For decades, the yen's decline felt less like a market condition and more like a law of nature — a currency kept low by policy, exploited by speculators, and left to drift further from its former strength. Six weeks after touching a forty-year nadir against the dollar, that long consensus is beginning to crack, as capital flows home to Japan, carry trades unwind, and political winds from Washington add new weight to a trade that once seemed frictionless. The reversal is quiet for now, but in currency markets, quiet reversals have a way of becoming loud ones.
