The Era Shift: Why Infrastructure, Commodities and Sovereignty Could Define the Next Investment Cycle
Why this is not just another thematic investing cycle
Most investment themes are temporary. They appear when capital markets become excited about a new technology, a new policy, or a new consumer trend. They can be powerful, but they often fade once valuations catch up or the economic story becomes too widely understood. 'This is different'
The themes discussed in this article are not simply about artificial intelligence, electric vehicles, commodities, or defence. They are about a deeper change in the structure of the global economy. The world is moving away from a thirty-year period defined by globalisation, cheap energy, low inflation, deep labour pools and just-in-time supply chains. It is moving into a period defined by geopolitical rivalry, ageing populations, energy security, resource competition, industrial policy and the physical constraints of electrification.
That is the core of the “era shift”.
From the early 1990s through to the late 2010s, the dominant economic logic was efficiency. Companies moved production to the lowest-cost jurisdiction. Governments assumed that trade integration would reduce geopolitical risk. Central banks operated in a world where inflation was largely contained. Consumers benefited from cheap goods, and investors rewarded asset-light business models. That model has been breaking down for several years.
The US-China trade war that escalated in 2018 was one of the first clear signs that globalisation was becoming politicised. The Covid-19 pandemic in 2020 exposed how fragile just-in-time supply chains could be. Russia’s full-scale invasion of Ukraine in February 2022 revealed that energy, food and fertiliser were not simply commodities; they were instruments of national power. In August 2022, the United States signed the CHIPS and Science Act, marking a major return of industrial policy. In October 2022, the US imposed sweeping semiconductor export controls on China, confirming that technology itself had become a strategic battleground. Then, in November 2022, ChatGPT brought artificial intelligence into the mainstream, triggering a global race for compute capacity, data centres and electricity.
Taken together, these events changed the investment landscape.
The question is: which assets, supply chains and infrastructure systems become indispensable in a more fragmented, electrified and resource-constrained world?
The political rationale: the return of state-led capitalism
For most of the post-Cold War era, Western economic policy was built around open markets. Governments generally trusted the private sector to allocate capital, source goods globally and optimise supply chains. That approach worked well when geopolitics was relatively stable and when the world’s major powers were willing to trade with each other on broadly predictable terms. The US-China relationship has changed that assumption.
The turning point was not one single event, but a sequence of policy escalations. In 2018, the United States imposed Section 301 tariffs on Chinese imports, arguing that China’s technology transfer practices, intellectual property policies and industrial strategy were unfair to American companies. This was not just a trade dispute about tariffs. It was an early sign that the world’s two largest economies were entering a strategic competition over manufacturing, technology and economic influence.
That competition intensified in 2022. The CHIPS and Science Act, signed in August 2022, committed the US to rebuilding domestic semiconductor capacity. Two months later, in October 2022, the US introduced major export controls designed to restrict China’s access to advanced chips and semiconductor manufacturing equipment. This effectively turned high-end semiconductors into a national security asset.
China has responded in kind. It has used its control over critical mineral processing and rare earth supply chains as leverage. The warning signs were visible as far back as 2010, when tensions between China and Japan around the Senkaku/Diaoyu islands were followed by disruption to rare earth exports to Japan. More recently, China introduced export controls on gallium, germanium and graphite in 2023 and 2024, before expanding controls in 2025 to medium and heavy rare earths such as dysprosium and terbium, which are essential for high-performance magnets.
This is the political rationale behind rare earths, permanent magnets, semiconductors, data centres, defence, grid infrastructure and critical minerals.
These are no longer ordinary industrial inputs. They are strategic assets. Governments now care about who owns them, who processes them, who transports them and who can restrict access to them. That is why the European Union introduced the Critical Raw Materials Act, setting 2030 targets for domestic extraction, processing and recycling. It is also why the EU’s Net-Zero Industry Act aims to increase European clean technology manufacturing capacity.
