation where international stability is needed for economic recovery. Specifically, the deepening of China's real estate crisis and the manifestation of local government debt issues slow the pace of military spending expansion. Simultaneously, strengthened U.S. export controls on semiconductors to China deal a blow to China's technological self-sufficiency strategy, creating certain technological bargaining chips. Against the backdrop of this economic pressure, a U.S.-China summit or high-level dialogue materializes, reaffirming the 'status quo in the Taiwan Strait.' China reduces the frequency of ADIZ incursions to around 80 times per month and scales down large-scale exercises. However, there is no retreat from the 'One China' principle, and the accumulation of military capabilities continues. The U.S. adjusts the pace of arms sales and refrains from high-level visits to Taiwan. The Taiwan Strait returns to a state of 'cold peace,' but the structural roots of tension are not resolved. In this scenario, short-term risks to the semiconductor supply chain decrease, and TSMC stock prices enter a recovery trend. Overall economic confidence in the region improves, and foreign direct investment inflows also recover to some extent.
Implications for Investment/Action: Announcement of a U.S.-China summit. Visible decrease in the scale and frequency of Chinese military exercises. Significant deterioration of China's domestic economic indicators. Resumption of U.S.-China military exchanges.
An accidental military clash or intentional escalation leads to a limited military confrontation in the Taiwan Strait. The most probable triggers are an aerial collision between Chinese and Taiwanese military aircraft (a Taiwan version of the 2001 EP-3 incident), 'inspection' (boarding) of Taiwanese supply vessels by the Chinese Navy, or the exercise of pressure on Taiwan's outlying islands (such as the Pratas Islands). In this scenario, China may declare the partial implementation of a maritime blockade against Taiwan — for example, establishing 'security inspection zones' for specific shipping lanes. This would be a 'gray zone' action not accompanied by a formal declaration of 'war,' but it would directly threaten Taiwan's economic lifeline and compel a response from the international community. The United States would respond with naval transits of the Taiwan Strait and freedom of navigation operations but would seek to avoid direct engagement with China. Japan would be involved through granting permission for the use of U.S. bases in Japan and providing logistical support, but direct military action by the Self-Defense Forces would be limited. The international community would discuss the imposition of economic sanctions against China, but reaching consensus on the scope and intensity of sanctions would take time. The semiconductor supply chain would face severe disruption, with shipments from TSMC's Taiwan factories temporarily halted. Global semiconductor prices would surge by 50-100%, devastating the automotive and electronics industries. Global stock markets would experience a sharp decline of 15-25%, and the annual $5.3 trillion in trade passing through the Taiwan Strait would be significantly disrupted. Crude oil prices would exceed $120 per barrel, and the risk of global stagflation would rapidly increase.
Implications for Investment/Action: Signs of Chinese military pressure on Taiwan's outlying islands. Moves by the Chinese Navy to establish 'security inspection zones' around Taiwan. Complete breakdown of U.S.-China military communications. Surge in 'unification'-related propaganda in Chinese domestic media. Large-scale mobilization of Chinese reservists and accumulation of logistical supplies.
