Within the asset class allocation framework, the only commodities that matter are copper and crude oil; all others are excluded due to locality or insufficient scale. Copper and crude oil represent two distinct mechanisms — observing the boundary of real aggregate demand versus supply-side shocks. Commodity prices are determined by the superposition of three layers — real demand, investment demand, and speculative demand — and when financial regulation tightens all three layers retreat and the commodity supercycle ends. After de-financialization, the prerequisite judgments for any commodity market assessment converge to three questions.
The Framework As It Stands
This section is compiled from research drafts: the original framework’s structure, terminology, and key formulations are preserved, including editorial bridging and external factual annotations; charts were drawn by the compiler according to the original framework’s structure.
I. Three Threads
Sections 3.1–3.3 characterize the commodity framework: within the asset class universe, commodities are not “all equally important” — rather, copper and crude oil are the two core commodities that enter the macro asset framework through financialization, carry trading, inventory/warehousing/financing, regulatory cycles, and supply-side shocks.
- Thread A — Commodities are not protagonists but instruments/vehicles. The core commodities within the global asset class are copper and crude; commodities serve more as vehicles for global carry trading rather than isolated supply-demand targets. The commodities that genuinely enter asset class allocation are copper and crude — not locally-traded products like iron ore or rebar.
- Thread B — Commodity prices are jointly determined by real demand and financial demand. This is continuous with the era of financialization expansion described in The End of the Great Moderation: The Collapse of Globalization’s Two Pillars: the post-2002 commodity superbull was not purely rigid demand — regulatory loosening and leverage loosening brought in financial demand, producing a superposition of real demand, investment demand, and speculative demand; once regulation tightened, capital withdrew, volatility declined, and the commodity supercycle ended.
- Thread C — The frameworks for copper and crude are entirely different. Copper has a short supply chain; real aggregate demand stalls and the price tops out, though financialization allowed copper to unexpectedly break to new highs in 2011. Crude is an oligopoly; demand is too diffuse and the supply side is more important — unexpected oil price moves directly affect the interest rate market and the debt-leverage equilibrium.
II. Seven Theses
-
The only core commodities in the global asset class are copper and crude oil. Copper and crude are the most important commodities from an asset allocation perspective; iron ore, rebar, etc. are not starting points. In the offshore asset framework, commodities function as vehicles for global carry trading within the rates/FX framework — “doing commodity supply-demand research” must not be conflated with “using commodities to carry out carry financing.”
-
The post-2002 commodity superbull contained financial demand; it was not purely real demand. Crude rose from around 140 before the financial crisis, yet global energy total demand growth ended in 2006; 2006–2008 was driven more by financial behavior causing asset price overheating. Traditional commodity analysts who erred in 2009–2012 did so because they conflated demand concepts and anchored to historical prices from a prior institutional regime.
-
China carry trading caused certain commodities to “add five or six” beyond expectations. After the Four-Trillion stimulus, the expected net of external minus-two plus China plus-three should have been plus-one, but commodities like copper reacted excessively due to the additional financial demand from carry trading. Post-2009, with U.S. benchmark rates at 0.25%, China’s counter-cyclical management boosted aggregate demand and added financial leverage, forming a structure of borrowing dollars offshore and buying RMB assets onshore. Copper, aluminium, lead-zinc, soybeans, and palm oil — commodities that could be quickly liquidated and easily stored — became financing vehicles.
-
Financial capital’s entry reshapes commodity supply-demand, inventory, and seasonality. Once Wall Street FICC desks entered commodity supply chains — from exploration, extraction, investment, production, processing, smelting, sales, warehousing, and logistics through to trading — every link could be rebuilt around financial business. Shadow inventory, pledged financing, the contango storage game, and switching between visible and hidden inventory rendered traditional inventory/supply-demand frameworks invalid. When financial regulation tightened, capital withdrew and the commodity supercycle ended.
-
Copper is the commodity to watch for short-cycle real aggregate demand and the boundary of financialization. Copper’s supply chain and cycle are relatively short; if real aggregate demand cannot push prices higher, the market tops. In 2005–2008 copper did not make new highs, signaling the commodity cycle had ended — but levered assets like crude and A-shares could still rise; a copper peak does not equal an asset-price peak. In 2011 copper surged unexpectedly due to carry trading and a copper spot ETF application; a spot ETF could monetize the commodity and lock up supply, re-enacting the Hunt Brothers’ silver-manipulation logic of violent rise and collapse.
-
Crude is the king of commodities because the supply side and rate/debt transmission are more critical. Crude is an oligopoly; the supply curve has a greater effect on prices than the demand curve; downstream demand is too granular to cover precisely. The strategic principle is therefore to treat demand as the baseline and capture supply-side changes only. Unexpected crude moves affect the interest rate market and thereby the debt-leverage equilibrium; every sharp rise or fall in oil prices carries macro consequences.
-
After de-financialization, commodities revert to traditional supply-demand and a low-volatility range. 2002–2012 was the most profitable decade for China’s commodity traders, as the three-layer demand superposition drove the rise of commodity traders; post-2014–15, the thesis was that after deleveraging is complete commodities revert to traditional supply-demand, with no room for unexpected large aggregate demand expansion globally, and supply contractions only producing range-bound volatility. Future commodity market conditions depend on three questions: Is there a region that can replace China’s growth and leverage addition? Does Europe or the U.S. have room to re-lever? Is financial regulation in Europe or the U.S. loosened again? If all three answers are no, most commodities remain low-volatility and range-bound, and capital disturbances in small commodities do not constitute a cycle-restart signal and do not enter the asset class framework.

Interface Layer
The framework’s most critical contribution is splitting “commodity analysis” into two layers — the supply-demand layer and the financialization layer — which must not be conflated, and for which specific historical cases are available for verification.
The specific error made by traditional commodity analysts in 2009–2012 was: using demand fundamental anchors from before 2002 to make price forecasts, and extrapolating the anomalous stimulus of “external minus-two plus China plus-three equaling actual plus-five or plus-six” that appeared after the Four-Trillion stimulus as real aggregate demand growth — the result was systematically mis-pricing a market where financial demand was already dominant by applying, as a supposed cure, historical prices from before the institutional change. The framework’s correction: first judge the proportion of financial demand within the price driver; if the regulatory and leverage cycle is reversing, all three demand layers retreat simultaneously and traditional supply-demand floor valuations cannot provide support.
The asymmetry between copper and crude is especially important here: copper’s financialization boundary can be assessed by “peaks when real aggregate demand stalls,” and in 2005–2008 copper did not make new highs while crude was still rising — meaning the two can diverge within the same commodity cycle. Equating copper’s peak with crude’s peak is a specific error easily made when reading the framework.
The three post-de-financialization questions (China substitute growth / European-American new leverage space / European-American financial re-regulation) form this entry’s proprietary pre-conditions checklist for market conditions. If all three answers are simultaneously negative, the asset class commodity framework projects range-bound volatility; violent moves caused by capital intrusion into small commodities do not constitute a cycle-restart signal — the two must be distinguished.
Data timestamp: The theses above derive from a June 2019 course. Crude at approximately 140 before the financial crisis, and copper’s failure to make new highs in 2005–2008, are all as of the 2019 data vintage; when applying this framework, connect to current real-time curves and regulatory environment.