This matters for investors because state policy can change the economics of entire industries. Subsidies, tax credits, permitting reform, export controls, procurement contracts and strategic stockpiles can all redirect capital flows. In the old world, the cheapest supplier often won. In the new world, the politically reliable supplier may win, even if it is more expensive.
The economic rationale: efficiency is being replaced by resilience
The economic logic of the last three decades was built around efficiency. Companies wanted lower inventories, cheaper labour, lower input costs and global supply chains. This created enormous benefits, but it also created hidden fragility.
The pandemic exposed this first. Shortages of semiconductors, shipping capacity, medical equipment and basic industrial inputs showed that lean supply chains were efficient only in stable conditions. Once the system was stressed, companies discovered that they had optimised away resilience.
Russia’s invasion of Ukraine in 2022 exposed the same weakness in energy and food. Europe had built a major dependency on Russian gas. Global agriculture was exposed to Russian and Ukrainian grain exports, as well as Russian and Belarusian fertiliser supply. When the war began, energy prices surged, fertiliser prices jumped and food security became a political issue across both developed and emerging markets.
This is why I think investors need to focus more on bottlenecks.
The best opportunities may not always be in the end product. They may sit in the infrastructure, materials and enabling assets that allow the end product to exist. Artificial intelligence is the best example. Most public market attention goes to software companies, chip designers and large technology platforms. But AI is not purely digital. It requires data centres, grid connections, cooling systems, backup power, high-voltage equipment, copper, water and increasingly dedicated energy supply. This is where the economic rationale becomes powerful.
If demand for AI computing grows faster than the supply of electricity connections, then the bottleneck is not the AI model. The bottleneck is power. If data centre demand grows faster than grid capacity, then transformers, switchgear, cables and transmission assets become strategically important. If electrification increases copper demand while new mine supply remains slow and difficult to permit, then copper becomes a structural constraint. If rare earth processing remains concentrated in China, then permanent magnets become a geopolitical choke point.
This is the “picks and shovels” logic, but applied to the next economic era. The companies building the most visible technology may not be the only winners. The more durable opportunities may come from owning the assets that everyone else needs, regardless of which technology platform wins.
Demographic drivers: the world is getting older, tighter and more expensive to run
Demographics are one of the most underappreciated forces in investing because they move slowly. They do not create daily headlines, but they shape labour markets, government spending, consumption patterns and productivity over decades.
The developed world is ageing. Fertility rates have fallen across Europe, Japan, South Korea and China. Working-age populations are under pressure. Healthcare and pension costs are rising. In many economies, labour is likely to become scarcer and more expensive.
This matters because it changes the investment case for automation, robotics and artificial intelligence. AI is often discussed as if it is simply a technological breakthrough. It is also a demographic response. If economies cannot rely on ever-growing workforces, they need productivity-enhancing tools. Automation becomes less of a choice and more of a necessity.
This is particularly relevant in manufacturing, logistics, healthcare, agriculture and defence. Ageing societies will need more care workers, more medical capacity and more productivity from a smaller labour base. At the same time, reshoring and friend-shoring require higher-cost countries to rebuild industrial capacity. That only works if automation offsets labour cost disadvantages.
This is why robotics sits within the era shift theme. It is not just about exciting humanoid robots or factory automation. It is about the economic need to produce more with fewer workers.
The same demographic logic supports healthcare infrastructure, diagnostics, medical devices and surgical robotics. An older population consumes more healthcare, requires more monitoring and places greater strain on public systems. Investors should not see ageing only as a social challenge. It is also a long-term capital allocation theme.
1. Electricity grids: the foundation of the next economy
Electricity grids are my highest conviction era shift theme because nearly every other theme depends on them. The energy transition requires electricity. Artificial intelligence requires electricity. Electric vehicles require electricity. Heat pumps require electricity. Industrial automation requires electricity. Semiconductor fabrication requires electricity. Even water infrastructure, such as desalination and treatment, depends on reliable power.
The problem is that grids were not designed for this world.
