Dollar/yen falls 1.2% to 154.38 as yen strengthens broadly

The sharp, broad-based yen strength marks a notable shift in FX dynamics, likely reflecting repositioning rather than a single catalyst. This matters for global markets because a firmer yen can pressure carry trades and influence risk sentiment across assets. The key question is whether this is a one-off correction or the start of a sustained trend, which would hinge on policy expectations and risk appetite. Watching whether dollar-yen holds below the 155 threshold or reverts toward 156 will signal the market's conviction.
