Two closely watched events in Japan are colliding to create significant uncertainty for Bitcoin and global crypto markets. On one hand, the Bank of Japan (BOJ) is widely expected to raise interest rates on June 16 – a move that has historically triggered massive Bitcoin selloffs. On the other, BOJ Governor Kazuo Ueda was hospitalized on June 10, throwing the timing and certainty of that decision into doubt.
The brutal historical pattern
According to a widely shared analysis by crypto influencer Ash Crypto, every single BOJ rate hike since 2024 has been followed by a double-digit Bitcoin crash. The numbers are stark: March 2024 (-18%), July 2024 (-30%), January 2025 (-31%), and December 2025 (-32%). Some drops were immediate, while others unfolded over several weeks. The mechanism is the "yen carry trade" – investors borrow cheap yen to buy higher-yielding assets including Bitcoin. When Japan hikes rates and the yen strengthens, that trade becomes unprofitable, forcing liquidations.
Markets had been pricing in an 80–97% probability of a 25 basis point hike to 1%, the highest policy rate since 1995. Governor Ueda himself signaled tight policy in a June 3 speech, citing energy price pressures from Middle East tensions. Bitcoin was already battered, down over 50% from its October 2025 highs and having just lost the critical $62,000 support level.
Sudden twist: Ueda hospitalized
Then on June 10, BitcoinWorld reported that Governor Ueda had been hospitalized, with no official details on the nature of his condition. The BOJ confirmed he is receiving medical care, but his ability to chair the June meeting is now in question. Deputy governors Shinichi Uchida and Ryozo Himino would step in if needed. While the meeting is not expected to be canceled, Ueda’s personal influence on the board’s hawkish direction is significant. Markets immediately began repricing: the probability of a June hike declined, with analysts suggesting any tightening could be postponed to July or September.
What it means for Bitcoin
The uncertainty cuts both ways. If the pattern holds, another 18–32% drop could force BTC toward or below $49,000 – a level already flagged by Peter Brandt and prediction markets. However, the hospitalization may reduce the likelihood of an immediate hike, potentially softening the blow or delaying the carry trade unwind. The yen barely moved on the hospitalization news, but volatility is expected as more details emerge.
The crypto community is left asking the same question: will history repeat, or is this time different? With Bitcoin structurally fragile and macro forces shifting, the next few days will be a critical test.
