Overview
For four decades capital flowed into financial assets as falling interest rates, rising debt and globalisation inflated stocks, bonds and property. Today the pendulum seems to be swinging back towards the physical economy.
Gold, energy, industrial metals, agriculture, infrastructure and water all sit at the foundation of modern civilisation, and growing scarcity is forcing investors to take notice.
This article examines the possible sequence of that rotation between physical asset classes, and explores the ETFs that provide exposure to the tangible assets in those classes.
1. ROTATING FROM FINANCIAL ASSETS INTO PHYSICAL ASSETS
---
For almost four decades investors have lived through an extraordinary era of financial asset inflation.
Falling interest rates, globalisation, expanding debt, and central bank liquidity pushed capital towards stocks, bonds, property and financial engineering. Financial claims multiplied far faster than the growth of the underlying physical economy.
Today that relationship is changing.
A growing number of investors believe we are entering a period where scarcity of physical resources matters more than abundance of financial capital. Energy security, supply chains, demographics, rearmament, reshoring and geopolitical fragmentation are all placing renewed emphasis on tangible assets rather than paper claims.
If this thesis proves correct, capital may continue rotating from financial assets towards the physical foundations of industrial civilisation.
The key question is not whether such a rotation occurs, but in what sequence.
Financial assets – Claims on future cash flows such as shares, bonds and derivatives.
Physical assets – Tangible resources such as energy, metals, farmland and infrastructure.

2. PHASE ONE: MONETARY DEFENCE
The first destination is usually the monetary metals gold and silver.
Gold requires no economic growth, no earnings and no productive activity. Its primary function is monetary defence. When investors become concerned about inflation, excessive debt, currency debasement or geopolitical instability, gold often becomes the first refuge.
Historically, gold tends to move before most other commodity sectors because it responds directly to monetary fears.
Silver occupies a unique position. It is both a monetary metal and an industrial metal. Early in a cycle gold often leads. Later, as industrial demand strengthens, silver can outperform.
Mining companies typically lag the initial rise in bullion prices before accelerating as higher commodity prices flow through to profits.
Possible ETF examples include:
• Physical gold funds such as SGLN, GLD, IAU and SGOL
• Gold miner funds such as GDX, GDXJ, AUCP and RING
• Silver funds such as SLV and SIVR.
A common hierarchy is:
Physical gold (SGLN, IAU, GLD)
Senior miners (AUCP, GDX)
Junior miners (GDXJ)
Monetary defence – Preserving purchasing power during periods of financial instability.
Senior miner – A large established producer with multiple operating mines, significant reserves and substantial cash flow.
Junior miner – A smaller producer, developer or explorer with higher growth potential but greater operational and financial risk.

3. PHASE TWO: ENERGY BECOMES THE FOCUS
Energy is the master commodity and priority in America's strategy for global hegemony, explaining much of its foreign policy.
In 1971 US spending and inflation were soaring because of the Vietnam and public spending programs. President Nixon left the Bretton Woods system which linked the dollar to gold. But with high inflation and no gold backing, would the world still want to hold dollars? In 1974, Nixon (Kissinger) put it back - not on gold, but on oil.
The US reached a deal with Saudi Arabia to price oil exclusively in US dollars in return for US military and economic support. Other OPEC nations soon followed. From that point on demand for energy meant global demand for dollars. This was the start of America's "exorbitant privilege".
Every mine, farm, factory, truck, ship and data centre depends upon energy. Rising energy costs eventually spread through the entire economy.
This phase becomes particularly powerful when investors conclude that supply constraints are structural rather than temporary.
Recent tensions around the Strait of Hormuz are illustrating this dynamic. Markets can tolerate cyclical disruptions. They react very differently when critical transport routes appear vulnerable over extended periods.
Oil and gas producers often benefit first. Pipeline operators follow. Uranium has become increasingly important because nuclear energy requires long planning horizons and substantial capital investment.
Unlike many commodities, new uranium supply can take a decade or more to develop, creating the potential for prolonged shortages.
Possible ETF examples include:
• XLE, VDE and IXC for broad energy exposure
• URA and URNM for uranium exposure
Structural shortage – A shortage caused by long-term supply limitations rather than temporary disruptions.

