Japan's central bank raised its short-term policy rate by 25 basis points to 1% on June 16, a level unseen since 1995. The move marks a continued departure from the nation's decades-long ultra-loose monetary policy.
The hike follows a previous increase to 0.75% in December 2025. With two rate increases in roughly six months, the Bank of Japan (BOJ) is signaling a sustained policy shift driven by persistent inflation, yen depreciation, and rising energy costs exacerbated by Middle East tensions.
In a notable development, Governor Kazuo Ueda was absent for the most significant tightening cycle in three decades, hospitalized for an infected liver cyst. The BOJ proceeded with the decision and indicated it plans further hikes while maintaining its bond purchase program to manage the long end of the yield curve.
The mechanics of the global yen carry trade are now under pressure. With yen short positions at a nine-year peak, a sharp rally in the currency could force traders to cover losses, creating a cascading unwind. This precise dynamic rippled across global markets in August 2024 following a previous rate hike, liquidating leveraged positions in equities and crypto alike.
For crypto investors, the normalization of policy in the last major economy with historically negative rates represents a macro risk. Bitcoin’s correlation to contracting global liquidity and the extreme positioning in yen shorts places the carry trade unwind scenario as a primary risk factor for the second half of 2026.
