a fragile equlibrium
market vibes
The Yen carry first became a prominent strategy in the late 1990s and accelerated in scale during the post GFC negative interest rate era. Investors borrowed in Yen at zero to fund higher-yielding assets primarily US Treasuries and equities.
There is no single, universally agreed-upon figure for the current dollar value of outstanding Yen carry exposure. It’s a mix of speculative leveraged positions, bank lending, corporate borrowing, and foreign investments by Japanese institutions. Estimates vary widely depending on the definition. These are the three largest categories tracked by central banks, the BIS, and money center banks:
*Speculative positions via FX swaps on margin: Analysts describe it as “substantial” but public figures are scarce; mostly anecdotal comments, positioning data, CFTC COTs etc suggest it’s likely $500 billion to $1 trillion or more in aggregate exposure.
*Foreign assets with “carry-like” exposure (including Japanese insurers, pension funds, banks, and corporates holding USD assets, Treasuries, equities, etc.): Japan’s net international investment position exceeds $3–4 trillion with gross foreign assets around $4–5 trillion (BIS, Japan MOF IIP). A large part acts like carry exposure because interest rate differentials are shrinking and Yen is weak. Some headline estimates of carry-like exposure are as high as $20 trillion (BIS and Deutsche Bank), but these are implied and based on various sources of official and public trade data.
Speculative exposure is somewhere in the $500 billion to low trillions range. Japanese foreign capital deployment is in the 5 trillion+ bucket. These trillions of swap risk are a systemic issue not unlike TBTF banks post GFC. It grew. The same fragile equlibrium was tested in the summer of 2024.