4. PHASE THREE: INDUSTRIAL AND STRATEGIC METALS
Once energy pressures begin filtering through the economy, attention often shifts towards industrial metals.
Copper is frequently called the metal of civilisation.
Electric grids, renewable energy systems, electric vehicles, data centres, military equipment and industrial reshoring all require enormous quantities of copper.
Aluminium plays a similar role across transport, aerospace and manufacturing.
Rare earth elements occupy a special category. They are essential for modern electronics, advanced motors, missile guidance systems and defence technologies. Yet production remains highly concentrated geographically, creating strategic vulnerabilities.
As governments pursue both energy transition and military rearmament, demand for these materials may remain robust for years.
Possible ETF examples include:
• AIGI for industrial metals
• COPX for copper miners
• PICK for diversified mining exposure
• REMX for rare earth and strategic metals
Rare earths – A group of strategically important elements used in advanced technologies and defence systems.

5. PHASE FOUR: AGRICULTURE AND FERTILISERS
Food inflation tends to arrive later - although as much as half of the world's fertilizer is produced from compounds from the Gulf putting very large numbers of people into food scarcity possibly by autumn this year.
Governments intervene aggressively when food prices rise because food security is politically sensitive.
Nevertheless, agriculture remains heavily dependent on energy and fertilisers.
Nitrogen fertiliser depends largely on natural gas. Phosphate production is concentrated in a small number of countries. Potash supply remains influenced by geopolitical developments involving Ukraine Russia and Belarus.
These dependencies mean agricultural markets can become vulnerable after prolonged energy shocks.
Agricultural commodity funds offer one route for investors, although many rely upon futures contracts and therefore incur roll costs that may reduce long-term returns.
Agribusiness companies and fertiliser producers often provide a more durable route into the sector.
Possible ETF examples include:
• DBA for diversified agricultural commodities
• WEAT and CORN for specific crop exposure
• MOO and VEGI for agribusiness exposure
Roll cost – The cost incurred when futures contracts are repeatedly replaced as they approach expiry.

6. PHASE FIVE: INFRASTRUCTURE AND WATER
The final stage often involves long-duration real assets.
Water systems, electricity grids, ports, pipelines and transport networks are difficult to replicate and essential to economic activity.
These assets often possess pricing power and inflation linkage. They may therefore attract institutional capital seeking both income and protection against inflation.
Unlike commodity producers, infrastructure assets frequently behave more like inflation-resistant utilities.
Water deserves particular attention because population growth, industrial demand and climate pressures continue increasing its strategic importance.

Possible ETF examples include:
• PHO
• FIW
• CGW
Real asset – A physical asset whose value is linked directly to tangible economic activity.

7. WHAT ABOUT DEFENCE?
Defence occupies an unusual position.
Unlike energy, agriculture or metals, defence does not directly expand society's productive capacity. However, geopolitical competition is causing many governments to increase military expenditure substantially.
As a result, aerospace and defence companies have become beneficiaries of the current geopolitical environment.
Investors seeking exposure commonly use funds such as ITA or XAR (some non-US brokers and platforms do not offer XAR).
Whether defence spending represents productive investment or resource diversion remains a matter of debate. Economically, resources directed towards defence - like insurance - cannot simultaneously be invested elsewhere.

