Yen Gains 1.63% on Dollar This Week as USD/JPY Ends at 153.73

The yen's gains were broad rather than dollar-specific, with the euro and sterling falling even harder against it — a sign this was yen strength, not just dollar weakness. That matters for carry-trade economics: a funding currency that appreciates sharply against every major peer forces positions to unwind, and the September 7 drop suggests that process may already have started. Whether the yen holds this range or gives it back is the open question, and it will likely hinge on whether the move reflects positioning or a genuine shift in rate expectations.
