Physical Commodity Markets: Oil, Gas, Copper, Critical Minerals, and Structural Signals

Commodities are not just price charts on a Bloomberg terminal. Each is a physical market with its own geological constraints, logistical bottlenecks, geopolitical power dynamics, and proprietary signals. European natural gas delivered a warning signal of energy vulnerability in 2022 that equity markets only priced in months later. Copper signals a structural tension between the acceleration of the energy transition and the inertia of mining capacity. Oil sits at the intersection of the business cycle, OPEC+ discipline, and structural underinvestment in exploration. Critical minerals are redrawing the map of global geopolitical dependence.

The question structuring this sub-pillar is not “should one invest in commodities?” (it is: what do physical markets) oil, gas, copper, critical metals, reveal about the structural constraints weighing on the real economy, and what forward signals do they provide? These market-by-market price signals are gathered in our commodity prices hub.

Oil: between OPEC+ discipline and structural underinvestment

The global oil market remains the largest commodity market and the one most directly linked to the macroeconomic cycle. Three forces define the current regime. A complementary angle: uranium’s macro behaviour.

Refining margins: the intermediate signal

The price of crude tells only part of the story. Refining margins, the spread between crude prices and refined products (gasoline, diesel, jet fuel), often provide a more revealing signal of real energy-market conditions. The European diesel crack spread exceeded $60 per barrel in 2022 (Platts), and it returned above $60 in 2026: the 2022 spike reads less as an anomaly than as a template. What the spread priced was a refining bottleneck rather than crude scarcity: global refining capacity fell in 2021 for the first time in decades (IEA), with substantial capacity shut or converted since 2020, only partly offset by new plants in Asia and the Middle East. Crude carries the cyclical signal, which is the frame of our study on WTI: Reading Crude Oil Price as a Macro Signal of Economic Cycles; the crack spread carries the transformation signal, reconstructed over the long run in Refining margins: the true barometer of oil profits; and the price of energy relative to monetary assets adds a third layer, documented in the gold-to-oil ratio as an energy-money regime signal. At the household end of that chain, fuel as a share of income can be quantified with the fuel burden calculator.

Natural gas: the Europe–world energy fracture

The natural gas market experienced the most violent dislocation in its history in 2022, and the structural consequences remain far from resolved. European TTF natural gas reached €340/MWh in August 2022 (ICE), many times its 2015–2020 average. US Henry Hub, tied to a self-sufficient domestic market, remained below $10/MMBtu (NYMEX). This benchmark divergence is the subject of why natural gas has no single world price. This price gap represented the largest competitiveness shock faced by European industry since the 1970s. Source data: the jet fuel spot price dataset.

The restructuring of Europe’s gas market after the Russian supply break (Russian imports fell from 155 bcm/year in 2021 to under 15 bcm in 2024, Eurostat/Bruegel) was absorbed through three mechanisms: a massive rise in LNG imports (mainly US and Qatar, IEA), industrial demand destruction (European industrial gas consumption -15% to -20% in 2022–2023, Eurostat), and accelerated renewables deployment. The cumulative cost to Europe exceeded €200 billion in additional energy expenses in 2022 (Bruegel). German industrial competitiveness was structurally affected: industrial output has not returned to pre-2022 levels (Destatis). Field analysis is developed in Natural gas market: the signal nobody is watching. Related material: our study on the uranium cycle now driven by compute demand.

Copper: the metal of transition and macro diagnosis

Copper holds a unique position among commodities: it is both a leading cyclical indicator (“Dr. Copper”) and a marker of structural transformation (electrification, energy transition, data centers). Annual demand of 26 million tons (ICSG, 2024) is distributed across construction (25%), electronics (25%), transport (12%), and energy (15%): diversification that makes copper a barometer of global economic activity. WTI crude as a macro cycle signal extends this reading.

The structural signal is a growing deficit. The IEA estimates copper demand linked to clean technologies will rise steeply by 2040 (Critical Minerals Market Review). Such a rise in demand for one metal presumes a build-out whose economics now turn on the falling cost of battery storage. Meanwhile, global LME copper inventories fell to critical levels at end-2023, equivalent to only a few hours of global consumption (LME). The pipeline of new mining projects is insufficient: long development timelines (10–15 years, S&P Global MI), regulatory constraints, and rising capex limit supply response. Copper hit an all-time high in May 2024 (LME). Field analysis is developed in Copper prices: a quiet signal of global reindustrialization.

