2024 Yen Carry Trade Unwind

The 2024 yen carry trade unwind was the first major dislocation from BOJ policy normalization. For decades, the yen carry trade, borrow in low-yield JPY, invest in higher-yielding assets, had been a massive source of global liquidity. Estimates of total carry trade exposure ranged from $1 trillion to $20 trillion depending on what was included. On July 31, 2024, the BOJ surprised markets with a 15bp rate hike to 0.25% and signaled further tightening. USD/JPY fell from 155 to 143 in four days, an 8% move. The Nikkei 225 crashed 12.4% on August 5, 2024, its largest single-day drop since 1987. VIX briefly traded above 65 intraday before settling at 38 at the close, the highest closing print since March 2020. The global impact was asymmetric. US equities dropped 3% on August 5 but recovered within weeks. Crypto fell 15-20%. Gold and Treasuries rallied modestly on flight-to-quality. The fastest recovery in major sell-off history followed, by mid-August, the Nikkei had recovered most of the losses, and US equities made new highs by early September. The lesson was about the structure of carry trades. They provide positive returns consistently, until they don't, and then they unwind violently. BOJ tightening is a rare event after 30+ years of accommodation; the market had positioned for continued accommodation, and the unwind forced de-leveraging across every carry-funded trade simultaneously. The episode raised ongoing questions about hidden carry trade exposure and the potential for larger moves if BOJ normalization continued.