For decades, electricity demand in many developed markets was relatively stable. Grid investment was often treated as a dull utility issue. That has changed. The rise of renewables requires more transmission because generation is increasingly located far from demand centres. The rise of data centres creates large, concentrated loads in specific regions. Electrification adds new demand from transport, heating and industry.
The result is a physical bottleneck.
This is why grid infrastructure is not just a climate theme. It is an economic security theme. Countries that cannot connect new generation, new factories and new data centres will lose investment. Regions with faster permitting, stronger grids and better power availability will attract capital.
For investors, the opportunity is not limited to regulated utilities. It extends to transformers, cables, switchgear, grid software, power electronics, engineering services and companies exposed to transmission capex.
The key point is simple: there is no AI revolution, no energy transition and no reshoring boom without the grid.
2. Copper: the metal behind electrification
Copper is one of the clearest examples of a boring asset becoming strategically important. It is essential because it conducts electricity efficiently and is difficult to substitute at scale. The more the world electrifies, the more copper it needs. Electric vehicles use more copper than internal combustion vehicles. Renewable energy systems require copper. Data centres require copper-heavy power distribution. Transmission networks require copper. Industrial automation requires copper.
The economic rationale is supply-demand imbalance.
Demand is being pulled higher by multiple structural trends at the same time, while new copper supply is difficult to bring online. Large mines take years to permit, finance and develop. Ore grades in some mature mining regions have declined. Political risk is significant because copper production is concentrated in a relatively small number of countries.
That creates the potential for a long-cycle commodity thesis.
Copper is not attractive simply because “green energy needs copper”. That is too shallow. Copper is attractive because it sits at the intersection of electrification, grid expansion, industrial policy and supply constraints. In other words, copper is not just a commodity. It is a measure of how physically possible the energy transition really is.
3. Data centres: AI’s physical infrastructure layer
Artificial intelligence looks digital, but its economics are increasingly physical. The launch of ChatGPT in November 2022 was a major turning point because it moved generative AI from research labs into mainstream public and corporate use. Since then, the largest technology companies have entered a compute arms race. The result has been a surge in demand for data centres, chips, cooling systems and power. This is where many investors misunderstand the theme. AI is not only about models and applications. It is about infrastructure.
A data centre requires land, grid access, fibre connectivity, cooling, backup power, security, water and long-term energy procurement. The most valuable sites are not simply those with cheap land. They are the sites with reliable power, low latency, planning approval and access to major connectivity routes.
That is why data centres increasingly resemble strategic infrastructure. Governments care where they are located. Corporates care whether they can secure capacity. Utilities care whether local grids can handle the load. Communities care about water use, electricity prices and land use.
This creates several investment angles. Data centre REITs are one route, but the broader opportunity includes cooling technology, electrical equipment, backup power, fibre networks, substations and grid interconnection services.
The deeper thesis is that compute is becoming a factor of production. Just as factories needed electricity in the twentieth century, modern companies will need compute capacity in the twenty-first.
4. Subsea cables: the hidden highways of globalisation 2.0
Subsea cables are one of the most important yet least understood pieces of global infrastructure. They carry the overwhelming majority of intercontinental data traffic. Financial markets, cloud computing, military communications, digital trade and consumer internet services all rely on them. Without subsea cables, the global digital economy does not function.
The political rationale has become much clearer in recent years. As geopolitical tensions rise, countries increasingly view data infrastructure as a national security asset. Cable routes, landing stations and repair capacity matter because they determine the resilience of digital communications.
This is especially important in a world where data is strategic. AI training, cloud services, financial transactions and government communications all depend on secure and fast data movement.
The investment opportunity is more niche than data centres, but the theme is powerful. Cable manufacturers, cable-laying vessels, maintenance providers, network operators and landing station infrastructure all sit within the broader digital infrastructure ecosystem.
The key point is that the internet is not “in the cloud”. It is on the seabed.