Critical minerals: the new map of dependency

The energy transition has created a new geography of resource dependence. Lithium, cobalt, nickel, rare earths, graphite, and gallium have become the strategic commodities of the 21st century, and their geographic concentration is unprecedented. A related perspective: our study of the gold-silver ratio as a mean-reversion signal.

China accounts for nearly 70% of rare earth mine production and about 80% of natural graphite production, as well as most cobalt refining (USGS/IEA). The Democratic Republic of Congo extracts nearly three quarters of global cobalt (USGS, 2025). Because those concentrations sit upstream of every battery line and every turbine, permitting and mine development weigh as heavily as order books on the capital the energy transition actually requires. Australia and Chile produce about half of the world’s mined lithium (USGS, 2025). Lithium prices illustrate the violence of cycles in these narrow markets: prices surged to a peak near $80,000/ton by end-2022 before falling sharply by end-2024 (Benchmark Mineral Intelligence), a violent swing in four years, reflecting the collision between exploding demand (EV sales rising steeply, IEA) and mining investment cycles that cannot keep pace, within a broader context of geopolitical fragmentation reshaping global market structures. More context: our study on the 2022 LME nickel squeeze as structural fragility.

The use of these minerals as geopolitical leverage is already underway. China restricted exports of gallium and germanium (Aug 2023), graphite (Dec 2023), and antimony (Aug 2024, MOFCOM). Export controls used this way turn a mining statistic into a policy instrument, which is the whole subject of the geopolitics of critical mineral supply chains. Consumer countries responded with diversification strategies, the US Critical Minerals Act and the EU Critical Raw Materials Act, but timelines to build alternative capacity are measured in decades.

Palladium: a narrow market under structural pressure

The palladium market illustrates dynamics specific to narrow and highly concentrated commodity markets. The macro context is developed in our study on why European gas has no global price and what it cost. Global palladium production is dominated by Russia and South Africa. Demand depends 80% on the automotive sector (catalytic converters, Johnson Matthey). Palladium reached a record $3,440/oz in March 2022 (NYMEX), driven by Russian sanctions and semiconductor shortages limiting car production (and thus catalyst recycling), before falling below $1,000 in 2024 as electric vehicle adoption rose (which does not use catalytic converters). The reversal was structural: from chronic shortage to anticipated surplus in two years. A broader view: the access routes to commodities and their costs.

The dominance of Russia and South Africa has tonnages behind it. The USGS Mineral Commodity Summaries 2026 estimates 2025 world mine production at about 190 tonnes, of which 84 came from Russia and 70 from South Africa, close to 44% and 37% of the total. Canada (16 tonnes), Zimbabwe (15) and the United States (6.2) trail far behind, and South African output is falling, from 82.6 tonnes in 2024, as mines close or rationalise. The same source puts the annual average price at $2,419 an ounce in 2021 and $995 in 2024, a 59% drop in three years.

Russian concentration also became a US trade case. Following a petition by Stillwater and the United Steelworkers, the Commerce Department set a dumping margin of 132.83% and a countervailing duty rate of 109.10% on unwrought Russian palladium in 2026 (Federal Register, May 1, 2026, and May 22). On June 15, 2026, the International Trade Commission reached a negative final determination, finding no material injury to the US industry.

Battery-electric cars carry no catalyst, but plug-in hybrids keep a combustion engine and therefore one, so statistics that add the two together overstate the metal removed. Regulation pulls the other way. Europe’s Euro 7 standard, applied to new models from 2026, tightens real-driving tests and extends durability requirements for emissions systems, and Johnson Matthey expects an initial rise in metal loadings per vehicle. Recycling is the least discussed variable: catalysts from scrapped cars give their metal back, a pool that grows as the gasoline fleet sold in the 2010s ages. Johnson Matthey forecasts a further rise in autocatalyst recycling in 2026, and with it a move from a deficit in 2025 to a surplus in 2026.
