Carry Trade Unwind

Carry trade unwind is the episode’s mechanism for how a currency and rate shock can force investors to sell unrelated-looking assets. In EP38 风满楼！全球资本市场巨幅动荡，腥风血雨时刻近在咫尺, the focus is a yen-funded unwind: as the yen strengthens and Japanese rates rise, positions funded by cheap yen become less profitable or loss-making, so traders close positions and sell risk assets.

Key Claims

• An unwind is not only a forecast change; it can be a mechanical reaction to margin, funding cost, stop-losses, and currency losses.
• Asset sales can become correlated because the same funding trade sits underneath many positions.
• Forced buying of yen to repay funding can push the yen higher, creating a feedback loop.
• If index futures, options, or leveraged funds are involved, the unwind can become Derivative Amplified Volatility rather than a smooth repricing.

Connections

• Yen Carry Trade — specific trade structure behind this source’s unwind discussion.
• Bank of Japan — policy trigger that changed yen funding assumptions.
• Federal Reserve — U.S. rate expectations changed the relative attractiveness of the carry.
• Market Regime Shift and Investment Risk Management — existing risk frames extended by forced deleveraging.
