Yen Appreciation Panic Impacts Global Markets, Concerns Over New Plaza Accord Resurface
Analysis indicates that the panic over yen appreciation is impacting global markets. In a joint action by the U.S. and Japan, the U.S. Treasury is buying yen, showing that long-term interest rates are increasingly driven by capital flows.
If Japan needs to defend the yen, it may pledge or sell more U.S. Treasury bonds. As the largest overseas holder of U.S. debt, its sell-off will reprice long-end yields; the yen carry trade is coming to an end with the conclusion of quantitative easing, compounded by technology companies shifting towards credit demand, further pushing up long-end rates.
On the market side, the pressure from unwinding carry trades and selling U.S. Treasuries is rising; capital is flowing from high-leverage cross-border trades to safe havens and deleveraging, putting pressure on risk assets and long-end bonds, benefiting the yen and related assets.

The recent coordinated intervention by the U.S. and Japan echoes the logic of joint actions following the Plaza Accord of 1985; Japan has long been at the core of carry trades, exporting savings to suppress global yields, and the current policy shift ends this cycle.
In terms of capital flows, investors' model of borrowing low-interest yen to allocate to U.S. stocks and bonds is being forced to reverse, motivated by the need to respond to yen appreciation and rising interest rates; this is specifically manifested in unwinding and replenishing yen margins, with funds shifting from cross-border leverage to risk reduction.
Similar cases can be seen in the volatility of carry trades in the 2010s or adjustments by past overseas holders of U.S. debt; currently, global liquidity is transitioning from a central bank-led cheap leverage phase to a capital market pricing and deleveraging phase.
This essentially represents a reconstruction of capital pathways: when the core currency of carry trades shifts, market mechanisms reprice global yields through capital flows, concentrating pricing power in entities that can respond to cross-border unwinding.
