The Bank of Japan raised its policy rate by 0.25 points to 1.25%, its second hike this year and the highest in decades. It shifted focus from pushing inflation to 2% toward keeping it stable around that level. Two of nine board members dissented, and the yen weakened briefly to about 157 per dollar before recovering to 156. For Thai businesses, the story is indirect: yen-linked import costs and Japan-bound export or tourism demand may move, so watch yen levels if you buy from or sell into Japan. No action is needed this week.
