Bank of Japan Holds Rate at 1% Amid Yen Intervention, Raising Bitcoin Carry‑Trade Risks

On 30 July 2026 the Bank of Japan kept its policy rate at 1 % while a fresh yen‑buying intervention was launched. The intervention briefly lifted the yen but the effect faded as market forces reversed the move. Japanese authorities acted alone, with no confirmed coordination with the U.S. Federal Reserve or Treasury.

The yen’s low interest rate continues to fuel a carry‑trade in which investors borrow yen to buy higher‑yielding assets such as Bitcoin. Although the interest‑rate gap between the United States and Japan remains large, it is narrowing, reducing the trade’s attractiveness. A similar BoJ rate hike in August 2024 triggered a sharp yen rally and a rapid sell‑off in Bitcoin and equities. Economists expect the BoJ to raise rates gradually later in the year, which could lead to an orderly unwind of the carry‑trade rather than a sudden shock.
