The Financial Attributes of Oil: The Fisher Triad Extension and from Petrodollar to Dollar-Oil

An analytical framework for the financial attributes of oil, grounded in a triad extension of Fisher’s quantity theory of money MV=PQ (money–commodity–asset), arguing for the meta-proposition that “all price phenomena are ultimately monetary phenomena.” The framework maps the two-way closed loop by which the three monetary-price variables (interest rate / exchange rate / dollar index) positively transmit to oil prices, while oil prices as a leading inflation indicator feed back in reverse to monetary interest rates — and traces the structural reconstruction of the dollar–oil relationship from the traditional negative correlation to positive or neutral following the shale revolution.

Core Mainline and Three Sub-Themes

This framework establishes “how to understand oil prices from a monetary-financial perspective” — placing oil prices inside Fisher’s quantity theory of money MV=PQ triad extension framework (money–commodity–asset) and arguing four main lines: (1) The root of price phenomena is monetary phenomena — the Fisher formula splits the commodity side into “commodities” and “assets,” constructing a money–commodity–asset triad and yielding “all price phenomena are, at bottom, monetary phenomena”; (2) Money itself has three price variables — the interest rate (the price of money), the exchange rate (cross-region price comparison), and the dollar index (a weighted basket exchange rate) — which positively transmit to oil prices; (3) Oil prices as a “leading inflation indicator” feed back in reverse to monetary interest rates, forming a two-way closed loop; (4) After the shale revolution, the U.S. shifted from “petrodollar” to “dollar-oil,” moving the dollar–oil relationship from the traditional negative correlation toward positive or neutral.

Sub-theme A — Fisher Formula Triad Extension + the Meta-Proposition “Price Phenomena = Monetary Phenomena”

The Fisher formula MV=PQ (money supply × velocity = commodity price × quantity) splits the commodity side into “commodities” and “assets,” constructing a money–commodity–asset triad (analogous to money as a kettle, commodities and assets as cups). The triad is more complex than the dyad: a dyad has 4 combinations (2×2); the triad has 8 (2×2×2). This creates “counter-intuitive phenomena” — money supply increases (left side of the equation grows) but commodity and asset prices fall (right side does not grow), meaning effective money supply has not flowed to the commodity and asset side, producing a disconnect. Meta-proposition: all price phenomena are, at bottom, monetary phenomena.

Sub-theme B — Three Monetary Price Variables Positively Transmit to Oil × Oil → Monetary Feedback = Two-Way Closed Loop

The price of money = interest (interest rate); a country’s currency strength is closely related to its interest rate, but seigniorage rights determine the essence — the dollar is active; currencies of developing countries are not internationalized and must obtain currency through commodity exchange (passive); the issuance mechanisms are fundamentally different. Counter-example clarification: high interest rates in hyperinflationary countries do not represent a strong currency. The price of the dollar = the dollar interest rate; interest rates at different maturities (fed funds rate / 1/5/10/20-year Treasuries) can form a forward curve (term structure of rates).

The exchange rate = cross-region price spread / cross-region price comparison. The interest rate is a price (absolute strength), the exchange rate is a price difference (relative strength); the two are correlated but offset and operate through different mechanisms. The dollar index = a weighted basket exchange rate, mainly comprising developed-country currencies such as the euro, yen, pound sterling, and Swiss franc.

Transmission chain: dollar index rises → dollar strengthens → all non-dollar currencies convert to fewer dollars → equivalent to a contraction of global money stock → deflationary effect → transmitted through the Fisher formula, with prices falling when total commodity quantities are unchanged. Traditional rule: dollar index and oil price are negatively correlated. Why the rule breaks down: the G8 (eight advanced countries) used to account for 70%–80% of global share, now only 40%–50%; expanding to G20 brings at least seven-tenths of global GDP, but the dollar index covers only the G8 system and does not reflect the G20 system. The loss of the rule is not a mechanical error — the objective situation has changed.

