The Bank of Japan lifted its benchmark interest rate to 1% on June 16 — the highest level since September 1995. Bitcoin briefly dipped on the news but quickly recovered to trade near $66,000, close to its pre-announcement level. Previous BOJ rate hikes since March 2024 triggered Bitcoin drawdowns of 18% to 33%, but this time the move was almost fully priced in, with market-implied odds above 90% beforehand.
Why Bitcoin didn’t crash this time
The BOJ also paused the taper of its government bond purchases and committed to buying around 2 trillion yen of Japanese government bonds a month from April 2027, effectively capping long-term yields. That signal of continued monetary accommodation helped stabilize risk assets. The August 2024 surprise hike — which dropped Bitcoin from roughly $64,000 to $49,000 in 48 hours and erased about $600 billion in crypto market value — caught markets off guard. This time, traders had already priced in the tightening. A cooling of the US-Iran conflict also reduced energy-shock risk, removing one source of volatility.
The yen carry trade and crypto
The BOJ’s rate hike impacts Bitcoin through the yen carry trade. Investors borrow yen at low rates, convert to higher-yielding assets including crypto, and when rates rise, unwinding forces selling of risk assets. Bitcoin is often first to absorb selling due to 24/7 trading. But the carry trade’s leverage is lower than in 2024. Bank for International Settlements data showed yen-denominated foreign-currency credit contracted by 4.9% during 2025. Speculative yen short positions had climbed to roughly 115,000 contracts ahead of the meeting, the highest since November 2017, yet the unwind was orderly. The August 2024 hike triggered more than $1 billion in crypto liquidations; this time, no such cascade materialized.
Japan’s inflation puzzle
The BOJ is raising rates even though headline inflation was only 1.4% in April, the fourth straight month below the 2% target. Government measures — scrapping the gasoline tax and eliminating public high-school tuition — held down consumer prices. But Japan’s producer price index rose 6.3% year-on-year in May, the fastest pace in over three years, driven by oil costs tied to the US-Iran conflict. The BOJ worries energy prices will feed through to consumers, and the yen had slid back toward the 160-per-dollar level that previously triggered intervention. The rate increase passed 7-1, with Governor Ueda absent (recovering from a hospital stay) and Deputy Governor Shinichi Uchida fronting the press conference.
What comes next
After the decision, the Nikkei 225 added 0.46% and the yen firmed only marginally to 160.22 against the dollar. Japan’s weight in crypto comes from regulation and funding far more than raw trading volume. The BOJ’s next move will depend on how energy costs and wage growth evolve. For now, the bond-buying pledge gives markets a floor, but the yen’s slide and a potential flare-up in geopolitical tensions could force another hike sooner than expected.
