The US just broke a decade-long hands-off approach to currency markets. Why now?
Two practical reasons:
1. A collapsing yen hurts American exporters — not just against Japan, but everywhere. When Japan's currency is artificially weak, US goods lose ground globally.
2. Japan's solo interventions usually mean selling Treasuries to buy yen. That pushes up US bond yields, which raises borrowing costs for the government, companies, and regular people back home.
Joint intervention sends a stronger signal. Markets noticed.
But here's the problem: Washington just tied itself to a strategy it can't control. Success depends entirely on Japan getting its act together — the Bank of Japan, the Finance Ministry, and the PM's office all rowing in the same direction.
Good luck with that.
Currency policy is always about trade-offs. The US just decided the status quo was more expensive than the risk of coordinating with Tokyo.
