Taiwan and the Silicon Chokepoint
Why one island shapes the military, trade, and technology policy of every major power. The single most concentrated point of geopolitical risk in the modern economy.
(by a single company, TSMC)
(roughly the population of Australia)
(similar in size to the Netherlands or Switzerland)
A note on framing. Taiwan is a topic where panic and dismissal are both common. Neither helps. The actual situation is unusually concrete - one island, one company, a measurable strait, two governments with public commitments - and the data is unusually clear about what is and is not at stake. The page below tries to walk through the situation as a careful adult reader would want it explained, without either war drums or false reassurance.
Why Taiwan matters
Taiwan is a small island a hundred miles off the coast of mainland China. It has 24 million people, a vibrant democracy with regular peaceful changes of government, and an economy that ranks roughly 21st in the world. None of that, by itself, would make it the centre of strategic concern for the United States, Japan, Europe, China, or anyone else. What makes Taiwan central is a single industry: the manufacturing of advanced semiconductors, also known as computer chips.
The chips that run modern smartphones, data centres, cars, missiles, satellites, medical devices, and almost every other piece of complex electronics in the world economy come, in disproportionate share, from a single company called Taiwan Semiconductor Manufacturing Company - TSMC for short. TSMC is the world's largest "foundry" - a company that does not design chips of its own but makes them for other companies. Apple, Nvidia, Qualcomm, AMD, and a long list of the world's largest technology companies design chips and then send the designs to TSMC to be physically manufactured.
On the most advanced chips - the ones with the smallest features, the highest performance, the highest profit margins, and the most strategic importance - TSMC has a share approaching 90% of the world's production. There is exactly one other company on the planet (Samsung in South Korea) capable of producing chips at this level, and Samsung is well behind TSMC by every measure that matters at the cutting edge. The most advanced chips themselves depend on machines made by a single Dutch company called ASML. The dependency chain narrows as you go up the technology ladder, and the very top of the ladder runs through a small island in the South China Sea.
That concentration is what makes Taiwan a chokepoint rather than a country among many. A serious disruption of Taiwanese chip production - whether from an invasion, a blockade, a natural disaster, or a major industrial accident - would produce shortages and price increases across most of the modern economy within months. Estimates of the global cost of a complete loss of Taiwanese chip production range from several trillion dollars in the first year to substantially more if the disruption persisted. There is no scenario in which the world economy absorbs a Taiwan crisis without significant pain.
How TSMC actually got there
The story of TSMC's rise is worth knowing because it explains why the concentration is genuinely hard to undo. TSMC was founded in 1987 by Morris Chang, an American-trained engineer who returned to Taiwan with a then-unusual idea: a chip company that did not design any chips of its own, only manufactured them for other companies. At the time, every major semiconductor company designed and made its own chips. The "fabless" design model that exists today (where companies like Apple, Nvidia, and Qualcomm design chips and outsource the manufacturing) only became possible because TSMC made the foundry model viable.
From the late 1990s onward, TSMC invested heavily in a continuous cycle of building newer, more advanced manufacturing facilities. Each generation cost more than the last. By the 2010s, the cost of building a state-of-the-art chip factory had risen to about $20 billion, and only three companies in the world were even attempting it: TSMC, Samsung, and Intel. By the 2020s, Intel had fallen behind technically, and Samsung was struggling to match TSMC at the leading edge. TSMC kept investing through every economic cycle, kept hiring the best engineers, and kept its factories running with high precision. The result was a slow accumulation of advantages that compounded into near-monopoly at the cutting edge.
The other piece of the story is geographic. About 90% of TSMC's manufacturing capacity is located on the island of Taiwan. The company is now building factories in Arizona, Japan, and Germany - a deliberate response to the chokepoint risk - but those factories are smaller, are running behind schedule, and will not catch up to the Taiwan facilities for at least a decade. The same is true for Samsung's overseas expansions and Intel's struggling foundry effort. As of 2026, anyone who needs the very best chips needs Taiwan.
