Bank of Japan Governor Kazuo Ueda shifted his tone decisively toward fighting inflation during a speech on June 3, citing energy price shocks tied to Middle East tensions as a primary concern that demands tighter monetary policy.
The implication is clear: a rate hike is almost certainly coming at the BOJ’s June 15-16 policy meeting. Markets are pricing in an 80-97% probability of a 25 basis point increase, which would lift Japan’s policy rate from 0.75% to 1% - the highest interest rate since 1995.
At the BOJ’s previous meeting on April 28, the board voted 6-3 to hold rates steady, with three members wanting to hike immediately. That dissent is meaningful at a central bank that historically prizes consensus.
What’s changed since April is the inflation picture. The BOJ has raised its core inflation forecast to 2.8% for fiscal year 2026 - nearly a full percentage point above its 2% target.
The foreign exchange reaction was immediate. The dollar slipped 0.3% against the yen following Ueda’s remarks, falling to 159.40 yen.
A stronger yen has cascading effects across global markets because of the yen carry trade. When the yen strengthens and Japanese rates rise, that trade becomes less attractive. Some investors unwind their positions, selling risk assets - including US stocks, emerging market bonds, and crypto - to pay back yen-denominated loans. In August 2024, a surprise BOJ rate adjustment triggered a sharp yen carry trade unwind that sent shockwaves through global equity and crypto markets.
For crypto investors, the logic chain is clear: higher Japanese rates lead to a stronger yen, which reduces the incentive for Japanese investors to seek yield in alternative assets like Bitcoin.
