Policy Regimes Are Balance-Sheet States, Not Discretionary Switches

“Using a Markov-switching reaction function and logit bridge, we show that the probability of an ‘active’ Fed regime rises systematically with total-debt-to-GDP (Ω). Policy regime is not independent; it’s a balance-sheet state.”Image
Logic (what we tested) Image
Main specification (Logit on Active indicator) Image
The Markov model’s “regime switches” are not free policy choices; they are balance-sheet phases. Rising Ω (claim load) statistically raises the probability we observe the active reaction-function state. Image
Scope: This establishes state-contingency, not a one-variable monocause. DSR and profitability also matter, consistent with a cash-flow feasibility view of policy. Image

Across specifications, the probability increases systematically with Ω, implying that policy stance is endogenously determined by debt saturation rather than exogenously chosen. Image

Why the GDP–FX Triangle Shows U.S. Output Is Energy-Constrained: A New Keynesian Restatement

"Energy throughput (Ω = E·η) is the real state variable NK models have been estimating implicitly as “productivity.”
The GDP–FX triangle reveals its existence and shows that even the United States cannot be modeled outside that global energy constraint."
Empirically, “productivity” AtA_tAt​ is correlated one-for-one with energy throughput and efficiency. Image
Inflation is now a balance between nominal demand and energy-bounded real supply — not between demand and an abstract productivity trend. Image

Energy as the Global Unit of Account and the Real Denominator

— what we can actually produce — is limited by the quantity and efficiency of energy throughput.
You cannot “print” more real output without mobilizing more usable energy or improving efficiency Image
The two triangles — one nominal (FX) and one real (GDP) — close with less than 0.05% error, which means the world’s nominal exchange structure and real output structure are internally consistent.
This implies that currencies represent proportional claims on global output, not arbitrary relative prices.Image

GDP–FX Triangle: Closure Test with Cointegration Evidence

“GDP–FX cointegrates with exchange rates at rank=1, has stable error-correction terms, and remains robust under break/out-of-sample tests. The triangle closure demonstrates system consistency. UIP fails everywhere, GDP–FX fits everywhere.”Image
👉 All three legs reject UIP simultaneously. UIP not only fails, it inverts. Image
Adjustment coefficients significant (p < 0.05), showing that FX adjusts back to equity-share fundamentals after deviations. Image

The GDP-FX Parity Triangle: Evidence That Exchange Rates Track Relative Output Capacity

........"exchange rates track relative output capacity. Far from being “free-floating” expectations around interest-rate differentials, currencies behave as shares of global production" Image
....currencies reflect shares of global output capacity. Image

Why CPI Is the Wrong Inflation Object

Accounting: CPI mixes domestic and foreign prices

Therefore, “The CPI is not the ‘true inflation’ concept relevant for domestic nominal constraints … these results demand that NK inflation theory move beyond a closed-economy CPI focus.” Image
Interpretation: CPI inflation is a weighted average of domestic inflation πD\pi^DπD and import price inflation πM\pi^MπM. Any shift in global commodity or import prices mechanically shows up in CPI, regardless of the state of domestic slack. Image
Thus the deflator tracks domestic production prices, not imported goods. Image

Why the Two Anchors Together Are More Powerful

"Because serviceability of debt and valuation of equity must both remain internally consistent with the size of the balance sheet, the economy is double-anchored. This twin constraint locks the long rate to the leverage path. Put plainly: rrr must follow ΩΩΩ."Image
Two independent necessities.

DSR comes from cash-flow accounting (flows must be payable).

DCF comes from market pricing (equity per dollar of debt must be priced consistently).
They arise from different mechanisms; agreement between them cross-validates the conclusion. Image