8. THE BIGGER PICTURE
The deeper issue is not simply inflation.
It is the possibility that the developed world is moving from an era dominated by financial abundance towards one constrained by physical scarcity.
For years capital flowed disproportionately into financial assets. Debt expanded faster than production. Asset prices rose faster than physical output.
Now the world faces ageing populations, fragmented supply chains, rearmament, energy security concerns and growing competition for strategic resources.
As these trends seem likely to persist, investors may increasingly favour ownership of the physical foundations of the economy rather than claims upon them.
Summing up
To repeat and sum up.
1. Gold as the opening chapter.
Confidence in financial claims is gradually weakening. For forty years investors have trusted: government bonds, bank deposits, property, equities, pension promises.
All are ultimately claims on future economic performance... but gold is different because it is not someone else's liability ie there is no counterparty.
We have seen how as debt rises faster than productive capacity, some investors begin preferring ownership of tangible assets rather than financial promises.
Gold's rise is being driven by four forces that appear to be acting together:
• Continuing fiat currency debasement.
• Central bank diversification away from excessive dollar dependence.
• Geopolitical fragmentation and sanctions risk.
• Growing doubts about the sustainability of debt-based financial systems.
This is the theme of this post: rotation from financial assets towards physical assets. Gold is not simply anticipating inflation, it is signalling a gradual shift in the global monetary order itself.
2. Energy as the catalyst.
Gold responds to doubts about money. Energy responds to shortages in the real economy.
Every farm, factory, mine, ship, aircraft and data centre depends on energy. When energy becomes scarce, the cost of producing and transporting almost everything rises.
This is why energy often acts as the catalyst in the rotation from financial assets to physical assets. Gold may signal the problem, but energy spreads its effects throughout the economy.
3. Industrial Metals, Agriculture, Infrastructure and Water: The Longer Story
Gold protects wealth. Energy powers the economy. But industrial metals, agriculture, infrastructure and water are the foundations upon which civilisation itself depends.
Copper, aluminium and rare earths are essential for electrification, rearmament and industrial production. Agriculture feeds populations. Infrastructure moves goods, power and information. Water sustains every economic activity.
These sectors tend to attract capital later in the cycle because shortages take longer to develop and are often masked by government intervention. Yet they may ultimately prove the most important, because they represent the physical systems that modern societies cannot function without.
4. Defence
ITA — largest and most established.
PPA — broader exposure and less concentrated.
DFNS — best UCITS choice for UK/European investors.
SHLD — focuses on newer defence technologies.
XAR — equal-weighted approach, but not available everywhere.
Glossary - gold
Financial repression - the aim is to reduce the real value of the debt ie in pp terms aka "burn off the debt". Governments achieve this with policies to keep interest rates artificially low. If interest rates can be kept low this helps government pay the interest on their debt and if kept below inflation this reduces the real value in purchasing power terms.
Financial repression is achieved with low interest rates, inflation above interest rates, regulations requiring institutions to hold government bonds - eg stablecoin must be collaterised with U.S treasuries - and limits on capital movement.
Limits on Capital movement
Governments can limit financial freedom by restricting access to foreign currencies, limiting transfers abroad, taxing overseas investments, imposing withdrawal restrictions, requiring institutions to hold government debt, or making it harder to move savings outside the domestic financial system.
The common objective is to keep capital at home and help finance government borrowing at lower cost.
Fiat currency - A currency whose value depends on government authority rather than convertibility into a physical commodity such as gold.
Monetary debasement - A reduction in the purchasing power of money through inflation or excessive creation of currency.
Reserve diversification - Holding a variety of reserve assets rather than concentrating entirely in one currency.
Real interest rate - The interest rate after inflation has been deducted.
Monetary Order - The system of rules, as maintained by institutions and agreements, that determine how money is created, stored, exchanged and trusted within an economy or between nations. Examples include the gold standard, the Bretton Woods system, and today's fiat currency system centred on central banks and money issued by banks, CBs and government treasuries.
A monetary order ultimately answers three questions: What is money? Who controls it? Why do people trust it?
Real burden of debt - The value of debt after allowing for inflation - monetary or financial repression is intended to reduce what govt debt is worth in purchasing-power terms.
Glossary - energy
Master commodity - A commodity whose price influences the cost of producing and transporting almost everything else in the economy.
Catalyst - An event or force that accelerates a larger change already developing beneath the surface.
Energy security - The ability of a nation or economy to obtain reliable and affordable supplies of energy.
Glossary - Metals, Ag, Infrastructure and Water
Industrial metals - Metals such as copper and aluminium that are essential for construction, manufacturing and energy systems.
Infrastructure - The physical networks, such as grids, pipelines, ports and transport systems, that support economic activity.
Real economy - The production and consumption of actual goods and services, as opposed to financial transactions and asset trading.