Where the world's chips actually come from
The semiconductor industry is more spread out than the headline suggests, but the leadership at the top is concentrated. The numbers below give a rough picture of where chip manufacturing happens, who designs the chips, and who makes the equipment used to build them.
The picture is one of multiple chokepoints rather than a single one. Taiwan is the most concentrated and most exposed, but a serious disruption at any of the major nodes - the Dutch lithography machines, Japanese materials, Korean memory, or US-designed software - would also cause significant pain. The system that produces the world's chips is a deeply interdependent network with surprisingly few backup options. Building new ones takes a decade and tens of billions of dollars per node.
The China question
Beijing's official position is that Taiwan is a province of China that has been temporarily separated from the mainland and must eventually be reunified. It has held this position consistently since 1949, when the losing side of the Chinese civil war retreated to Taiwan and continued to call itself the Republic of China. Beijing has stated, also consistently, that it prefers peaceful reunification but reserves the option to use force if peaceful means fail. Both statements have been Chinese government policy for the entire lifetimes of most readers.
What has changed is the underlying military balance. In the 1990s and 2000s, the United States Navy could have intervened in a Taiwan crisis with high confidence of success. By the 2020s, that confidence has eroded. China has built more naval ships, more anti-ship missiles, more air defence, and more missile-based systems specifically designed to make a US intervention costly. The Pentagon's own war games of recent years no longer assume clean American victory in a Taiwan scenario; some publicly-released versions show very expensive American losses or tied outcomes. The strategic geography of the Western Pacific has shifted, and Taiwan sits at the centre of it.
What has not changed is the underlying difficulty of an actual military operation. Taiwan is a hundred miles off the Chinese coast, separated by a strait that is rough most of the year. The mountainous east coast of the island is hard to land on. The west coast (where landing is feasible) is heavily fortified with prepared positions, missile sites, and the ability to flood beaches. Modern amphibious invasions are extraordinarily difficult under the best of circumstances, and a Taiwan invasion would be one of the largest amphibious operations in history. China has not attempted an opposed amphibious landing of any size since 1949. The military effort would be massive, and the political and economic costs would be enormous regardless of whether the invasion succeeded.
What the scenarios actually look like
Discussion of "what happens to Taiwan" tends to collapse into a binary: peace or invasion. The reality is a spectrum of pressure and risk, only the most extreme version of which involves a full military assault. The middle of the spectrum is more likely than either end, and is also where most of the strategic consequences would actually play out.
Slow squeeze. China increases pressure through diplomacy, economic restrictions, intelligence operations, cyber harassment, and limited military exercises designed to wear down Taiwanese morale and the willingness of Taiwan's allies to defend it. This is the version that has been quietly running for the last decade and would likely intensify if Taiwan moved toward formal independence or if China felt that time was working against it. No clear breaking point; a long, grinding pressure campaign.
Blockade or quarantine. Chinese naval and air forces declare some level of inspection or restriction on shipping to Taiwan. Taiwan imports almost all of its energy and a large share of its food; even a partial blockade could produce serious shortages within weeks. The United States and its allies would face a hard choice between accepting the blockade (and the precedent it sets), running ships through it (and risking direct confrontation), or escalating in some other way. Several careful military analysts now think this is more likely than a full invasion.
Limited military action. China seizes one of Taiwan's outer islands (Kinmen, Matsu, the Pratas, or one of the Spratlys) as a demonstration of capability and political will, hoping to fracture Taiwanese resistance and Western unity without triggering a full war. The risk is that "limited" actions in tense situations rarely stay limited.
Full invasion. A direct amphibious assault on the main island, intended to seize key cities and government infrastructure rapidly enough that the United States and Japan cannot effectively intervene. This is the most catastrophic scenario and the one that Pentagon planning focuses on, partly because it is the scenario where the consequences are most severe even if its probability is lower than other paths. Most serious analysts put the probability of a successful Chinese invasion in the next decade in the single digits, but the probability of an attempt - successful or not - is probably higher.
