The Bessent Hypothesis: A Structural Shift
The hypothesis suggests we are entering a "Great Rebalancing." For decades, Japan acted as the world's creditor, exporting excess savings to the US. Now, faced with domestic inflation and a need to defend the Yen, Japan is repatriating capital.
Simultaneously, the US is forced to ease to manage its debt burden. This dual-action (Japan Hiking + US Cutting) creates a pincer movement on global liquidity that markets have not priced in.
Why Japan Hikes Now
- •Core Inflation: Stickily above 2% target.
- •Wage Growth: "Shunto" negotiations yielded highest hikes in 30 years.
- •Import Costs: Weak Yen is crushing energy-dependent households.
Why US Eases Now
- •Lag Effects: 2023 hikes are now hitting the labor market.
- •Debt Service: Interest on debt exceeds defense spending.
- •CRE Crisis: Regional banks need steeper yield curves to survive.
The Anatomy of the Unwind (The "Doom Loop")
Step 1: Spread Compresses
BoJ hikes rates while Fed cuts, shrinking the profit margin for holding US assets.
Step 2: Yen Strengthens
As the spread narrows, traders buy Yen, pushing USD/JPY down from 150 to 135.
Step 3: Margin Calls
Investors who borrowed Yen to buy US Tech are now 'underwater' on the currency.
Step 4: Forced Selling
To cover margin, they must sell the US asset (Tech Stocks/Treasuries) to buy back Yen.
Step 5: Feedback Loop
Selling US assets lowers prices; buying Yen raises Yen value. The cycle accelerates.

The Grey Rhino
A "Grey Rhino" is a highly probable, high impact yet neglected threat. Unlike a "Black Swan" (unpredictable), this is charging right at us.
