Superpowers, Supply Chains and the Next Tech Cycle

Herald — Opening

Good evening, and welcome to the fourth Hergemony Hour.

I'm Herald. Each month, Hergemony steps back from the daily news cycle to examine how changes across Earth, people, politics and capital connect.

July asked when strategic importance becomes investable value. August examined the physical infrastructure beneath technological growth. September followed energy and the cost of capital.

October brings those threads together through two questions.

First: as the United States and China compete across trade, technology and strategic supply chains, is the global economy becoming structurally more fragmented?

Second: as artificial intelligence moves deeper into the physical economy, what determines the next technology cycle — chips alone, or the entire system of power, minerals, manufacturing and capital beneath them?

Our October question is: can the global economy stay connected in a multi-block world?

Topic One: U.S.–China — A More Fragmented World

The relationship between the United States and China remains one of the central organising forces in the global economy.

Recent negotiations show that competition and engagement can coexist. Washington and Beijing have continued trade talks and opened channels for dialogue on artificial intelligence, while strategic restrictions and investigations remain part of the relationship.

Fragmentation does not necessarily mean complete separation. A more plausible pattern is selective interdependence: trade continues in many ordinary goods while governments place tighter controls around technologies, infrastructure and inputs they consider strategically sensitive.

Semiconductors are an obvious example. Advanced computing capability has become an economic asset, an industrial capability and a national-security concern at the same time.

Critical minerals reveal the other side of the same system. Advanced chips, electric systems, aerospace equipment and defence technologies depend on physical inputs whose extraction, processing and refining are geographically concentrated.

A country does not need to dominate every stage of a technology to influence the system. Control over one difficult-to-replace chokepoint can matter enormously.

The question is shifting from where something can be produced most cheaply toward where it can be produced reliably, securely and at acceptable strategic risk.

Redundant factories, alternative suppliers, strategic inventories and domestic capacity may improve resilience, but they also cost money. Efficiency and resilience are no longer always the same objective.

The Multi-Block Economy

It is tempting to describe the emerging world as two clean blocs. Reality is more complicated.

Many middle powers trade extensively with China, rely on security relationships with the United States, seek investment from both, and want to preserve room for independent policy.

The future may therefore be less a simple division into two camps and more a network of overlapping partnerships.

For Hergemony, the key question is which relationships govern access to technology, energy, minerals, ports, finance, data and industrial capacity. Those networks determine where geopolitical pressure can become economic pressure.

Topic Two: The Next Tech Cycle

Our second topic begins with artificial intelligence, but it does not end there.

The first phase of the AI investment story was dominated by models, software and advanced processors. The next phase increasingly exposes the physical system underneath computation.

AI requires semiconductors. Semiconductor production requires specialised equipment, materials, water, energy and complex manufacturing networks.

Data centres require electricity, transformers, cooling, networking equipment and land. Expanding electricity supply requires grids, generation, storage and financing. Many of those systems depend in turn on copper, rare earths and other strategic materials.

This creates an investment chain rather than a single technology theme. The question becomes: where does economic value accumulate along that chain?

Strong demand for AI hardware can benefit chip designers and memory producers, but bottlenecks may move elsewhere as the cycle matures.

If power becomes scarce, electricity and grid infrastructure matter more. If specialised components become scarce, equipment suppliers gain strategic importance. If mineral access becomes constrained, upstream processing and alternative supply chains become more valuable.

The next technology cycle may therefore be defined by convergence: digital technology meeting the physical economy.

Earth, People, Politics and Capital

October gives us a useful way to apply Hergemony's four-domain framework.

Earth provides the energy and material inputs: electricity, land, water and minerals.

People create, operate and ultimately use the technologies, while automation and productivity affect labour and society.

Politics determines trade rules, industrial policy, export controls, alliances and strategic access.

Capital determines which projects are financed, what return investors require and which companies can turn strategic importance into durable economic value.

The technology cycle therefore cannot be understood through technology alone.

Ten Minutes to Markets

The first signal is semiconductors. Demand for AI-related computing remains an important measure of the cycle, but investors should distinguish genuine end demand from inventory accumulation and expectations already embedded in valuations.

The second signal is power infrastructure. Watch electricity demand, grid constraints, transformers, cooling systems and the capital expenditure required to connect new data centres.

The third signal is critical minerals. Watch export restrictions, processing capacity, strategic stockpiles and efforts to diversify supply.

The fourth signal is trade policy. Tariffs, export controls and industrial subsidies can alter company economics quickly, particularly when supply chains cross several jurisdictions.

The fifth signal is the cost of capital. September's lesson remains relevant: even strategically important infrastructure must be financed.

For Hergemony Capital, this means moving beyond the label AI and mapping the complete value chain: compute, memory, networking, electricity, grid equipment, cooling, minerals, manufacturing and financing.

What Would Confirm the October Thesis?

The fragmentation thesis would strengthen if strategic trade restrictions broaden, governments accelerate domestic or allied manufacturing, critical-mineral diversification receives more capital, and companies increasingly redesign supply chains around geopolitical risk rather than cost alone.

The technology-cycle thesis would strengthen if AI capital expenditure continues to expand while bottlenecks migrate from processors toward memory, electricity, grid equipment, cooling and other physical infrastructure.

We would also look for evidence that these constraints translate into durable pricing power or stronger cash flows for specific companies rather than simply higher industry spending.

What Would Weaken the Thesis?

The fragmentation thesis would weaken if U.S.–China economic relations move toward durable liberalisation, strategic restrictions narrow materially and companies reverse supply-chain diversification because geopolitical constraints cease to affect operating decisions.

The technology-cycle thesis would weaken if AI demand slows sharply, utilisation disappoints, capital expenditure falls, or infrastructure investment fails to produce adequate economic returns.

Hergemony should not confuse an important technology with an automatically attractive investment. The objective is to identify the transmission mechanism and then test it.

Forward Look

Watch the next phase of U.S.–China trade negotiations.

Watch semiconductor and advanced-technology restrictions.

Watch rare earths and other critical-mineral supply chains.

Watch AI capital expenditure and memory demand.

Watch electricity prices, grid investment and data-centre power constraints.

Watch long-term bond yields and the financing conditions beneath the infrastructure cycle.

And watch the middle powers. Their decisions may reveal whether the emerging global system becomes divided into rigid blocs or remains connected through overlapping networks.

Closing

July taught us to distinguish strategic importance from investable value.

August showed that technological growth rests on physical infrastructure.

September showed that infrastructure rests on energy and capital.

October adds another layer: those systems now operate inside an increasingly strategic global network.

Technology depends on supply chains. Supply chains depend on politics. Politics interacts with resources. And every part of the system ultimately requires capital.

That is why Hergemony studies Earth, people, politics and capital together.

The October question remains open: can the global economy stay connected in a multi-block world?

I'm Herald. Thank you for listening to the October edition of The Hergemony Hour.

Good evening.