5. Rare earth magnets: the clean energy choke point
Rare earth magnets are one of the most important strategic bottlenecks in the global economy. Permanent magnets are used in electric vehicle motors, wind turbines, robotics, industrial automation, defence systems and advanced electronics. The most important magnet rare earths include neodymium, praseodymium, dysprosium and terbium.
The critical issue is not simply mining. It is processing, refining and magnet manufacturing. China has built a dominant position across these stages over decades. This did not happen by accident. It reflects long-term industrial policy, scale, environmental tolerance, technical expertise and downstream manufacturing integration. The political risk is that China’s control over rare earth supply chains gives it leverage in moments of geopolitical tension. The 2010 China-Japan dispute showed how rare earth supply could become a diplomatic pressure point. The later US-China technology conflict showed the same logic at a larger scale. As the US restricted China’s access to advanced semiconductors, China responded by tightening controls on critical minerals.
This creates a clear investment rationale. Western governments want alternative supply chains, but building them is difficult. Rare earth processing is technically complex, environmentally challenging and capital intensive. That means non-Chinese producers, processors and magnet manufacturers may become strategically valuable, even if they are not the lowest-cost producers.
The investment theme is not “rare earths are scarce”. The better thesis is: rare earth supply chains are politically fragile, strategically essential and difficult to replicate.
6. Nuclear energy and uranium: baseload power returns
Nuclear energy is returning because the energy transition has collided with reality.
For years, many countries focused on renewables while underestimating the importance of reliable baseload power. Wind and solar are essential, but they are intermittent. Battery storage helps, but it does not fully solve the problem of industrial-scale, round-the-clock power demand.
AI has strengthened the nuclear argument. Data centres need reliable electricity. Semiconductor fabs need reliable electricity. Electrified industrial systems need reliable electricity. If countries want decarbonisation and energy security at the same time, nuclear becomes harder to ignore.
The political context changed significantly after Russia’s invasion of Ukraine in 2022. Europe’s energy crisis forced governments to reconsider energy security. Dependence on imported fossil fuels became a strategic vulnerability. At the same time, climate targets remained in place. Nuclear sits at the intersection of those two priorities: low-carbon power and domestic energy security.
For investors, the nuclear theme includes uranium mining, enrichment, fuel services, reactor technology, engineering, maintenance and utilities with nuclear exposure. The uranium market is especially interesting because supply has historically been cyclical and underinvested, while demand visibility may improve if nuclear policy support strengthens.
The deeper point is that the world wants more electricity, cleaner electricity and more secure electricity. Nuclear is one of the few technologies that can address all three.
7. Water infrastructure: the climate adaptation asset class
Water is often discussed as a social or environmental issue, but it is also an investment theme. Climate change is making water availability less predictable. Some regions face drought, others face flooding, and many cities are dealing with ageing water systems. At the same time, industrial demand for water is increasing. Data centres need cooling. Semiconductor plants require ultra-pure water. Agriculture remains heavily water-dependent. Urbanisation increases pressure on treatment and distribution networks.
This makes water infrastructure a long-duration capital investment theme. The opportunity includes water utilities, desalination, filtration, leak detection, wastewater treatment, smart metering and industrial water management. The investment rationale is not based on speculative growth. It is based on necessity. The politics are also important. Water scarcity can create social tension quickly. Unlike many other infrastructure problems, water failures are immediately visible to households, farmers and local communities. That makes governments more likely to intervene, regulate, subsidise and invest. Water is therefore both a climate adaptation theme and a national resilience theme.
8. Food security and fertilisers: agriculture becomes geopolitical
Food security moved back onto the political agenda in 2022. When Russia invaded Ukraine, the world was reminded that grain, fertiliser and energy markets are deeply connected. Russia and Ukraine were major agricultural exporters. Russia and Belarus were important to fertiliser supply. Natural gas is a key input for nitrogen fertiliser production. When energy and fertiliser prices rose, the cost of food production increased.
