Bank of Japan Lifts Rate to 31-Year High, Sparking Global Carry-Trade Unwind Fears

The Quick Take

• Bank of Japan raises its policy rate to a 31-year high, signalling a decisive end to the ultra-loose era and triggering yen carry-trade unwind pressure.
• The hike accelerates the reversal of the historically cheap yen funding that powered leveraged bets in US equities and emerging-market bonds.
• Global risk assets face a secondary shock as investors reassess the true cost of yen-funded positions built up over a decade.

The Bank of Japan's decision to lift rates to their highest level since 1995 marks a structural inflection point in global capital markets. For more than a decade, near-zero yen funding enabled carry traders to borrow cheaply in Japan and deploy into higher-yielding assets worldwide — a trade estimated to involve trillions of dollars at peak. As the BoJ gradually raises the cost of that funding, the mathematics of the carry reverses: positions that were profitable at 0% become marginal at 0.5% and potentially loss-making above 1%.

The market implication is a continued strengthening of the yen, which in turn forces margin calls on leveraged carry books and accelerates selling of the risk assets they were used to fund. Past episodes — notably the August 2024 carry unwind — showed how rapidly this can cascade into global equity drawdowns even in markets with no direct Japan exposure. With US equity valuations still elevated, any forced deleveraging from yen carry reversal amplifies existing fragility.

Forward signals to watch include BoJ governor commentary on the pace of further hikes, USD/JPY spot moves, and flows into Japanese government bonds from repatriated capital. A breach of 140 USD/JPY would likely catalyse a second leg of carry unwind. Equity investors should monitor positioning in Nikkei futures — a weakening yen tailwind has been a meaningful component of Japanese corporate earnings, and that wind is now shifting direction.
