The United States just crossed an historic line by sending its military to Venezuela in order to capture the president of a nation that is sovereign.
The message, no matter what one may think of Nicolas Maduro was clear. The new political landscape in the Western Hemisphere is shaped by power, not protocol. And the whole world is watching.
The precedents are spread quickly.
What stops Beijing from using the same logic in the Taiwan Strait if Washington is able to justify an “aggressive” strike as a way of “resolving” a problem?
A move framed as security, sovereignty, or inevitability–executed not in the shadows, but in full view of the global order.
Imagine a geopolitical flashpoint that could wipe out decades of economic progress in the world overnight.
An invasion by China of Taiwan could unleash the worst economic shock in modern history.
Bloomberg estimates that the world economy may lose as much as $10 trillion dollars in its first year, which is far more than the damages caused by the financial crisis of 2008 or COVID-19.
Taiwan is the only country in the world that has the most advanced manufacturing capability of semiconductors, the tiny motors powering electric cars, smartphones and artificial intelligence data centres.
The AI-driven stock market rally, which has driven the S&P 500 index to new highs, would most likely crash if those fabs went offline.
Taiwan’s grip on AI chips
You need to know one thing: Taiwan Semiconductor Manufacturing Company (TSMC) makes the majority of advanced chips in the world.
TSMC produces over 75% all AI chips that are driving the artificial intelligence boom.
TSMC is the company that Apple uses to design its iPhone processors. TSMC is the company that Nvidia uses to build graphics chips for AI data centres.
When Google develops customized chips for its AI Infrastructure, they go to TSMC.
It’s not just a chip company anymore; the AI industry is now based on the chips.
Joshua Mahony is Chief Market Analyst for Scope Markets and he makes it clear when addressing .
Apple and Nvidia rely heavily on TSMC to manufacture their chips, so the loss of this huge portion of the supply chain would be devastating for their production and revenue.
It is an unprecedented concentration of production capacity on a single, island-nation.
Taiwan’s dominance in modern economies is just as important as was oil during the 20th Century. A disruption would not only slow down production. The production would be completely stopped.
Low probability of catastrophic impacts paradox
Expert analysis indicates that a military invasion is unlikely to occur in the near future, despite the existential damage.
Dr. Arun Pocumpally is a JSW Science and Technology fellow at the Asia Society Policy Institute.
At least for the next five years, China will not invade Taiwan or annex Taiwan forcefully.
Why do geopolitical risks continue to scare investors? Answer lies in the financial probability theory.
You hedge when the downside will be catastrophic but the upside has been capped.
Investors who are sophisticated don’t just wait until the probability of invasion reaches 50% to protect themselves.
Even when the odds are low, they price in tail risks, or extreme events.
It creates an odd market dynamics.
AI-related stocks are soaring on the back of investor enthusiasm. Investors are buying insurance to protect themselves against the chaos in Taiwan. Markets are not irrational. The market is always braced to crash.
The AI bubble: concentration risk at steroids
This current Tech rally is impressive but fragile.
NVIDIA (NVIDIA), Microsoft (Google), Apple, Meta (Amazon), and Tesla have been the “magnificent seven” companies that has driven most of S&P 500 gains.
Nvidia alone has a market value of nearly $4.6 trillion and a huge influence on the direction of the market.
This rally’s profitability chain is circular and reinforces itself.
Microsoft purchases GPU chips from Nvidia for its AI services.
Microsoft receives revenue from these services. Google also does this. Apple sells TSMC-made chips to AI data centers. This is a mutually dependent closed cycle.
If you break that loop, the whole structure will collapse. An invasion of Taiwan would achieve this.
Mahony explains:
Profitability and earnings are likely to be revised down if there is a Chinese invasion.
BCA Research’s models predict a S&P500 crash of 40% in the event of a complete military conflict.
In blockade scenarios, expect 10% declines. This is not a prediction from a doomsayer. These are credible financial models.
Numbers behind nightmare
It is difficult to comprehend the extent of damage. In an invasion scenario, global economic output would shrink by 10.2% and in a blocking scenario it would fall by 5%.
In order to put this into perspective, the global GDP declined by around 5% in 2008 during the financial crisis.
According to IEP’s estimates, Taiwanese economy will contract by 40% within the first year.
Bloomberg’s report indicates that China could experience a contraction of 16.7% to 8,9%, depending on which scenario is used. In the United States, GDP would decline by 6.7% to 3.3%.
This is not a theoretical concept. These are real jobs lost, business closures, and supply chain halts in every major industry.
Chips from Taiwan are used in the manufacture of consumer electronics, mobile phones, medical devices, automotive manufacturing and more.
Only the Taiwan Strait handles half of all container traffic. A blockade of any kind would stifle trade valued at over $3 trillion per year.
A medium-term Reality Check
Here, Dr. Polcumpally brings a sense of realism to the market that is often overlooked. While the catastrophe is severe, it may not last forever.
If China were to annexe Taiwan by force, the market for semiconductors and the AI value chain could suffer for a few years. However, the markets would absorb these shocks and TSMC would continue manufacturing the latest chips under a new business strategy.
The markets are resilient. The supply chains are flexible. Alternative arrangements can be made with time.
It doesn’t necessarily mean that the first shock won’t be catastrophic. The world’s economy won’t be devastated for ever.
The recovery of the West depends on how much they continue to invest in alternative manufacturing technologies.
Polcumpally says that “reconfiguring business deals may take a few years, but it will not be hard.”
