Semiconductors: The New Oil? A Calm Guide to the Chip Map

Every few months a headline declares that semiconductors are the new oil. It is a useful shorthand for a real strategic worry, but it flattens a supply chain that is stranger, more distributed, and in some ways more fragile than an oil market. This is a guide to the actual map, not the metaphor.

Why chip-making concentrates in so few places

Unlike oil, there is no map of chip deposits. What determines where chips get made is a combination of capital intensity, tacit knowledge, and clustering effects that reinforce each other over time.

• Capital intensity: a modern fabrication plant, or fab, can cost several billion dollars and takes years to build, so only a handful of firms and states can fund one and expect a return.
• Tacit knowledge: much of what makes a fab run at high yield is not written down in a manual. It lives in the experience of specific engineers and technicians who have spent years tuning one process line, which makes it very hard to copy quickly elsewhere.
• Yield learning curves: a new fab starts out producing a high proportion of defective chips and improves gradually through thousands of small adjustments. This learning curve resets partially whenever production moves to a new site, which discourages relocation.
• Clustering: once specialist suppliers, equipment technicians, and trained engineers gather around a handful of hubs, it becomes cheaper to build the next facility nearby than to start a new cluster from nothing. This is the same logic that concentrates other industries, discussed in geography and power.

The result is a geography that looks accidental but is actually the outcome of compounding advantages, similar to how certain maritime chokepoints became indispensable simply because trade routes kept reinforcing them rather than because no alternative route existed.

The supply chain has many stages, and each one is a different kind of bottleneck

"Chips" is not one industry. It is a chain of highly specialised stages, and concentration happens at different points for different reasons.

Notice that a country or company can be strong at one stage and largely absent from another. Being described as a chip power usually means dominance in one or two of these rows, not the whole chain.

Why the oil analogy partly works

The comparison is not baseless. Like oil in the twentieth century, chips are now a general-purpose input that touches almost every other industry, from cars to healthcare to household appliances. Disruption to supply ripples outward quickly because so many other products depend on a steady flow of chips, and stockpiles are limited because chip designs go out of date fast. Both goods have also become objects of strategic policy, with governments treating access and manufacturing capacity as matters of national resilience rather than pure commerce.

Why the analogy mostly does not work

The differences matter more than the similarities once you look closely.

• Chips are engineered, not extracted. There is no fixed underground reserve; supply depends on human skill, equipment, and investment, all of which can in principle be built up elsewhere given enough time and money.
• Substitutability grows over time. A specific oil deposit cannot be moved, but chip designs, factories, and even entire supply chains can shift location across a generation, as has happened before with other manufacturing industries.
• There is no OPEC for chips. Oil supply has at times been coordinated by a cartel of producing states; chip manufacturing is dispersed across competing private firms operating under different national policies, without a single body that sets output.
• Demand is derived, not primary. Nobody wants a chip for its own sake the way people want fuel to burn. Demand for chips reflects demand for cars, phones, appliances, and data infrastructure, so it moves with the health of dozens of other sectors rather than a single one.
• The product itself is diverse. A barrel of crude oil is a fairly uniform commodity; a memory chip, a processor, and a simple sensor chip are entirely different products with separate supply chains, priced and traded in unrelated ways.

Oil is a resource you find. A modern chip is closer to a very small, very precise building, assembled from hundreds of specialised trades that each took decades to master.

What genuine scarcity actually looks like here

When chip shortages happen, they are rarely about running out of raw material. More often they trace back to a narrow bottleneck: a single class of equipment with few manufacturers, a specific packaging step with limited capacity, or a sudden demand spike in one product category that a fab cannot retool for quickly. Understanding which stage is constrained tells you far more than a headline number about global chip output ever will.

How to read chip news calmly

1. 1Ask which stage of the chain the story is actually about. Design, equipment, fabrication, packaging, and materials each have separate bottlenecks and separate players.
2. 2Be sceptical of round, precise-sounding market share figures quoted without a source; the real picture is usually a distribution across several firms and shifts gradually rather than overnight.
3. 3Remember that new fab announcements take years to translate into shipped chips, because of the learning curve involved in reaching high yield.
4. 4Separate policy statements from production reality. Plans to build capacity are not the same as capacity coming online, and both are worth tracking as distinct facts.
5. 5Treat the whole topic as a long, slow-moving industrial story rather than a fast-moving crisis, since the underlying engineering constraints change over years, not weeks.

None of this requires a side to be taken on any current dispute, and this piece deliberately avoids naming winners or predicting outcomes.