Crisis followed by negotiation. A serious incident (an accidental shoot-down, a misread military exercise, an electoral provocation in Taiwan) escalates briefly, both sides pull back from the brink, and a new framework of management emerges. This is what happened after the 1995-96 Taiwan Strait crisis and the 2022 Pelosi visit. Plausible if the system can be defused quickly enough; harder if either side cannot walk back from a public commitment.
The paths from here
None of the realistic paths is comfortable. The base case is "more of the same, with quietly rising tension," but several other paths have non-trivial probability. Each is worth thinking through.
Status quo persists, with managed tension
Taiwan continues to operate as a self-governing democracy, China continues to claim it without acting, and a careful set of unwritten understandings keeps the peace. Both sides issue strong rhetoric publicly while carefully avoiding the actions that would force a confrontation.
Will it happen? This is the base case and has been the actual situation for seventy-five years. It is also the path most fragile to a single misstep. The probability over the next decade is high but not certain - somewhere around 60 to 75% depending on which careful analyst you ask.
A slow squeeze that wears Taiwan down
China increases pressure on Taiwan through economic, diplomatic, and grey-zone military moves without crossing the threshold of open war. Over years, the political will of Taiwan to resist erodes, the willingness of allies to defend it weakens, and at some point Taipei accepts a "framework agreement" that effectively ends its de facto independence.
Will it happen? This is the path Beijing has reportedly hoped for, and has been quietly pursuing. The trouble for China is that the pressure has tended to harden Taiwanese resistance and pull the United States closer rather than the opposite. A slow squeeze that succeeds is plausible over a thirty-year horizon, hard to imagine in ten.
Blockade or partial quarantine
China announces some form of inspection regime, exclusion zone, or trade restriction on Taiwan, forcing a binary choice on the United States and its allies. The blockade may or may not include a small kinetic component (a few ships fired on, a few aircraft turned back).
Will it happen? This is the scenario several careful military analysts now consider most likely if China decides to actively pressure the situation. It uses China's strongest military advantages (sea and missile power close to its coast) and exploits the West's weakest political dimension (the difficulty of choosing which crisis to escalate). Probability is harder to estimate but likely higher than full invasion - perhaps 5 to 15% over a decade.
Full invasion attempt
A direct amphibious operation aimed at seizing the main island. The US and Japan likely intervene. The conflict spreads. Casualties on every side are large; the global economic disruption is severe; the political consequences reshape Asian alliances for decades.
Will it happen? Most careful analysts put the probability in the low single digits over the next decade. Not zero. The combination of public Chinese commitment to reunification, the slow erosion of US deterrence, and the possibility of misperception in either capital makes it real enough to plan against. The high consequences of the scenario justify a much larger share of strategic attention than the probability alone would suggest.
Negotiated framework arrangement
Some new political settlement is reached - perhaps an updated version of the 1992 Consensus, perhaps something genuinely new. Taiwan retains substantial self-government in exchange for clear commitments not to declare formal independence; China accepts the de facto status quo in exchange for clear guarantees against further Western military entrenchment.
Will it happen? This is the path most professional diplomats in both Washington and Beijing privately say they would prefer. The trouble is domestic politics on every side: no Chinese leader can be seen accepting a de facto independent Taiwan, no Taiwanese government can be seen accepting Chinese sovereignty, and no US administration can be seen abandoning a democratic ally. The conditions for a real framework remain difficult.
Internal Chinese political shift changes the picture
A change in Chinese leadership, a domestic crisis that absorbs Beijing's attention, or a meaningful liberalisation of the Chinese system shifts the relationship into a different shape. Less external pressure on Taiwan, more focus on domestic recovery, possibly different rhetoric.
