The Ledger · Medium — two to fifteen years

GP-12 The debt is repaid by repression, not default

Status: OPEN

From The Rational Prophet (Book Four of The Laws of Game Theory)

The bet

The bet: The debt cycle resolves through negative real returns to savers rather than through default or a growth miracle.
Win: Real yields negative in the majority of years of the band, in at least three G7 states at once.
Lose: Sustained positive real yields alongside a falling debt ratio, or a large-scale formal restructuring.
Expiry: Five to fifteen years.
Check it: Ten-year sovereign yields from FRED and the OECD; the headline consumer price index of each national statistics office.

In protocol form

Word for word from Appendix D of the book, the Prediction Protocol, where this bet is entered as Repression. References to sections (§) are to that appendix.

Universe: the G7 states: Canada, France, Germany, Italy, Japan, the United Kingdom and the United States.
Source: ten-year sovereign yields, from FRED and the OECD; the headline consumer price index, from each state's national statistics office.
Definitions: real yield is the nominal ten-year sovereign yield minus the officially reported annual consumer price inflation rate — expressly not an alternative or adjusted measure. The officially reported rate is the headline consumer price index published by the national statistics office; for the United Kingdom that is the CPI, not the CPIH.
Calculation: annual average per state; count years in which at least three G7 states are at once negative; the bet wins if those years are a majority of the years in the band.
Baseline: real yield per state, in the latest month for which both inputs are published for all seven.
