Japan's central bank just pushed rates to 0.75%—the highest level in three decades. What happened next? Markets rallied hard overnight. Counterintuitive? Maybe on the surface. But here's the thing: markets don't react to what's written in headlines. They react to what they expect. The real threat wasn't the rate hike itself. Traders were bracing for something messier—a surprise move that could wreak havoc on yen carry trades and trigger a chaotic unwind. Instead, the BOJ delivered clarity and conviction. Clear communication, decisive action, no curveballs. That's exactly what markets craved. It removed the uncertainty premium that was pricing in chaos. When central banks are predictable and transparent, risk assets tend to breathe easier.
