USD/JPY was trading at 157.28-157.90 as of late November 5, needing to fall just 0.28-0.90 yen to breach 157.00 within ~16 hours. The pair has shown downward momentum (down 0.46-0.71% on the day) and yen strength from BoJ rate-hike signals, but faces headwinds from the 275-basis-point US-Japan rate differential that structurally supports dollar strength.
