The Bank of Japan left its benchmark rate unchanged at 0.75% on Tuesday, but the policy decision still turned more hawkish in the eyes of the market. A total of three board members voted for an immediate rate increase, the largest dissenting bloc since Kazuo Ueda became governor, fueling expectations that tightening could arrive before the end of the second quarter.
The central bank also revised its outlook in a way that reinforced those expectations. It lifted its core inflation forecast for the current fiscal year to 2.8%, while cutting its economic growth projection to 0.5%. That combination suggests policymakers are facing persistent price pressures even as the broader economy remains relatively soft.
Yen Strength Signals Growing Tightening Bets
Following the announcement, the yen strengthened and the USD/JPY pair fell nearly 0.5% to 158.95. The move reflected a rapid repricing in rate expectations, with traders assigning a 74% probability to a BoJ rate hike on June 16.
A stronger yen matters beyond the foreign exchange market. Because the yen has long been used as a funding currency, rising expectations for higher Japanese rates can trigger the unwinding of yen-funded carry trades. When that happens, liquidity can tighten across global markets, often putting pressure on equities and digital assets.
Bitcoin Faces Headwinds in JPY Terms
Bitcoin showed signs of that pressure as well. On bitFlyer, the BTC/JPY pair slipped 0.6% to 12.28 million yen. While the decline was modest, it underscored the market’s sensitivity to shifts in Japan’s policy outlook and their possible impact on broader risk sentiment.
For now, the BoJ has not moved rates higher, but the sharper internal split and upgraded inflation view have clearly changed market expectations. If the yen continues to appreciate and carry trades unwind further, Bitcoin and other risk assets could remain vulnerable in the near term.
