Japan’s bond market is breaking. In late April, the Bank of Japan spent $60 billion in two weeks to prop up the yen - a pace that previously took two months. Each intervention barely moves the dollar-yen rate before it snaps back. As Marty Bent reported on Rabbit Hole Recap, the 20-year JGB yield hit its highest since 1997. The market is signaling what Peruvian Bull called on TFTC: Japan is the canary in the coal mine for global sovereign debt.
Prime Minister Sanai Takeichi’s reversal - embracing deficit spending while cutting the consumption tax - has investors fleeing. Japan’s debt-to-GDP ratio stands at 260%, and its life insurers and pension funds sit on roughly $8 trillion in unrealized losses on long-dated JGBs. With 90% of energy imported in dollars, every yen dip inflates import costs, forcing more dollar purchases and further weakening the currency. It’s a doom loop.
"The Bank of Japan is throwing pebbles at a raging fire. They can’t hike rates - their entire financial system would implode."

The U.S. isn’t immune. Matt Odell noted on Rabbit Hole Recap that U.S. interest expense crossed $1.27 trillion over the past year - now larger than Social Security outlays. The 30-year Treasury yield settled above 5% in a recent auction, the highest since 2007. Foreign buyers once funded 70% of new issuance; now it’s just 14%. The marginal buyer is domestic - banks, money market funds, and the Fed by stealth.
Peruvian Bull argues stablecoins won’t save the system. Even $4 trillion in projected demand is a rounding error against a $40 trillion Treasury market headed to $70 trillion. The real fix? Regulatory backdoors: forcing money market funds into short-term bills, adjusting SLR rules, or pushing CBDCs to monetize debt without balance sheet expansion. It’s not QE - it’s coercion.
Japan’s crisis isn’t isolated. It’s the first domino. When the world’s largest creditor starts unraveling, everything from U.S. equities to Bitcoin feels the tremor. The only escape - massive fiscal austerity - is politically impossible. So the central banks keep spending, the bond vigilantes keep selling, and the forest fire spreads.
"If Japan breaks, the fallout hits everything: U.S. equities, Bitcoin, the global financial plumbing. They’re not just burning reserves - they’re burning credibility."