Will it happen? Genuinely unpredictable. Xi Jinping has consolidated power further than any leader since Mao, and a clean leadership succession is not yet visible. A serious Chinese economic crisis is more probable than a clean political shift, and the consequences of an economic crisis for Taiwan policy could go either way (more pressure as a distraction, or less pressure as Beijing focuses inward).
Internal Taiwan political shift toward unification
A future Taiwan government, perhaps under different demographic or economic pressures, moves toward voluntary closer association with the mainland. The path is much less likely than its political opposite (Taiwan moving toward formal independence) but cannot be ruled out over a thirty-year horizon.
Will it happen? Polling consistently shows that the share of Taiwanese identifying as "Taiwanese only" has been growing for thirty years and "Chinese only" identity has been shrinking. A voluntary path toward unification looks more remote each year, not less. Beijing is aware of this and one reason for the urgency on its side is that the demographics of Taiwanese opinion are running against it.
The realistic forecast is, again, a mix: the base case is continued status quo with rising tension; the middle scenarios (slow squeeze, blockade) are the ones with real probability over a decade; the worst case (full invasion) is unlikely but not so unlikely as to be ignored; and a clean negotiated framework remains the least bad outcome but the hardest to actually build. The world economy and the global chip industry are now hostage to choices that have not yet been made in Taipei, Beijing, and Washington.
Where serious analysts disagree
Taiwan is one of the topics where careful disagreement is much more illuminating than confident prediction. Each of the readings below is held by named analysts whose work is worth reading directly, and the data does not cleanly resolve any of them.
A Chinese move on Taiwan is more likely this decade than commonly assumed
The window in which China can act decisively while still being able to absorb the cost may be closing. Chinese demographics are about to bite hard. The economic slowdown will get worse before it gets better. Xi Jinping's domestic legacy depends on visible progress on Taiwan. The temptation to act before time runs out grows each year.
Held by: Hal Brands and Michael Beckley (the "Danger Zone" thesis), parts of the US Department of Defense, and a number of Asian strategists. Their data on Chinese capability and motivation is solid; the open question is how much weight to give to the political-cost side of Beijing's calculus.
Blockade is more plausible than invasion
An invasion is enormously difficult, requires perfect execution, and would visibly fail or succeed within weeks. A blockade leverages China's strongest assets, can be calibrated for political effect, and forces the United States to choose between accepting it and starting a war. The Western strategic establishment has spent the last decade preparing for invasion and may be under-prepared for the more likely scenario.
Held by: Lonnie Henley (former US intelligence official), Bonnie Glaser (German Marshall Fund), and a number of naval analysts. Their argument has gained traction in recent Pentagon assessments and is increasingly mainstream within the strategic-planning community.
Even a successful invasion would not give China the chips
TSMC's most advanced fabrication facilities depend on hundreds of suppliers, thousands of trained engineers, and constant technical support from Western partners. A military takeover would almost certainly result in destruction of the most advanced equipment, evacuation of key staff, and a global cut-off of supplies. The chips matter, but the chips are not actually obtainable through force.
Held by: Chris Miller (author of "Chip War"), and most semiconductor industry analysts. The strategic implication is that the chip dependency is more of a constraint on Chinese options than a prize Beijing could realistically capture.
The bigger risk is miscalculation, not strategic decision
Both Beijing and Washington have publicly committed to positions they cannot easily walk back. Both have domestic political pressures that push them to project firmness. The most likely path to crisis is not a deliberate decision by either side to start a war, but a misread incident that escalates faster than either capital can contain it. The strategic conditions resemble pre-1914 Europe more than they resemble the Cold War.
Held by: Graham Allison (Harvard) and the broader "Thucydides Trap" school, plus historians of the 1914 crisis. Their argument is that risk management has to focus on the conditions that allow miscalculation, not just on each government's stated intentions. Allison's specific framework - that rising-versus-ruling-power transitions historically end in war about 75% of the time - has been heavily contested on case-selection grounds (Richard Hanania, Arthur Waldron, and others argue the dataset is constructed to support the conclusion); the underlying point about miscalculation risk does not depend on Allison's specific statistical claim being correct.
