The Bank of Japan is expected to raise interest rates to 0.75% during its December 18-19 meeting. It would be the country’s first hike since January and the highest rate in nearly 30 years. While the move has been largely priced in by markets, some analysts are asking whether it could still weigh on Bitcoin and other crypto assets.
Concerns mostly focus on liquidity – specifically, the potential impact of rising yen rates on global capital flows. A stronger yen and tighter Japanese policy could, in theory, trigger a shift away from risk assets like crypto. However, many argue the real-world impact may be far more limited.

The Carry Trade Theory
Japan’s role in global markets is often tied to the yen carry trade, where investors borrow cheaply in yen and invest in higher-yielding assets abroad. Higher rates could reduce the appeal of this strategy and lead to some capital returning to Japan. That might lead to mild selling pressure across risk markets, including Bitcoin.
But the carry trade unwind theory isn’t new. Similar concerns were raised after Japan’s last rate hike in July 2024, when Bitcoin briefly dropped before recovering. The market has now had several months to adjust to BOJ’s shift, and most rate-sensitive investors have already repositioned.

Japanese Investors
Japan has over 13 million active crypto users, according to recent surveys – one of the largest retail bases in the world. But their total crypto holdings are estimated at around 5 trillion yen, or roughly $33 billion. That’s a small slice of the global crypto market, which is currently valued at well over $3 trillion.
Even if Japanese investors reallocate away from crypto in response to higher interest rates, the scale may not be enough to move global prices in a significant way.

Global Liquidity Still Matters More
Bitcoin tends to follow global liquidity more than individual central bank decisions. The bigger driver in the current cycle is the U.S. Federal Reserve, which has recently cut rates and signaled more easing ahead in 2026. That policy divergence could offset any tightening effect from Japan.
In that context, the BOJ’s expected move looks more like normalization than a shift that changes sentiment on its own. Bond yields in Japan have already risen for much of 2025, and the policy rate is catching up to those market levels. This limits the chances of a surprise.

Conclusion
While Japan’s upcoming rate hike may contribute to short-term volatility, especially around yen-related funding flows, the impact on Bitcoin is likely to remain limited. Domestic investors represent a small portion of global crypto capital, and the hike itself has been expected for months. Unless paired with a broader global tightening or unexpected policy shift, it is unlikely to change the long-term outlook for Bitcoin.
