How are ETH, XRP, and BNB performing today? Actually, it might be related to a major event behind the scenes. On December 19, 2025, the Bank of Japan made a big move—raising the interest rate to 0.75%, the highest in nearly 30 years. Strangely, the market didn't crash; instead, it cheered. The Nikkei surged, and global risk assets took a deep breath. At first glance, it seemed like bad news, so why did it turn into a "super positive" signal? The key is that the market had already digested it. This rate hike wasn't a sudden shock; investors had priced it in long ago. Once the rate hike was announced, the uncertainty hanging over everyone’s heads disappeared. There's an even more important point—Japan's real interest rate is still negative. 0.75% sounds like a lot, but for a country with over 3% inflation, it's nowhere near enough. In other words, liquidity conditions remain loose, and the accommodative stance hasn't changed. Looking deeper, this rate hike is actually a signal: Japan's 30-year deflation problem is truly improving. Wages are rising, prices are increasing, and a healthy cycle is forming. The economic fundamentals are becoming more solid. The chain reaction in the market is quite interesting. Japanese stocks will directly benefit, especially in banking, consumer, and technology sectors. The yen will appreciate moderately, which is good for imports and won't wipe out global carry trades. Most importantly, for cryptocurrencies and other global risk assets, a healthy and predictable Japanese economy acts like a calming pill. In simple terms, this isn't the start of tightening, but a sign that the "patient" is truly recovering. The market's excitement isn't just about the rate hike itself, but that this huge uncertainty has finally been settled, and the outcome exceeded expectations.
