Bitcoin and Major Altcoins Rally After Japan Rate Increase

The Bank of Japan’s policy stance matters well beyond the yen because low Japanese borrowing costs underpin the yen carry trade, a key source of liquidity for global risk assets. Faster BOJ tightening could prompt investors to unwind leveraged positions and pressure volatile markets, including cryptocurrencies. Persistently stronger-than-expected U.S. inflation adds another constraint by reducing the scope for monetary easing and keeping global financing conditions restrictive.

The BOJ kept its benchmark interest rate at 1% at its latest policy meeting, easing immediate concerns about a disorderly unwind of yen-funded trades. Bitcoin held near $64,000 as of July 31. The central bank’s governor nevertheless left open the possibility of accelerating rate increases and said inflation could move clearly above 2%, signaling that further tightening remains possible even as the latest decision offered short-term relief to markets.

The Bank of Japan’s interest-rate policy affects yen liquidity and the pricing of global risk assets. It could also influence carry trades financed with low-cost yen. Bitcoin is highly sensitive to funding costs and market risk appetite, so a shift toward tighter BOJ policy could prompt investors to reduce their cryptocurrency exposure and amplify price swings.

The Bank of Japan is expected to announce its latest rate decision on June 16, and traders are assessing whether a policy change could trigger another Bitcoin correction. Historical data show that Bitcoin has fallen by an average of about 22.4% after each BOJ rate increase since 2024, making the meeting a key risk event for the cryptocurrency market.

The Bank of Japan’s longstanding ultra-low interest rates have made the yen a major funding currency for carry trades. If rate hikes strengthen the yen, investors may unwind yen-funded positions and pull money from riskier assets. A similar unwind in August 2024 sent Bitcoin from $65,000 to $50,000 within a week, meaning a policy shift could also affect crypto assets such as XRP.

On April 28, 2026, the BOJ voted 6–3 to keep its policy rate at 0.75%, but three policy board members called for an immediate increase. Markets subsequently raised the probability of a June 16 rate hike to 74%. The dollar fell nearly 0.5% against the yen to 158.95, while Bitcoin dropped 0.6% on bitFlyer to 12.28 million yen. XRP also fell 3%, slipping below $1.40.