⚠️ Monetary market Contango/Backwardation (the framework explicitly labels this: personal view · unproven): Monetary market Contango (near-end rate low, far-end rate high) = excess demand (opposite of the commodity market); Backwardation (near-end rate high, far-end rate low) = severely excess supply. When the rate market is near-high/far-low, it means the dollar money market is severely over-supplied and money cannot flow into the commodity and asset side.

Reverse channel (oil prices → money): Oil prices = leading inflation indicator; oil = king of commodities. Scale of energy consumption: all grain and food combined = 1/10 of total energy consumption (converted to barrel-of-oil equivalent); energy is the largest commodity, and oil accounts for 1/3 of energy consumption. Transmission mechanism: crude oil price rises → energy costs increase → gasoline and diesel prices are first to rise → transmit to other industries → cost of living rises → income and demand increase → overall commodity prices rise → generating inflationary pressure. The inflation indicator central banks monitor used to be CPI; now they focus more on core inflation PPC (as of the 2019 time point); ten-year Treasury Inflation-Protected Securities (TIPS) track positively with oil prices; sustained oil price increases feed back in reverse to dollar interest rates.

Sub-theme C — Shift from Petrodollar to Dollar-Oil System, Reconstruction of the Dollar–Oil Relationship

After the collapse of the Bretton Woods system, the world moved from gold peg to fiat currency. Traditional circulation: developed countries (Europe and the U.S.) print money → buy commodities and oil; developing countries accumulate current-account surpluses from general trade, oil-producing countries accumulate oil surpluses; all surpluses recycle back to the U.S. Treasury market — bought back from the capital side. The current contradiction is the debt problem and the role contradiction.

The petrodollar system was established when the U.S. lacked oil and worried about future sustained supply; a petrodollar sub-system was constructed within the monetary architecture. The major shift: previously the U.S. was highly dependent on imports; now it has become an energy exporter and a producing country (paraphrased as “every green bill, if squeezed, drips a drop of oil”); the transition is from “petrodollar” to “dollar-oil.” Recent implication (as of 2019): rising oil prices are likely to support the dollar, changing the relationship from the traditional inverse to positive or neutral — which also explains “the dollar index–oil price negative-correlation rule losing effect” (the structural shift from G8 to G20).

Compiler’s Perspective

Coordinates: Category · Energy and Commodities / Axis · Fa / Perspective · Why It Is So

The common path for analyzing oil prices is to mechanically apply the “stronger dollar → weaker oil” negative-correlation rule — this was a valid approximation in the G8 era (G8 accounting for 70%–80% of global GDP), but the G8 share has fallen to 40%–50%, while the G20 accounts for at least seven-tenths of global GDP yet carries no weight in the dollar index. Mechanical application under the G20 configuration leads to systematic misjudgment: even if the dollar index strengthens, if currency zones outside the dollar index simultaneously expand, global money stock does not contract and oil prices need not fall. This framework provides a more upstream diagnostic sequence: first read the direction of money’s three price variables (interest rate / exchange rate / dollar index), then judge whether the dollar index still represents the global monetary configuration, and finally correct the direction of the dollar–oil relationship according to the petrodollar→dollar-oil system shift.

Proprietary addition: The Fisher triad framework’s “counter-intuitive phenomenon” (money supply increases but commodity/asset prices fall) is a diagnostic item unique to this framework. Conventional analysis links monetary easing directly to rising oil prices, but if money does not flow into the commodity and asset side, expansion can coexist with falling commodities; identifying this disconnect gives “QE easing but commodities falling” a structural explanation rather than mere after-the-fact narrative.

Seeing Is Not Believing: What You Believe Is More Useful Than What Is Real: The “dollar index–oil price negative-correlation rule losing effect” due to the G8→G20 structural shift is information that has already materialized, yet most analysts continue applying the old rule — this is exactly the cognitive gap that anchor points to: the failure boundary of a rule must be actively constructed, not inferred by extrapolating historical correlations.

The monetary market Contango/Backwardation section is explicitly labeled by this framework as “personal view · unproven”; when citing it, this boundary must be retained and it must not be presented as an established mechanism.
