The GDP-FX Triangle as Evidence that Financial Assets Function as Effective Money
"This implies that currencies are equity-linked claims, and therefore that financial assets function as money at the macroeconomic level."
Theoretical Framing
This proportionality arises because equity and debt jointly define the monetary value of domestic claims:
Empirical Results
Interpretation: The Balance-Sheet Mechanism of Currency Value
Hence, both internal and external money values are determined by asset stocks, not by base money.
Policy and Theoretical Implications
The GDP-FX triangle provides external, cross-country confirmation that financial assets function as effective money.
Domestically, credit expansion (ΔDebt) generates nominal GDP; externally, asset valuation (ΔEquity) determines the exchange value of that nominal income.
Hence, both the quantity and price of money are balance-sheet outcomes.
