Bitcoin risks $64K breakdown as BOJ rate hike looms

The Bank of Japan's next policy move could trigger a yen carry trade unwind that pressures Bitcoin toward $64,000.

Bitcoin faces a slide toward $64,000 as the Bank of Japan weighs an interest rate increase that could unwind yen carry trades funding leveraged positions across global risk assets.

The yen has been trading near a four-decade low against the dollar, hovering around 156 per dollar as of the Asian session, with Japanese authorities on alert for intervention after the currency weakened past 160 earlier this year, according to market data.

A BOJ rate increase would strengthen the yen, forcing investors who borrowed yen at near-zero rates to buy back the currency and unwind positions in higher-yielding assets, including Bitcoin. The carry trade unwind could trigger forced selling across global risk markets, with Bitcoin's open interest and leveraged longs particularly exposed.

Bitcoin's $64,000 level represents a critical support zone, and a break below could accelerate selling toward lower levels. The BOJ's policy decision is expected in August 2026, with markets pricing in a potential hike as Japan's inflation remains above the central bank's 2 percent target.

Japan faces three simultaneous pressures: a yen at four-decade lows, inflation running above the central bank's target, and fiscal concerns from government spending that has undermined confidence in the country's debt trajectory. The BOJ's August meeting is now the focal point for global markets, with traders positioning for a potential rate hike that would mark a significant shift in Japan's monetary policy stance.

The yen's weakness has been a persistent theme through 2026, with the currency hitting a 40-year low against the dollar as the Federal Reserve maintained elevated rates. The interest rate differential between the US and Japan has made the yen an attractive funding currency for carry trades, where investors borrow yen cheaply and invest in higher-yielding assets globally.

Carry Trade Unwind Risk

The yen carry trade has been a significant source of global liquidity, with investors borrowing yen at ultra-low rates to fund positions in risk assets. Bitcoin, as a high-beta risk asset, has been particularly sensitive to changes in global liquidity conditions.

The transmission chain is clear: a BOJ rate hike would strengthen the yen, triggering carry trade unwinding, which would reduce global liquidity and pressure risk assets including Bitcoin. The $64,000 level represents a key support zone, and a break below could trigger further selling.

US Treasury yields have been elevated, with the dollar index near multi-month highs, adding to the headwinds for Bitcoin. Ethereum and other major cryptocurrencies are likely to move in tandem with Bitcoin, given the correlation across digital assets.

The BOJ's policy decision is the key event for Bitcoin in the near term. Markets are also watching US inflation data and Federal Reserve signals, as the Fed's rate path will influence the dollar-yen dynamic and, by extension, carry trade dynamics. Traders are also monitoring potential Japanese intervention in the currency market, as the yen's slide past 160 per dollar earlier this year prompted authorities to step in.
