Prisoners of the Yen

On December 29, 1989, the Nikkei 225 closed at 38,915 - the highest it had ever been, or would be again for thirty-four years. The land beneath the Imperial Palace was said to be worth as much as all the land in California.

The conventional account calls this a fever: a mania that gripped a people and then broke. That telling is incomplete rather than wrong, and its incompleteness matters, because it treats the bubble as something that happened to Japan rather than something that was done. Prisoners of the Yen begins from the opposite premise. Japan's bubble was manufactured - the visible output of a credit machine whose throttle was held by a small circle of officials at the Bank of Japan. Richard Werner called them the Princes of the Yen.

This book follows that machine across four decades: the balance-sheet recession that followed the crash, the lost decades, Abenomics and the monetization of the escape, and the deferred bill that came due in the 2020s. It arrives at the trilemma facing Tokyo now. A government cannot hold cheap debt service, a defended yen, and normalized interest rates at the same time. One horn must be sacrificed.

The book names three roads and assigns each a probability. Case A, consolidation, in which savers and spending absorb the cost - the outcome a crisis produces rather than a government chooses. Case B, reflation and debasement, in which the currency absorbs the strain the bond market and the budget refuse to bear - the path of least resistance, and this book's base case. Case C, fiscal dominance, in which the central bank is re-subordinated to the Treasury - the accident attractor, reached not by choice but by a bond market that will not clear.

And it argues the question is no longer Japan's alone. Through the carry trade that funds the world's risk-taking, through the Treasury holdings Tokyo must sell to defend its currency, and through the emergency plumbing that in 2026 bound the Federal Reserve into the yen's defense, the United States has made itself a prisoner of the yen as well.

Japan is the canary. The developed world is the coal mine. What happens in Tokyo is a preview rather than an exception.
