A Semiconductor Fell on and Broke My House
A thought experiment in enmeshedness. On semiconductors, geopolitical fault lines, and why your home's value is controlled by forces further away than you think.
There are two ways a home gets its price. The first is mass psychology; what your neighbours think their homes are worth, what their neighbours think, what their neighbours' neighbours think, rippling outward through a neighbourhood, a community, a region, a city. Until the aggregate of those sentiments, expressed through votes and transactions and the opinions formed between them and produces a “market price“. That part is covered elsewhere in this series.
This essay is concerned with the other part. The ecosystem within which all of that psychology operates. The macroeconomic state of affairs that sets the terms under which sentiment gets expressed and capital gets deployed. Therefore, this is an informal essay about the stochastic, and the plight of the short-sighted.
It is also a thought experiment. Not designed to get you to open a Polymarket account. Designed to show you something about the enmeshedness of the world your assets live in, and the alternate lives they lead outside of their localities.
START WITH THE SEMICONDUCTOR
Play along for a moment. Take the modern semiconductor: a sliver of engineered silicon, smaller than a fingernail, operating at dimensions measured in nanometres. Now try to identify a single significant system of modern technological or operational life that doesn't depend on one.
Smartphones. Data centres. Electric vehicles. Medical imaging equipment. Financial trading infrastructure. Weapons systems. The logistics networks that move goods across continents. The payment rails that process transactions. The grid management systems that keep cities powered. Every one of these either contains a semiconductor or depends on systems that do. The more you trace the dependencies, the more the modern world starts to look like a single, extraordinarily complex organism with one circulatory system.
That circulatory system is manufactured by a surprisingly small number of companies. The cutting-edge chips — the ones powering AI systems, high-performance computing, advanced defence applications, and next-generation smartphones — are produced at meaningful scale by select fabs (fabrication plants) globally. TSMC, headquartered in Taiwan, produces anywhere between 40% - 90% (on some accounts, depending what you mean) of the world's most sophisticated semiconductors. One company. One island. The supply chain upon which the operational infrastructure of the modern world depends is concentrated in a geography that is, at this moment, the subject of one of the most consequential geopolitical disputes on earth
THE FAULT LINE
China's position on Taiwan is not ambiguous and has not changed. The question of whether, when, and how that position gets acted upon is one that occupies significant bandwidth across defence establishments, intelligence agencies, and economic planning bodies in every major economy. The reason is not abstract solidarity with a democratic island. The reason is the fab.
Estimates of the economic damage from a disruption to TSMC's production capacity vary, but the directional consensus is severe. Some modelling suggests a scenario involving military intervention and production shutdown could contract global GDP by figures that make the 2008 financial crisis look contained. The reason is the dependency chain; every industry that runs on advanced semiconductors would face supply collapse simultaneously, with no meaningful short-term substitute. The expertise and capital required to build a competing, integrated production & design ecosystem would take long years and hundreds of billions of dollars — still hasn't been achieved by any country attempting it.
Production disruption
Military intervention interrupts or destroys TSMC's manufacturing capacity. Advanced chip supply collapses globally. No short-term substitute exists at equivalent process nodes.
Technology sector seizure
AI infrastructure, cloud computing, consumer electronics, defence systems, all face simultaneous supply shock. Major technology companies lose the input that drives their revenue. Market capitalizations collapse.
Capital flight and credit contraction
Equity markets reprice downward across sectors. Credit conditions tighten. Central banks face a stagflationary scenario — supply shock inflation alongside demand collapse — with limited conventional tools.
Canadian exposure
Canada's economy is deeply integrated with US capital markets, technology sector activity, and global trade flows. A severe global contraction hits Canadian GDP, employment, and business confidence simultaneously. The foreign capital inflows that have historically supported Canadian real estate prices reverse.
The home
Demand collapses. Credit availability contracts sharply. The psychological layer — the mass sentiment that forms the first tier of real estate valuation — turns negative across the board. The price of a home in Toronto is now a function of a geopolitical event in the Taiwan Strait.
THE THOUGHT EXPERIMENT, COMPRESSED
A semiconductor the size of a fingernail, manufactured in a facility on an island 12,000 kilometres from Toronto, subject to a territorial dispute between two nuclear-capable states, sits at the base of a dependency chain that runs through every major technology system, through global capital markets, through Canadian GDP, through employment and credit conditions, through buyer sentiment, through comparable sales, and through — quietly, invisibly — the number your home transacts for.
The chain of events designed to show you how far the roots of a local asset actually reach.
WHAT TO DO WITH THIS
The point of this thought experiment is not prediction. The Taiwan scenario may never materialize. The chip supply chain may diversify meaningfully over the next decade. The geopolitical situation may stabilize. Any of these outcomes is possible, and none of them is certain.
The point is the enmeshedness itself, which generalizes beyond semiconductors and fab plants. The fact that such chains exist — that they are traceable, that they are real, that they operate whether or not you are aware of it — changes your orientation as a serious long-term thinker with local assets.
Treating Canadian real estate as a sealed system, responsive only to local supply and demand and the sentiment of nearby buyers, is not just analytically incomplete. It is a categorical error. The asset is local. The forces that price it are not. The bead on the abacus sits in your neighbourhood. The hands moving it are everywhere else.
