The Bank of Japan raised its benchmark interest rate by 25 basis points to 1.0% on Tuesday — the highest level since 1995. This marks the third policy meeting since December 2025 where the BOJ has tightened. Policymakers also announced plans to end the reduction in government bond purchases after next spring.
The move is expected to reverse years of ultra-loose yen carry trades that flooded U.S. markets with cheap liquidity, particularly into high-valuation U.S. Treasuries and tech/AI stocks. Higher yen funding costs and anticipated yen appreciation are now forcing leveraged positions to unwind, creating near-term selling pressure on the Nasdaq and growth stocks, with increased market volatility likely.
Rising Japanese Government Bond yields may also prompt Japanese pension and insurance funds to repatriate capital by trimming U.S. bond holdings, further lifting U.S. borrowing costs.
While the single 25bp hike is modest and the U.S.-Japan yield gap remains, analysts warn that sustained BOJ tightening combined with a sharply stronger yen could trigger broader global liquidity withdrawal. This dynamic will be the key trend to watch in coming months.
