Yen breaks above 153 per dollar, up 0.9% intraday

The yen's push past 153 signals renewed market conviction in policy divergence, but the move's durability hinges on whether BoJ rhetoric matches market pricing for tighter policy. This affects dollar-funded carry trades and Asian export competitiveness, making the pair's reaction to upcoming U.S. data the key test. Whether the BoJ actively validates the breakout or lets it run on speculation is the open question.