The homegrown advantages that domestic companies have in South Asia, Europe and the Middle East, along with their established US hyperscalers, and investments made throughout these areas, will provide resilience to Chinese competitors. This is only possible if current AI investments continue.
His emphasis. Politics matters. Recovery will stall if the US and its allies stop building chip capacities.
Reshoring is a trap
It touches on an even deeper issue. Trump’s administration pushed semiconductor manufacturers to return home through tariffs and incentives. The progress has been genuine but not complete.
Mahony describes the challenge.
Trump’s efforts to encourage companies to bring manufacturing back to the US via incentives and tariffs have a way to go until these companies can replace all their imports such as those from Taiwan.
It is a hard fact that the US cannot quickly replicate Taiwan’s production capacity to fill a gap in supply if Taiwan were to go offline.
Infrastructure is non-existent. Asia is the centre of expertise.
The Western regulations and labour costs make it nearly impossible to replicate Taiwan’s economic model.
Dr. Polcumpally explains:
It is impossible to replicate the manufacturing culture of China or Taiwan in Western countries, due to the strict labour laws and lifestyle. China may allow some outsourced semiconductor assembly and testing facilities and manufacturing to operate on US soil. However, there are questions about the long-term viability of these operations.
It’s simple: you can’t expect a chip factory worth $20 billion in Texas to perform like one in Taiwan.
The labor laws have become stricter. The costs are higher. Different regulatory frameworks.
A scenario in which Taiwan fell would result in a supply-chain vacuum lasting for years that could not be filled.
What the US, Japan and India could do
Joe Biden, the former president of the United States, broke through decades of strategic ambiguity by stating explicitly that America would militarily defend Taiwan. What does this mean in reality?
The opinions of experts are split. Others envision direct American military action, with American forces fighting Chinese troops.
Some predict an “Ukraine Model” whereby the US provides weapons and assistance but does not engage in direct combat.
Mahony draws a disturbing parallel
China may be looking to take greater control of its own hemisphere. The US’s actions in Venezuela raise many questions about the possibility of similar action in Taiwan.
It reflects a real lack of confidence in American resolve. Trump already questioned NATO’s commitments.
Responses in Asia would be wildly different.
Japan has called a Taiwan invasion a “survival-threatening situation” and would likely intervene militarily. Losing Taiwan would leave the Japanese Islands vulnerable to Chinese dominance.
South Korea is faced with a difficult choice. China is its neighbor and it depends on Chinese commerce.
A Taiwan dominated by China would threaten South Korean security. Seoul prepares for Taiwan contingencies, while avoiding provocations from Beijing.
India is still hesitant in its strategic decisions. New Delhi is unlikely to intervene directly in the Sino-Indian border dispute despite growing Taiwan relations and Quad Security Partnerships.
India’s neutrality is likely to be preferred, but a collapse of the supply chain would still have a devastating effect.
Southeast Asian countries like the Philippines could be caught up in the crossfire. The Philippines is home to US bases and could be a target of Chinese attacks if they allow American operations.
The majority of ASEAN countries would choose neutrality but suffer from economic destruction if the supply chain is disrupted.
Double bind in Chinese culture
Irony is the worst part of Taiwan invasion scenarios. Even if China wins, it still loses.
Joshua Mahony explains that Chinese rivals may initially benefit.
The Chinese tech industry could gain from increased access to technology expertise and boost their AI drive.
This ignores an important reality. TSMC is prepared to take down its equipment if it were captured. Beijing will gain control over the facilities, but won’t be able to use them. These fabs are worthless.
A Chinese invasion could also trigger sanctions and economic isolation as well as a significant contraction in China’s GDP.
The longer-term outlook of Dr. Polcumpally is sobering.
In a decade, China will dominate the ASEAN markets and the African ones.
The global economy will be divided into two competing blocs of semiconductor producers, with one centered on China and the other on the West. The trade would fragment. Divergence in innovation. Globalization would be fragmented.
The ability of Western economies to avoid this result depends on their political commitment.
Polcumpally cautions that “this is possible if current AI investments in alternate regions are not continued”. If resolve wanes, the fragmentation will become permanent.
No one talks about the employment shock
Jobs are often overlooked in the macroeconomic modeling.
Taiwan’s semiconductor sector faces a 34,000-worker shortage by May 2025.
US semiconductor workers will be in short supply by 2029. Japan faces a 40,000-worker deficit. South Korea is expecting a shortage of 56,000 workers by 2031.
The invasion of Taiwan would reverse the momentum for workforce development.
Engineers from Taiwan would leave for safer jurisdictions and permanently weaken Taiwan’s competitiveness.
Companies that manufacture semiconductors would stop hiring in all parts of the world. The unemployment rate in economies dependent on technology would rise sharply.
Silent assumption of the market
Most experts believe that a Chinese invasion of Taiwan is unlikely to happen in the next 5 years. The markets are not waiting for certainty before they experience a price crash.
The most important events in financial terms are those that are low-probability and high-impact, not because they’re expected but because you can only survive them once.
Taiwan is not the only danger. The global economy has quietly decided to concentrate its most important manufacturing capabilities in one location, which is irreplaceable. One island. One chokepoint. No redundancy.
This concentration, whether through an invasion, a blockade or cyberattacks, is like a sword hanging over the global markets. It’s visible, it’s acknowledged and yet largely ignored.
Investors who take this precaution aren’t being alarmists. Investors who hedge this risk are not being alarmist. Wall Street prices are not accurate. The AI boom that is driving record highs in equity markets rests on an unstable foundation.
The real fault-line is not the likelihood of an invasion, but the fragility. It is there.
