The mainstream story about the weak yen is a cartoon. Everyone points to hedge funds borrowing cheap yen to buy Treasuries. Simple story. Easy headline. But Japan just spent tens of billions defending the yen directly in FX markets. Got almost nothing for it. Why? Because they were treating a symptom, not the disease. The real carry trade isn't a hedge fund trade. It's Japanese pension funds, insurers, institutional money, all quietly deciding that returns are better outside Japan than inside it. That's not speculation. That's domestic capital voting with its feet. And it explains something the textbooks can't: why BOJ rate hikes don't strengthen the yen. Under this framework, hikes can actually make it weaker. Japan may have finally named the real problem. Naming it and fixing it are two very different things.
