Created
Thesis
When a currency punches through the level where its government previously intervened to prop it up, and it keeps going, that tells you the move is driven by real flows rather than officials' words. The yen breaking 154 to its highest since February, with strategists calling 160 a firm ceiling on the dollar side, suggests sustained dollar weakness against Japan. Momentum in currency markets tends to persist for weeks, so riding the trend rather than fading it is the higher-probability play.