This matters because food inflation is politically explosive. In developed markets, it pressures consumers and central banks. In emerging markets, it can create instability. Governments therefore care deeply about fertiliser access, domestic agricultural productivity and food supply chains. The long-term investment rationale is supported by several forces: population growth in some regions, climate stress, soil degradation, water scarcity and the need to produce more food from limited land. Fertilisers remain essential to crop yields. Precision agriculture, irrigation, seed technology and farm automation also become important because they help improve productivity.
This is not simply an agriculture theme. It is a food security theme. The strongest opportunities are likely to sit where agricultural productivity, input security and climate resilience overlap.
9. Defence industrial capacity: the end of the peace dividend
For much of the post-Cold War period, Western defence spending was shaped by the assumption that large-scale conventional conflict was unlikely. That assumption has weakened.
Russia’s annexation of Crimea in 2014 was an early warning. The full-scale invasion of Ukraine in February 2022 was the turning point. It revealed that ammunition stockpiles, air defence systems, drones, missiles, artillery shells and industrial production capacity were insufficient for a prolonged conflict.
The investment rationale is not simply that governments will buy more weapons. It is that defence industrial capacity needs to be rebuilt after years of underinvestment.
Modern defence depends on complex supply chains. It requires electronics, sensors, propulsion systems, rare earth magnets, secure communications, satellite infrastructure, precision engineering and advanced materials. Many of these supply chains overlap with civilian technologies such as semiconductors, robotics and aerospace.
This makes defence a broader industrial resilience theme.
Governments are now more willing to sign long-term procurement contracts, support domestic production and treat defence manufacturing as strategic infrastructure. That creates visibility for certain suppliers, although investors must remain mindful of valuation, political risk and ethical constraints. The core thesis is that the peace dividend is fading. Security is becoming a larger and more persistent part of public spending.
10. Gold: monetary insurance in a fragmented world
Gold is not a productive asset in the conventional sense. It does not generate cash flows. That is precisely why many investors dismiss it. But gold has a different role. It is a monetary and geopolitical hedge.
The case for gold strengthened after 2022. When Western governments froze a large portion of Russia’s foreign exchange reserves following the invasion of Ukraine, reserve managers around the world took notice. The lesson was not that the US dollar would suddenly collapse. That is too simplistic. The lesson was that foreign exchange reserves held within another country’s financial system can carry political risk.
For central banks, especially in emerging markets, gold offers an asset that is no one else’s liability. It cannot be sanctioned in the same way as bank deposits or government bonds held through Western financial infrastructure, provided it is stored domestically or in a trusted jurisdiction. This helps explain why central bank gold buying has remained strong. It reflects a broader desire for reserve diversification in a more fragmented geopolitical environment.
Gold should therefore be understood less as a “fear trade” and more as a strategic reserve asset. In a world of high debt, geopolitical rivalry and monetary uncertainty, its role becomes more relevant.
My highest conviction themes are not based on what is fashionable. They are based on where I see the strongest overlap between political necessity, economic demand and structural supply constraints.
The first tier is foundational infrastructure: electricity grids, copper and data centres. These sit at the centre of the new economy because almost every other trend depends on them.
The second tier is strategic bottlenecks: rare earth magnets, nuclear energy, uranium, water infrastructure and subsea cables. These are areas where demand is structurally important but supply chains are complex, concentrated or politically sensitive.
The third tier is sovereignty and resilience: defence industrial capacity, food security and fertilisers. These themes are supported by government policy because they relate directly to national security and social stability.
The fourth tier is demographic adaptation: robotics, automation and healthcare capacity. These themes address the economic consequences of ageing populations and labour scarcity.
The fifth tier is portfolio insurance: gold. It benefits from a world in which monetary systems remain functional but geopolitical trust is lower than before.
The common thread is that these themes are not consumer preferences. They are operating requirements for the next economy. The world can postpone discretionary spending. It cannot function without electricity, food, water, compute power, secure communications, strategic minerals, defence capacity and monetary trust.
That is why these are not ordinary themes. They are era shift themes.
