Dollar falls for third straight day vs yen, down 0.7% to 157.04

A third straight daily decline pushing the dollar to a three-week low against the yen suggests momentum is building rather than a one-off wobble, though the item gives no catalyst to attribute it to. That gap matters: without a stated driver, the durability of the move is the open question, and whether the slide extends into a fourth session or stalls at this level is what to watch.
