On the surface, the Bank of Japan's interest rate moves look like their own monetary policy adjustments, but in reality, the impact on the crypto market is shockingly huge. Why? Because the yen carry trade that has fueled capital inflows into the crypto space for the past few years was effectively cut off by this rate hike. In the short term, we’ll see a combination of liquidity drying up, high-leverage liquidations, and market panic erupting all at once. But in the longer run, the post-panic lows may actually present an opportunity to get positioned—provided you can read the policy pace correctly and pick the right assets.

Let’s break down how this carry trade works. Japan’s interest rates were near zero, so global capital borrowed low-cost yen, swapped it for USD, and then poured it into high-volatility assets like Bitcoin and Ethereum, often leveraging up further through DeFi protocols to maximize returns. How big is this yen carry trade? Conservative estimates put it at $4 to $5 trillion, accounting for 20-30% of the new capital flowing into crypto. In other words, a huge chunk of crypto’s liquidity relied on this money-making game.

But once Japan hikes rates, the whole logic collapses. First, borrowing costs soar. What was nearly zero-interest yen loans now come with much higher rates, eating up the profits for those playing the interest rate spread. Second, the yen appreciates, which means you need more USD to exchange back into yen to repay your loans. Investors have no choice but to quickly sell off their crypto assets, convert to USD, and then into yen to pay back the debt. When large amounts of capital exit at once, crypto liquidity gets drained instantly.

Just look at the historical data to see how powerful this is. In August 2024, when Japan raised rates by 25 basis points, Bitcoin plummeted from $65,000 to $49,000—a drop of over 24% in a single month. In December 2025, just the expectation of a possible rate hike sent Bitcoin down $3,000 and Ethereum down 5%. And that’s not even the scariest part.

What’s even more deadly are those in crypto using 50x or 100x leverage. Rate hikes trigger price drops and currency fluctuations that easily set off forced liquidation thresholds. Once liquidations start, prices drop further, triggering even more liquidations—the classic death spiral. Single-day liquidations of over a billion dollars are the norm in this environment. And since Japan was the last major central bank to exit easy policy, its move in some ways signals the global liquidity turning point.