Taiwan can hold longer than commonly thought
The combination of difficult terrain, prepared defenders, modern anti-ship and anti-air capabilities, and the speed at which the United States and Japan could intervene means that even a serious Chinese assault is far from guaranteed to succeed quickly. The "Ukraine model" - where Western support enabled a smaller country to inflict large costs on a larger invader - is more applicable to Taiwan than is sometimes assumed.
Held by: Lyle Goldstein, parts of the US Marine Corps, and "deterrence by denial" strategists. The implication is that the right Western strategy is to make a Chinese assault clearly unprofitable, rather than to commit to direct intervention in advance.
None of these readings is fully right or fully wrong. What can be said from the available evidence: Taiwan is at higher risk than at any point in the last forty years; the risk is more about pressure short of war than about war itself; the consequences of any major event would be globally severe; and the room for skilful diplomacy and credible deterrence to prevent a crisis is still substantial - but is shrinking, not growing.
What this means for you
For most readers, the Taiwan question is not a daily concern. It does, however, sit underneath the value of investments, the price and availability of nearly every electronic device, the security of supply chains many businesses depend on, and the stability of the part of the world economy that touches the chip industry. Some practical observations:
If you depend on chips at work
This includes anyone in technology, automotive, medical devices, defence, aerospace, advanced manufacturing, and most physical-product businesses. The risk of a chip supply disruption is now a real input to capital planning rather than a low-probability tail. Companies that have done multi-source planning, kept some inventory buffer, and avoided single-foundry exposure on critical products are the ones positioned to ride through any disruption rather than be blindsided by it.
If you invest
A single-event risk of this scale is hard to hedge directly. Diversified global portfolios already partially absorb it. Concentrated bets on Taiwanese companies, Chinese stocks tied to mainland-Taiwan tension, or single-name semiconductor exposures carry more risk than the headline suggests. Companies building chip-fabrication capacity outside Taiwan (TSMC's Arizona facilities, Intel's foundry effort, Korean and Japanese expansions, European projects) have structural tailwinds for the next decade. None of this is investment advice. It is observing where the policy gradient and the security calculation point.
If you live in the region
Japan, South Korea, the Philippines, Australia, and a number of Southeast Asian countries are now visibly preparing for a more contested Asia-Pacific. Defence spending is rising. Alliance structures are tightening. Visa and immigration policies are shifting around technology workers. If you live in one of these countries, your government is making decisions now whose effects will be felt over decades; voting on the merits and watching what is actually committed to is more useful than reacting to the news cycle.
If you live anywhere else
The economic shock from a serious Taiwan crisis would be felt globally - in chip prices, in technology product availability, in defence spending, in stock-market volatility, and possibly in oil prices and shipping. There is no part of the world economy that fully escapes a Taiwan event. The good news is that this is one of the things diversified investing and a steady cash buffer were designed for. The bad news is that Western politics has under-invested in preparing the public for the possibility that a major shock could come from this direction.
If you're thinking about supply-chain risk
Taiwan is the headline chokepoint, but the broader lesson is that the modern economy contains a number of less-visible single points of failure - the Dutch lithography company, Korean memory makers, Strait of Hormuz oil shipments, key undersea cables, a handful of pharmaceutical-ingredient suppliers, and a long list of others. Mapping where your own business or country's economy has hidden chokepoints is one of the most useful exercises a careful planner can do once a year. The lesson of Taiwan is not to obsess about Taiwan. It is to take chokepoint risk seriously generally.
The mechanics behind this
The Taiwan question sits on top of three deeper mechanisms that show up across this site. If the analysis above depends on ideas you want to understand first, these fundamentals make the conversation more legible:
